Abstract
An annular shoulder on the radial bearing is contacted by the thrust bearing raceway radially inwardly from the inside periphery of the thrust bearing cage. Either the thrust race or the annular shoulder on the radial bearing, or both, may have an integral axial extension with the thrust race and the radial bearing interlocking radially inwardly from the inner periphery of the thrust bearing cage. The bearing is pressed in to the bore of the housing by pushing against the thrust race with the force against the thrust race being transmitted by way of the annular shoulder to the radial raceway. Thus, it is not necessary to push the bearing into the housing bore by pressing against the thrust rollers which often results in critical damage to the thrust race.
Claims8
A combined radial and thrust bearing comprising:
- an axially extending rolling member radial bearing race having an axially extending raceway and a substantially radially inwardly extending annular portion;
- a radially extending rolling member thrust bearing race, an axial extension integrally connected to the inner periphery of the thrust bearing race or the inner periphery of said annular portion, or both,;
- a thrust bearing cage with rolling members;
- said thrust bearing cage having a predetermined inner periphery;
- means for retaining the thrust bearing cage against excessive axial movement;
- and radial bearing rolling members, said thrust bearing race being separate from and having at least a portion thereof in interlocking contact with said radially inwardly extending portion radially inwardly of the inner periphery of the thrust bearing cage so that force may be applied against the radially inner portion of the radially extending thrust bearing race and against the annular portion of the radial bearing race to assemble the bearing in a housing.
