Influence of Belt Transmission Parameters on the Stiffness of the Elastic Elements of the Driven Pulley and Tensioning Roller

Abstract

The article presents the ways of wide use of belt drives with variable and gear ratios in the drive mechanisms of technological machines. The scheme and principle of operation of the belt drive with composite driven pulleys and a tension roller are given, the necessary variable driving modes of the driven pulley are allowed. Analytical methods for determining the stiffness of the elastic elements of the driven pulley and tensioning roller are given. Based on the analysis of the plotted dependencies, the recommended values of the parameters of the considered belt drive for technological machine drives are substantiated. Production experiments and test results of the 1-CCC (Cotton Cleaning Complex) machine with the recommended belt drive justified the system parameters.
