An experimental analysis of jumping phenomena of timing belts. Factors influencing the occurrence of jumping.

This report is an experimental analysis of jumping phenomena of timing belts widely using in office automation machines. It is found that belt and shaft stiffness, tension, temperature and so on exact influences on belt jumping, from the experiment. The facts suggest that it is most essential for prevention of jumping to make a belt more easily and more uniformly engage with pulleys by choosing a belt type and changing shaft stiffness and belt tension.
