Description

Les engrenages coniques ne sont pas utilisés aussi souvent que les autres types d'engrenages, en partie à cause du bruit qu'ils génèrent. Mais ils sont encore utilisés dans certains secteurs, tels que les emballages alimentaires et les aliments en conserve, les équipements de jardin et de pelouse, les machines telles que les perceuses et les broyeurs, les systèmes de compression pour le marché du gaz et du pétrole et les vannes de régulation de débit.

Spiral bevel gears have curved teeth to provide softer engagement and greater tooth to tooth contact compared to a straight bevel gear. This reduces the vibration and noise. They can be used at high speeds and are typically used in motorcycle and bicycle transmissions.

Usage

  1. Switch to the FCGear Workbench.
  2. Invoke the command several way:
  3. Change the gear parameter to the required conditions (see Properties → Data below).

Properties

Data

Base

  • DonnéesPlacement: Placement is the location and orientation of an object in space.
  • DonnéesLabel: User name of the object in the Tree view.

gear_parameter

  • Donnéesbeta: With the angle β a helical bevel gear is created (positive value → rotation direction right, negative value → rotation direction left).

gear_parameter

  • Donnéesbackslash: Default is 0,00. Backlash, also called lash or play, is the distance between the teeths at a gear pair.
  • Donnéesclearance: Default is 0,10 (see also the information in Note).
  • Donnéesheight: Value for the bevel gear width.
  • Donnéesm: Module is the ratio of the reference diameter of the gear divided by the number of teeth (see also the information in Note).
  • Donnéesnumpoints: Default is 6, change of the involute profile. Changing the value can lead to unexpected results.
  • Donnéesreset_origin: If value is True the bevel gears outer face (cone footprint) will match the XY-Plane (Z = 0).
  • Donnéesteeth: Number of teeth.

involute_parameter

  • Donnéespitch_angel: Angle of taper.
  • Donnéespressure_parameter: Default is 20 (see also the information in Note).

View

The parameter descriptions of the View tab will be found in Property editor, further below at Example of the properties of a PartDesign object.

Notes

  • clearance: At a gear pair, clearance is the distance between the tooth tip of the first gear and the tooth root of the second gear.
  • module: 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.
  • pressure_parameter: Only change the parameter, if sufficient knowledge of the gear geometry is available.
