Analysis and Amendment on the Dynamic Deviation of the Belt-type (or Chain-type) CVT

The deviation of the symmetric axis of the belt (or chain) to the vertical plane of the transmission shaft can occurs in the process of speed change of belt CVT or chain CVT. It can lead to the reducing of transmission service life, so far as to become invalid. In this paper, a quantitative analysis on the deviation has been made, and a design method of correct generatrix of the cone disc and an example are given.
