介绍了聚四氟乙烯保持架的制造工艺 ,如填料的选择、预成型压力的选择 ,烧结温度的选择等 ,并测试了保持架的摩擦磨损性能、力学性能等 ,试制改性聚四氟乙烯保持架已应用于超低温轴承。
The manufacturing process of PTFE cage was introduced, such as the choice of filler, the selection of pre-forming pressure and the selection of sintering temperature. The friction and wear properties and mechanical properties of the cage were also tested. The modified polytetrafluoroethylene Cages have been used in cryogenic bearings.
