    摘要： Provided is a retainer (7), including a pair of annular members (8, 8), the pair of annular members (8, 8) being coupled to each other so that semispherical bulging portions (9, 9) which are opposed to each other form pockets (11) configured to retain balls (6). The pockets (11) each include a ball-opposed surface (12) having a ball non-contact portion (14) that is recessed toward a side opposite to the ball side. The ball non-contact portion (14) is formed outside a predetermined region (A) of the ball-opposed surface (12), which includes an intersection (P) of a pitch circle (PCD) of the balls (6) and a straight line (L) extending in a radial direction through a central portion of the ball-opposed surface (12) in a circumferential direction, and has an end portion on a radially outer side which is opened in a radially outer surface (8a) of the annular member (8).

    摘要： A retainer provides torque reduction. The retainer is formed by two annular retaining plates each including semispherical swelling portions arranged at predetermined intervals along a circumferential direction. The semispherical swelling portions face each other and form pockets for retaining balls. Each of the pockets has ball-facing surfaces each including a ball non-contact portion, and a contact area in each of the pockets with respect to each of the balls is reduced by from 15% to 30% by the ball non-contact portion. Each of the seal members serves as a contact seal having a seal lip portion coming into contact with another of raceway, and a material of at least a distal end of the seal lip portion includes a high-abrasion material which is prone to abrasion.

    摘要： A bearing assembly for a transmission, which is capable of avoiding an ingress of foreign matter, reducing seal torque and reducing shear resistance between a retainer and balls, includes a recessed portion in an inner face of a pocket of the retainer, in which the surface area of contact with a ball is smaller than the surface area of contact when no recessed portion is provided. A sealing member is a contact seal and material of a tip portion of a sealing lip region is highly wearable material which, when the bearing assembly is rotated, wears to define a non-contact or the like. A grease contains a base oil and a thickening agent and the base oil is a mineral oil alone or a mixed oil of mineral oil and poly-α-olefin oil and has base oil kinetic viscosity not higher than 100 mm2/s at 40° C.

    摘要： A ball bearing is described, which comprises an outer ring having on its inner periphery an outer raceway, an inner ring having on its outer periphery an inner raceway, plural balls rotatably disposed between the outer raceway and the inner raceway, a cage holding the plural balls in a freely rotatable manner, and a grease packed in a space between the outer raceway and the inner raceway, wherein the inner peripheral surface of each pocket of the cage contains a spherical part consisting of a spherical concave surface whose radius of curvature is slightly larger than that of each ball and a curved part which has the radius of curvature being larger than that of the spherical part and is smoothly continuous from the end of the spherical part toward the end thereof on the opening side of the pocket.

    摘要： The present invention is intended to provide a pressed retainer which can meet requirements for operation at high temperature and high speed, can sufficiently retain lubricant, does not allow ceramic balls, if used, to cut away track surfaces and is superior in wear resistance, and also intended to provide a ball bearing comprising the pressed retainer.In order to solve problems, in the pressed retainer, wherein two ring-shaped retainer plates, having ball retaining portions and flat portions at predetermined intervals in the circumferential direction thereof, are combined to face with each other so as to form pockets for accommodating balls, a first spherical concave portion and a second spherical concave portion having a curvature radius smaller than that of the first spherical concave portion are formed at the ball retaining portions, and a nitrided layer is formed on the surfaces of the ring-shaped retainer plates. The ball bearing of the present invention uses the pressed retainer and ceramic balls.

    摘要： A split ring antifriction bearing retainer assembled from two mating annular split rings. Each split ring has a plurality of ball pockets. When the two split rings are assembled, the ball pockets of one split ring are aligned with the ball pockets of the other split ring. The ends of one split ring are angularly offset from the ends of the other split ring.

    摘要： A separator or cage for ball bearings has a plurality of pockets. Each pocket has an internal pocket surface toward the ball. At each half of the pitch circle of the pocket around the ball there are two approximately cylindrical first surface sections which are spaced nearer to the ball, a respective spherically curved second pocket surface section which extends over the respective pole of the ball and which has a diameter smaller than the ball, and a respective third pocket surface section which extends over the equator of the ball at each circumferential end of the pocket and which has a larger diameter than the ball. The pocket surface provides good lubrication support for the ball to minimize rubbing of the ball against the separator pocket surface.
