Abstract: A carrier is supported by a case via a bearing. The bearing comprises an inner race, an outer race, a plurality of rollers, and a retainer. The inner race has a tapered outer peripheral surface, and is fixed to a carrier. The outer race has a tapered inner peripheral surface facing the outer peripheral surface of the inner race, and is fixed to the case. The plurality of rollers is disposed between the inner race and the outer race. An end part of the retainer having a larger diameter makes contact with the case via a first member. The larger diameter end part of the retainer makes contact with the case via a second member. By the retainer making contact with the case and the carrier via the first member and the second member, the retainer can reduce friction compared to when making direct contact with the case and the carrier.

Abstract: Solid components, i.e. components manufactured from a solid semifinished product by a cutting method, are often used as components in machines, plants, etc. An example of such a solid component is a solid cage for use in a rolling body-type bearing. The solid cage is intended to guide and space apart rolling bodies. Such solid cages are formed in an annular manner and have windows in which the rolling bodies are arranged. A manufacturing device 7 for manufacturing a solid component from a component blank by at least one cycloid machining step is proposed, wherein the component blank is in the form of an intermediate product and has a plurality of rough pockets 14, having a component rotating device 8a, having a chisel 10, wherein the chisel 10 has a tool cutting lip 9, having a tool rotating device 8b, having an infeed device 8c, having a control device for controlling the component rotating device 8a, the tool rotating device 8b and the infeed device 8c such that the tool cutting lip 9 of the chisel 10 is guided along a cycloid path relative to the component blank rotating about the component rotation axis in a component direction of rotation, in order to machine the rough pockets 14, wherein a radial vector ZR to the tool rotation axis W, which extends through the cutting edge of the tool cutting lip 9 of the chisel 10, divides the tool cutting lip 9 into a clearance angle portion FW and into a rake angle portion SW, wherein the clearance angle portion FW is configured to be at least twice the size of the rake angle portion SW.

Abstract: A tapered roller bearing includes: an outer ring; an inner ring; a plurality of tapered rollers; and a cage that holds the tapered rollers at equal intervals in the circumferential direction of the tapered roller bearing. A small-diameter-side inner periphery end portion of the cage is located at a position inward of an axially outer small end face of the inner ring in the axial direction of the tapered roller bearing. A small-diameter-side end face of the cage has an inwardly tilted face that is tilted inward in the axial direction from the inner periphery end portion from the radially inner side to the radially outer side.

Abstract: The invention relates to an angular contact roller bearing (1) comprising an inner bearing ring (2) that has, on its outer lateral surface (3), an inner raceway (4) which is inclined relative to the bearing rotational axis (A
L ) and an edge (5) which limits this raceway (4) at its smallest diameter, an outer bearing ring (6) that has, on its inner lateral surface (7), an outer raceway (8) which is inclined relative to the bearing rotational axis (A
L ) and an edge (9) which limits this raceway (8) at its largest diameter as well as a plurality of roller rolling bodies (10) which are provided between the bearing rings (2, 6) and roll on their raceways (4, 8), said roller rolling bodies being held at equal distances from each other in the circumferential direction by a bearing cage (11). This angular contact roller bearing (1) is, according to the invention, characterized in that at least portions of the outer lateral surface (3) of the inner bearing ring (2) and the inner lateral surface (7) of the outer bearing ring (6) are, outside of the raceways (4, 8), cylindrical extending coaxially to the bearing rotational axis (A
L ) and the raceways (4, 8) of both bearing rings (2, 6) are each incorporated into the lateral surfaces (3, 7) in a conical manner, and in that the edges (5, 9) created thereby and limiting the raceways (4, 8) at one end are, as a result, integral with the bearing rings (2, 6). Furthermore, the invention also relates to two variants of a method and a device for assembling the single-row angular contact roller bearing.-

Abstract: A guide piece (6) projects from an outside surface of a cage bar (5b) of a cage (5) so as to make sliding contact with a raceway surface (3a) of an outer ring (3). As the cage (5) rotates, the guiding piece (6) operates to guide the rotation of the cage (5) while removing an excess grease (G) on the raceway surface (3a) and transferring the excess grease (G) to axially opposite ends of the outer ring (3).

Abstract: The present invention provides a needle bearing including a cage that is shrinkable or extensible in a circumferential direction, which can prevent plastic deformation and ensure both of a sufficient strength for axial torsion and a sufficient deformation amount. In a drawn cup needle bearing 10, a cage 13 includes a plurality of elastic deformation portions 17 along a circumferential direction thereof, which are shrunk in the circumferential direction. The elastic deformation portions 17 are formed symmetrically with respect to an intermediate portion C in an axial direction of the cage.
