Abstract

The utility model relates to a strengthened bearing, which comprises an inner ring, an outer ring, a plurality of rollers and a retainer, wherein the rollers are arranged between the inner ring and the outer ring. Besides, the retainer comprises two end caps and connectors, the two end caps are arranged in parallel along the axial direction of the inner ring, the connectors are used for connecting the two end caps, projections in the number matched with that of the rollers are arranged on opposite sides of the two end caps, the rollers are provided with recesses corresponding to the projections of the two end caps respectively, and the projections of the two end caps can be inserted into the recesses movably. According to the technical scheme, the strengthened bearing has fine radial bearing capacity, and the strength of the retainer is guaranteed to be enough.

Description

A kind of reinforced bearing

Technical field

The utility model relates to a kind of bearing, particularly a kind of reinforced bearing.

Background technique

At present, existing bearing generally comprises inner ring, outer ring and is arranged on some rollers, the retainer between inner ring, the outer ring; Because its assembly environment is restricted, when it radially carries greatly, generally satisfy the demand through the quantity that increases roller; Yet; In limited space, increase the quantity of roller, just need retainer that enough intensity is arranged, and the retainer of existing bearing can not be satisfied the demand.

Summary of the invention

The purpose of the utility model: in order to overcome the defective of existing technology, the utility model provides a kind of reinforced bearing, when bearing has preferably radially bearing capacity, can guarantee that again retainer has enough intensity.

The technological scheme of the utility model: a kind of reinforced bearing; Include inner ring, outer ring and be arranged on some rollers, the retainer between inner ring, the outer ring; Described retainer includes along the two end cap of inner ring parallel to an axis setting and the link that is used to connect two end cap; Be equipped with the convexity that is complementary with roller quantity on the described two end cap opposing side; The raised position of described roller opposite ends lid is respectively equipped with depression, and the convexity of described two end cap is inserted in the depression of roller respectively movably.

Adopt technique scheme, when bearing had preferably radially bearing capacity, described retainer had enough intensity again, thereby can make bearing when assembly environment is restricted, and still can have well radially bearing capacity.

The further setting of the utility model: described link is a rivet.

Adopt above-mentioned further setting, adopt rivet to connect, simple in structure, cost is low and can guarantee the intensity of retainer.

Embodiment

Like Fig. 1,2, shown in 3; A kind of reinforced bearing; Include inner ring 1, outer ring 2 and be arranged on some rollers 3, the retainer 4 between inner ring 1, the outer ring 2; Described retainer 4 includes along the two

end cap

41,42 of inner ring 1 parallel to an axis setting and the link that is used to connect two

end cap

41,42; Be equipped with the convexity 411,421 that is complementary with roller quantity on described two

end cap

41,42 opposing sides, convexity 411,421 positions of described roller 3

opposite ends lid

41,42 are respectively equipped with

depression

31,32, and the convexity 411,421 of described two

end cap

41,42 is inserted respectively in the

depression

31,32 of roller 3 movably.Described link is a rivet 5, and corresponding position is provided with and connects positioning hole 412,422 on the described two

end cap

41,42, certainly, also can adopt other links such as locating stud.Wherein, the convexity 411,421 of two

end cap

41,42 is inserted in the

depression

31,32 of roller promptly protruding 411,421 not only positioning roller 3 but also can guarantee that roller 3 can roll well respectively movably.In the utility model specific embodiment, described roller 3 is a cylindrical roller.

In the utility model specific embodiment, described

end cap

41,42 all adopts SPCC to process.
