Abstract
Abstract A multiple-row tapered rolling bearing in an O-arrangement has an outer ring, a pair of abutting inner rings, and tapered rolling bodies arranged therebetween. The inner rings are axially secured together by a clamping ring which form-locks with annular grooves formed in the inner rings. A bore is provided in the outer ring which is adopted to allow a separating tool to be passed therethrough. The separating tool has a cutting edge which is impressed on the clamping ring during relative rotation of the outer and inner rings, thereby severing the clamping ring for disassembling the bearing.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
102 words
In a multiple-row tapered rolling bearing comprising an outer ring, first and second pluralities of rolling bodies, and a pair of inner rings axially connected by a clamping ring interlocked with respective grooves formed in said inner rings, said inner rings having side surfaces in abutting relation, the improvement wherein a through-hole is provided in said outer ring radially aligned with said clamping ring, said through-hole being formed to enable passage of a tool therethrough to engage said clamping ring during rotation of said clamping ring relative to said outer ring and thereby sever said clamping ring along a circumferential line thereof.
Claim 2
Dependent Claim
102 words
In a multiple-row tapered rolling bearing comprising an outer ring, first and second pluralities of rolling bodies, and a pair of inner rings axially connected by a clamping ring interlocked with respective grooves formed in said inner rings, said inner rings having side surfaces in abutting relation, the improvement wherein a through-hole is provided in said outer ring radially aligned with said clamping ring, said through-hole being formed to enable passage of a tool therethrough to engage said clamping ring during rotation of said clamping ring relative to said outer ring and thereby sever said clamping ring along a circumferential line thereof.
Claim 3
Dependent Claim
19 words
The multiple-row tapered rolling bearing of claim 1, wherein said clamping ring has a circular separation line formed therein.
Claim 4
Dependent Claim
16 words
The multiple-row tapered rolling bearing of claim 1, wherein said clamping ring is made of plastic.
Claim 5
Dependent Claim
28 words
The multiple-row tapered rolling bearing of claim 1, wherein said through-hole is a bore disposed along a radial line extending from the axis of rotation of the bearing.
Claim 6
Dependent Claim
37 words
The multiple-row tapered rolling bearing of claim 1, wherein said through-hole is a bore lying in a radial plane, said bore not being disposed along a radial line extending from the axis of rotation of the bearing.
Claim 7
Dependent Claim
117 words
In a multiple-row tapered rolling bearing comprising an outer ring, first and second pluralities of rolling bodies, and a pair of inner rings axially connected by a clamping ring interlocked with respective grooves formed in said inner rings, said inner rings having side surfaces in abutting relation, the improvement wherein a through-hole is provided in said outer ring radially aligned with said clamping ring, an inner end of said through-hole opposing an outer circumferential surface of said clamping ring, said through-hole being formed to enable passage of a tool therethrough to engage said clamping ring during rotation of said clamping ring relative to said outer ring and thereby sever said clamping ring along a circumferential line thereof.
Claim 8
Dependent Claim
117 words
In a multiple-row tapered rolling bearing comprising an outer ring, first and second pluralities of rolling bodies, and a pair of inner rings axially connected by a clamping ring interlocked with respective grooves formed in said inner rings, said inner rings having side surfaces in abutting relation, the improvement wherein a through-hole is provided in said outer ring radially aligned with said clamping ring, an inner end of said through-hole opposing an outer circumferential surface of said clamping ring, said through-hole being formed to enable passage of a tool therethrough to engage said clamping ring during rotation of said clamping ring relative to said outer ring and thereby sever said clamping ring along a circumferential line thereof.
