A Study on Transmission Characteristics of Toothed Belt Drives : 5th Report, Relative Shifting between Belt and Pulley in Normal and Reverse Revolutions under a State of Initial Tension

Abstract

In toothed belt drives under a state of initial tension in the static region, the relative shifting between belt and pulley in the cases of normal and reverse revolutions of the pulley is theoretically and experimentally discussed in regard to the elastic deformation of the belt and the polygonal action of the pulley. From this study the following conclusions have been obtained. (1) The relative shifting has a period of one pitch of the pulley. (2) There is an ideal initial tension in which the relative shifting is minimal. (3) The calculated results of the relative shifting agreed with the experimental results.
