Description
Technical field
The utility model relates to technical field of mining equipment, particularly relates to a kind of coalcutter belt pulley.
Background technology
Coalcutter is one and integrates large-scale complicated system that is mechanical, electric and hydraulic pressure, and work under bad environment, will cause the interruption of whole coal work if there is fault, cause huge economic loss.Coalcutter realizes one of coal production mechanization and modern visual plant.Mechanical coal mining can alleviate manual labor, improve safety, reaches high yield, high efficiency, low consumed object.Coalcutter divides sawing formula, planing pattern, drilling formula and milling type four kinds.Along with the development of coal industry, the function of coalcutter gets more and more, and the structure of himself, composition more sophisticated, thus the reason of et out of order is also thereupon complicated.Double-ended shearer combines the successful experience of domestic and international low seam mining machinery, is the novel high-power low seam mining machinery designed for China's specific national conditions.Current coalcutter needs to use belt pulley when carrying ore or colliery, but the periphery of the belt pulley in conventional art is processed with the structure of belt grooves, during use, belt is embedded in the belt grooves on belt pulley, drive driven pulley to rotate by driving pulley and realize mechanical rotation work, but, in the process that belt pulley rotates, mostly wall due to the belt grooves both sides of current belt pulley is level and smooth light face, and the problem of skidding often appears in belt in the belt grooves of belt pulley.
Utility model content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of coalcutter belt pulley, prevents from skidding and can improving its stable working.
The utility model is achieved through the following technical solutions:
A kind of coalcutter belt pulley, comprise two symmetrically arranged belt wheel bodys, be set in parallel in the belt between two belt wheel bodys, each belt wheel body offers belt grooves along its circumference, described belt is arranged in belt grooves, and the both sides of belt grooves are provided with baffle plate, is provided with two bearings in described belt wheel body, run through in the inner ring of bearing and be provided with adapter shaft, the inwall of belt grooves is provided with texture.
As optimal technical scheme of the present utility model, the side of described adapter shaft is provided with fastener, and a side of described fastener and the end contact of belt wheel body, the other end of belt wheel body is provided with cushion, and described cushion is through adapter shaft.
As optimal technical scheme of the present utility model, described bearing is tapered roller bearing, is symmetricly set on the both sides of belt wheel body.
As optimal technical scheme of the present utility model, the cross section of described belt grooves is isosceles trapezoid, and upper end open is large, and lower ending opening is little.
Compared with prior art, the beneficial effects of the utility model are: the utility model structure is simple, reasonable in design, easy to use, by being provided with baffle plate, prevent belt from skidding in belt grooves, the wall of belt grooves is provided with texture, make its wall crude and good antiskid effect, make belt in belt grooves, be not easy the problem occurring skidding; By being provided with bearing, can reducing wear, life-saving, when carrying ore or coal, working more steady.

Fig. 2 is the structural representation of the utility model belt pulley.
In figure: 10-belt wheel body; 20-belt; 30-belt grooves; 40-baffle plate; 50-bearing; 60-adapter shaft; 70-fastener; 80-cushion.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1 and Fig. 2, Fig. 1 is structural representation of the present utility model, and Fig. 2 is the structural representation of the utility model belt pulley.
Described a kind of coalcutter belt pulley, comprise two symmetrically arranged belt wheel bodys 10, be set in parallel in the belt 20 between two belt wheel bodys 10, each belt wheel body 10 offers belt grooves 30 along its circumference, the cross section of described belt grooves 30 is isosceles trapezoid, and upper end open is large, lower ending opening is little.Described belt 20 is arranged in belt grooves 30, and the both sides of belt grooves 30 are provided with baffle plate 40, is provided with two bearings 50 in described belt wheel body 10, runs through being provided with adapter shaft 60, the inwall of belt grooves 30 is provided with texture in the inner ring of bearing 50.By being provided with baffle plate 40, preventing belt 20 from skidding in belt grooves 30, the wall of belt grooves 30 is provided with texture, making its wall crude and good antiskid effect, make belt 20 in belt grooves 30, be not easy the problem occurring skidding; By being provided with bearing 50, can reducing wear, life-saving, when carrying ore or coal, working more steady.
The side of described adapter shaft 60 is provided with fastener 70, and a side of described fastener 70 and the end contact of belt wheel body 10, the other end of belt wheel body 10 is provided with cushion 80, and described cushion 80 is through adapter shaft 60.Described bearing 50 is tapered roller bearing, be symmetricly set on the both sides of belt wheel body 10, it belongs to divergence type bearing, the inside and outside circle of bearing all has tapered raceway, when bearing bears Radial load, an axial component will be produced, so when needing another bearing that can bear reversing sense axial force to be balanced.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
