摘要： In machining a pocket (1) installing therein a rolling element, tools (7, 8) are prepared whose milling parts (5, 8a) have contours which coincide with the sectional configuration of the pocket resulting when the pocket has been machined along a retainer radial direction (Z), and the milling parts (5, 8a) of the tools (7, 8) are inserted into a prepared hole for the pocket which is provided in advance and are then translated in a retainer revolving direction (Y) and axial direction (X), respectively, for forming the pocket. Accordingly, it is possible to provide a retainer for rolling bearings that has high accuracy in machining pockets and which is suitable for an integral one-piece retainer.

摘要： A ball bearing unit for a turbocharger according to an embodiment includes: an outer ring, a first inner ring, a second inner ring, a first machined retainer and a second machined retainer. The outer ring has an inner peripheral surface provided with an outer ring raceway surface at one end side and an outer ring raceway surface at another end side. At least one of the first machined retainer and the second machined retainer includes a plurality of pockets that hold the plurality of balls in a rollable manner in a circumferential direction. Each of the pockets has a diameter of equal to or more than 1.03 times and equal to or less than 1.07 times of a diameter of the balls.

摘要： In a copper alloy machined cage for a thrust ball bearing, an inside surface of a pocket includes a cylindrical surface, a support surface which is continuous with the cylindrical surface and contacts a ball in an axial direction, and two protruding portions which are formed at an equal interval in a circumferential direction of the pocket, at a ball insertion side of the pocket which is opposite to the support surface in the axial direction and protrude from the cylindrical surface. The protruding portions prevent falling out of the ball from a ball insertion side opening of the pocket and are either elastically deformed or elastic-plastically deformed by the ball during insertion of the ball into the pocket.
