摘要:
A solid film (5) of a fluorine-containing polyurethane polymer is formed on at least one of the constituent elements (inner and outer races (1 and 2), rolling member (3) and retainer (4)) of a rolling-contact bearing (A). The molecules of the solid film (5) of the fluorine-containing polyurethane polymer have urethane bonds, and form a three-dimensional reticular structure. Therefore, the film is unlikely to separate, peel off or wear, the occurrence of the dust can be restricted, and lubrication property can be improved.
摘要:
A surface-coated rubber or plastic sliding member having a coating with excellent durability and high slipperiness,wherein the coating comprises a solid lubricant such as molybdenum disulfide, a resin matrix and a reinforcement, said resin matrix comprising a fluoroolefin vinyl ether polymer resin and/or a fluoroolefin vinyl ether/vinyl ester copolymer resin.
摘要:
A method of making a novel bearing assembly for supporting a drive shaft, having a housing with a central bore in which is mounted a shell with a polygonal shaped opening which receives a plurality of circumferential spaced staves presenting a plurality of fiat planar surface that tangentially contact a drive shaft. The staves have a outer layer made of an ultra high molecular weight polyethylene material and an inner layer made of an elastomeric material. The outer layer is received by or may have a projection that is received by a corresponding recess in the shell which is made from a fiberglass material impregnated with an epoxy-resin.
