Abstract
The utility model patent discloses a kind of polyurethane bilayer carrying roller, roller including middle roll shaft and periphery, also include bearing, the sealing structure for sealed bearings installed on the bearing block fixed by jump ring at roll shaft and roller two ends, bearing block, it is characterised in that：Described roller is double-layer structure, respectively internal layer roller and outer layer roller, and internal layer roller is carbon steel material, outer layer roller is polyurethane material, the carbon steel material roller of internal layer is used for the overall rigidity of backing drum, heavier load can be carried, the polyurethane material of outer layer is used to reduce friction, self-lubricating, wear-resisting.
Description
Technical field
The utility model patent is related to a kind of carrying roller, the polyurethane bilayer carrying roller that especially a kind of load-bearing is high, intensity is high.
Background technology
Carrying roller is one of critical piece on ribbon conveyer, and the effect of carrying roller is support belt, reduces running resistance,
And make the sag of conveyer belt no more than certain limit, to ensure conveyer belt even running.Carrying roller accounts for the 30%- of main screw lift
40%, because large number of, the quality of carrying roller directly influences normal operation and the running cost of conveyer, and carrying roller is described as defeated
Send " heart " of machine.Main load bearing element is bearing in carrying roller, and bearing quality directly affects carrying roller performance and life-span.Roller
Quality can also directly affect the service life of carrying roller, and the intensity of roller can influence use longevity of bearing block and bearing
Life, in the transport places of some high capacities, roller high pressure, it is high-revolving in the case of be easily deformed, damaged, intensity is not
It is enough.
Utility model content
For the problems of the prior art, the purpose of this utility model is to provide for a kind of polyurethane bilayer carrying roller, the support
Roller combination polyurethane material wearability, self-lubricating property, two-layer drum structure is arranged to by carrying roller, and not only wearability is good, the life-span
Long, greasy property is good, and possesses support performance higher, can be widely applied to major heavy haul transport places.
In order to achieve the above object, the technical solution of the utility model is：
A kind of polyurethane bilayer carrying roller, including middle roll shaft and the roller of periphery, also including roll shaft and roller two ends
By bearing, the sealing structure for sealed bearings installed on the bearing block of jump ring fixation, bearing block, it is characterised in that：Institute
The roller stated is double-layer structure, respectively internal layer roller and outer layer roller, and internal layer roller is carbon steel material, and outer layer roller is poly-
Urethane material.The carbon steel material roller of internal layer is used for the overall rigidity of backing drum, can carry heavier load, the polyurethane of outer layer
Material is used to reduce friction, self-lubricating, wear-resisting.
Further, described internal layer roller end is welded with anti-string steel ring, outer layer roller is stopped by anti-string steel ring, prevents
Only outer layer roller axial float during use.
Further, described sealing structure includes two groups, and respectively the first sealing group and the second sealing group are labyrinth
Formula sealing structure, wherein, the first sealing group includes being sealed on first time sealing and first, and the second sealing group includes second time sealing
With second on seal.
Further, it is sealed in the first time sealing for assembling and first between sealing, in second time sealing and second
Between, between the first sealing group and the second sealing group leave labyrinth cavity.
Further, lubricating oil is filled in described labyrinth cavity, the lubricating oil is butter.
Compared with prior art, the structure of the polyurethane bilayer carrying roller that the utility model is provided is unusual, the carrying roller
Roller is double-layer structure, while its crocking resistance and greasy property is ensured, improves the support strength of roller, can be carried
Compared with big load, long service life, and the carrying roller employ two groups of labyrinth seal structures simultaneously, and dual-seal improves close
Sealing property, eliminates sealing gasket, saves part, and extend the service life of carrying roller.
Brief description of the drawings
In order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art, below will be to embodiment
Or the accompanying drawing to be used needed for description of the prior art is briefly described, it should be apparent that, drawings in the following description are only
It is some embodiments of the present utility model, for those of ordinary skill in the art, is not paying the premise of creative work
Under, other accompanying drawings can also be obtained according to these accompanying drawings.
Accompanying drawing 1 is the structural representation of this polyurethane bilayer carrying roller.
Specific embodiment
The utility model is further described with reference to the accompanying drawings and examples.
As shown in figure 1, polyurethane bilayer carrying roller, including middle roll shaft 1 and the roller of periphery, also including the He of roll shaft 1
Bearing 3, the sealing knot for sealed bearings 3 installed on the bearing block 4 fixed by jump ring 11 at roller two ends, bearing block 4
Structure, roller is double-layer structure, respectively internal layer roller 21 and outer layer roller 22, and internal layer roller 21 is carbon steel material, outer layer roller
Cylinder 22 is polyurethane material, and the end of internal layer roller 21 is welded with anti-string steel ring 10；The carbon steel material roller of internal layer is used for support roller
The overall rigidity of cylinder, can carry heavier load, and the polyurethane material of outer layer is used to reduce friction, self-lubricating, wear-resisting, anti-string steel ring
For making outer layer roller be stopped by anti-string steel ring, outer layer roller axial float during use is prevented.
During work, external motive device drives belt to rotate, and then drives outer layer roller 22 and internal layer roller by frictional force
Cylinder 21 is rotated relative to roll shaft 1, and its attachment structure between rotating against is bearing 4, and bearing 4 is sealed by sealing structure, and
Sealing structure for bearing 3 includes two groups, and respectively the first sealing group and the second sealing group are labyrinth seal structure,
Wherein, the first sealing group includes sealing 6 in first time sealing 5 and first, and the second sealing group is included in second time sealing 7 and second
Sealing 8.Between sealing 8 in assemble first time sealing 5 and first between sealing 6, in second time sealing 7 and second, first
Labyrinth cavity is left between sealing group and the second sealing group, lubricating oil is filled in described labyrinth cavity, the lubricating oil is
Butter, not only increases sealing function, also improves lubrication, further increases the service life of carrying roller.
It is understood that above with respect to specific descriptions of the present utility model, be merely to illustrate the utility model and not
The technical scheme described by the utility model embodiment is limited to, it will be understood by those within the art that, still can be with
The utility model is modified or equivalent, to reach identical technique effect；As long as satisfaction uses needs, all in this reality
Within new protection domain.
