FCGear InternalInvoluteGear

Usage

 * 1) Switch to the [[Image:FCGear_workbench_icon.svg|16px]] FCGear Workbench.
 * 2) There are several ways to invoke the command:
 * 3) * Press the button in the toolbar.
 * 4) * Select the option from the menu.
 * 5) Change the gear parameter to the required conditions (see  below).

Properties
An FCGear InternalInvoluteGear object is derived from a Part Feature object and inherits all its properties. It also has the following additional properties:

Data

 * : Default is . Change of the involute profile. Changing the value can lead to unexpected results.


 * : Default is . Value of the gear width.
 * : Default is . Module is the ratio of the reference diameter of the gear divided by the number of teeth (see also the information in Notes).
 * : Default is . Number of teeth (see also the information in Notes).
 * : Default is . Thickness of the uncut outer part of the gear.


 * : (read-only)
 * : (read-only) Inside diameter, measured at the addendum (the tip of the teeth).
 * : (read-only) Root diameter, measured at the foot of the teeth.
 * : (read-only) Working pitch diameter.
 * : (read-only) Outside diameter.
 * : (read-only) Pitch in the plane of rotation.


 * : Default is.
 * : Default is.


 * : Default is . With the helix angle β a helical gear is created – positive value → rotation direction right, negative value → rotation direction left (see also the information in Notes).
 * : Default is . creates a double helix gear (see also the information in Notes).
 * : Default is . If helix angle β is given and is, gear parameters are internally recomputed for the rotated gear.


 * : Default is . (see also the information in Notes).
 * : Default is . Generates a positive and negative profile shift (see also the information in Notes).


 * : Default is . generates a simplified display (without teeth and only a cylinder in pitch diameter).


 * : Default is . Backlash, also called lash or play, is the distance between the teeths at a gear pair.
 * : Default is . (see also the information in Notes).
 * : Default is . This value is used to change the tooth height.
 * : backlash decrease or  (default) backlash increase (see also the information in Notes).
