Angular contact ball bearing with an out-of-round rim and method for assembling same

A method of assembling an angular contact ball bearing consisting of an inner race and an outer race, each race containing at least one ball track in which a ring of balls rolls, at least one ball track of one race being bounded by a high rim on one side and by a low rim on the opposite side, characterized in that the low rim (8,10,24,25,28,29,43,53) on one of the races (1,2,14,17,18, 35,46) has an out-of-round contour having a number of higher portions (11,30) and lower portions (12,31), the lower portion of the out-of-round contour (12,31) leading preferably steplessly into the lowest portion of the ball track (3,4,15, 16,19,20,39,49), the out-of-round contour being such that the enveloping contour of the higher portions (11,30) of the low rim (8,10,24,25,28,29,43,53) corresponds to the enveloping contour of the balls (5,21,22,33,44) disposed in the outer race (1,2,14,17,18,36,47) when one of the races (1,2,14,17,18,36,47) is subjected to elastic out-of-round deformation by the action of pressure comprising inserting balls (5,21,22,33,34) into the race (1,2,14,17,18,36) other than the one provided with the out-of-round low rim, subjecting one of the races (1,2,14,17,18,36) to elastic out-of-round deformation by the application of pressure until the enveloping contour of the balls (5,21,22,33) and that of the higher portions (11,30) of the out-of-round low rim (8,10,24,25,28,29,43) correspond to one another, and aligning the races (1,2,14,17,18,35,36) in relation to one another in respect to their angular position so that they can be introduced axially one inside the other whreupon they are inserted one inside the other, whereafter the pressure action is discontinued.

A method of assembling an angular contact ball bearing consisting of an inner race and an outer race, two rings of balls (44,45) to receive radial forces and unilateral axial forces, the said balls being received in one-part races (46,47) on a common reference diameter, one ball track (48) in the outer race (47) and the other ball track (49) in the inner race (46) each having a low rim at the outer end (50,51) of the races (46,47) remote from any axial force and a high rim (54,55) on their opposite sides while the other ball tracks (56,57) in the outer race and inner race are bounded by high rims (58,59) on both sides, characterized in that the low rim (53) on the inner rade (46) has an out-of-round contour having a number of higher portions and lower portions, the lower portions of the out-of-round contour leading preferably steplessly into the lowest portion of the ball track (49), the out-of-round contour being such that the enveloping contour of the higher portions of the low rim (53) corresponds to the enveloping contour of the balls (44) disposed in the outer race when one of the races is subjected to elastic out-of-round deformation by the action of pressure, comprising introducing the ring of balls (44,45) into the track (56,57) having the high rims (58,59) on both sides in each race (46,47), subjecting one of the races (46,47) to elastic out-of-round deformation by the action of pressure until the enveloping contour of the balls (44) facing the out-of-round rim (53) and that of the higher portions of the low out-of-round rim (53) correspond to one another, and aligning the races (46,47) in relation to one another in respect of their angular position so that they can be introduced axially one inside the other, whereupon they are inserted on inside the other whereafter the pressure action is discontinued.
