초록

In order to investigate the influence of polyether ether ketone (PEEK) and its composite cage on the dry friction characteristicsof silicon nitride all-ceramic ball bearings, this paper firstly conducted a theoretical analysis of silicon nitride deep groove ballbearings subjected to radial load under dry friction conditions, and then conducted dry friction tests and simulation studieson PEEK, CF30 and PVX cage silicon nitride full ceramic ball bearings. The test results show that the temperature rise ofCF30 and PVX cage bearings is higher than that of PEEK cage bearings; the relationship between the root mean square valueof vibration of PEEK, CF30 and PVX cage bearings is PEEK cage bearings > CF30 cage bearings > PVX cage bearings; thesimulation model has good accuracy; Surface morphology analysis of the PVX cage bearing after the test show that thetransfer film has the effect of wear reduction and lubrication on the bearing. The results of the study have positive significancefor the research of transfer film lubricated bearings and the selection of cage materials.
