Abstract
This paper presents an analytical method by which dynamic characteristics are clarified in a toothed belt system. In the belt system, variable tension and initial static tension act on the belt to transmit variable torque. The analysis assumes that variable tension is smaller than initial tension, and that the action of the former does not affect deformation caused by the latter. The dynamics of a meshing belt appeared through two different but related types of characteristics. One is static deformation, and the other dynamic response. The model used for analyzing the meshing belt is determined from the deformation and response in one tooth of the meshing belt. A method for calculating the elemental constants of the model is also shown. Dynamic characteristics were calculated for a simple belt system by using the model mentioned above for the meshing part of the belt. In the experiments, deformation and response were measured during meshing with plural teeth, and frequency characteristics were measured for the simple system. The computed and experimental results agreed fairly well. It was clarified that the analytical method is suitable for deducing the dynamic characteristics of a toothed belt system.
