FCGear BevelGear/en

Description
Partly because of the noise they generate, bevel gears are not used as often as other types of gear. But they are still used in certain sectors, such as food packaging and canned food, lawn and garden equipment, machines such as drills and mills, compression systems for the gas and oil market and flow control valves.

Spiral bevel gears have curved teeth to provide softer engagement and greater tooth to tooth contact compared to a straight bevel gear. This reduces the vibration and noise. They can be used at high speeds and are typically used in motorcycle and bicycle transmissions.



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 Properties).

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

Data

 * : Value for the bevel gear width.
 * : Module is the ratio of the reference diameter of the gear divided by the number of teeth (see Notes).
 * : If the value is, the center of the axis is at the center of the bottom of the gear (see Notes).
 * : Number of teeth.


 * : (read-only)
 * : (read-only) Working pitch diameter.


 * : With the angle β a helical bevel gear is created (positive value → rotation direction right, negative value → rotation direction left).


 * : Angle of taper.


 * : Default is 20° (see Notes).


 * : Default is 6, change of the involute profile. Changing the value can lead to unexpected results.


 * : Default is 0,00. Backlash, also called lash or play, is the distance between the teeths at a gear pair.
 * : Default is 0,10 (see Notes).
