FCGear CycloidGear/en

Description
Cycloidal gears are very sensitive to an inaccurate adjustment of the centre distance, which then leads to a change in the transmission ratio. For these reasons, cycloidal gears are hardly found in mechanical engineering but are only used in special cases such as in the watch industry, for roots type blowers or for the drive of gear racks.



Usage

 * 1) Switch to the [[Image:FCGear_workbench_icon.svg|22px]] FCGear Workbench.
 * 2) Invoke the command several way:
 * 3) * Press the FCGear_CycloideGear.svg Create a Cycloide gear button in the tool bar.
 * 4) * Using the.
 * 5) Change the gear parameter to the required conditions (see  below).

Data

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


 * : Default is 5,00. Rolling circle of hypocycloid (see also the information in ).
 * : Default is 5,00. Rolling circle of epicycloid (see also the information in ).


 * : Default is 0,00. Backlash, also called lash or play, is the distance between the teeths at a gear pair.
 * : With the helix angle β a helical gear is created (positive value → rotation direction right, negative value → rotation direction left).
 * : Default is 0,25 (see also the information in ).
 * : creates a double helix gear (see also the information in )
 * : Value of the gear width.
 * : Module is the ratio of the reference diameter of the gear divided by the number of teeth (see also the information in ).
 * : Default is 15, change of the involute profile. Changing the value can lead to unexpected results.
 * : Number of teeth.
