Abstract

The utility model discloses a simple bearing, comprising an outer shaft sleeve and an inner shaft sleeve. The outer shaft sleeve is installed on the inner shaft sleeve. The bearing is characterized in that the vertical direction is taken as the axial direction of the outer shaft sleeve and the inner shaft sleeve. The outer shaft sleeve is formed by a lower cover and an upper cover which are buckled together with each other. The centers of the lower cover and the upper lower are separately provided with holes which have the same size. The diameter of the hole is slightly larger than the outer diameter of the inner shaft sleeve. The two ends of the inner shaft sleeve separately pass through the holes on the lower cover and the upper cover. A convex sliding sleeve is arranged around the outer wall of the inner shaft sleeve. The outer diameter of the convex sliding sleeve is slightly less than the inner diameter of the lower cover. The convex sliding sleeve is located inside the lower cover. The height of the convex sliding sleeve is almost identical to the height of the lower cover. The simple bearing has fewer parts and is quite convenient to be assembled and disassembled. The process is much simpler, and the cost of manufacture, using and maintaining is also reduced.

A kind of simple and easy bearing

Technical field

The utility model relates to a kind of bearing, relates in particular to a kind of simple in structure and simple and easy bearing of assembling easily and disassembling, belongs to the production field of machinery product middle (center) bearing.

Background technique

Bearing is used very extensive in industrial production and actual life, all can use bearing in nearly all product that relates to rotation, such as the various lathes in the commercial Application, motor etc., the fan that we contacted in the actual life, the motor in the air-conditioning etc. all need to use bearing.The main structure of bearing is presented as: comprise external axle sleeve, internal axle sleeve and rolling element, rolling element is sleeved between external axle sleeve and the internal axle sleeve, is used to make the rolling friction that produces the frictional force minimum between external axle sleeve and the internal axle sleeve; During application, fix whole bearing, under other dynamic action, make the rotation of internal axle sleeve or external axle sleeve then, reach required purpose by the fixing position of external axle sleeve or internal axle sleeve.External axle sleeve, internal axle sleeve and the rolling element of existing bearing generally all are metallic material (based on firm material), rolling element is ball, because to the process equipment that external axle sleeve, internal axle sleeve and ball are fixed and mutual spacing needs are comparatively complicated, so existing bearing all is to process fully just to be passed to market after as a whole in factory, common people can't disassemble it, so as long as certain part is damaged, just whole bearing replacing can only be fallen, increase the cost in the using process.Because the assembling to each parts also needs than complex apparatus and technology, so cost of production is also higher.So, be not that there is obvious defects in existing bearing in the very high application (such as rolling shutter door) to usage requirement, promptly produce and user cost higher.

Summary of the invention

The purpose of this utility model just is to provide in order to address the above problem a kind of simple in structure and simple and easy bearing of assembling easily and disassembling, and the production of this bearing and user cost are all lower.

The utility model is achieved through the following technical solutions above-mentioned purpose:

The utility model comprises external axle sleeve and internal axle sleeve, the external axle sleeve overcoat is installed on the internal axle sleeve, its innovation part is, with Vertical direction is the axial direction of described external axle sleeve and internal axle sleeve, described external axle sleeve is made up of the lower cover and the loam cake of mutual fastening, the center of lower cover and loam cake is respectively arranged with equirotal hole, and the slightly larger in diameter in hole is in the external diameter of internal axle sleeve, and the hole of lower cover and loam cake is passed at the two ends of internal axle sleeve respectively; Be surrounded with the evagination flip sleeve on the outer circle wall of internal axle sleeve, the external diameter of evagination flip sleeve is slightly less than the internal diameter of lower cover; The evagination flip sleeve is positioned at lower cover, and the height of evagination flip sleeve and the height of lower cover are roughly the same.

During installation, the Kong Bingrang evagination flip sleeve that a first end with internal axle sleeve passes the lower cover center contacts with the inner bottom surface of lower cover, installs lubricant oil then in lower cover additional, loam cake is buckled in down to cover at last, and the assembling of whole bearing has just been finished.Pass through the scrolling realization relative rotary motion of evagination flip sleeve between external axle sleeve and the internal axle sleeve, pressure between external axle sleeve and internal axle sleeve (will inevitably produce pressure in the application) is not very big and rotational speed is not (in using as rolling shutter door under the very fast situation, the gravity of rolling shutter door can become the pressure between external axle sleeve and the internal axle sleeve, the rotational speed of its requirement is little), also can make relative rotary motion at an easy rate between external axle sleeve and the internal axle sleeve.During application that one of external axle sleeve or internal axle sleeve is fixing, internal axle sleeve or external axle sleeve just become rotatable carrier so, couple together it and the parts of needs rotation just passable.

The beneficial effects of the utility model are:

Because parts of the present utility model are few and simple, each parts all can be assembled and be disassembled easily, gets final product so only need produce each parts when producing, and need not finish assembling procedure, has reduced cost of production; In use, if certain parts is impaired, the impaired parts of replacing are assembled and are got final product after then the utility model can being disassembled, and have saved user cost; To sum up, to be highly suitable for the pressure between external axle sleeve and the internal axle sleeve be not very big to the utility model and rotational speed is not very fast situation.In addition, owing to there is upper and lower cover to seal,, can prevent that also dust from entering, and helps prolonging the life-span of product simultaneously so outward appearance of the present utility model is more attractive in appearance.
