Figure 1 Worm property page [Geometry Data page]
The Worm property page is shown in Figure 1. The parameters are explained below.
•Module: Enters the module of the gear.
•Number of Start: Enters the number of threads on the worm. For more information, click here.
•Bore Diameter: Enters the bore diameter of the worm.
•Face Width: Enters the face width of the worm.
•Hub Diameter: Enters the hub diameter of the worm.
•Hub Width (R): Enters the hub width for the right of the worm.
•Hub Width (L): Enters the hub width for the left of the worm.
•Pressure Angle: Enters the pressure angle of the gear.
•Total Length: Shows the total length of the worm.
•Pitch Diameter: Enters the pitch diameter of the worm. This can define a lead angle. For more information, click here.
•Lead Angle: Enters the lead angle of the worm. This can define a pitch diameter. For more information, click here.
•Diameter Factor: Enter the factor for Pitch Diameter. This can define a pitch diameter and lead angle. For more information, click here.
•Hand of Thread: Defines the direction of thread as L or R.
•Outside Diameter: Shows the outside diameter of the worm.
•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.
o Addendum Factor: Enters the factor to define the addendum.
o 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.
o Addendum Radius: Enters the addendum radius for the gear.
o Whole Depth: Enters the whole depth as summation for the addendum and dedendum.
•Adden. Mod. Coeff.: Enters the coefficient to define the addendum.
•Delta Tooth Thick.: Enters the delta value to define the tooth thickness. For more information, click here.
•Information: Shows the calculated values for Pitch Diameter, Outside Diameter, Root Diameter, and Tooth Thickness.
