Abstract
A solid lubricating composition having resin material is disposed between an outer ring and an inner ring of a ball bearing. As the resin material contained in the solid lubricating composition, resin material having a property of being solidified when the resin material in a fluid state is irradiated with an ultraviolet beam is used.
Claims4
A rolling device comprising:
- a rolling element disposing chamber having raceway surfaces on an inner surface thereof;
- rolling elements disposed on the raceway surfaces;
- and
- a solid lubricating composition that is placed in the rolling element disposing chamber and includes lubricant and resin material,
- wherein the resin material has a property in which the resin material is solidified when the resin material in a fluid state is irradiated with at least one of an electron beam or an ultraviolet beam.
2 more elements
A method of manufacturing a rolling device comprising:
- placing a solid lubricating composition inside a non-sealed chamber in a state where rolling elements are placed therein and the non-sealed chamber is not sealer and in a state that the solid lubricating composition is not solidified, in which the solid lubricating composition includes lubricant and resin material which has a property in which the resin material is solidified when the resin material in a fluid state is irradiated with at least one of an electron beam or an ultraviolet beam;
- and
- solidifying the solid lubricating composition by irradiating the solid lubricating composition in the non-solidified state with at least one of the electron beam and the ultraviolet beam.
