Description
Internal involute gears from left to right: Spur gearing, helical gearing, double helical gearing
Usage
- Switch to the FCGear Workbench.
- There are several ways to invoke the command:
- Press the Internal Involute Gear button in the toolbar.
- Select the Gear → Internal Involute Gear option from the menu.
- Change the gear parameter to the required conditions (see Properties).
Properties
An FCGear InternalInvoluteGear object is derived from a Part Feature object and inherits all its properties. It also has the following additional properties:
Data
accuracy
- Donnéesnumpoints (
Integer
): Default is6
. Change of the involute profile. Changing the value can lead to unexpected results.
base
- Donnéesheight (
Length
): Default is5,00 mm
. Value of the gear width. - Donnéesmodule (
Length
): Default is1,00 mm
. Module is the ratio of the reference diameter of the gear divided by the number of teeth (see Notes). - Donnéesteeth (
Integer
): Default is15
. Number of teeth (see Notes). - Donnéesthickness (
Length
): Default is5,00 mm
. Thickness of the uncut outer part of the gear.
computed
- Donnéesangular_backlash (
Angle
): (read-only) - Donnéesda (
Length
): (read-only) Inside diameter, measured at the addendum (the tip of the teeth). - Donnéesdf (
Length
): (read-only) Root diameter, measured at the foot of the teeth. - Donnéesdw (
Length
): (read-only) Working pitch diameter. - Donnéesoutside_diameter (
Length
): (read-only) Outside diameter. - Donnéestransverse_pitch (
Length
): (read-only) Pitch in the plane of rotation.
fillets
- Donnéeshead_fillet (
Float
): Default is0,00 mm
. - Donnéesroot_fillet (
Float
): Default is0,00 mm
.
helical
- Donnéesbeta (
Angle
): Default is0,00°
. With the helix angle β a helical gear is created – positive value → rotation direction right, negative value → rotation direction left (see Notes). - Donnéesdouble_helix (
Bool
): Default isfalse
.true
creates a double helix gear (see Notes). - Donnéesproperties_from_tool (
Bool
): Default isfalse
. If helix angle β is given and properties_from-tool istrue
, gear parameters are internally recomputed for the rotated gear.
involute
- Donnéespressure_angle (
Angle
): Default is20,00°
. (see Notes). - Donnéesshift (
Float
): Default is0,00
. Generates a positive and negative profile shift (see Notes).
precision
- Donnéessimple (
Bool
): Default isfalse
.true
generates a simplified display (without teeth and only a cylinder in pitch diameter).
tolerance
- Donnéesbacklash (
Length
): Default is0,00 mm
. Backlash, also called lash or play, is the distance between the teeths at a gear pair. - Donnéesclearance (
Float
): Default is0,25
. (see Notes). - Donnéeshead (
Float
): Default is-0,40 mm
. This value is used to change the tooth height. - Donnéesreversed_backlash (
Bool
):true
backlash decrease orfalse
(default) backlash increase (see Notes).
version
- Donnéesversion (
String
):
