Abstract
A special coal mine carrier roller bearing with a high sealing performance comprises a bearing outer ring, a bearing inner ring and a steel ball retainer, wherein the steel ball retainer is disposed between the bearing outer ring and the bearing inner ring, sealing rings are respectively arranged on two sides of the steel ball retainer, an annular clamping groove is arranged on the inner side of the bearing outer ring and the outer side of the bearing inner ring respectively, and the sealing rings are fastened between the bearing outer ring and the bearing inner ring. The special coal mine carrier roller bearing has the advantages that the sealing rings are arranged between the bearing outer ring and the bearing inner ring, dust is effectively prevented from entering the bearing to jam the bearing, service life of the bearing is prolonged, and static electricity is reduced and accidents caused by static sparks are avoided since no dust enters the bearing.
Description
Technical field
The utility model relates to a kind of bearing, is specifically related to the high colliery carrying roller special bearing of a kind of sealing property.
Background technology
At present, the carrying roller conveyor shaft bearing structure that use in the colliery is unreasonable, and retainer poor performance, sealing property can not satisfy working condition requirement, practical life is short.Because the coal mine working environment is poor especially, dust is big, load is heavy, carrying roller line speed height, and this just has a strong impact on the production efficiency in colliery.Because the bad working environments of many dust on the ore deposit, the destruction majority of Mine bearing causes because of and friction stuck owing to dust under the bad working environments.In addition, bearing produces static and causes that electro spark can cause accident, causes enormous economic loss in operation process.
The utility model content
The purpose of this utility model is to solve the above-mentioned problems in the prior art, and a kind of colliery carrying roller special bearing of good seal performance is provided.
For achieving the above object, the technical solution adopted in the utility model is as follows:
The colliery carrying roller special bearing that sealing property of the present utility model is high, comprise outside race, bearing inner ring and place outside race and bearing inner ring between the steel ball retainer, be respectively equipped with seal ring in steel ball retainer both sides, be provided with annular slot in the outside race inboard and the bearing inner ring outside, seal ring is buckled between outside race and the bearing inner ring.
Described seal ring is made up of steel ring and the rubber ring that is wrapped in the steel ring periphery, is provided with flexible outer lip edge and epipharynx edge in the outer edge and the inside edge of seal ring.
Described steel ball retainer is the steel retainer.
Because bearing of the present utility model adopts steel retainer, lifting capacity height.Between outside race and bearing inner ring, be provided with seal ring, prevented that effectively dust from entering bearing inside, cause the phenomenon of stuck bearing, prolonged the practical life of bearing.Because the inner dust of bearing does not have dust to enter, and has reduced the generation of static, has avoided because the danger of the accident that electrostatic spark causes.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is that the A-A of Fig. 1 is to partly cuing open figure.
The specific embodiment
As shown in Figure 1, the colliery carrying roller special bearing that sealing property of the present utility model is high, comprise outside race 1, bearing inner ring 3 and place outside race and bearing inner ring between steel ball retainer 4, be respectively equipped with seal ring 2 in steel ball retainer both sides, be provided with annular slot in the outside race inboard and the bearing inner ring outside, seal ring 2 is buckled between outside race 1 and the bearing inner ring 3.
Described seal ring is made up of steel ring 3-2 and the rubber ring 3-3 that is wrapped in the steel ring periphery, be provided with in the outer edge of seal ring and inside edge flexible outer lip along 3-1 and epipharynx along 3-4.Described steel ball retainer is the steel retainer.
Claims (3)
1. colliery carrying roller special bearing that sealing property is high, comprise outside race, bearing inner ring and place outside race and bearing inner ring between the steel ball retainer, it is characterized in that: be respectively equipped with seal ring in steel ball retainer both sides, be provided with annular slot in the outside race inboard and the bearing inner ring outside, seal ring is buckled between outside race and the bearing inner ring.
