Abstract
The utility model provides a cantilever roller which comprises a roller shaft and a roller body arranged at one end of the roller shaft, and the other end of the roller shaft is arranged on a first bearing seat and a second bearing seat through two bearings respectively and is connected with a power machine. The cantilever roller is characterized in that the first bearing seat is a water cooling bearing seat, and heat dissipation pieces are arranged on the roller shaft between the water cooling bearing seat and the roller body. The heat dissipation pieces can be used for conveniently dissipating heat of the solid roller shaft, high strength of the roller shaft is guaranteed, the service life of conveying rollers is effectively prolonged, and through cooling of the water cooling bearing seat, the service life of the bearing and the bearing seat close to the high temperature area is effectively prolonged, production cost is lowered, labor is saved, and smooth and normal production is guaranteed.
Description
Technical field
The utility model relates to a kind of conveying roller, and the conveying roller of especially steel billet after heating being sent or being sent into from heating furnace belongs to steel rolling and produces conveying equipment technical field.
Background technology
Billet conveying roller table is requisite visual plant during steel rolling is produced, and the weight that should carry steel billet completes conveying again in hot environment.The conveying roller using at present mostly supports by being symmetricly set on bearing and the bearing block at conveying roller two ends, in the course of the work, bearing and bearing block near high-temperature area one side, very easily be subject to temperatures involved and cause lubricating oil to dryout, bearing block burns out, or cooling water pipe explosion, bearing locking etc., and bearing is changed in the regular stopping production of for this reason having to, both affect normal production, increased again maintenance cost and human resources.Someone has designed two bearings and bearing block concentrated setting at the opposite side away from high-temperature area for this reason, make conveying roller form overhang roll, though so solved the problem that bearing and bearing block are subject to temperatures involved, but bring conveying roller intensity and dispel the heat ineffectively, and affect the conveying roller problem in service life.Therefore, be necessary prior art to be improved.
Summary of the invention
The purpose of this utility model is to provide a kind of bearing and bearing block of can making away from high-temperature area, can improve conveying roller intensity again, improves radiating efficiency, extends the conveying roller overhang roll in service life.
The utility model completes by following technical proposal: a kind of overhang roll, comprise roll shaft, be located at the roller of roll shaft one end, the roll shaft other end is placed in respectively on first, second bearing block by two bearings, and be connected with engine, it is characterized in that clutch shaft bearing seat is made as water-cooling bearing block, and be provided with fin on the roll shaft between this water-cooling bearing block and roller, to dispel the heat by fin roll shaft, thereby improve conveying roller service life, by water-cooling bearing block, undertaken coolingly simultaneously, effectively extend bearing and bearing block service life, ensure normally and produce.
Described fin arranges multi-disc, is radially arranged on roll shaft surface, to dispel the heat by the quick roll shaft of fin.
Described water-cooling bearing block is provided with the cavity with entery and delivery port, and entery and delivery port is connected with cooling water source respectively by water pipe, to provide cooling water by water pipe and entery and delivery port in bearing block cavity.
Described roll shaft is solid shafting, to improve roll hardness.
The utlity model has following advantages and effect: adopt such scheme, can by fin, to solid roll shaft, dispel the heat easily, when guaranteeing that roll shaft has higher-strength, effectively improve the service life of conveying roller, pass through the cooling of water-cooling bearing block simultaneously, effectively extend the service life near high-temperature area one side bearing and bearing block, reduce production costs, save human resources, ensure normal carrying out smoothly of producing.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As Fig. 1, the overhang roll that the utility model provides, comprises roll shaft 3, is located at the roller 6 of roll shaft 3 left ends, roll shaft 3 right-hand members are placed in respectively on clutch shaft bearing seat and the second bearing block 2 by two bearings, and be connected with power motor 1, wherein, clutch shaft bearing seat is made as water-cooling bearing block 4, and be provided with fin 8 on the roll shaft 3 between this water-cooling bearing block 4 and roller 6, this fin 8 arranges multi-disc, is radially arranged on roll shaft 3 surfaces, to dispel the heat by the quick roll shaft 3 of fin 8; Described water-cooling bearing block 4 is provided with the cavity 9 with entery and delivery port 5,10, and entery and delivery port 5,10 is connected with cooling water source respectively by water pipe, to provide cooling water by water pipe and entery and delivery port 5,10 in water-cooling bearing block 4 cavitys 9; Described roll shaft 3 is solid shafting.
Claims (4)
1. an overhang roll, comprise roll shaft, be located at the roller of roll shaft one end, the roll shaft other end is placed in respectively on first, second bearing block by two bearings, and be connected with engine, it is characterized in that clutch shaft bearing seat is made as water-cooling bearing block, and be provided with fin on the roll shaft between this water-cooling bearing block and roller.
2. overhang roll according to claim 1, is characterized in that described fin arranges multi-disc, is radially arranged on roll shaft surface.
3. overhang roll according to claim 1, is characterized in that described water-cooling bearing block is provided with the cavity with entery and delivery port, and entery and delivery port is connected with cooling water source respectively by water pipe.
