Title

Belt Deformation in V-Belt Drives under Dynamic Loading - Maximum Strains in the Cord Layer of an Operating V-Belt Are Measured. a Comparison of Present Experimental Data and Theoretical Predictions Reveals Potentially Significant Differences

Abstract

Recent theoretical work permits a characterization of loads in the cord layer of operating V-belts. Experimental evidence corroborating theory has been limited. Such evidence has been collected and is presented in this paper. Given are empirical relationships describing how peak strains across and along the belt occurring during an operating cycle vary with preload, transmitted torque, pulley diameter and speed. Representative plots are included to illustrate the dependence of strains on position around pulleys in the drive system. Comparisons of theoretical results and data collected during this study reveal potentially significant differences. Reasons for these differences are hypothesized. High strain rates in operating V-belt drives and their influence on maximum stress are discussed, as are subsidiary matters including belt instrumentation and strain-signal transmission.
