Description

This and the linked website(s) are under construction since 8.3.2020. I try to fill the content quickly in addition to my job. Therefore please have a little patience. @bavariaSHAPE

Due to the favourable meshing ratio and the relatively simple production, involute gearing is the most common tooth form in mechanical engineering. Gear wheels can be found wherever movement and force are to be transferred from one part to another. For example, they can be found in machines, cars, watches or household appliances. The movement is often transferred directly from one gear wheel to the other, but sometimes also via a chain. In addition, the direction of rotation can be changed. It is also possible to change a radial movement into a linear one via Involute Rack ( Create an Involute rack).

From left to right: Spur gearing, helical gearing, double helical gearing

Usage

  1. Switch to the FCGear Workbench.
  2. Invoke the command several way:
  3. Change the gear parameter to the required conditions (see Properties → Data below).

Data

Base

  • DataPlacement: Placement is the location and orientation of an object in space.
  • DataLabel: User name of the object in the Tree view.

computed

  • Datadw: Ptch diameter (not changeable, is calculated automatically).

gear_parameter

  • Databeta: With the helix angle β a helical gear is created (positive value = rotation direction right, negative value = rotation direction left).
  • Dataclearance:
  • Datadouble_gear: True = creates double helix gear; False = in conjunction with the helix angle β a helix gear is generated (see also the information in Note)

  • Databackslash: Backlash, also called lash or play, is the clearance between the teeths of two gears.
  • Datareversed_backslash: true = backlash decrease; false = backlash increase (see also the information in Note).

View

The parameter descriptions of the View tab will be found in Property editor, further below at Example of the properties of a PartDesign object.

Notes

  • To use the double helical gearing (Properties → gear_parameter → double_helix), the helix angle β (Properties → Data → gear_parameter → beta) for the helical gearing must first be entered.
  • If there are several gears, pay attention to which gear is set to {reversed_backslash.
