Abstract

This work has developed a series o-f theoretical techniques to establish the stress behaviour within a -fabricated conveyor pulley. The distribution o-f the bending moments between the pulley and the through shaft are confirmed. The Ray1eigh-Ritz energy method is adapted to develop a theoretical technique to analyse any variable thickness disc which is represented by cubic spline -functions. This technique is verified on analysis of constant discs using a traditional well proven method. Extensive strain gauge experiments are used for further verification. The belt traction distribution between the belt and pulley is modelled. The analysis of the shell is developed using double Fourier series to represent the symmetrical and anti-symmetrical loading conditions produced by the belt traction. The variation in stress distribution absorbed by the shell for various belt wrap angles is illustrated. An account of the shell end effects is also developed. A complete strain gauged pulley assembly is subjected to a static belt pull, to verify theoretical predictions with respect to component stiffnesses and boundary conditions. A Finite Element Analysis is also presented as further comparison.
