FCGear CycloidGear/de

Beschreibung
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.

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.

Hinweise

 * Cycloidal gears must always be specially matched to each other and can generally not be exchanged at will!
 * In a gear pair, both gears have the same values for and . See also the information in  below.
 * : At a gear pair, clearance is the distance between the tooth tip of the first gear and the tooth root of the second gear.
 * : To use the double helical gearing the helix angle β for the helical gearing must first be entered.
 * : Using ISO (International Organization for Standardization) guidelines, Module size is designated as the unit representing gear tooth-sizes. Module (m): m = 1 (p = 3.1416), m = 2 (p = 6.2832), m = 4 (p = 12.566). If you multiply Module by Pi, you can obtain Pitch (p). Pitch is the distance between corresponding points on adjacent teeth.
