Abstract
Abstract The outer ball bearing races (16, 26) of two ball bearings (12, 14) are supported on each other through a cardan joint (42). Axial bias forces in opposite directions are exerted on the inner ball bearing races (18, 28) by screws (44, 50) through cardan joints (48, 54). When the ball bearings rotate the outer ball bearing races (16, 26) are aligned. By means of a curing bonding agent the outer ball bearing races (16, 26) are fixed in a bearing sleeve (10) and the inner ball bearing races (18, 28) are fixed to a shaft (36) when the ball bearings rotate.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
160 words
A method of compensating for tolerances in a rotary mounting having an axis of rotation and two ball bearings (12, 14) which are located in a bearing member (10) and have inner and outer ball bearing races (16, 26) each, the ball bearings being tensioned against each other, characterized by the method steps: a) supporting the ball bearing races (16, 26) of a first type on each other through an inner universally movable joint (42), the inner universally movable joint having PG,12 a pivot point located on the axis of rotation of the rotary mounting, b) exerting axial forces in opposite directions on the ball bearing races (18, 28) of a second type through outer universally movable joints (48, 54), the outer universally movable joints having pivot points located on the axis of rotation of the rotary mounting, c) fixing the ball bearing races (16, 26) of the first type in the bearing member (10), while such forces are exerted.
Claim 2
Independent Claim
160 words
A method of compensating for tolerances in a rotary mounting having an axis of rotation and two ball bearings (12, 14) which are located in a bearing member (10) and have inner and outer ball bearing races (16, 26) each, the ball bearings being tensioned against each other, characterized by the method steps: a) supporting the ball bearing races (16, 26) of a first type on each other through an inner universally movable joint (42), the inner universally movable joint having PG,12 a pivot point located on the axis of rotation of the rotary mounting, b) exerting axial forces in opposite directions on the ball bearing races (18, 28) of a second type through outer universally movable joints (48, 54), the outer universally movable joints having pivot points located on the axis of rotation of the rotary mounting, c) fixing the ball bearing races (16, 26) of the first type in the bearing member (10), while such forces are exerted.
Claim 3
Dependent Claim
40 words
The method as set forth in claim 1, characterized in that the ball bearing races of the first type are the outer ball bearing races and the ball bearing races of the second type are the inner ball bearing races.
Claim 4
Dependent Claim
30 words
The method as set forth in claim 1, characterized in that the supporting and the exerting of forces are effected through cardan joints as universally movable joints (42, 48, 54).
Claim 5
Dependent Claim
41 words
The method as set forth in claim 1 characterized in that the fixing step comprises introducing a bonding agent into a bonding slot (56, 58) between the bearing member (10) and the ball bearing races (16, 26) of the first type.
Claim 6
Dependent Claim
52 words
The method as set forth in claim 1, characterized in that the exerting step comprises exerting axial forces by screwing screws (44, 50) into end faces of a shaft (36) mounted in the ball bearings (12, 14), the screws having heads (46, 52) which engage the outer universally movable joints (48, 54).
Claim 7
Dependent Claim
36 words
The method as set forth in claim 1, characterized in that the fixing step further comprises rotating the inner and outer ball bearing races (16, 18; 26, 28) relative to each other during the fixing process.
Claim 8
Dependent Claim
28 words
The method as set forth in claim 1, further comprising removing the outer universally movable joints after the fixing of the ball bearing races of the first type.
