FCGear InvoluteGear/it

Description
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 (see also the information in ).
 * : Default is 0,25 (see also the information in ).
 * : creates a double helix gear (see also the information in )
 * : Default is 0,00. This value is used to change the tooth height.
 * : 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 6, change of the involute profile. Changing the value can lead to unexpected results.
 * : If helix angle β is given and is enabled, gear parameters are internally recomputed for the rotated gear.
 * : Default is 0,00, generates a positive and negative profile shift (see also the information in ).
 * : generates a simplified display (without teeth and only a cylinder in pitch diameter).
 * : Number of teeth (see also the information in )
 * : changes the profil of the tooth root (see also the information in ).


 * : Default is 20 (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.
 * : backlash decrease or  backlash increase (see also the information in ).
