Abstract
The utility model relates to a bearing type supporting roller for a steel belt conveyor, which is a substitute product of a bearing of the steel belt conveyor, and is composed of an outer sleeve, a shaft sleeve, rolling posts, spring clamping rings, an outer clamp spring, and glands, wherein, the shaft sleeve and the rolling posts are arranged in the outer sleeve; both sides of the outer sleeve are provided with the glands; the glands are fixed by the spring clamping rings; the outer surface of the shaft sleeve is respectively provided with the outer clamp spring; heat-resisting grease is arranged at the fitting space of inner wall of the outer sleeve, the rolling posts, and the outer surface of the shaft sleeve. The utility model has the advantages of reasonable design, toughness, long service life, and low cost, and has the advantages that the impact and the load are resisted, the breakage can be effectively prevented, the maintenance cost can be reduced, and the work efficiency of the steel belt conveyor can be increased.
Description
The utility model relates to a kind of carrying roller, particularly steel-band conveyer bearing-type carrying roller.
The N30.2 bearing that uses on the supporting steel-band conveyer of existing and hot-rolling mill is because it exposes to roll in steel tank uses; its load is big; run to the sprocket wheel position again when the wheel shaft use; in this dynamic environment; job failure easily takes place in overcoat in the bearing; as dyskinesia; phenomenon of rupture; cause this bearing rapid wear perishable; often to overhaul replacing; waste great amount of manpower, increased the service expenditure of equipment, the applicant finds; bearing in use; normally enclosed, be sleeved in it on axle, overcoat is enclosed in the casing or adopts pedestal cap to be protected; generally should not expose outside and use; it is reported that the hole of bearing inner sleeve is the unit bore system tolerance, and the bearing outside external diameter is the standard shaft system tolerance, outer being enclosed within of bearing should not be exposed and the outer sleeve that ceaselessly rubs on the mechanical equipment; it is rotated use, therefore must use carrying roller to replace bearing to finish this task.
The purpose of this utility model is, improves at the deficiencies in the prior art, proposes and design a kind of steel-band conveyer bearing-type carrying roller.
Technical solution of the present utility model is, adopt overcoat, axle sleeve, roller, axle sleeve is set in the overcoat, outside the overcoat internal axle sleeve, roller is housed, roller is evenly distributed along the axle sleeve surface, and running-fit is characterized in that: be embedded with outer jump ring on the sleeve outer surface outside roller two respectively each other, axle sleeve two ends, overcoat both sides are set with capping, and capping is fixing on the coat by spring collar.
In overcoat, roller and outer casing inner wall, in the adapted space of sleeve outer surface temperature-resistant grease is arranged.
The axial motion gap of overcoat, axle sleeve is 1 millimeter.
The mounting groove groove depth of spring collar is 2 millimeters on the coat.
The sleeve surface quenching hardness is HRC45-55 °.
Sleeve diameter is 30.2 ± 0.02 millimeters.
Advantage of the present utility model is, adopts carrying roller to replace bearing, changes quenching hardness and material, thereby improve toughness and anti-shock loading, prevent phenomenon of rupture effectively, reduced productive costs, change the moving gap of string, avoided the moving phenomenon of shaking greatly and seriously of string, adopt temperature-resistant grease, improved heatproof and lubricant effect, prolonged service life of the present utility model, thereby greatly reduce maintenance workload, improved the work efficiency of steel-band conveyer.
Accompanying drawing, structural representation of the present utility model.
Below with reference to the accompanying drawings, describe embodiment of the present utility model in detail.
As shown in drawings, the utility model is by overcoat 1, axle sleeve 5, roller 7, spring collar 2, capping 3, outer jump ring 4 is formed, axle sleeve 5 is contained in the middle of the overcoat 1, in overcoat 1, axle sleeve 5 is equipped with roller 7 in appearance, several rollers 7 are evenly arranged in the outside face of axle sleeve 5, roller 7 and overcoat 1 inwall, the outside face running-fit of axle sleeve 5, in overcoat 1, roller 7 and overcoat 1 inwall, anti-temperature and bentonite base fourth--3# grease 8 more than 200 ℃ is arranged in the adapted space of axle sleeve 5 outside faces, on axle sleeve 5 outside faces at roller 7 two respectively symmetry be inlaid with outer jump ring 4, capping 3 is installed in the cavity of overcoat 1 both sides, capping 3 is set on axle sleeve 5 two ends, and running-fit has tolerance clearance mutually, capping 3 is fixed in the both sides cavity on the overcoat 1 by spring collar 2,2 millimeters of the mounting groove groove depths of mounting spring collar 2 have lubrication hole 6 on the overcoat 1 on the axle sleeve 5, are interlinked to the outside in lubrication hole 6 and the axle sleeve 5.Axle sleeve 5 internal diameters are 30.2 ± 0.02 millimeters.The quenching hardness of axle sleeve 5 is HRC45-55 °, adopts 45# steel or 45Mn materials processing to make.Roller 7 adopts 60Mn, GCr materials processing to make, and quenching hardness is HRC50-60 °.Overcoat 1 is selected 45# steel processing and fabricating for use, and quenching hardness is HRC45-55 °.The axial motion clearance control of overcoat 1, axle sleeve 5 is at 1 millimeter.
Overcoat 1 does not adopt glossing, and only needs finish turning not quench, and is antirust with the nitrate solution processing again, can reduce the treating cost cost.
