According to the roller, the pressing covers are provided with the rotating cover grease cups communicated with the bearings, regular oiling can be conducted under the circumstance that the roller body operates, and normal maintaining work of equipment is guaranteed; the rubber frame oil seals are arranged between the bearing covers and the rotary shaft, the roller is effectively sealed, the problem that ash enters the bearing blocks to damage the bearings is solved, operation reliability of the roller is improved, and service life of the roller is prolonged.
Description
Technical field
The utility model relates to a kind of belt conveyer, specifically a kind of belt conveyer cylinder.
Background technology
Belt conveyer claims again band conveyor, load-transfer device moves according to frictional transmission principle, be applicable to carry bulk density to be less than 1.67 tons/cubic meter, be easy to draw low chiseling property of mill material and the bagged material of the powdery got, granular, little bulk, as desirable load transfer devices of industry such as coal, ore, coke, sand, slag, grain Deng，Shi industrial and mining enterprises, port and pier, electric power, storages.Power plant's furnace bottom lime-ash delivery system has various ways, comprise the defeated slag mode that adopts belt conveyer to carry slag, because of in lime-ash containing husky, aqueous ingredients is bigger than normal, the roller bearings chamber sealing effectiveness that belt conveyer in power plant adopts is at present poor, lime-ash easily enters and in bearing chamber, causes bearing damage, very easily cause cylinder et out of order, cylinder reliability of operation is reduced; Meanwhile, design bearing bearing capacity is less than normal, can not stand the long-term operation needs of belt conveyer, and service life is on the low side; Bearing chamber is without topping up device, cannot cylinder be refueled equipment is in service.
Utility model content
Technical problem to be solved in the utility model is to overcome prior art intermediate roll sealed bearing housing weak effect, the easy et out of order of cylinder, service life low and bearing chamber without problems such as topping up devices, a kind of belt conveyer cylinder is provided.
The utility model is to address the above problem adopted technical scheme to be: a kind of belt conveyer cylinder, two bearing seats that comprise roller tube, rotating shaft and be arranged on rotating shaft two ends, rotating shaft runs through the center that is arranged on roller tube, in described each bearing seat, all coordinate bearing is installed, the inner side of described bearing seat is provided with the bearing cap shim in mating connection with rotating shaft, between bearing cap shim and rotating shaft, adopt rubber framework grease seal, the outside of described bearing seat is provided with the gland for preventing that bearing from getting loose, and gland is provided with the spiral cover grease cup communicating with bearing.
Bearing in the utility model adopts double-row self-aligning roller bearing, not only can increase the load-carrying capacity of bearing, causes the accidental damage of bearing in the time of also can avoiding, because of cylinder, decentraction is installed simultaneously.
Rotating shaft diameter in the utility model is 80mm, has improved bending resistance and the anti-twisting property of rotating shaft.
Beneficial effect: gland of the present utility model is provided with the spiral cover grease cup communicating with bearing can carry out intermittent oiling in the situation that roller tube moves, and has guaranteed normally carrying out of equipment maintenance work; Between bearing cap shim and rotating shaft, adopt rubber framework grease seal, effectively cylinder is sealed, solved lime-ash and invaded the problem of destroying bearing in bearing seat, improve cylinder reliability of operation and service life thereof.

Fig. 3 is along the cutaway view of B-B line in Fig. 2.
Reference numeral: 1, roller tube, 2, rotating shaft, 3, bearing seat, 4, bearing cap shim, 5, bearing, 6, gland, 7, spiral cover grease cup, 8, rubber framework grease seal.
The specific embodiment
A kind of belt conveyer cylinder, comprise roller tube 1, rotating shaft 2 and two bearing seats 3 that are arranged on rotating shaft 2 two ends, rotating shaft 2 runs through the center that is arranged on roller tube 1, as shown in Figure 1, general assembly schematic diagram for cylinder, as shown in Figures 2 and 3, rotating shaft 2 two ends coordinate in each bearing seat of installing and all coordinate bearing 5 is installed, the inner side of described bearing seat 3 is provided with the bearing cap shim 4 in mating connection with rotating shaft 2, between bearing cap shim 4 and rotating shaft 2, adopt rubber framework grease seal 8, the outside of described bearing seat 3 is provided with the gland 6 that prevents that bearing from getting loose, gland 6 is provided with the spiral cover grease cup 7 communicating with bearing 5, realize in equipment operation and can regularly carry out oiling work.
Above-mentioned bearing 5 is double-row self-aligning roller bearing, and the single-row roller bearing that tradition is used transform double-row self-aligning roller bearing as, has not only increased the load-carrying capacity of bearing, has avoided, because of cylinder, the accidental damage that decentraction causes bearing is installed simultaneously.
The diameter of described rotating shaft 2 is 80mm, and the rotating shaft that the diameter that tradition is used is 50mm transform 80mm as, not only can meet the operating needs of cylinder, can also improve bending resistance and the anti-twisting property of rotating shaft.
Between the utility model centre bearer lid 4 and rotating shaft 2, adopt rubber framework grease seal 8, the enclasping force of rubber framework grease seal 8 generations, can overcome rotating shaft 2 under slew mode because of vibration, the play of rotating shaft 2 and the gap of beating and producing; Gland 6 is provided with the spiral cover grease cup 7 communicating with bearing 5, when equipment operation, can regularly carry out oiling work, in annular seal space under the effect of oil pressure, lubricating oil can infiltrate the oil film that forms thin layer between rubber framework grease seal 8 and rotating shaft 2, oil film is subject to, under the capillary effect of fluid, can prevent that fluid is excessive, plays the effect of sealing.
