Experimental and numerical transient thermal analysis of the idler bearing housing made of steel or polymer material

The research of the influence housing material on operation temperature idler bearing assembly is presented in this paper. Several radial loads and rotary speeds were applied to test bench determine transient field. results monitored recorded for whole period until reached stationary stage. FEM model was created where rolling elements replaced with especially designed artificial body, having shape irregular ring. It generates heat connects only those points inner outer ring which are operating conditions connected elements. experimental compared results. conclusion given suitability polymer purpose.
