A method and device for fitting an angular contact roller bearing, including an inner bearing ring having an inner race arranged on the outer peripheral surface of the inner bearing ring and inclined with respect to the axis of rotation of the bearing, and a rim delimiting said race at the smallest diameter thereof, an outer bearing ring having an outer race arranged on the inner peripheral surface of the outer bearing ring and inclined with respect to the axis of rotation of the bearing, and a rim delimiting said race at the greatest diameter thereof, and also including a plurality of roller bearing elements arranged between the bearing rings and roll on the races and are held at uniform distances from one another in the circumferential direction by a bearing cage. The outer peripheral surface of the inner bearing ring and the inner peripheral surface of the outer bearing ring are in each case cylindrical and extend outside the races at least in some sections coaxially with respect to the axis of rotation of the bearing, and the races of both bearing rings are in each case integrated conically into the cylindrical peripheral surfaces, such that the rims which are produced and in each case delimit the races on one side are in each case formed in one piece with the bearing rings. The fitting of the angular contact roller bearing takes place according to an eccentric pivot fitting method the deep groove ball bearing eccentric fitting method.

Method and device for fitting an angular contact roller bearing

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.

Method and device for assembly of an angular contact roller bearing

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.

Method and device for producing an angular contact roller bearing

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.

Angular contact roller bearing and method and device for the assembly thereof

The disclosure relates to a method for producing an angular contact roller bearing with unilaterally delimiting rims. The disclosure also relates to multiple variants of a device for assembling the angular contact roller bearing. The method may include conically forming an inner raceway into a cylindrical section of an outer shell surface of an inner bearing ring such that the inner raceway is inclined relative to the bearing axis of rotation (AL) and is delimited at one end by a rim, conically forming an outer raceway into a cylindrical section of an inner shell surface of an outer bearing ring such that the outer raceway is inclined relative to the bearing axis of rotation (AL) and is delimited at one end by a rim, and 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.

Angular contact roller bearings are disclosed. The bearing may include an inner bearing ring with an inner raceway, which is arranged on the outer shell surface of said inner bearing ring so as to be oblique with respect to the bearing axis of rotation (AL), and comprising a rim which delimits said raceway at its smallest diameter. An outer bearing ring has an outer raceway, which is arranged on the inner shell surface of said outer bearing ring likewise so as to be oblique with respect to the bearing axis of rotation (AL), and a rim which delimits said raceway at its greatest diameter. A multiplicity of roller-type rolling bodies are arranged between the bearing rings and roll on the raceways of said bearing rings and are held with uniform spacings to one another in a circumferential direction by means of 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, at least in the region of the raceways, of planar form so as to run in opposite directions obliquely with respect to the bearing axis of rotation (AL). The raceways of the two bearing rings are each formed in conical fashion into said shell surfaces and the rims which are thus formed and which delimit the raceways in each case on one side are thus each formed integrally with the bearing rings.

A cage segment of a rolling bearing, which cage segment has two side plates and two webs which are fixedly connected to one another, wherein the webs extend parallel to the axis of rotation of the rolling bodies of the rolling bearing, and in which cage segment the side plates and the webs form a pocket for receiving a rolling body. In order to be able to produce and assemble a cage segment of said type in an inexpensive manner, and in order to be able to ensure operation without jamming in an associated rolling bearing, it is provided that the two side plates on both sides of the pocket extend in a circumferential direction of the rolling bearing to such an extent that the side plates together with in each case one of the two webs form in each case one half-pocket for receiving a directly adjacent rolling body.
