Figure 1  Spur Internal Gear property page [Geometry Data page]

 

The Spur Internal Gear property page is shown in Figure 1. The parameters are explained below. In order to understand the geometry, refer to Geometric Entities

 

     Module: Enters the module of the gear.

     Pressure Angle: Enters the pressure angle of the gear.

     Number of Teeth: Enters the number of teeth. The maximum number of teeth of gear is 400.

     Gear Width: Enters the width of the gear.

     Parameter Type: two methods are supported to define the Addendum and Dedendum.

    Factor: Defines the addendum and dedendum as factors. For more information, click here.

Addendum Factor: Enters the factor to define the addendum.

Dedendum Factor: Enters the factor to define the dedendum.

    Addendum Radius & Whole Depth: Defines the addendum and dedendum as addendum radius and whole depth. For more information, click here.

Addendum Radius: Enters the addendum radius for the gear.

Whole Depth: Enters the whole depth as summation for the addendum and dedendum.

 

     Addendum Modification Coef.: Enters the coefficient to define the addendum.

     Delta Tooth Thickness: Enters the delta value to define the tooth thickness. For more information, click here.

     Information: Shows the calculated values for Pitch Radius, Tip Radius, Base Radius, Root Radius, and Circular Tooth Thickness.
