A flexible bearing cage includes a base ring comprising a plurality of mount sections arranged along a circular path and a plurality of compressible fold sections. One of the compressible fold sections is located between each adjacent pair of the mount sections, and a finger projects axially from each of the plurality of mount sections. Each of the fingers has a partially spherical concave surface configured such that the finger projecting from a first mount section on one side of a first one of the compressible fold sections and the finger projecting from a second mount section on a second side of the first one of the compressible fold sections define a partially spherical cavity configured to receive and retain a respective rolling body.

A method and device for assembly of an angular contact roller bearing, including an inner bearing ring having an inner raceway arranged on the outer peripheral surface of the inner bearing ring, at an angle to the bearing rotation axis, and a rim delimiting said raceway at the smallest diameter thereof, an outer bearing ring having an outer raceway arranged on the inner peripheral surface of the outer bearing ring, also at an angle to the bearing rotation axis, and a rim delimiting the raceway at the largest diameter thereof, and a plurality of rolling element bodies, arranged between the bearing rings and rolling on the raceways thereof held at regular distances in the circumferential direction by a bearing cage. A tangent to the outer shell surface of the inner bearing ring and a tangent to the inner shell surface of the outer bearing ring are flat at least in the region of the raceways, and extend at inverse to the bearing rotation axis, and the raceways of both bearing rings are each conically formed in the peripheral surfaces such that the rims thus produced and delimiting each of the raceways on one side are consequently each integral with the bearing rings. The bearing is assembled according to an eccentric-pivot assembly method borrowed from the eccentric assembly method known for grooved ball bearings.

Methods for producing an angular contact roller bearing with unilaterally delimiting rims are disclosed, as well as devices for assembling the angular contact roller bearing. The method may include generating an outer shell surface on an inner bearing ring, which outer shell surface is inclined in a first inclination direction relative to the bearing axis of rotation (AL) in an axial direction, generating an inner shell surface on an outer bearing ring, which inner shell surface is inclined in a second inclination direction relative to the bearing axis of rotation (AL) in an axial direction, wherein the second inclination direction is oriented oppositely to the first inclination direction, conically forming an inner raceway into the outer shell surface of the inner bearing ring such that the inner raceway is inclined relative to the bearing axis of rotation (AL) and is delimited at precisely one end by a rim, conically forming an outer raceway into the inner shell surface of the outer bearing ring, such that the outer raceway is inclined relative to the bearing axis of rotation (AL) and is delimited at precisely one end by a rim, assembling the inner and outer bearing rings and a multiplicity of roller-type rolling bodies, which roll on the raceways of said bearing rings, in accordance with an eccentric assembly method known as an assembly method for deep-groove ball bearings.

One embodiment is a bearing carrier assembly including a circular shield having top and bottom surfaces; and a number of bearing separators integrated with the bottom surface of the shield, wherein each pair of bearing separators defines a receptacle for receiving and retaining a bearing therewithin and wherein the shield blocks the received bearings from debris and retains lubricant around the received bearings. Each of the bearing separators may include a spacer element for separating adjacent ones of the bearings. The bearing carrier assembly may be made up of a number of carrier sections that interconnect to form the bearing carrier assembly.

A rolling bearing is mounted on a gear shaft, which extends along an axis and carries a first and a second toothing axially separated from each other by a cylindrical portion of the gear shaft. Such a cylindrical portion has an outer diameter smaller than that of the first toothing. The bearing is provided with rolling bodies, a cage with seats engageable by the rolling bodies, and an outer ring defining an outer rolling path for the rolling bodies. During assembly, the cage is fitted around the first toothing and axially displaced towards the second toothing until it is arranged around the cylindrical portion. In this step, the tenons of the cage pass in the slots between the teeth of the first toothing. Subsequently, the rolling bodies are radially inserted in the respective seats so as to be arranged against the cylindrical portion.

Angular contact roller bearings include an inner bearing ring with an inner raceway, which is arranged on the outer shell surface of the inner bearing ring so as to be inclined with respect to the bearing axis of rotation. An outer bearing ring has an outer raceway, which is arranged on the inner shell surface of the outer bearing ring so as to be inclined with respect to the bearing axis of rotation. An integrally formed rim delimits each, and a multiplicity of roller-type rolling bodies are arranged between the bearing rings and roll on the raceways of the bearing rings and are held with uniform spacings to one another in a circumferential direction by a bearing cage.
