Create/Modify Gear

(Adams Driveline Template Builder) Driveline Components → Gear Tool → Spur/Helical Gear Element → New/Modify            Shared Dialog Box
Creates or modifies a Gear.
 
For the option:
Do the following:
Gear Name
If creating a gear, enter a name for it.
If modifying a gear, enter its database name.
Property File
You can:
■Use an existing property file by specifying the name of the property file that contains the parameter values of the component.
When you specify a property file, your template-based product automatically updates the dialog box with the values from the property file.
■Create a new property file by specifying a new name. When you specify a new name, your template-based product displays the database path that it will use to create the new file.
Your template-based product always creates a new property file in the default writable database.
Editable
Select if you want to modify any of the values supplied by the property file you selected.
Attachment To
Select one of the following:
■Part - Specify a part and a construction frame. Learn about Construction Frames. Your template-based product creates a marker on the attachment part at the location and with the same orientation as the construction frame. (Learn about Markers.) The marker is the J marker of the joint.
■Marker - Specify a marker. The marker is the J marker of the joint.
If you set Attachment To to Part, your template-based product displays the following options:
Attachment Part
Enter the name of the part to which the gear will be constrained.
Coordinate Reference
Specify the location and orientation of the gear by entering the name of a construction frame.
If you set Attachment To to Marker, your template-based product displays the following option:
Coordinate Reference
Specify the location and orientation of the gear by entering the name of a marker.
Geometry tab
Module*
Enter the module of the gear. The module is equal to 1/diametral pitch.
Number of Teeth*
Enter the number of teeth of the gear. Your template-based product computes the pitch diameter based on the equation:
pitch diameter = module * number of teeth
Tooth Angle*
Enter the tooth angle of the gear. This angle is also referred to as the pressure angle. Your template-based product uses this angle to specify the tooth profile, which is based on the involute function.
Helix Angle*
Enter the helix angle of the gear. For straight gears, enter 0.
The helix angle must be: -50d helix angle 50d
Gear Width*
Enter the width of the gear.
Addendum Factor*
Enter the addendum factor. Your template-based product uses this factor to compute the tip (outer) diameter of gear:
tip diameter = pitch diameter + 2 * module * (addendum factor + addendum modification coefficient)
Dedendum Factor*
Enter the dedendum factor. Your template-based product uses this factor to compute the root (foot) diameter of the gear:
root diameter = pitch diameter - 2 * module * (dedendum factor - addendum modification coefficient)
Addendum  Mod. Coefficient*
Enter the addendum modification coefficient. Your template-based product uses this coefficient to describe the profile shift of the gear.
Delta Tooth Thickness*
Enter the delta tooth thickness of the gear. This thickness is the deviation of circular thickness at the pitch circle from the standard tooth thickness of an ideal gear.
Mass Properties tab
Mass*
Enter the mass of the gear part.
The part is located in the center of the gear, with the z-axis as the rotational axis.
Ixx/Iyy/Izz*
Enter the values that define the principal mass-inertia components of the gear part.
Ixy/Izx/Iyz*
Enter the values that define the deviational (cross-product) mass-inertia components of the gear part.
CM Location Relative to Part* (optional)
Enter the x, y, and z values of the location offset. You can offset the center of mass and inertia markers of the gear part a specified distance from the gear part's location.
Torsional Spring tab
The following torque function defines the rotational spring-damper: 
T = - az * Torsional Stiffness - wz * Torsional Damping 
where: 
■az - Angular displacement 
■wz - Angular velocity
Torsional Stiffness (optional)
Enter the stiffness of the rotational spring-damper. The stiffness is in force units * length units/angle units.
Torsional Damping (optional)
Enter the damping coefficient of the rotational spring-damper. The damping is in force units * length units * time units/angle units.
Fixed Gear
Select one of the following:
■Yes - Fixes the gear to the attach part.
■No - Constrains the gear to the attach part with a rotational joint.
Activate Torsional Spring (enabled if gear is not fixed)
Select one of the following:
■Yes - Adds a torsional spring to the rotational joint.
■No - No torque is acting on gear rotational axis.
Select to display a dialog box where you can add multi-line comments to any entity, to describe its purpose and function. Your template-based product displays different comments dialog boxes, depending on the entity type for which you want to record comments:
■If recording comments for modeling entities in Standard Interface, your template-based product displays the Entity Comments dialog box.
■If recording comments for any other entity type, your template-based product displays the Modify Comment dialog box.
Learn about Recording Comments.
Select to view property file information. By default, your template-based product displays this information in the Information window, but you can choose to display the information in a text editor.

Note:  
*Parameter values are stored in the property file. You can only update these values when Editable is selected.
