Description

A kind of low elastic force radial direction buffering bearing

[technical field]

The utility model relates to the technical field of bearing, particularly a kind of technical field of low elastic force radial direction buffering bearing.

[background technique]

Early stage linear motion bearing form is exactly place row's rod under row's skid plate.Modern linear motion bearing uses same working principle, only sometimes replaces roller with ball.The simplest swivel bearing is axle sleeve bearing, and it is a lining being clipped between wheel and wheel shaft.This design is scrolled bearing subsequently and substitutes, and substitutes original lining exactly with a lot of columniform roller, and each rolling element is just as an independent wheel.Italy how rice lake one of finding be built on ancient Roman's ship of B.C. 40 years, find the example of early stage ball bearing: a wooden ball bearing is used to support rotating table top.It is said that Lie Angnaduo Leonardo da Vinci once carried out description to a kind of ball bearing at about 1500.In the various immature factor of ball bearing, there is the very important point to be exactly can collide between ball, cause extra friction.But this phenomenon can be prevented by ball being put into little cage one by one.The 17th century, the ball bearing of Galileo to " cage mounted ball " did description the earliest.17th century end, C. watt of Lip river of Britain manufactures and designs ball bearing, and to be contained on postal car P. that is on probation and Britain and to irrigate the patent that think of obtains ball bearing.Dropping into the practical rolling bearing with retainer is the earliest that clock and watchmaker John Harry is inferior to 1760 for making H3 chronoscope and invents.18 the end of the century Germany hertz deliver paper about ball bearing contact stress.On the basis of hertz achievement, the R. of Germany executes Trebek, the people such as A. handkerchief nurse Glenn of Sweden has carried out a large amount of tests, contributes to the design theory of development rolling bearing and Calculation of Fatigue Life.Subsequently, the Dinko Petrov application newton law of viscosity calculation bearing friction of Russia.First patent about ball track is that the gloomy Philips of Karma irrigates grace and obtained in 1794.

1883, Friedrich Fei Sheer proposed and uses that suitable production machine grinds that size is identical, the opinion of circularity steel ball accurately, has established the basis of bearing industry.The Reynolds of Britain has carried out mathematical analysis to the discovery of Bristol, is derived reynolds equation, has from then on established the basis of hydrldynamic pressure lubrication theory.

Bearing mainly comprises inner ring, outer ring, rolling element steel ball or roller and retainer, the shock-resistant ability of traditional bearing is more weak, not there is buffer function, so bearing is very high to the hardness requirement of material in application process, not so bearing inside after being subject to hard hit just there will be indenture, has a strong impact on the life-span of bearing, a kind of bearing with certain pooling feature of market demand, certain shock can be resisted, extend the life-span of bearing.

[model utility content]

The purpose of this utility model solves the problems of the prior art exactly, propose a kind of low elastic force radial direction buffering bearing, bearing can be made to have certain radial elastic, the active force of hard hit can be cushioned, avoid indenture appears in parts, the life-span of bearing can be extended.

For achieving the above object, the utility model proposes a kind of low elastic force radial direction buffering bearing, comprise outer ring, inner ring, roller and retainer, the both sides of described outer ring are provided with outer ring baffle ring, be provided with roller, be provided with inner ring inside outer ring between the baffle ring of described outer ring, the both sides of described inner ring are respectively arranged with the low anti-decylization of inner ring and the high anti-decylization of inner ring, be provided with retainer between described inner ring and outer ring, described roller is embedded in retainer, is provided with elastic force hole in roller.

As preferably, the width of the low anti-decylization of described inner ring is less than the width of the high anti-decylization of inner ring.

As preferably, cylindrically, the wall thickness of roller is 2 ~ 5mm to described roller.

The beneficial effects of the utility model: the utility model is by being applied on bearing by outer ring, inner ring, roller and retainer, roller arranges elastic force hole, bearing can be made to have certain radial elastic, the active force of hard hit can be cushioned, avoid indenture appears in parts, the life-span of bearing can be extended.

Feature of the present utility model and advantage will be described in detail by reference to the accompanying drawings by embodiment.

[accompanying drawing explanation]

Fig. 1 is the main pseudosection of a kind of low elastic force radial direction buffering bearing of the utility model;

Fig. 2 is the left view of a kind of low elastic force radial direction buffering bearing of the utility model.

In figure: 2-outer ring, 21-outer ring baffle ring, 3-inner ring, the low anti-decylization of 31-inner ring, the high anti-decylization of 32-inner ring, 4-roller, 41-elastic force hole, 5-retainer.

[embodiment]

Consult Fig. 1 and Fig. 2, a kind of low elastic force radial direction buffering bearing of the utility model, comprise outer ring 2, inner ring 3, roller 4 and retainer 5, the both sides of described outer ring 2 are provided with outer ring baffle ring 21, be provided with roller 4, be provided with inner ring 3 inside outer ring 2 between described outer ring baffle ring 21, the both sides of described inner ring 3 are respectively arranged with the low anti-decylization 31 of inner ring and the high anti-decylization 32 of inner ring, be provided with retainer 5 between described inner ring 3 and outer ring 2, described roller 4 is embedded in retainer 5, is provided with elastic force hole 41 in roller 4.The width of the low anti-decylization 31 of described inner ring is less than the width of the high anti-decylization 32 of inner ring.Cylindrically, the wall thickness of roller 4 is 2 ~ 5mm to described roller 4.

A kind of low elastic force radial direction buffering bearing of the utility model, by outer ring 2, inner ring 3, roller 4 and retainer 5 are applied on bearing, roller 4 arranges elastic force hole 41, bearing can be made to have certain radial elastic, the active force of hard hit can be cushioned, avoid indenture appears in parts, the life-span of bearing can be extended.

Above-described embodiment is to explanation of the present utility model, is not to restriction of the present utility model, anyly all belongs to protection domain of the present utility model to the scheme after the utility model simple transformation.
