Method and device for producing an angular contact roller bearing

Abstract

The invention relates to a method for producing an angular contact roller bearing having limiting edges on one side. Furthermore, the invention also relates to two variants of a device for assemblingthe angular contact roller bearing. According to the invention, the following method steps are carried out: - incorporating an inner raceway (4) into a cylindrical portion of an outer lateral surface(3) of an inner bearing ring (2) in a conical manner so that the inner raceway (4) is inclined relative to the bearing rotational axis (AL) and is limited by an edge (5) at one end, - incorporating anouter raceway (8) into a cylindrical portion of an inner lateral surface (7) of an outer bearing ring (6) in a conical manner so that the outer raceway (8) is inclined relative to the bearing rotational axis (AL) and is limited by an edge (9) at one end, - assembling the inner and outer bearing rings (2, 6) as well as a plurality of roller rolling bodies (10) that roll on their raceways (4, 8) according to an eccentric assembly method known per se as an assembly method for deep groove ball bearings.

Description

technical field [0001] The invention relates to a method for producing, in particular a single row, angular contact roller bearing and a device for carrying out the method. The indicated angular contact roller bearings can advantageously be used for supporting crankshafts in internal combustion engines of motor vehicles. Background technique [0002] The most commonly used bearing type for supporting crankshafts in internal combustion engines of motor vehicles is the single row deep groove ball bearing, since this single row deep groove ball bearing is characterized by a uniformly high radial and axial load carrying capacity and because Its low friction has the highest speed limit of all bearing types. This deep groove ball bearing is formed in a known manner from an outer bearing ring and an inner bearing ring as well as a plurality of bearing balls arranged between the bearing rings, the bearing balls being introduced into the inner side of the outer bearing ring and Rol...

AI Technical Summary

Problems solved by technology

[0006] In these angular contact roller bearings, although only one of the bearing rings is constructed in one piece with only one lateral rib, the proportion of cutting operations during the manufacture of the raceways and during the machining of the ribs and The overall costs for bearing production are thus also significantly lower than in the case of the aforementioned cylindrical roller bearings, however, in these angular contact roller bearings the ribs are respectively formed on the other bearing rings as separate rib spacers, The additional mounting of the rib on the bearing ring and the need to precisely manufacture the contact surfaces on the rib and the associated bearing ring have a negative impact on the production costs of the angular contact roller bearing

Furthermore, in these angular contact roller bearings there is the risk that the individual rib disks are not fastened sufficiently even to withstand high radial or axial load peaks, so that the flange disks lose their May come loose and eventually cause bearing failure
