Abstract
The utility model provides a double row angular contact ball bearing with a punched helical cage, and an inner ring and an outer ring integrally inseparable, and the double row angular contact ball bearing overcomes the shortage that an existing double row angular contact ball bearing cannot be applied to occasions as small axial spaces, large load and the like, and comprises outer rings, inner rings, dustproof covers, steel balls and cages, wherein each cage is of a punched helical structure, and end faces of the outer rings and the inner rings are changed from a structure symmetrical about a raceway to an unsymmetrical structure. One outer ring, one steel ball and one cage form a component row, then another steel ball is loaded in from a feed inlet through the other inner ring and the other cage to form another component row, each dustproof cover is abutted into a dent of the outer ring and the inner ring, and finally the inseparable bearing is formed. The double row angular contact ball bearing can bear a radial load and bidirectional axial loads, has fine rigidity and large bearable overturning moment.
Description
Technical field
The utility model relates to a kind of double-row angular contact bal bearing, particularly can bear the Inseparably integrated inner and outer ring punched snake-shaped cage double-row angular contact bal bearing of radial and axial load simultaneously.
Background technique
Current, the double-row angular contact bal bearing of employing is made up of two outer rings or two inner ring, steel ball, split brass solid cage.If, load little at axial space is big and when dustproof the requirement arranged, said structure just can not meet the demands, this just requires to have a kind of new structure to meet the need of market.Because the retainer material is a casting brass, also strengthened the bearing manufacture cost in addition.
Summary of the invention
At above deficiency, the purpose of this utility model provides a kind of Inseparably integrated inner and outer ring punched snake-shaped cage double-row angular contact bal bearing.This bearing can bear simultaneously radially and act on the both direction axial load, the axial displacement of two directions of restrictive axes, and good rigidly, and it is big to bear tilting moment.
The technical solution of the utility model is: a kind of Inseparably integrated inner and outer ring punched snake-shaped cage double-row angular contact bal bearing, to form by outer ring 1, inner ring 2, dust cover 3, steel ball 4 and retainer 5, and retainer 5 is the punching press serpentine configuration; Inner ring 2, outer ring 1 end face are asymmetric about raceway ditch position; Outer ring 1, steel ball 4 and retainer 5 are formed a row assembly, form another row assembly by inner ring 2 and retainer 5 by the ball-loading hole steel ball 4 of packing into again, and dust cover 3 is pressed against in the alveolus of outer ring 1 and inner ring 2, forms non-separable bearing at last.
The beneficial effects of the utility model are: can bear radially and act on both direction axial load, the axial displacement of two directions of restrictive axes simultaneously; Compare that entity shelf structure bearing cost is low, rotating speed is high, good rigidly, can bear that tilting moment is big, the life-span is long, and reliability height, stability are strong; Be easy to dismounting and maintenance.
Description of drawings
Below in conjunction with the drawings and the specific embodiments the utility model is elaborated:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the utility model retainer structural representation;
Fig. 3 is the A-A sectional drawing of the utility model retainer structure.
Among the figure, 1, the outer ring, 2, inner ring, 3, dust cover, 4, steel ball, 5, retainer.
Embodiment
As attached illustrated in figures 1 and 2, the utility model is made up of outer ring 1, inner ring 2, dust cover 3, steel ball 4 and retainer 5, and retainer 5A-A sectional drawing and for example shown in Figure 3 is the punching press serpentine configuration; Inner ring, cycle surface are about raceway ditch position asymmetric (traditional outer ring and inner ring end face are about raceway ditch position symmetry); Outer ring 1, steel ball 4 and retainer 5 are formed a row assembly, form another row assembly by inner ring 2 and retainer 5 by the ball-loading hole steel ball 4 of packing into again, and dust cover 3 is pressed against in the alveolus of outer ring 1 and inner ring 2, forms non-separable bearing at last.
