Abstract
A sealing double-row cylindrical roller bearing for a straightener comprises a cylindrical roller bearing body and a sealing assembly, and the cylindrical roller bearing body is composed of an outer ring, two inner rings, double-row cylinder rollers and two outer flat stop rings. The sealing assembly is formed by combining a steel frame and chemigum seals. The sealing assembly is embedded in the outer flat stop rings through the chemigum seals and is in interference fit with the outer ring through the steel frame. According to the sealing double-row cylindrical roller bearing, the service life of the bearing is greatly prolonged, the situation that bearings are frequently replaced on a production line is reduced, the production efficiency is improved, the production cost is reduced, and the sealing double-row cylindrical roller bearing is suitable for fields where work conditions are severe.
Description
Technical field
The present invention relates to technical field of bearings, particularly relate to a kind of straightening machine sealed double-row roller bearing.
Background technique
Common straightening machine Biserial cylindrical roller bearing is due to field working conditions inclement condition, and be not with stuffing box bearing easily to intake easy-to-rust, bearing enters dust, lubricates bad, thus causes bearing life greatly to decline.Production line often changes bearing, causes manufacturing efficiency to reduce, and consuming cost increases.
Summary of the invention
The technical problem to be solved in the present invention is, provides one greatly to improve bearing working life, and reduce production line and often change bearing, manufacturing efficiency improves, and reduces cost of production, is applicable to the straightening machine sealed double-row roller bearing of the severe onsite application of working condition.
The technological scheme adopted is:
A kind of straightening machine sealed double-row roller bearing, comprises the roller bearing and black box that are made up of outer ring, two inner rings, double-row cylindrical roller and two outer loose ribs.Described black box is made up of Steel Skeleton and nitrile butadiene rubber seal combination, and black box is embedded on outer loose rib by nitrile butadiene rubber sealing, and by Steel Skeleton and outer ring interference fit.
The present invention improves bearing working life greatly, reduces production line and often changes bearing, improve manufacturing efficiency, decrease cost of production, be applicable to the onsite application that working condition is severe.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is black box partial enlarged drawing of the present invention.
Embodiment
A kind of straightening machine sealed double-row roller bearing, comprises the roller bearing and black box 2 that are made up of 1, two, outer ring inner ring 4, double-row cylindrical roller 3 and two outer loose ribs 5.Described black box 2 seals 7 combinations by Steel Skeleton 6 and nitrile butadiene rubber and forms, and black box 2 is embedded on outer loose rib 5 by nitrile butadiene rubber sealing 7, and by Steel Skeleton 6 and outer ring 1 interference fit, forms a kind of straightening machine sealed double-row roller bearing.Described nitrile butadiene rubber sealing adopts double-layer seal, and what sealing adopted is opposite sex sealing, and good sealing effect is not fragile.
Claims (1)
