Abstract
Abstract An assembly to effect adjustments to the end play, or preloading, of a bearing set. The adjusting assembly utilizes a threaded bearing cup body and a correspondingly threaded adjusting ring. The bearing cup body abuts the outer race of the bearing and the adjusting ring is threaded onto the bearing cup body and abuts a fixed or stationary housing surface. The adjusting ring is rotated to adjust bearing preload and provide proper spacing. The bearing cap is then placed to lock the bearing adjusting assembly in place.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
112 words
An adjusting assembly for selectively adjusting a preload on a bearing assembly, said adjusting assembly being adapted to be interposed between a bearing assembly and a retaining means for said bearing assembly, said adjusting assembly comprising: a bearing cup body having a first threaded portion and an engaging portion adapted to abut an outer race of said bearing assembly; an adjusting ring having a main body portion and a second threaded portion threadingly engaging said first threaded portion, said adjusting ring being adapted to be interposed between said bearing assembly and said retaining means such that rotation of said second ring means effects axial translation of said first and second ring means.
Claim 2
Dependent Claim
112 words
An adjusting assembly for selectively adjusting a preload on a bearing assembly, said adjusting assembly being adapted to be interposed between a bearing assembly and a retaining means for said bearing assembly, said adjusting assembly comprising: a bearing cup body having a first threaded portion and an engaging portion adapted to abut an outer race of said bearing assembly; an adjusting ring having a main body portion and a second threaded portion threadingly engaging said first threaded portion, said adjusting ring being adapted to be interposed between said bearing assembly and said retaining means such that rotation of said second ring means effects axial translation of said first and second ring means.
Claim 3
Dependent Claim
25 words
The adjusting assembly of claim 1 , wherein said bearing cup body is sized to fit within a bearing recess formed in a differential carrier.
Claim 4
Dependent Claim
27 words
The adjusting assembly of claim 2 , wherein said adjusting ring is interposed between said bearing cup body and a stationary wall formed on said differential carrier.
Claim 5
Dependent Claim
