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

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.

A ball roller bearing, which has an outer and inner bearing ring with a groove-shaped raceways and ball rollers, which roll between the bearing rings in the raceways. The rollers are held at distances from each other in the circumferential direction by a bearing cage and which have a width that is dimensioned larger than the radial distance between the inside and the outside of the bearing rings. The raceways are divided into two segments by an axially centered annular groove such that a first ball roller rolls on two first diagonally opposed track segments and a second ball roller rolls on two second diagonally opposed track segments of the bearing rings. Both bearing rings are single-piece components, and the bearing cage is formed by two identical double prong-type cages acting independently of each other. The bearing is filled with the ball rollers by an axial tilt cam assembly method.

Ball roller bearing, in particular for absorbing combined radial and axial loads

A roller bearing which has an outer and inner ring and ball rollers arranged between the rings, which roll in two groove-shaped tracks in the outer and inner rings and are held at a uniform distance to one another by a window cage that has two lateral ribs bent around two circumferential flanged edges to the inner ring and interconnected by pocket bridges. The cage pockets of the cage ribs have a hole formed from a cross-sectional contour of a ball roller arranged longitudinally to the circumferential direction and from a free contour incorporated therein and arranged perpendicular to the circumferential direction. The free contour in each cage pocket is expanded to a rectangle and the flange edges of the ribs each have reduced material thickness compared to the other material thickness of the cage by a circumferential, line-shaped burnishing.

Ball roller bearing

A ball roller bearing which has an outer and inner bearing ring and ball rollers arranged between the rings, which roll in groove-shaped tracks in the rings and are held at a uniform distance to one another by a window cage. The cage has two lateral angle ribs, pocket bridges, which connect the ribs and cage pockets separated by the pocket bridges. The pockets have a cross-shaped hole formed from a contour perpendicular to the circumferential direction and a cross-sectional contour of a ball roller arranged longitudinally to the circumferential direction. The side edges are formed from the pocket bridges, which have radii of arch-shaped guide surfaces corresponding to the running surfaces of two ball rollers. The pocket bridges have additional material profiling between the side edges and on the guide surfaces for axial stiffening of the cage and damping bearing noise.

A ball roller bearing and to a method for the installation thereof. The ball roller bearing has an outer bearing race, and an inner bearing race, and a plurality of ball rollers, which are disposed between the bearing races and are held at equal distances to each other by a bearing cage. For this purpose, the ball rollers have a width of approximately 70% of the diameter of a spherical shape thereof, and roll with bearing surfaces thereof in two groove-shaped raceways, the depth of which is smaller than the distance between the outer and inner bearing race. The cage pockets of the bearing cage have a cross-sectional contour of a ball roller disposed in the longitudinal and transverse directions to the circumferential direction. The method for installation of the ball roller bearing is a cross/oblique pivot mount between the inner and outer bearing races and the ball rollers.
