Spur Gear - Simplified Method

This method calculates the gear forces and backlash between the gear pair analytically. It is useful when friction is neglected. The contact force calculation is fast because of its analytical approach.
 
For the option
Do the following
Module (Normal Plane)
Enter a value for the module expressed in the normal plane (MN). The module is the pitch diameter divided by the number of teeth.
Pressure Angle (Normal Plane)
Enter a nominal pressure angle (α) in current modelling Units (default value = 20.0 deg) expressed in the normal plane. The pressure angle is the angle between the line of action and the common tangent to the pitch circles at the pitch point is the pressure angle. Enter a real value that defines the gear pressure angle.
Axis of Rotation
Axis of Rotation of Gear 1 and Gear 2 can be one of the following:
■Orientation
■Pick (Marker)
■Global Z
■Global X
■Global Y
GEAR PAIR
Name
Enter the name for Gear 1 and Gear 2.
■New
■Existing: Use the Select Gear options to load the existing gear.
Center Location
Enter the coordinates or Pick (Markers, View location and so on.)
No. of Teeth
Enter the number of teeth (Z) for Gear 1 and Gear 2.
Gear Width
Enter the face width for Gear 1 and Gear 2 (only used for graphics).
Bore Radius/Ring Radius
Enter the radius for the hole in the external gear or outer radius for internal gears.
Note: Internal gear option is supported only for gear 2.
Important:  
The involute definition and tooth modification are not applicable to the simplified method gear type. However, if you edit the parameter with individual gear modify dialog box then this option will appear.
Geometry Settings
■Profile points
Defines the number of points for the half tooth profile (the other half is mirrored) through which a curve is fit.
Note: Increasing this value may improve resolution of geometry especially for larger gear teeth but at the expense of increased time to create gear pair.
■Layers
Defines the number of "layers" of the helical gear width should be divided into. This number should increase with increasing helix angle and gear width. For helix angle equal to 0 degrees (spur gear) this value will be automatically set to 2, otherwise the value specified in this field is used.
Note: Increasing this value may improve resolution of geometry especially for larger gear teeth but at the expense of increased time to create gear pair.
