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).

Usage

 * 1) Switch to the [[Image:FCGear_workbench_icon.svg|22px]] FCGear Workbench.
 * 2) Invoke the command several way:
 * 3) * Press the FCGear_InvoluteGear.svg Create an Involute 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.


 * : Pitch diameter (not changeable, is calculated automatically).


 * : With the helix angle β a helical gear is created (positive value = rotation direction right, negative value = rotation direction left).
 * : The value is subtracted or added to the root diameter.
 * : True = creates double helix gear; False = in conjunction with the helix angle β a helix gear is generated (see also the information in )
 * : Value of * module = additional length of addendum diameter.
 * : Value for the gear width.
 * : The is the quotient of the pitch circle diameter and the number of teeth  (see also the information in ).
 * : Change of the involute profile.
 * : If helix angle β is given and is enabled, gear parameters are internally recomputed for the rotated gear.
 * : Change of the complete tooth profile.
 * : True = simplified display.
 * : Number of teeth (see also the information in )
 * : True = Change of the tooth profile within the root diameter (see also the information in ).


 * : For a standard gear, this pressure angle is fixed at 20° with backlash-free pairing of the teeth (see also the information in ).


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