Abstract
The utility model provides a sealed self-aligning roller bearing comprising an inner ring and an outer ring, wherein, a holding rack is arranged between the inner and the outer rings, and rollers arearranged on two sides of the holding rack between the inner and the outer rings. The utility model is characterized in that end covers used for sealing the interior of the bearing are arranged on theend surfaces of two sides of the inner and the outer rings. The end covers can effectively shield the internal structure of the bearing from external threads, thereby prolonging the service life of the bearing and enabling the bearing to serve a long time under such complex environmental conditions as high temperature, high pressure, heavy load and the like.
Description
Technical field
The utility model relates to a kind of roller bearing, concrete, relate to a kind of selfaligning roller bearing that has seal arrangement.
Background technique
At present, being useful in that selfaligning roller bearing is general is mechanically various.This common roller bearing generally contains inner ring and outer ring, has retainer between inner ring and the outer ring, and the both sides of this retainer are evenly equipped with axial pocket hole, the cross-shaped layout in pocket hole of its both sides.In each pocket hole roller is arranged all, roller is dolioform spherical roller.The internal surface of outer ring and be sphere with the corresponding inner ring raceway of roller.Be processed with circumferential boss in the middle of wherein the retainer inner side surface, be between the internal surface of this circumferential boss and the internal surface of inner ring and contact shape and be slidingly matched, guide retainer to move by inner ring.
But because selfaligning roller bearing is widely used in the comparatively abominable operating conditions of environment, if directly will plant common selfaligning roller bearing is installed in the above-mentioned environment, bearing inside is contaminated easily, significantly reduces the life-span of bearing, influences the normal operation of equipment.
The model utility content
Technical problem to be solved in the utility model is, overcomes the inner easy contaminated problem of existing selfaligning roller bearing, and a kind of sealing selfaligning roller bearing is provided.
In order to address the above problem the technical solution of the utility model is such:
The sealing selfaligning roller bearing comprises inner ring and outer ring, is provided with retainer between inner ring and the outer ring, and the retainer both sides are provided with roller between inner ring and the outer ring, it is characterized in that, the both sides end face of inner ring and outer ring is provided with the end cap that is used for stuffing box bearing inside.
Described end cap is a sheet ring end cap, and the bi-side of inner ring and outer ring are provided with the groove that is used to hold end cap, and described end cap is embedded in the groove.
Described groove can't outwards be deviate from after end cap is embedded in the groove for embedding the shape groove.
Beneficial effect; sealing selfaligning roller bearing described in the utility model; can be widely used in the comparatively abominable place of environment; as be applied in engineering machinery field such as Ferrous Metallurgy, mine, petrochemical industry, papermaking, cement manufacturing; be provided with the end cap of sealing; the bearing internal structure that can effectively protect is avoided outside infringement, has prolonged bearing working life, can make bearing long-play under the condition of circumstance complications such as high temperature, high pressure, heavy duty.
Description of drawings
Describe the utility model in detail below in conjunction with the drawings and specific embodiments;
The structural representation of the sealing selfaligning roller bearing that Fig. 1 tells for the utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1
Sealing selfaligning roller bearing described in the utility model comprises inner ring 1, outer ring 2; And being arranged on the middle retainer 3 of inner ring and outer ring, the both sides of retainer 3 are provided with the pocket hole of symmetry, are provided with roller 4 in each pocket hole.Roller 4 is being arranged in inner ring 1 and the outer ring 2 of biserial symmetry like this.2 outer middle side part also is provided with house and is free 5 in the outer ring in addition, can think the inner filling of bearing lubricant oil by tank filler sleeve 5.
Because the working environment of selfaligning roller bearing is more abominable, impurity such as dust often enter bearing internal contamination bearing easily, and bearing service life is reduced.So bearing described in the utility model is provided with groove 6 in the end face inside, both sides of bearing inner race 1 and outer ring 2, groove is embedded in an end cap that seals 7, and is provided with groove and end cap in the both sides of bearing, protects bearing to avoid polluting from both sides.End cap 7 is the ring sheet structure, and rubber material is made, and can't outwards deviate from afterwards in end cap 7 embedded grooves 6, has guaranteed the stability and the reliability of end cap 7.
The inner ring 1 of described bearing, outer ring 2, roller 4 are Bearing Steel, and afterwards structural stability is firm to carry out the stabilization processing.Retainer 3 can adopt engineering plastics to make.Owing to be provided with end cap 7, can reach lubricated or lubricated throughout one's life purpose of bearing length time.It is better that lubriation material is chosen material lubrication effects such as poly-urine, sulfoacid calcium.
Sealing selfaligning roller bearing described in the utility model has effects such as long lifetime, high temperature resistant, dustproof, waterproof.Can be widely used in the comparatively abominable place of environment, as be applied in engineering machinery field such as Ferrous Metallurgy, mine, petrochemical industry, papermaking, cement manufacturing.Can be under the condition of 250 ℃-280 ℃ of high temperature, long-time efficient stable turns round reliably.Be provided with the end cap of sealing, the bearing internal structure that can effectively protect is avoided outside infringement, has prolonged bearing working life, can the time bearing long-play under the condition of circumstance complications such as high temperature, high pressure, heavy duty.
More than show and described basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
Claims (3)
1, sealing selfaligning roller bearing, comprise inner ring and outer ring, be provided with retainer between inner ring and the outer ring, the retainer both sides are provided with roller between inner ring and the outer ring, it is characterized in that the both sides end face of inner ring and outer ring is provided with the end cap that is used for stuffing box bearing inside.
2, sealing selfaligning roller bearing according to claim 1 is characterized in that, described end cap is a sheet ring end cap, and the bi-side of inner ring and outer ring are provided with the groove that is used to hold end cap, and described end cap is embedded in the groove.
