Investigation and calculation of the durability of sideflexing polymer chains

The article describes the results of fatigue tests with sideflexing polymer chains conducted on a dynamic testing machine and in testing conveyors. A new approach is suggested, that allows a calculatory estimation of the fatigue life of these chains. Finally, a calculation-software is presented, that has been developed based on the test results and the new equations.

Investigation of the loads and the rise of tensile forces in sideflexing sliderail chains

Depiction of an analysis of the loads and stress distribution in sideflexing chains revolving in 3D-conveyor systems. The article describes the results of measurements of chain tensile forces under different loads and in different conveyor sections. Consecutively new equations for the tension rise in sliding curves are developed and compared to the measurements.
