Abstract

The utility model relates to a kind of rubber roll, comprises bearing, bearing outer ring, is wrapped in rubber layer on the periphery of bearing outer ring with one heart.The utility model rubber layer is directly bonded in bearing outer ring surface, after omitting iron core or aluminium core, conservation, reduce costs, the corresponding increase of specification of bearing, the bearing capacity of bearing strengthens, and the concentricity of rubber roll is controlled within 15, improve work efficiency, extend the working life of bearing.

Description

A kind of rubber roll

Technical field

The utility model relates to a kind of rubber roll.

Background technique

Current roller mainly comprises bearing, iron core or aluminium core, polyurethane layer or rubber layer, and iron core or aluminium core retainer plate are contained in outside bearing, and bearing outer ring and iron core or aluminium core transition fit, iron core or aluminium core are wrapped with polyurethane layer or rubber layer.In machine operation procedure, bearing and iron core can expanded by heating, produce relative sliding friction, iron core or aluminium core with bearing contact surfaces serious wear, cause iron core or the excesssive gap between aluminium core and bearing, roller galloping, and cannot normally use.The utility model utilizes the scalability of rubber and good elasticity to be embedded in lasso, has good firm performance.

Model utility content

The technical problems to be solved in the utility model is: in order to solve the problem of bearing and iron core or aluminium core contact surface abrasion, the utility model provides a kind of rubber roll.

The utility model solves the technological scheme that its technical problem adopts:

A kind of rubber roll, be made up of bearing 1, bearing outer ring 2, the with one heart rubber layer 3 be wrapped on the periphery of bearing outer ring, rubber layer 3 is connected on the periphery of bearing outer ring 2 by bonding mode.

Described a kind of rubber roll, bearing 1 be embedded in be wrapped in rubber layer 3 with one heart bearing outer ring 2 inside, the concentricity of rubber roll is controlled within 15.

The beneficial effects of the utility model are: the utility model rubber layer is directly bonded in bearing outer ring surface, after omitting iron core or aluminium core, conservation, reduce costs, firmly functional, the corresponding increase of specification of bearing, the bearing capacity of bearing strengthens, the concentricity of rubber roll is controlled, within 15, improve work efficiency, extend the working life of bearing.

Accompanying drawing explanation

Fig. 1 is the schematic diagram of a kind of example structure of the utility model lattice rubber roll;

Fig. 2 is the another kind of example structure schematic diagram of the utility model rubber roll.

Embodiment

Fig. 1 is the structural representation of a kind of example structure of the utility model rubber roll, mainly a kind of a kind of rubber roll of large size specification, be made up of bearing 1, bearing outer ring 2, the with one heart rubber layer 3 be wrapped on the periphery of bearing outer ring, rubber layer 3 is connected on the periphery of bearing outer ring 2 by bonding mode.Bearing 1 be embedded in be wrapped in rubber layer 3 with one heart bearing outer ring 2 inside, the concentricity of rubber roll controlled within 15, the rubber roll of large size specification is made up of bearing, bearing outer ring, the with one heart rubber layer be wrapped on the periphery of bearing outer ring.Rubber layer is directly bonded in bearing outer ring surface, has good firm performance.

Fig. 2 is the another kind of example structure schematic diagram of this use new type rubber roller, relate generally to a kind of structural representation of small gauge rubber roll, the rubber roll of small gauge is made up of bearing, bearing outer ring, the with one heart rubber layer be wrapped on the periphery of bearing outer ring.Rubber layer is directly bonded in bearing outer ring surface, has good firm performance.

Claims
