摘要： A method of manufacturing a steel ball for a rolling bearing, said method comprising: a molding step of forming a steel wire cut at a predetermined length into a raw ball having a band portion by a pair of molding forms having respectively hemispherical concave portions and relief grooves in peripheries of said concave portions on their respective opposing faces, said band portion being formed on a surface of said raw ball along said relief grooves by compressing said steel wire by said molding forms in a state in which both ends of said steel wire are sandwiched between said concave portions; and a tumbler working step of removing said band portion from the surface of the raw ball by tumbling.

摘要： This invention provides a one-way clutch for switching between a locking state in which an inner wheel and an outer wheel rotate synchronously and a free state in which they rotate relative to each other. This one-way clutch includes a holding device having pockets for accommodating each of rollers rotatably in a circumferential direction provided at several positions on its circumference and coil springs which are accommodated in each of the pockets in a compressed state and for urging the rollers to a locking side by their expanding restoration force. In an intermediate range in an axial direction of the roller, each of the coil springs is in contact with a range over 1/2 a dimension in the axial direction of the roller. As a result, the urging force of the coil spring can be supplied to the roller at a good balance, so that the rollers become easy to rotate smoothly with a proper posture.

摘要： A ball bearing cage is formed with pockets (7) each having an inwardly curved spherical pocket face similar to a ball in shape. At least one of the pockets (7) has a protrusion (8) projecting inwardly thereof from one of inner and outer circumferential edge portions of the pocket face. A ball bearing comprises balls retained between inner and outer bearing rings and equispaced circumferentially thereof by a cage. The cage is formed with pockets each having an inwardly curved spherical pocket face similar to the ball in shape, at least one of the pockets having a protrusion projecting inwardly thereof from an edge portion of the face close to the fixed one of the rings.
