Patent ID: 8063002

Claim:
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 sealed 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 non-solidified 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, wherein the rolling element is disposed between a raceway surface of an outer ring and a raceway surface of an inner ring, wherein the non-sealed chamber is defined by an inner periphery of the outer ring and an outer periphery of the inner ring, wherein the ultraviolet beam is irradiated from outside in an axial direction of the outer ring, wherein a timing for irradiating the ultraviolet beam is varied depending on a position of the solid lubricating composition in a radial direction of the outer ring, and wherein a region to be irradiated with the ultraviolet beam is gradually expanded from a position including a pitch circle of a ball bearing to inside and outside of the position in the radial direction, so that the solid lubricating composition is gradually solidified inward and outward in the radial direction from the position including the pitch circle of the ball bearing.
