Abstract
A kind of operation roll of mill bearing mounting structure, comprise bearing, roll body, be arranged on the spindle nose at roll body two ends, transition shoulder is provided with between roll body and bearing, described bearing is arranged on above spindle nose, sleeve is provided with between described spindle nose and bearing, being interference fit between sleeve interior surface and spindle nose outer surface, is interference fit between bearing inner race and sleeve.When there is the situation of bearing locking in operation roll of mill bearing mounting structure of the present utility model, due to the buffer action of sleeve, working roll spindle nose can not be burned, pedestal also can not damage, only sleeve need be changed, within 4 hours, just can complete, maintenance time shortens greatly, also reduces maintenance cost simultaneously.
Description
Technical field
The utility model belongs to the technical field of aluminum foil rolling equipment, more particularly relates to a kind of operation roll of mill bearing mounting structure.
Background technology
Working roll on aluminium sheet or aluminium foil mill is the primary artifact that responsible extruded aluminum plate makes it thinning, the two ends of this working roll are arranged in frame by bearing, working roll is due to the problem of working environment and working strength, a lot of situation can cause bearing damage and the phenomenon of bearing locking occurs, and when dismantling the bearing burnt, the pedestal of roller will damage, can not continue to use, roller is scrapped or is repaired roller tables, scraps a roller about 10,000 yuan, repairs and also takes 10 day time; Be all very large waste for time cost and fund cost, have much room for improvement and adjust.
Utility model content
For solving the problem, the utility model provides a kind of operation roll of mill bearing mounting structure.
The technical solution of the utility model is: a kind of operation roll of mill bearing mounting structure, comprise bearing, roll body, be arranged on the spindle nose at roll body two ends, transition shoulder is provided with between roll body and bearing, described bearing is arranged on above spindle nose, sleeve is provided with between described spindle nose and bearing, being interference fit between sleeve interior surface and spindle nose outer surface, is interference fit between bearing inner race and sleeve.
Be provided with radial flange inside described sleeve, this flange width is not more than the thickness of bearing inner race; Described bearing side is close to this flange and is installed.
Described flange is evenly equipped with several breach.
Technique effect of the present utility model:
When there is the situation of bearing locking in operation roll of mill bearing mounting structure of the present utility model, due to the buffer action of sleeve, working roll spindle nose can not be burned, pedestal also can not damage, only sleeve need be changed, within 4 hours, just can complete, maintenance time shortens greatly, also reduces maintenance cost simultaneously.
