The purpose of this study is to observe the generating mechanism and the reduction method of belt transverse vibration as a cause of timing belt noise. It is known that belt tension affects the transverse vibration. We have described the following two processes: First, the belt resonance frequency varies with the tension and the amplitude increases when the frequency equals the belt meshing frequency. Second, an excitation source exists in the belt tooth crest and bottom land, whose influence varies with the tension. Therefore, adjustment of pulley tooth height is confirmed to be effective for reducing the transverse vibration.

Having established the measurement technology to measure accessory belt behavior using laser displacement measurement methods, we were able to clarify the mechanism of the belt lateral vibration, which is one of the causes of a belt running off the pulley, by analyzing the correlation between the be
