The impact of the pre-tensioning on the load distribution of timing belt drives

Abstract

The paper presents a numerical analysis of time belt drive. The finite element method (FEM) is applied for calculation of elements in this paper, timing belt and belt pulley at different load ranges. The subject of the analysis in this paper is the impact of pre-tensioning on load distribution at timing belt drive. The impact analysis of the pretensioning of timing belt is conducted for real timing belt drive. The timing belt drive is exposed to different values of the force of the pre-tensioning, and the results of the analysis of the timing belt drive indicate the change of the stresses in the operating conditions of the transmitter, and where the critical points are. The software package Autodesk Inventor Professional is used in analysis.
