Abstract
The utility model discloses a coal mine conveying roller. The coal mine conveying roller comprises a shaft and a roller body, wherein the roller body is sleeved outside the shaft, a rubber buffering layer is wrapped on the side wall of the roller body, a plurality of salient points are formed on the surface of the rubber buffering layer, a bearing mounting groove is formed on the end part of the roller body, the end part of the shaft penetrates through the bottom of the groove, a bearing is arranged on the shaft, a seal ring is installed outside the bearing, an outer retaining ring is installed on the opening part of the groove, and an axial seal ring is arranged between the shaft and the roller body. The coal mine conveying roller has good sealing performance, is convenient to install and use and has a long service life.
Description
Technical field
The utility model relates to a kind of coal ore conveying roller.
Background technology
Impact idler (impact idler), impact idler is used for belt conveyer material feeding place and slows down blanking to the impact of load-transfer device, mainly for corrosive atmospheres such as washery, coke-oven plant, chemical plant and a class carrying roller of developing, impact idler is lightweight, and rotatory inertia is little.The carrying roller great majority adopt special-purpose High molecular material lightweight, and proportion is 1/7th of steel, and with the carrying roller that this material is made, weight is about 1/2nd of common carrying roller, and rotatory inertia is little, and the friction between carrying roller and the belt is little.
The unreasonable structure, the poor sealing that have impact idler in the existing technology cause reducing the service life of buffer roll intentionally in the use procedure.
The utility model content
The utility model provides the coal ore conveying roller of a kind of good airproof performance, easy to install, long service life.
The utility model technical solution problem provides following scheme:
A kind of coal ore conveying roller, comprise axle, roll body, it is characterized in that: the outer cover of described axle has roll body, be enclosed with cushion rubber layer on the sidewall of described roll body, the surface of described cushion rubber layer is provided with a plurality of salient points, and the end of described roll body is provided with bearing groove is installed, and the end of described axle is passed the bottom of groove and bearing is installed, the outside of described bearing is equipped with seal ring, and the oral area of described groove is equipped with outer back-up ring.
Be provided with Simmer ring between described axle and the roll body.
The utility model arranges bearing in the end of roll body, seal ring is installed outside bearing, and at the seal ring outer gland sealing back-up ring is installed, reduced the generation of the stuck phenomenon of bearing, outer wall at roller is provided with cushion rubber layer, be provided with a plurality of salient points on the surface of cushion layer, increase the friction of load-transfer device and roller, effectively reduce the phenomenon of belt deviation.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Referring to accompanying drawing, a kind of coal ore conveying roller, comprise axle 1, roll body 2, the outer cover of described axle 1 has roll body 2, be enclosed with cushion rubber layer 3 on the sidewall of described roll body 2, the surface of described cushion rubber layer 3 is provided with a plurality of salient points 4, the end of described roll body 2 is provided with bearing groove 5 is installed, the end of described axle 1 is passed the bottom of groove 5 and bearing 6 is installed, the outside of described bearing 6 is equipped with seal ring 7, the oral area of described groove 5 is equipped with outer back-up ring 8, is provided with Simmer ring 9 between described axle 1 and the roll body 2.
Claims (2)
