Study on the Test Method for High Temperature and Heavy Loaded Grease Bearing Life

Abstract

Temperature, load and rotate speed are the main factors which influence grease bearing life are presented by means of study on failure mechanism of grease. According to the test demands of high temperature and heavy loaded grease bearing life, test temperature, load and rotate speed of grease bearing life test are analyzed and discussed, presented that different greases should apply different test temperature. In addition, the filling amount of grease and test running mode of the grease bearing life test are discussed.

Design of a high-temperature grease by BP neural network and its preparation and high-temperature performance studies

“…In the fields of aerospace and metal forming, the bearings of some equipment are operated in a high-temperature environment of 200°C–300°C; thus, high-temperature greases are of great significance to the stable and long-lasting operation of equipment (Xu et al , 2012; Zheleznyi et al , 2007). To obtain new or better high-temperature greases, researchers had attempted to find new lubricating bases and thickeners or explore the influence of additives on the high-temperature performance of greases in recent years.…”
