Chain Drives



The Chain Drives library offers the possibility of the realistic representation and analysis of (closed) chain drives including polygon effect based oscillations in planar systems. The modeling principles are very close to the Belt Drives library.
Typical fields of application are the analysis of timing chains, control chains or camshaft drive chains of vehicles, construction machines or tool machines. In any case, the model structures will be modular and distinct.

The basic model principles (functionality of connectors and connections) as well as coordinate system definitions are taken from the Planar Mechanics library.

In addition to this, models of the Chain Drives library uses special types of Belt and Chain Connection and Belt and Chain-Connectors for the transfer of specific chain properties in a system.

The following figures (especially figure 2) demonstrate the modeling principle with this library. Chain section elements (free strands) connect sprockets. The contacting chain parts at sprockets are represented by the sprocket elements.
A chain section model should be modelled always from K2 of the first sprocket to K1 of the following sprocket etc. for a positive chain motion direction. You will fin the model shown in figure 1 and 2 in your sample browser.
