Abstract
Abstract A bearing assembly for a rotating part liable to be subjected to an axial load of variable magnitude and direction, the bearing comprising two coaxial bearing sets each consisting of balls, an inner race and an outer race, the latter being mounted to slide axially, the two sliding races being resiliently urged towards respective abutment means, and the sliding motion of one of the such rings, in opposition to the action of the resilient impulsion, being limited by a second abutment means to an extent equal to the internal axial clearance of the other bearing.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
152 words
A bearing assembly comprising first and second ball bearings arranged side by side to support a rotatable member liable to be subjected to an axial load of variable magnitude and direction, each bearing having a set of balls arranged to run between an inner race and an outer race and to define an internal axial play therebetween, one of the races of each bearings being mounted for slidable axial movement, thrust means resiliently urging said two slidable races in respective axial directions to take up said internal axial plays in opposite directions, a pair of abutment means each adapted to abut a corresponding slidable race for taking said axial load, and further abutment means for limiting movement of the slidable race of the first bearing in the direction opposite to the thrust of said thrust means to a distance substantially equal to the extent of internal axial play in the second bearing.
Claim 2
Dependent Claim
152 words
A bearing assembly comprising first and second ball bearings arranged side by side to support a rotatable member liable to be subjected to an axial load of variable magnitude and direction, each bearing having a set of balls arranged to run between an inner race and an outer race and to define an internal axial play therebetween, one of the races of each bearings being mounted for slidable axial movement, thrust means resiliently urging said two slidable races in respective axial directions to take up said internal axial plays in opposite directions, a pair of abutment means each adapted to abut a corresponding slidable race for taking said axial load, and further abutment means for limiting movement of the slidable race of the first bearing in the direction opposite to the thrust of said thrust means to a distance substantially equal to the extent of internal axial play in the second bearing.
Claim 3
Dependent Claim
72 words
A bearing assembly according to claim 1, in which the two ball bearings are identical, the thrust means comprises a prestressed resilient component urging the two slidable races apart, and the further abutment means comprises surfaces of said resilient component which are adapted to engage each other in order to limit compression of said resilient component to a distance substantially equal to the extent of internal axial play of the two bearings.
