FCGear InvoluteRack/de

Beschreibung
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.



Anwendung

 * 1) Zum Arbeitsbereich [[Image:FCGear_workbench_icon.svg|16px]] FCGear wechseln.
 * 2) Es gibt mehrere Möglichkeiten den Befehl aufzurufen:
 * 3) * Die Schaltfläche drücken.
 * 4) * Den Menüeintrag auswählen.
 * 5) Die Einstellungen den geforderten Randbedingungen entsprechend ändern (siehe ).

Daten

 * : Positionierung, bestimmt Ort und Ausrichtung eines Objekts im Raum.
 * : Editierbare Bezeichnung eines Objekts in der Baumansicht.


 * : 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.


 * : Voreingestellt ist 20° (siehe auch die Informationen unter ).

Hinweise

 * : The value is the result of multiplication of . This means for the standard involute rack of FCGear: 15 * 3,14  is 47.12 mm. See also  further 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. The result of the multiplication is displayed in
 * : Only change the parameter, if sufficient knowledge of the gear geometry is available.
