Description

A kind of rolling bearing

Technical field

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

Background technique

Bearing is a kind of important spare part in contemporary machinery.Its major function is supported mechanical solid of rotation, reduces the friction factor in its movement process, and ensures its rotating accuracy.By the difference of motor element frictional property, bearing can be divided into rolling bearing and the large class of sliding bearing two.Wherein rolling bearing standardization, seriation, but its radial dimension, vibration & noise is comparatively large compared with sliding bearing, and price is also higher.Rolling bearing is generally made up of outer ring, inner ring, rolling element and retainer four part.By the shape of rolling element, rolling bearing is divided into ball bearing and the large class of roller bearing two.If the external form according to bearing can be divided into again the various forms of bearings such as cam, needle roller, ball, seated, dry type, Zi Run, universal, unidirectional, straight line, used by common mechanical product based on ball bearing.But ball bearing can be divided into ceramic bearing, industrial plastic bearing, iron shot bearing, ball bearing etc. according to the difference of its material again, use the ball bearing of unlike material according to different mechanical function and action.

Rolling bearing is that the sliding friction between the axle of running and axle bed is become rolling friction, thus reduces the mechanical component of a kind of precision of frictional loss.Rolling bearing is generally made up of inner ring, outer ring, rolling element and retainer four part, and the effect of inner ring is that the merging that matches with axle rotates together with the axis; Outer ring effect matches with bearing support, plays a supportive role; Rolling element is distributed between inner ring and outer ring by rolling element uniformly by means of retainer, and its shape size and quantity directly affect usability and the life-span of rolling bearing; Retainer can make rolling element be uniformly distributed, and prevents rolling element from coming off, and guides rolling element to rotate lubricate.Bearings with rolling contact is low friction and lubrication simply relative to the advantage of sliding contact bearing, can bear radial direction and axial load simultaneously, and stands overload and be easy to change.Compare with sliding bearing, the radial dimension of rolling bearing is comparatively large, and during high speed, the life-span is low, and after a long time use, rolling element can produce amount of heat and retainer is easy to wear for rolling bearing, thus reduces the working life of bearing.

In sum, existing rolling bearing is not well positioned to meet the application in production, needs to make improvements the working life extending bearing.

Model utility content

For overcoming the deficiencies in the prior art, the purpose of this utility model is to provide that a kind of structure is simple, the rolling bearing of long service life.

In order to solve the technical problem in background technique, the utility model provides a kind of rolling bearing, comprises outer ring, inner ring, retainer and rolling element, is provided with groove inside described outer ring, and described retainer sidewall is provided with aperture.

Further, described groove is 5 ~ 10.

Further, described groove is S shape.

Further, the cross section of described groove is semicircle.

Further, described groove two ends are connected with bearing outer ring both sides.

Further, the degree of depth of described groove is 1/7 ~ 1/3 of outer ring sidewall thickness.

Further, described groove is used for oil storage.

Particularly, described aperture is circular.

Further, described rolling element is cylindrical.

The beneficial effects of the utility model are:

(1) inside housing washer of the present utility model, groove is set, reduces the area of contact of rolling element and outer ring inwall, thus reduce force of rolling friction;

(2) S shape oil storage grooves is set inside housing washer of the present utility model, can lubricant oil be stored in groove, add oil storage amount, thus decrease the wearing and tearing between rolling element and Internal and external cycle, decrease fricative heat, extend the working life of bearing;

(3) rolling bearing retainer sidewall of the present utility model is provided with aperture, is conducive to the heat radiation of bearing roller;

(4) rolling bearing structure of the present utility model is simple, easy to implement.
