Gear Pair

(Template Builder) Driveline Components -> Gear Pair -> New/Modify Comprehensive Help

Defines a gear pair. See Gear Pairs.

This dialog box has two modes: create and modify.

For the option:	Do the following:
Tips on Entering Object Names in Text Boxes.
Gear Pair Name	Enter a string that defines the name of the gear pair.
Input Shaft	Enter the name of the input shaft.
Output Shaft	Enter the name of the output shaft.
Input Reference Frame	Specify the name of the construction frame, located on the input shaft, that defines the direction around which the input gear rotates and the position on the input shaft of the input gear.
Output Reference Frame	Specify the name of the construction frame, located on the output shaft, that defines the direction around which the output gear rotates and the position on the output shaft of the output gear. Note: In order for the inplane primitive joint (carrier_to_o_shaft) to be acting in the right direction, the Output Reference Frame should be oriented in the following way: 1. Z-axis should be along rotational axis (standard) 2. X-axis must point towards the Input Reference Frame
Gear Number	Enter a number that defines the gear number. Do not specify the same number for more than a gear pair. Adams Driveline uses this parameter to create a function that activates the synchronizer force only when the transmission demand variable is equal to the gear number.
Configuration	Select the type of connection for the gear-pair component: ■Input Gear to Shaft - The input gear is permanently engaged to the input shaft and the synchronizer is located on the output shaft. ■Output Gear to Shaft - The output gear is permanently engaged to the output shaft and the synchronizer is located on the input shaft.
For more information on the following four parameters, see About Rotational Backlash components.
Backlash	Enter a real number that defines the rotational backlash allowed in the gear mesh. Adams Driveline uses this value to model the contact force between the two gear parts. Adams Driveline always applies backlash on the output shaft.
Contact Stiffness	Enter a real number that defines the contact stiffness. Adams Driveline uses this value to model the contact force between the two gear parts, once the maximum allowed backlash is reached.
Contact Damping	Enter a real number that defines the contact damping. Adams Driveline uses this value to model the contact force between the two gear parts, once the maximum allowed backlash is reached.
Sharpness Factor	Enter a real number that defines the Sharpness Factor. Adams Driveline uses this value to model the contact force between the two gear parts, once the maximum allowed backlash is reached.
Invert output direction from input direction	Specify if you want the two gear parts to rotate in the same direction or not.
Reduction Ratio Method	Select either: ■explicit ■scaled off gears
If you select explicit, Adams Driveline displays the following option:
Ratio	Specify the gear ratio as a real number. Adams Driveline updates the gear graphics accordingly.
Input Gear/Output Gear	Enter two gears geometries. Adams Driveline updates the two gear geometries to be consistent with the ratio value you specified above.
If you select scaled off gears, Adams Driveline displays the following options:
Input Gear/Output Gear	Enter the diameter of the two gears to define the gear ratio. Adams Driveline automatically calculates the ratio using the two gear radii.
If a synchronizer component exists in the gear pair, Adams Driveline displays the following two fields and options:
Synchronizer Name	The (short) name of the attached synchronizer is shown. The user can change the synchronizer input data via the modify button on the right side of the field.
Synchronizer Active	If set to yes, the synchronizer shown in the synchronizer name field gets activated and the perpendicular primitive joint which permanently engages the gear to the shaft gets deactivated. It is vice versa if the option is set to no.
	Select to display the Modify Entity Comments dialog box, where you can add multi-line comments to any entity to describe its purpose and function. Learn about Recording Comments.
