PACKING DEVICE OF FORMING ROLL BEARING

摘要

FIELD: metallurgy. ^ SUBSTANCE: invention refers to rolling equipment, particularly to packing devices of bearings of working rollers and can be implemented, for example in packing devices of bearing supports of machines and mechanisms. The packing device of the bearing of the forming roll consists of V-shaped circular collar installed in a cover. The collar consists of a case, and of a conic jaw with a bridge with at least two working edges interacting with a head arranged on a roll neck. Generatrix connecting working edges of the collar in a free state is positioned at angle of 5-15 to working surface of the head whereat vertex of angle is directed to devise axis. The working edges of the collar are interconnected with the bridge; ratio of this bridge rigidity to rigidity of the conic jaw is 1:3. ^ EFFECT: increased service life of device and raised efficiency. ^ 1 dwg
