Claims
- 1. A method of producing a metal split bearing ring, said method comprising:
- (a) forming a notch in one of the edge surfaces of said ring, said notch including at least a first portion having a V-shaped cross-section, wherein the axis bisecting the angle of the V is at an oblique direction with the axis of said ring;
- (b) heat treating said metal ring to harden said metal ring to a hardness H.sub.RC .gtoreq.50;
- (c) applying a wedge stress along said notch using a wedge type pressure-breaking means having a wedge angle, wherein the angle of the wedge of the breaking means is between 20.degree. and 60.degree. and is greater than the angle of the V-shaped cross-section of said notch, whereby said ring is split along said notch.
- 2. A method of producing a split metal bearing ring as set forth in claim 1 including forming said notch with a second portion in the edge surface of said ring, said second portion having a V-shaped cross-section, said first portion being formed in one of the legs of the V of the second portion.
- 3. A method of producing a split metal bearing ring, said method comprising:
- (a) forming a first notch in one of the edge surfaces of said ring, said notch including at least a first portion having a V-shaped cross-section, wherein the axis bisecting the angle of the V is at an oblique direction with the axis of said ring;
- (b) forming a second notch in the other edge surface of the ring, said second notch including at least a first portion having a V-shaped cross-section, wherein the axis bisecting the angle of the V is at second oblique direction with the axis of said ring and wherein the axis bisecting the V's of the first and second notches intersect at a point on the peripheral surface of the ring between the edges of said ring;
- (c) forming a crack stopping hole through the peripheral surfaces of said ring at the point where the axes of the V's intersect;
- (d) heat treating said ring;
- (e) applying a wedge stress along said notches using a wedge type pressure breaking means, wherein the angle of the wedge of the breaking means is greater than the angle of the V-shaped cross-section of said notches, whereby said ring is split along said notches stopping at said crack stopping hole.
- 4. A method of producing a split metal bearing as set forth in claim 3 including forming said first and second notches with a second portion in the edge surface of said ring, said second portion having a V-shaped cross-section, said first portion being formed in one of the legs of the V of the second portion.
