| 제목 | Wear behavior in polymer/MoS2 composite cage for cryogenic bearing |
| 초록 | It was experimentally elucidate the mechanism of friction wear surface for the sliding and rolling contact movement in the cryogenic atmosphere. To evaluate the properties of the solid lubricating cage, we should minimize the frictional wear of the contact surface at a low temperature conditions. Investigations of wear resistance of polymers with additives, using the cryogenic apparatus has been carried out. Normal load, rotating speed and liquid nitrogen flow rate were considered variables in the cryogenic wear tests. The friction and the wear mechanisms are briefly reviewed. Various polymeric materials containing solid lubricants such as silver and lead were investigated. Cage center-of-mass orbits for cryogenic ball bearing with different solid lubricant are demonstrated. In the case of MoS2 containing composite cage, particular circular orbit is observed. Among the tested materials, the composites PTFE with additive MoS2 have shown good friction coefficient and low vibration. |
