An FCGear TimingGearT object is derived from a Part Feature object and inherits all its properties. It also has the following additional properties:
Data
base
- Dataalpha (
Length): Default is40°. Angle of tooth flanks. - Dataheight (
Length): Default is5 mm. Extrusion height. - Datanum_teeth (
Integer): Default is15. Number of teeth. - Datapitch (
Length): Default is5 mm. Pitch of gear. - Datatooth_height (
Length): Default is5 mm. Radial height of tooth. - Datau (
Length): Default is5 mm. Radial distance from tooth-head to pitch circle.
fillets
- Datahead_fillet (
FloatConstraint): Default is0.4. A fillet for the tooth-head, radius = head_fillet x module. - Dataroot_fillet (
FloatConstraint): Default is0.4. A fillet for the tooth-root, radius = root_fillet x module.
tolerance
- Databacklash (
Length): Default is0 mm. The arc length on the pitch circle by which the tooth thickness is reduced.
Scripting
Use the power of Python to automate your gear modeling:
import FreeCAD as App
import FreeCADGui as Gui
import freecad.gears.commands
gear = freecad.gears.commands.CreateTimingGearT.create()
gear.num_teeth = 12
gear.height = 5
App.ActiveDocument.recompute()
Gui.SendMsgToActiveView("ViewFit")
