Abstract
The utility model discloses a roller bearing sealing structure, which comprises a shaft and a roller body. The roller body is sheathed at the external part of the shaft. 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. Outer retainer rings are installed at the mouths of the grooves. A shaft sealing ring is arranged between the shaft and the roller body. The roller bearing sealing structure has the advantages of good sealing performance, convenience in use and installation and long service life.
Description
Technical field
The utility model relates to a kind of roller bearing hermetically-sealed construction.
Background technology
Comb type carrying roller is carrying roller accessory, carrying roller production facilities.Comb shape cleaning carrying roller can be comb type carrying roller.Comb type carrying roller is exclusively used in the conveyer of carrying viscous material and uses, a class carrying roller of developing mainly for the corrosive atmosphere such as washery, coke-oven plant, chemical plant, and 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 roller bearing hermetically-sealed construction 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 roller bearing hermetically-sealed construction, comprise axle, roll body, it is characterized in that: the outer cover of described axle has roll body, 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, 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, and seal ring is installed outside bearing, and at the seal ring outer gland sealing back-up ring is installed, and has reduced the generation of the stuck phenomenon of bearing.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Referring to accompanying drawing, a kind of roller bearing hermetically-sealed construction, comprise axle 1, roll body 2, the outer cover of described axle 1 has roll body 2, the end of described roll body 2 is provided with bearing groove 3 is installed, and the end of described axle 1 is passed the bottom of groove 3 and bearing 4 is installed, and the outside of described bearing 4 is equipped with seal ring 5, the oral area of described groove 3 is equipped with outer back-up ring 6, is provided with Simmer ring 7 between described axle 1 and the roll body 2.
