Abstract
The utility model discloses a coal ore conveying dustproof roller, which comprises a shaft and a roller body. The roller body is sheathed at the external part of the shaft. A rubber layer is arranged on each side wall of the roller body. Each rubber layer is provided with an axial through hole. Bearing installation grooves are arranged at the end parts of the roller body. The end parts of the shaft penetrate through the bottoms of the grooves and are provided with bearings. Sealing rings are installed on the external sides of the bearings. Clamping grooves are arranged at the mouths of the grooves. Dustproof covers are installed in the clamping grooves at the mouths of the grooves. Retainer rings are respectively and fixedly installed at the two ends of the roller body. A shaft sealing ring is arranged between the shaft and the roller body. The coal ore conveying dustproof roller has the advantages that the sealing performance is good, the roller is convenient to install and use, the service life is long and the belt is prevented from running out.
Description
Technical field
The utility model relates to a kind of coal ore and carries dustproof 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 a kind of good airproof performance, easy to install, long service life, avoids the coal ore of belt deviation to carry dustproof roller.
The utility model technical solution problem provides following scheme:
A kind of coal ore is carried dustproof roller, comprise axle, roll body, it is characterized in that: the outer cover of described axle has roll body, the sidewall of described roll body is provided with rubber layer, described rubber layer is provided with axial through hole, the end of described roll body is provided with bearing groove is installed, 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, the oral area of described groove is provided with draw-in groove, in the oral area draw-in groove of described groove cover of dust is installed, described roll body is installed with respectively back-up ring on the two ends.
Be provided with Simmer ring between described axle and the roll body.
The utility model arranges bearing in the end of roll body, and seal ring is installed outside bearing, and at the seal ring outer gland sealing cover of dust is installed, effectively reduced entering of dust, prevent that bearing from advancing ash and causing wear-out of a bearing, and be respectively equipped with back-up ring at the two ends of roller, effectively avoided the sideslip of load-transfer device.
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 is carried dustproof roller, comprise axle 1, roll body 2, the outer cover of described axle 1 has roll body 2, the sidewall of described roll body 2 is provided with rubber layer 3, described rubber layer 3 is provided with axial through hole 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, and the oral area of described groove 5 is provided with draw-in groove 8, in the oral area draw-in groove 8 of described groove 5 cover of dust 9 is installed, described roll body is installed with respectively back-up ring 10 on 2 two ends, is provided with Simmer ring 11 between described axle 1 and the roll body 2.
