In this paper, the jumping characteristics of the driving and the driven pulleys of synchronous belt drives of 2 pulley systems with the same tooth numbers are experimentally and analytically discussed. The jumping phenomena on both pulleys have been observed by a high speed video camera and they have been simulated by the finite element method. The jumping of synchronous belts occurs when the elongation at the free span of the belt is more than a certain value. The following parameters are considered in the expression stiffness of the belt cord, height of belt tooth, ratio of tight side and slack side tension, belt installation tension, wrapping angle of belt, diameter of pulley pitch circle and the bending stiffness of machine. Jumping usually occurs at the driven pulley, jumping occurs when the wrapping angle of the belt on the driving pulley is less than 90 degrees.
