Originální abstrakt
One of the most important parameters determining the performance and life of machine parts is a lubrication film thickness and its distribution. Current experimental and numerical studies are mostly connected with oil lubrication. However greases are used in more than 80 % of all rolling bearings where the starvation phenomenon occurs most frequently. The question is whether the results obtained from the laboratory scaled contact test device are transferable to real operating conditions of full scale bearings. The aim of this work is to compare these two approaches to measuring film thickness of different greases. The use of multiple contacts optical test rig based on thin film colorimetric interferometry for film thickness measurement has enables to obtain film thickness of starved contact and the film distribution. The experimental observation of full-scale model of bearing will help to understand better the behavior of real bearing.
