Device for the study of the friction coefficient in the bolt-chain link joint

Abstract

Abstract The friction which appears in chain drives has an importantinfluence on their dynamic behaviour, wear and lifetime. The most significant friction and also wear is given by the bolt and chain link joint; in most of the cases this led to changes of the chain geometry and failures. Due to this, the study of the friction in the chain joints is required, but also difficult because of some particularities, as bolt and chain link reduced dimension, the oscillate motion in joint, chain link load.The paper presents a device for the friction coefficient study in the chain link-bolt joint, according to the mentioned requirements. First, the device ensemble 3D model is presented; the geometrical and kinematical restrictions between the parts are also defined. Then, the finite element analysis on this model is realized and is achieved for different initial conditions. In the paper final part, the analysis results and conclusions are presented.
