Abstract
The utility model discloses a double-row roller single-row steel ball coupled combined bearing, which is used for solving the ubiquitous problems that a single-row roller single-row steel ball coupled combined bearing cannot bear radial alternating force from a high load and steel balls are easy to damage. The double-row roller single-row steel ball coupled combined bearing comprises a ferrule, a bearing shaft, a steel ball retainer, steel balls, roller retainers, rollers, a sealing ring and a dustproof cover, and is mainly characterized in that a single row of steel ball retainer is arranged on a shaft at the central position of the bearing shaft; double rows of roller retainers are arranged on shafts of the bearing shaft, which are positioned on the two sides of the steel ball retainer; and the sealing ring and the dustproof cover are arranged on the outer sides of the roller retainers. Compared with the conventional single-row roller structure, the double-row roller single-row steel ball coupled combined bearing has the advantages that the capacity of bearing a radial load is greatly improved, the problem that the steel balls are easy to damage is effectively solved, and the combined bearing is widely applied to a cooling fan seat of a diesel engine.
Description
Technical field
The utility model relates to a kind of bearing, particularly relates to the single-row steel ball connecting shaft of a kind of biserial roller combination bearing.
Background technique
The bearing species, the pattern that are used for transmission system in the existing mechanical industry are quite a lot of; The single-row steel ball connecting shaft of wherein a kind of single-row roller combination bearing is as shown in Figure 1; Its structure comprises lasso, bearing shaft, ball retainer, steel ball, roller, roller rolling retainer, seal ring and door; Wherein retainer is contained in and is used for uniform distribution steel ball or roller on the axle; And ball retainer is contained in the front end of bearing shaft, and single-row roller rolling retainer is loaded on the rear end of bearing shaft, and seal ring is loaded on the both ends of the surface of bearing shaft.From this bearing structure, can find out; It is to have adopted a row roller; One row steel ball also is referred to as the connecting shaft structure of the single-row steel ball of single-row roller, and the bearing of this structure is used often, but its maximum defective is the radially alternating force that can not carry bigger load; And steel ball is carrying respectively and is radially reaching axial load, so steel ball is fragile.How to improve the radially alternating force of this connecting shaft textural association bearing, be the problem of bearing industry research always.
The model utility content
The purpose of the utility model is that the single-row steel ball connecting shaft of a kind of biserial roller combination bearing will be provided, to solve the existing defective of connecting shaft combination bearing of the existing single-row steel ball of single-row roller, the working life of improving this combination bearing.The single-row steel ball connecting shaft of this biserial roller combination bearing can adopt following technological scheme to implement: it comprises lasso, bearing shaft, ball retainer, steel ball, roller, roller rolling retainer, seal ring and door; Wherein one group of steel ball is evenly distributed on the ball retainer; Ball retainer is installed on the central position axle of bearing shaft; One group of roller is evenly distributed on the roller rolling retainer; Two roller rolling retainers are installed in respectively on the two end axles of bearing shaft (that is being contained on two side shafts of ball retainer), load onto the door of seal ring and dustproof usefulness respectively in the outside of roller rolling retainer, just constitute the single-row steel ball connecting shaft of biserial roller combination bearing.The component making of this connecting shaft combination bearing and assembly technology and the single-row steel ball connecting shaft of existing single-row roller combination bearing are same or similar.
The single-row steel ball connecting shaft of the biserial roller combination bearing that designs and produces according to the said structure form compared with prior art, its outstanding feature is:
1, the utility model has adopted biserial roller, single-row steel ball connecting shaft structure, and two row roller rolling retainers are configured in the ball retainer both sides, and is a lot of thereby the bearing capacity of radial load improves.If with compare with the single-row steel ball bearing of the single-row roller of volume, its radially bearing capacity increase more than 13%, and steel ball only carrying axial load, no longer carry radial load, and radial load carried by roller all, so solved the defective of steel ball rapid wear.
2, compare with existing connecting shaft airframe bearing, assembling is simple, and quality is very easily controlled.Be applied on the DENG cooling fan seat, not only solved radially alternating force problem, and greatly reduce the rate of fault of fan.
Description of drawings
Fig. 1, the single-row steel ball connecting shaft of single-row roller combination bearing.
The single-row steel ball connecting shaft of the biserial roller combination bearing of Fig. 2, the utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further narration.
As shown in Figure 2; The single-row steel ball connecting shaft of the biserial roller combination bearing of the utility model comprises lasso 1, bearing shaft 2, ball retainer 3, steel ball 4, roller 5, roller rolling retainer 6, seal ring 7 and door 8; Wherein one group of steel ball totally 6 be evenly distributed on the ball retainer 3; Ball retainer 3 is installed on the central position axle of bearing shaft 2; One group of roller 5 totally 10 be evenly distributed on the roller rolling retainer 6, two roller rolling retainers are installed in respectively on the two end axles of bearing shaft 2 (that is both sides of ball retainer 3), load onto seal ring and dustproof door 8 respectively in the outside of roller rolling retainer.The component making of the single-row steel ball connecting shaft of above-described biserial roller combination bearing and assembly technology and the single-row steel ball connecting shaft of existing single-row roller combination bearing are same or similar.This connecting shaft combination bearing is mainly used on the DENG cooling fan seat, can overcome bigger radially alternating force, has reduced the rate of fault of fan.
