Abstract
The jumping characteristics at the driven pulley of L type synchronous belt drives are experimentally and analytically discussed. The number of the driving and the driven pulley teeth is the same and the wrapping angle of the belt on both pulleys is radian. The jumping of synchronous belt occurs when the elongation of the free span of tight side belt is more than a certain value. In this paper, the experimental results of the belt winding condition on the pulleys are compared with FEM analysis "ABAQUS/Standard" is used for the simulation and analysis of the belt. The simulation of the FEM analysis of the wrapping angle of the belt on the driven pulley is almost the same with the experimental result. FEM analysis of the load distribution at just before jumping on the driven pulley compared with the experimental results.
