Description
Technical Field
The utility model relates to an burn burning furnace equipment field, concretely relates to grate bearing roller for in burning furnace.
Background
The grate carrier roller is used for a grate system for incineration treatment of solid wastes, is arranged in the primary air chamber and positioned below the grate supporting beam, is used as an important part for supporting a grate, and is integrally installed and disassembled. The existing grate carrier roller adopts two bearings to roll, and because the working environment of the carrier roller is large in dust, high in temperature and low in rotating speed, lubrication is difficult to guarantee and normal and reliable lubrication cannot be realized, so that the bearings are seriously abraded and easy to lock, the service cycle is short, the equipment failure rate is high, and the overhaul cost is high.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the above-mentioned prior art not enough, provide a fire grate bearing roller in simple structure, low cost are used for the incinerator, adopt the graphite powder lubrication, can effectively improve lubricated effect, reduce the inside wearing and tearing of bearing roller, long service life.
In order to realize the above purpose, the utility model discloses a technical scheme be: the grate carrier roller comprises a roller shaft 1, roller wheels 2 and a shaft sleeve 3, wherein the roller shaft 1 is sleeved with the shaft sleeve 3 in a rotatable mode, the shaft sleeve 3 is sleeved with the roller wheels 2 in a rotatable mode, through holes are evenly formed in the circumferential surface of the shaft sleeve 3, a graphite core 4 is embedded into the through holes, annular limiting grooves 8 are formed in the two ends, located on the shaft sleeve 3, of the roller shaft 1, and end covers 5 matched with the roller wheels 2 are sleeved on the limiting grooves 8.
Furthermore, a sealing ring 6 matched with the end cover 5 is sleeved in the limiting groove 8.
Further, the shaft sleeve 3 is a copper shaft sleeve.
Furthermore, the end part of the roller 2 and the end cover 5 are both provided with corresponding threaded holes 7 in an annular shape, and the threaded holes are matched with bolts in a threaded manner.
The utility model has the advantages that: 1. when the relative roller of running roller rotated, drive the axle sleeve and rotate, the graphite core is lubricated by the outer disc that the graphite powder formed the centre bore of running roller and roller by wearing and tearing, and the graphite powder is stable under high temperature environment, can effectively improve lubricated effect, reduces the inside wearing and tearing of bearing roller, long service life.
2. Due to the design of the sealing ring, dust in the air chamber is prevented from entering the gap in the carrier roller to influence the lubricating effect.
3. The end cover and the roller are fixed through the bolts, so that the roller can be disassembled and assembled, and the shaft sleeve can be replaced conveniently.

Detailed Description
In order to make the technical solution of the present invention better understood, the present invention is described in detail below with reference to the accompanying drawings, and the description of the present invention is only exemplary and explanatory, and should not be construed as limiting the scope of the present invention.
As shown in fig. 1-4, the structure of the present invention is: the grate carrier roller comprises a roller shaft 1, roller wheels 2 and a shaft sleeve 3, wherein the roller shaft 1 is sleeved with the shaft sleeve 3 in a rotatable mode, the shaft sleeve 3 is sleeved with the roller wheels 2 in a rotatable mode, through holes are evenly formed in the circumferential surface of the shaft sleeve 3, a graphite core 4 is embedded into the through holes, annular limiting grooves 8 are formed in the two ends, located on the shaft sleeve 3, of the roller shaft 1, and end covers 5 matched with the roller wheels 2 are sleeved on the limiting grooves 8.
Preferably, the limiting groove 8 is internally sleeved with a sealing ring 6 matched with the end cover 5.
Preferably, the shaft sleeve 3 is a copper shaft sleeve.
Preferably, the end part of the roller 2 and the end cover 5 are both provided with corresponding threaded holes 7 in an annular shape, and the threaded holes are matched with bolts in a threaded manner.
During the specific use, when the relative roller 1 of running roller 2 rotated, drive axle sleeve 3 and rotate, graphite core 4 was lubricated by wearing and tearing formation graphite powder to the centre bore of running roller 2 and the outer disc of roller 1, and the graphite powder is stable under high temperature environment state, can effectively improve lubricated effect, reduces the inside wearing and tearing of bearing roller, long service life.
