초록
This manuscript aims to explore the lubrication behavior of ceramic bearings with polytetrafluoroethylene (PTFE) cagesunder low-temperature conditions by studying the friction and contact characteristics between PTFE cages and rollingelements. Taking the 6206CE deep-groove ball bearing as an example, a contact model between rolling elements and cagesis established to analyze the mechanical characteristics of the contact between ceramic balls and cages. Friction and wearcharacteristic tests for the rolling element-cage pairs in full-ceramic ball bearings are carried out, with PTFE as the researchsubject, to explore the influence of silicon nitride balls with different surface roughness on the friction and wear behaviorof PTFE, and to establish the lubrication characteristic laws among components of silicon nitride full-ceramic ball bearingsunder low-temperature conditions. The research in this manuscript can provide a research foundation for the lubricationcharacteristics of full-ceramic ball bearings under low-temperature conditions and offer technical support for the applicationof full-ceramic ball bearings in low-temperature working conditions.
