Information
In this model an ideal gear connection is modelled. It is based on the paper [Linden2012] However, no gear elasticity is modelled.
The planar model of an external gear wheel is used to build complex gear models. There is a corresponding example of SpurGear.
Using different parts from the planar library, it is possible to build complex gear systems. However, especially since no elasticity is included, kinematic loops can lead to complications and should be handled with care.
This model is suitable for:
- Kinematic analysis of gear systems and gear-like systems.
- Modelling of multiple gear stage models with clutches.
