<h2 id="Introduction">Introduction<a class="anchor-link" href="#Introduction">&#182;</a></h2><p>The geometry of helical gears and gear meshes is reviewed here.  Helical gears have similarities with spur gears, but fundamental differences do exist. Helical and spur gears similarities include:</p>
<ul>
<li>Mechanical power is transferred between rotating parallel bodies</li>
<li>Gear tooth geometry uses the involute curve to transmit motion</li>
<li>Plane of action is along the path tangent to the involute base circles</li>
</ul>
<p>The visualization of helical gears clearly shows the key geometric difference between it and a spur gear.</p>

Conceptually, this description is sufficient, but the mathematics of helical gear geometry must be considered in more detail to accurately define it.  This notebook will review the geometric attributes and their significance to the operation of helical gear pairs.</p>

    To understand the tooling and manufacturing processes used to make a helical gear, see the notebooks on gear tooling.  This notebook focuses on the resulting geometry of manufactured gears and gear pairs, not on how they are made.

<h3 id="Helix">Helix<a class="anchor-link" href="#Helix">&#182;</a></h3><p>To define the geometry of a helical gear tooth, we shall first define the <em>helix</em>.  A helix is a shape commonly associated with components such as coil springs, bolt threads, and gear hobs.  A helix contains certain characteristics that make it well suited for many applications, including the manufacturing and operation of mechanical gears.</p>

<p>For helical gears, a reference helix is defined by a <em>helix angle</em>, $\beta$, at the theoretical pitch diameter.  The sign of the helix angle determines the hand of the helix, with positive (+) being right-hand.  The diagram below illustrates the helix angle, not to be confused with the helix lead angle.</p>
<p><img src="./img/drivetrainhub_helix_angle.svg" alt="Helix curve" style="max-height: 300px; max-width: 100%"/></p>
<p style="text-align: center; font-weight: bold;">Helix angle of gear tooth</p><p>If we imagine unwrapping the helix curve along its helix angle, we can derive an expression for the helix pitch length as a function of helix angle and theoretical pitch diameter:</p>
$$p_\beta = \frac{\pi d}{\tan\beta}$$<p>and by acknowledging the helix pitch length as a constant regardless of diameter, the helix angle at an arbitrary diameter, $d_y$, is:</p>
$$\beta_y = \tan^{-1}\left(\frac{d_y \tan\beta}{d}\right)$$<div class="alert alert-block alert-info" style="box-shadow: 2px 2px 4px 0px rgba(0, 0, 0, .13);">
    <b>For the geometry of a helical gear, the helix angle varies as a function of radius.</b>  
    <br><br>
    This is observed in a helical gear tooth since the involute profile spans over a range of diameters.  This results in the helix angle at the base diameter being less than at the tip diameter.  This is particularly important when considering contact on the tooth surface and the resulting forces of a helical gear pair.

<p>A helix curve can be expressed in Cartesian coordinates with a set of parametric equations:</p>
$$x(t) = r \cos t$$$$y(t) = r \sin t$$$$z(t) = c t$$<p>where the helix pitch, i.e. the $z$ distance of one helix loop, equals $2 \pi c$.</p>

<h2 id="Gear-Teeth">Gear Teeth<a class="anchor-link" href="#Gear-Teeth">&#182;</a></h2><p>This section reviews the geometric properties of helical gear teeth. A working example is provided at the end of the section.</p>
<p>To understand the geometry of a helical gear, it is appropriate to consider both the <em>transverse</em> and <em>normal</em> planes.  These distinct planes exist due to the helical shape of the gear teeth.  In the case of spur gears, these planes are coincident since $\beta = 0\deg$.</p>
<ul>
<li><strong>Transverse plane</strong>: Plane normal to the axis of rotation, i.e. it is the plane of gear rotation.</li>
<li><strong>Normal plane</strong>: Plane normal to the gear tooth surface, oriented by the helix angle relative to the transverse plane. </li>
</ul>
<p><img src="./img/drivetrainhub_normal_and_transverse_planes.svg" alt="Transverse and normal planes" style="max-height: 250px; max-width: 100%"/></p>
<p style="text-align: center; font-weight: bold;">Transverse and normal planes</p><p>Lengths in the transverse and normal planes are related by helix angle according to:</p>
$$\cos\beta = \frac{\text{normal length}}{\text{transverse length}}$$

</table><p>It is also common to use addendum, dedendum, and profile shift coefficients of the basic rack or cutting tool instead of tip diameter, root diameter, and tooth thickness.  The former are better associated with the manufacturing process, while the latter are in reference to the manufactured geometry of a helical gear.</p>
<p>Notice tool tip radius is included in this set of input parameters.  It may seem out of place, but it is necessary to define since it relates directly to the manufacturing tooling responsible for the helical gear root geometry.  To understand this further, refer to the notebooks on gear tooling.</p>

Tooth thickness is important to tooth bending strength and is primarily a function of the gear module and profile shift.  For more about profile shift, see the blue info box below.</p>

    <b>Profile shift is in reference to common manufacturing processes used to make helical gears</b>.  
    <br><br>
    Physically, profile shift refers to the distance between a gear's theoretical pitch diameter and the cutting tool datum line.  Without consideration for the manufacturing process, it is difficult to assign physical meaning to profile shift, in which case considering the gear tooth thickness directly is more intuitive.
</div><h4 id="Tooth-tip-thickness">Tooth tip thickness<a class="anchor-link" href="#Tooth-tip-thickness">&#182;</a></h4><p>The tooth tip thickness is of particular interest since it can fracture if too thin.

Without constraining it, the tooth tip thickness will trend towards zero, a condition known as <em>tooth peaking</em>.</p>

<h4 id="Form-Diameter">Form Diameter<a class="anchor-link" href="#Form-Diameter">&#182;</a></h4><p>The form diameter refers to the diameter at the boundary point, $\rm{F}$, of the involute and root profiles.  In the simplest case, the form diameter boundary point is the point of tangency between the involute and root profiles.  For a rack generation cutting tool, such as a hob, the tool cut point at boundary point $\rm{F}$ is the tool tip point tangent to the rack profile.  For a better understanding, refer to the notebooks on gear tooling.</p>

<h4 id="Undercut">Undercut<a class="anchor-link" href="#Undercut">&#182;</a></h4><p>Undercut of a helical gear tooth root is a consequence of the cutting tool removing a portion of the involute profile instead of being tangent to the involute.

<p style="text-align: center; font-weight: bold;">Undercut root fillet and boundary point</p><p>Undercut can be related back to certain geometric properties of the gear.  Undercut caused by a rack generation cutting process can be avoided with positive profile shift, thus the following condition is formulated to avoid undercut:</p>
$$x \geq h_a^* - \frac{z \sin^2\alpha_t}{2 \cos\beta}$$<p>Similarly, a condition for minimum number of teeth to avoid undercut is:</p>
$$z \geq \frac{2 \cos\beta}{\sin^2\alpha_t}\left(h_a^* - x^*\right)$$<p>More complicated cases of undercut are possible with protuberance cutting tools, but are outside the scope of this notebook.  To learn more about the influence of protuberance, see the notebooks on gear tooling.</p>

    <b>Gear designers should avoid undercut of <i>finished</i> teeth since it reduces tooth bending strength.</b>
    <br><br>
    Depending on the application requirements, it may not always be possible to avoid undercut, e.g. if a large single-stage gear ratio is required.  In such cases, other failure modes, such as gear scuffing, may become a greater concern due to high pitch line velocities.
</div><div class="alert alert-block alert-info" style="box-shadow: 2px 2px 4px 0px rgba(0, 0, 0, .13);">
    <b>Undercut is intentionally added to the <i>pre-finished</i> teeth of many medium-to-high quality gears that undergo a finishing process.</b>
    <br><br>
    A <i>protuberance</i> cutting tool can be used to add undercut to gears that would otherwise not have it.  Pre-finished undercut is beneficial to the finishing process because it provides <i>finishing stock</i> material to be removed and provides an exit path for the finishing tool without interfering with the root.  Upon removal of the finishing stock, the finished involute profile is tangent to the root fillet.

<ul>
<li><strong>Radial backlash, $j_r$</strong>: Linear length of backlash along the gear mesh center distance.</li>
<li><strong>Circumferential backlash, $j_{tt}$</strong>: Arc length of pitch circle in the backlash region.</li>

<h4 id="Active-Profile">Active Profile<a class="anchor-link" href="#Active-Profile">&#182;</a></h4><p>During the mesh cycle of a helical gear pair, the involute tooth profiles have a starting point and ending point.  The region of involute profile between these start and end points is termed the <em>active profile</em>.  Intuitively, the start and end points are referred to as the <em>start of active profile</em> (SAP) and <em>end of active profile</em> (EAP).  Diameters or roll angles are typically used to indicate the SAP and EAP, with SAP as the lower value by convention.</p>
<p>The active profile can be understood by visualizing the active portion of the line of action in a transverse section of a helical gear pair.  This active segment may be called the <em>contact plane</em> or <em>plane of contact</em>.</p>
<p><img src="./img/drivetrainhub_active_line_of_action.svg" alt="Active contact region in the line of action for a helical gear pair" style="height: 300px; max-width: 100%"/></p>
<p style="text-align: center; font-weight: bold;">Contact plane in the line of action</p><p>From the figure, line $\overline{\text{AE}}$ is the active profile trace in the line of action, thus gear $1$ SAP and EAP are at points $\rm{A}$ and $\rm{E}$, respectively.  Due to the convention of SAP always being the lower value, the SAP and EAP of gear $2$ are at points $\rm{E}$ and $\rm{A}$, respectively.  An expression for transverse pressure angle at the point of contact can be derived as:</p>
$$\alpha_{t\rm{Y1}} = \tan^{-1} \left( \tan\alpha_w - \frac{z_2}{z_1} \left( \tan\alpha_{t\rm{Y2}} - \tan\alpha_w \right)\right)$$<p>where $\rm{Y}$ indicates an arbitrary point of contact, thus $\alpha_{t\rm{Y2}} = \alpha_{ta2}$ can be used to calculate the SAP of gear $1$.  The contact plane length is calculated as:</p>
$$\overline{\rm{AE}} = r_{b1} \left( \tan\alpha_{ta1} - \tan\alpha_w \right) + r_{b2} \left( \tan\alpha_{ta2} - \tan\alpha_w \right)$$<p>It is worth noting that length $\overline{\text{BE}}$ equals the transverse base pitch.  Notice the importance of equal base pitch for two gears to achieve the desired engagement of gear teeth as they rotate.  In actual manufactured helical gears, imperfect base pitch exists and contributes to uneven load share between gear teeth, which leads to higher-than-nominal loads on certain teeth and may cause amplitude modulated vibrations and noise.</p>

    <b>End of active profile does <i>not</i> always coincide with the tip diameter or tip chamfer diameter.</b>
    <br><br>
    In cases of a gear tooth being undercut, the boundary point of the root fillet and involute can reduce the active profile region and cause loss of contact before the mating gear involute has reached its tip diameter.

<h4 id="Contact-Path">Contact Path<a class="anchor-link" href="#Contact-Path">&#182;</a></h4><p>A helical gear tooth surface is constructed from a circle involute swept along a helical path, creating an <em>involute helicoid</em>.  The circle involute is a curve of continuously varying radius.  Therefore, when two opposing helical gear tooth surfaces are brought into contact, the contact occurs along a line.</p>
<p>Since a helical gear mesh has multiple teeth in contact during a mesh cycle, multiple lines of contact exist.  By examining the geometric properties of the contact lines in the plane of action, attributes of contact through a mesh cycle can be understood.</p>

<p style="text-align: center; font-weight: bold;">Contact plane with contact lines of meshing helical gear teeth</p><p>By following the convention of the previous figures for direction of rotation, tooth flanks begin contact at point $\rm{A}$ and end contact at point $\rm{E'}$.  As the contact lines move across the plane while the gears roll through mesh, the total length of the contact lengths is not necessarily constant.  This is considered in more detail, but first we must define contact ratios.</p>

<h4 id="Contact-Ratio">Contact Ratio<a class="anchor-link" href="#Contact-Ratio">&#182;</a></h4><p>Contact ratio is defined as the mean number of teeth in contact through a mesh cycle.  For a helical gear pair, these contact ratio definitions are used:</p>
<ul>
<li><strong>Transverse contact ratio</strong>:  Mean number of teeth in contact in the transverse plane.</li>
<li><strong>Axial contact ratio</strong>:  Mean number of teeth in contact in the axial plane.  Also known as the <em>overlap ratio</em>.</li>
<li><strong>Total contact ratio</strong>: Mean number of teeth in contact in the plane of action.</li>
</ul>
<p>The contact ratios can be derived from the relationship of contact path lengths and pitch lengths, as illustrated in the previous figure.  Transverse contact ratio is the ratio of transverse contact path length to transverse base pitch, calculated as:</p>
$$\epsilon_\alpha = \frac{\overline{\rm{AE}}}{p_{bt}} = \frac{z_1 \left(\tan\alpha_{a1} - \tan\alpha_w\right) + z_2 \left(\tan\alpha_{a2} - \tan\alpha_w\right)}{2 \pi}$$<p>where it is assumed that tip diameter is the EAP.  Axial contact ratio is the ratio of effective facewidth to axial pitch, calculated as:</p>
$$\epsilon_\beta = \frac{b}{p_a} = \frac{b \sin\beta_b}{\pi m_n \cos\alpha_n} = \frac{b \sin\beta}{\pi m_n}$$<p>where it is obviously zero for spur gears and increases with helix angle.  Lastly, total contact ratio is calculated as the sum of transverse and axial:</p>
$$\epsilon_\gamma = \epsilon_\alpha + \epsilon_\beta$$

<h4 id="Contact-Variation">Contact Variation<a class="anchor-link" href="#Contact-Variation">&#182;</a></h4><p>As a helical gear pair rolls through a mesh cycle, the sum of contact line lengths can vary.  This can be visualized with the previous figure by viewing the contact lines as moving across the plane of action during a mesh cycle.  Remember, each contact line represents a pair of meshing teeth.  The mean sum of contact line lengths can be expressed as:</p>
$$l_{D\rm{mean}} = \frac{b \epsilon_\alpha}{\cos\beta_b}$$<div class="alert alert-block alert-info" style="box-shadow: 2px 2px 4px 0px rgba(0, 0, 0, .13);">
    <b>Axial contact ratio, $\epsilon_\beta$, is responsible for the variation in the sum of contact line lengths.</b>
    <br><br>
    This is most obvious for the case of zero overlap ratio, $\epsilon_\beta = 0$, where the total length of contact lines varies instantaneously by $b$ due to the start or end of contact for a given tooth pair.  For example, a spur gear pair with a contact ratio of $1.4$ will have exactly $1$ tooth pair in contact 60% of the time and $2$ tooth pairs in contact 40% of the time, i.e. for steady state operation.
    <br><br>
    For helical gears, the overlap ratio is always non-zero, $\epsilon_\beta \neq 0$, which causes the total length of contact lines to vary more gradually through a mesh cycle.  The higher the overlap ratio, the less variation in total length of contact lines relative to the mean value.  The special case of an integer overlap ratio results in zero variation.  Less variation is desireable for reducing dynamic tooth loads and noise.
</div><p>The minimum value for the sum of contact line lengths is of particular interest because it is when the gear teeth experience maximum load.  Its value depends on the sum of contact ratio remainders.  For $n_\alpha + n_\beta \leq 1$, it is calculated as:</p>
$$l_{D\rm{min}} = l_{D\rm{mean}} \left( 1 - \frac{n_\alpha n_\beta}{\epsilon_\alpha \epsilon_\beta} \right)$$<p>and for $n_\alpha + n_\beta \gt 1$, it is calculated as:</p>
$$l_{D\rm{min}} = l_{D\rm{mean}} \left[ 1 - \frac{(1 - n_\alpha)(1 - n_\beta)}{\epsilon_\alpha \epsilon_\beta} \right]$$

<h4 id="Sliding-Velocity">Sliding Velocity<a class="anchor-link" href="#Sliding-Velocity">&#182;</a></h4><p>While meshing helical gear teeth are in a state of pure roll at the pitch point, the tooth surfaces are sliding against each other in the approach and recess regions in the line of action.  This sliding action is why cylindrical involute gearing is sometimes described as analogous to a cam-follower mechanism.  Gear tooth sliding is important to gear mesh efficiency, wear, scuffing, and noise.</p>

<p style="text-align: center; font-weight: bold;">Contact point linear velocity vectors in the line of action</p><p>In the figure above, the linear velocities of contact point $\rm{Y}$ are denoted by $v_\rm{Y1}$ and $v_\rm{Y2}$ for gear $1$ and gear $2$, respectively.</p>
$$v_\text{Y1} = r_\text{Y1} \omega_1$$$$v_\text{Y2} = r_\text{Y2} \omega_2$$<p>The components of velocity normal to the line of action, and therefore tangential to the involute tooth profiles, are denoted by $v_\rm{Yt1}$ and $v_\rm{Yt2}$.</p>

Sliding velocity is the relative tangential velocity of the tooth profiles, calculated as:</p>
$$v_\text{R1} = v_\text{Yt1} - v_\text{Yt2}$$$$v_\text{R2} = v_\text{Yt2} - v_\text{Yt1}$$<p>where $v_\text{R1}$ is interpreted as the sliding velocity of the driving gear relative to the driven gear.  Notice the equal and opposite relationship between the sliding velocities, $v_\text{R2} = - v_\text{R1}$.  If sliding velocity is plotted as a function of mesh cycle, it can be observed that the direction of sliding reverses at the pitch point.</p>
<h4 id="Specific-Sliding">Specific Sliding<a class="anchor-link" href="#Specific-Sliding">&#182;</a></h4><p>Specific sliding is the ratio of sliding velocity to the velocity of the contact point in the direction of sliding, i.e. tangential to the involute profile or normal to the line of action.  It is a unitless metric dependent only on the gear mesh geometry, i.e. regardless of angular velocities, making it useful for gear design.</p>

    <b>Sliding is of greatest concern at the SAP and EAP, when a pair of helical gear teeth are entering or exiting the mesh cycle.</b>

    Sliding velocity increases as the distance from the pitch point increases in the line of action.  The points of contact furthest from the pitch point are the SAP and EAP.  In cases of high profile shift, the pitch point may be at or below SAP and therefore sliding velocity does not reverse direction, but EAP sliding velocity may be excessive and lead to scuffing.

<h3 id="Transverse-Plane">Transverse Plane<a class="anchor-link" href="#Transverse-Plane">&#182;</a></h3><p>In the transverse plane, i.e. the plane of rotation, the key items of geometric design for spur and helical gears are:</p>
<ol>
<li>Gear ratio</li>
<li>Center distance</li>
<li>Sum of profile shifts</li>
</ol>
<p>The gear tooth forms are determined as a function of these items.  Tooth depth may also be considered as a function of the desired bottom clearance.  The tooth form design must ultimately relate back to the tooling and work piece used to manufacture the gear, namely the profile shift, addendum, and dedendum coefficients.  Additionally, tool tip radius and its influence on root strength and the active profile may be studied.</p>
<p>As you can see, full consideration of the detailed tooth forms can cause the design space to become very large.  Usually, a designer has several constraints that can be imposed to help reduce the design space, allowing for quicker exploration of viable design candidates.</p>
<p>In the working example provided at the end of this section, the design space is limited based on a required center distance, target gear ratio, and sum of profile shifts.  With these constraints, a human can reasonably explore and interpret the design space.  Without these constraints, it is advised that optimization algorithms be used with computational methods to efficiently explore the very large design space.</p>

<h3 id="Axial-Dimension">Axial Dimension<a class="anchor-link" href="#Axial-Dimension">&#182;</a></h3><p>Adding to the design space are the parameters associated with the axial dimension: facewidth, $b$, and helix angle, $\beta$.  Recall from a prior section that the axial contact ratio is solely responsible for the variation in total length of contact lines, $\Delta l_D$, through a mesh cycle.  Nominally, this variation will be zero to minimize the gear mesh dynamic loads and noise, calculated as:</p>
$$\beta = \arcsin{\frac{k \pi m_n}{b}}$$<p>where $k$ must be an integer to achieve $\Delta l_D = 0$.</p>
<p>Unfortunately, the use of helical teeth is not entirely beneficial.  Disadvantages of helical gears compared to spur gears include:</p>
<ol>
<li>Axial forces occur at the gear mesh and must be reacted by bearing supports. </li>
<li>Normal module is reduced for a given package size, but the normal force increases.</li>
<li>Sliding between gear flanks occurs over a larger surface area, reducing efficiency.</li>
</ol>
<p>Unless dynamic loads and noise are of little concern, the benefits of helical gearing outweigh its disadvantages.</p>
<div class="alert alert-block alert-info" style="box-shadow: 2px 2px 4px 0px rgba(0, 0, 0, .13);">
    The axial contact ratio is <i>not</i> affected by center distance or tooth depth, a beneficial trait when designing the helix angle to minimize dynamic loading.
