FCGear InvoluteRack/pl

Description
Gear racks are used to convert a rotary motion into a linear motion or vice versa. The following examples show the different applications:
 * A rack with gear on at a retaining weir.
 * Various rack systems of rack-and-pinion railways.
 * Rack and pinion steering in a vehicle.
 * Rack and pinion winch as mechanical hoist (e.g. car jack).
 * Pneumatic rack and pinion drives used to control valves in pipeline transport.



Usage

 * 1) Switch to the [[Image:FCGear_workbench_icon.svg|22px]] FCGear Workbench.
 * 2) Invoke the command several way:
 * 3) * Press the FCGear_InvoluteRack.svg Create an Involute rack 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 in the transverse plane – not changeable, is calculated automatically (see also the information in ).


 * : If, than the total length of the rack is teeth * pitch, otherwise the rack starts with a tooth-flank.
 * : 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 )
 * : 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 ).
 * : If helix angle β is given and is enabled, gear parameters are internally recomputed for the rotated gear.
 * : generates a simplified display (without teeth).
 * : Number of teeth
 * : Height from the tooth root to the lower side of the rod.


 * : Default is 20 (see also the information in ).
