A Method to Determine the Static Load Distribution in a Chain Drive

Abstract

A model of how to calculate the load distribution for a chain drive is presented. In the model the complete standard geometry is used without any assumptions. The rollers which are in contact with the sprockets can move freely along the tooth flanks and their positions are given by force equilibrium. Since the positions of the rollers and thereby also the load distribution are dependent on the two connecting spans, these necessary tight and slack spans have been included in the model. The elastic deformation in the chain is included as well as the gravitational force.
