Method of manufacturing bearing rings ruptured along an arrow-shaped partition line |
摘要 |
The present invention is a method for the manufacture of bearing rings ruptured along an arrow-shaped partition line for antifriction bearings or similar devices. According to the invention a radial bore is introduced through the middle of the ring transversely of the bearing axis, and in the opposite end faces are introduced V-shaped notches which are displaced in relation to the radial bore in a circumferential direction. The bearing ring is supported on one end and ruptured first on that end by a force directed against the opposite end. The ring is turned over and again ruptured similarly until an arrow-shaped partition line extends from the radial bore to the notches.
