Investigation of Elastic Sliding in Mechanisms with a Flexible Link with a Friction Clutch

Abstract

This work is a continuation of the studies of the interaction of an elastically deformable belt with a pulley presented in the article. If in the previous work the interaction of a flexible belt (link) with a fixed pulley was considered, then in this work the interaction of a flexible link with the leading and driven pulleys of the mechanism at the beginning of movement and in steady state is considered. As a result of theoretical studies, an expression was obtained for the coefficient characterizing the phenomenon of elastic sliding in mechanisms with a flexible link with a friction clutch. The linear dependence of the elastic slip coefficient on the thrust coefficient, defined as the ratio of the resistance force to the movement to the double initial tension of the branches of the flexible link, is noted. An expression estimating the effect of the elastic slip phenomenon on the value of the gear ratio of the actual mechanism is obtained. The condition of motion transmission in mechanisms with a flexible link with a friction clutch is considered. It is shown that when a certain value of the thrust coefficient is exceeded, slipping occurs in the mechanism instead of elastic sliding.
