Abstract
The utility model provides a bearing with small friction force. The bearing comprises an inner ring and an outer ring sleeved outside the inner ring, wherein a plurality of steel balls are arranged between the inner ring and the outer ring in a rolling mode; a retainer is sleeved on the steel balls; a bayonet is arranged between the inner ring and the outer ring at the two ends of the bearing; a dustproof cover is clamped in the bayonet; an accommodating groove is formed in the dustproof cover; the accommodating groove is filled with a straining ring; the inner ring is provided with an inner ring ditch with ditch curvature of 0.88+0.02/0; and the outer ring is provided with an outer ring ditch with the ditch curvature of 0.90+0.02/0. Compared with the prior art, the bearing has the advantages of reducing the friction force, reducing the production precision and the required cost, ensuring that the interior and the surface of the product are difficult to damage, prolonging the service life of the product and improving the production efficiency equally.
Description
Technical field
The utility model relates to a kind of bearing, refers to especially the bearing that a kind of frictional force is little.
Background technique
Bearing is to work the parts of fixing and reducing the load friction factor in mechanical transmission course.Also can say, when other parts produce relative movement each other on axle, be used for reducing the fixing parts of friction factor and retainer shaft central position in the power transmission process.Bearing is a kind of very important component in the contemporary machinery.Its major function is the supported mechanical solid of rotation, in order to the mechanical load friction factor of reduction equipment in transmission process.Existing pivot friction power is large, and the easy loss of the internal structure of product reduces the life-span of product, and ditch curvature is little, and permissible accuracy is also relatively high, and efficient can reduce when causing producing, and makes product can not get good guarantee.
The model utility content
The utility model proposes the little bearing of a kind of frictional force, solved in the prior art frictional force large, the problem of the easy loss of internal structure of product.
The technical solution of the utility model is achieved in that
The bearing that a kind of frictional force is little, described bearing comprises inner ring and is placed in the outer ring of this inner ring outside, rollably be provided with some steel balls between described inner ring and the outer ring, and be placed in retainer on the described steel ball, be provided with bayonet socket between the inner ring at described bearing two ends and the outer ring, described dust cover is stuck in this bayonet socket, described dust cover inside is provided with containing groove, be filled with described collar in the described containing groove, it is characterized in that: described inner ring is provided with the bear inner ring grooved railway that ditch curvature is 0.88+0.02/0, and the outer ring is provided with the outer ring raceway that ditch curvature is 0.90+0.02/0.
Described retainer is by half retainer, and the second retainer constitutes, and described steel ball is embedded between outer ring and the inner ring by retainer.
Compared with prior art, the utility model has the advantage of, reduce friction, can and require cost with the precision of producing, make interiors of products and surface not fragile, prolongation product service time, the efficient of production also gets a promotion on an equal basis.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is embodiments more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the generalized section of the little bearing of a kind of frictional force of the utility model;
Fig. 2 is the explosive view of the little bearing of a kind of frictional force of the utility model.
The number in the figure explanation:
1-outer ring, 2-inner ring, 3-half retainer, 4-the second retainer, 5-steel ball, 6-dust cover, 7-collar
Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technological scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiments.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment who obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figures 1 and 2, the bearing that a kind of frictional force is little, described bearing comprises inner ring 2 and is placed in the outer ring 1 of these inner ring 2 outsides, rollably be provided with some steel balls 5 between described inner ring 2 and the outer ring 1, and be placed in retainer on the described steel ball 5, be provided with bayonet socket between the inner ring 2 at described bearing two ends and the outer ring 1, described dust cover 6 is stuck in this bayonet socket, described dust cover 6 inside are provided with containing groove, be filled with described collar 7 in the described containing groove, described inner ring 2 is provided with the bear inner ring grooved railway that ditch curvature is 0.88+0.02/0, and outer ring 1 is provided with the outer ring raceway that ditch curvature is 0.90+0.02/0.Described retainer is constituted by half retainer, 3, the second retainers 4, and described steel ball 5 is embedded between outer ring 1 and the inner ring 2 by retainer.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
Claims (2)
1. bearing that frictional force is little, described bearing comprises inner ring and is placed in the outer ring of this inner ring outside, rollably be provided with some steel balls between described inner ring and the outer ring, and be placed in retainer on the described steel ball, be provided with bayonet socket between the inner ring at described bearing two ends and the outer ring, described dust cover is stuck in this bayonet socket, described dust cover inside is provided with containing groove, be filled with described collar in the described containing groove, it is characterized in that: described inner ring is provided with the bear inner ring grooved railway that ditch curvature is 0.88+0.02/0, and the outer ring is provided with the outer ring raceway that ditch curvature is 0.90+0.02/0.
