Abstract
A strip of metal is wrapped into a ring configuration such that ends of the strip are positioned in a predetermined relationship to each other. The ends of the strip are attached together by a temporary weld joining the two ends of the strip, thereby forming a temporary continuous ring. After heat treating the temporary continuous ring, the ring is separated at the temporary weld to provide a heat treated split bearing ring with a controlled clearance at the split.
Claims6
A method of manufacturing a split bearing ring, the method comprising:
- wrapping a strip of metal having first and second ends into a ring configuration such that the first and second ends of the strip are positioned in a predetermined relationship to each other;
- attaching the first and second ends of the strip together by at least one temporary weld joining the two ends of the strip, thereby forming a temporary continuous ring with the first and second ends having a predetermined clearance therebetween;
- heat treating the temporary continuous ring;
- and
- detaching the first and second ends of the temporary continuous ring at the at least one temporary weld to provide a heat treated split bearing ring with a controlled clearance at a split of the split ring equal to the predetermined clearance.
