The influence of profile angle on forces distribution on silent chain transmissions

Abstract

The aim of this paper is to define and to analyze the theoretical contact forces that appear in a sprocket - silent chain joint. The contact force between the links and the teeth flanks of the sprocket can be considered as a reaction to the axial force (tensioning force) transmitted throughout the pins. The centrifugal force is considered to be constant and the friction between the elements is not considered. This paper is presenting the steps to obtain the relationships for the forces from the sprocket-link contact depending on the tensioning force component between the links and the centrifugal force. These forces are computed in order to establish their distribution on links.
