Abstract

The bearing provides an outer ring and an inner ring capable of rotating concentrically relative to one another. At least one of the inner and outer rings are split into a plurality of successive circumferential ring segments. Each pair of adjacent successive ring segments of the split-ring is secured together with at least one fixing plate. The fixing plate is disposed inside a first groove disposed on one of the ring segments and a second groove 38 disposed on the other ring segment. The fixing plate is set back or flush with at least the surface of each of the ring segments from which the first or second groove is formed.

First claim

The invention claimed is:

1. A bearing comprising:
an outer ring, and
an inner ring capable of rotating concentrically relative to one another, at least one of the inner and outer rings being split into a plurality of successive circumferential ring segments, wherein
adjacent successive circumferential ring segments of the plurality of successive circumferential ring segments are secured together with at least one fixing plate, the fixing plate being disposed inside a first groove provided on one of the ring segments and a second groove provided on the other ring segment, the fixing plate being set back or flush with at least the surface of each of the ring segments from which the first or second groove is formed.

2. The bearing according to claim 1 , wherein a plate circumferential outermost surface of the fixing plate is radially inward or flush with a ring circumferential outermost surface of the split-ring.

3. The bearing according to claim 1 , further comprising at least first and second alignment members extending through the fixing plate, the first alignment member protruding into a recess formed into the thickness of one of the ring segments, and the second alignment member protruding into a recess formed into the thickness of the other ring segment.

4. The bearing according to claim 3 , wherein the first and second alignment members are radially inward or flush with an outer surface of the fixing plate which is located on the side opposite to the first and second grooves of the ring segments.

5. The bearing according to claim 3 , wherein each of the first and second alignment members comprises a pin.

6. The bearing according to claim 1 , further comprising at least one first fixing screw and at least one second fixing screw extending through the fixing plate, the first fixing screw being engaged inside a threaded hole formed onto one of the ring segments, and the second fixing screw being engaged inside a threaded hole formed onto the other ring segment.

7. The bearing according to claim 6 , wherein screw heads of the first and second fixing screws are set back or flush with an outer surface of the fixing plate which is located on the side opposite to the first and second grooves of the ring segments.

8. The bearing according to claim 1 , wherein the first and second grooves are provided on the outer cylindrical surfaces of the ring segments delimiting at least partly the outer cylindrical surface of the split-ring, or are provided on the inner cylindrical surfaces of the ring segments delimiting at least partly the inner cylindrical bore of the split-ring.

9. The bearing according to claim 1 , wherein the first and second grooves are provided on frontal faces of the ring segments delimiting at least partly a frontal face of the split-ring.

10. The bearing according to claim 1 , wherein the fixing plate is made from steel.
