Description

A kind of applanation bearing

Technical field

The utility model relates to field of bearings to be mainly used in automotive suspension more particularly, to a kind of applanation bearing On damper, bearing automobile car body weight and car assisted steering.

Background technique

The linear motion bearing form of early stage exactly places row's rod under row's skid plate.Modern linear motion bearing Same working principle is used, only replaces roller with ball sometimes.Simplest swivel bearing is axle sleeve bearing, it is only It is the bushing being clipped between wheel and wheel shaft.This design is then scrolled bearing substitution, exactly with many cylindrical Roller substitutes original bushing, and each rolling element is just as an individual wheel.

On an ancient Roman's ship for being built in B.C. 40 years of Italian nanometer lake discovery, it was found that the ball of early stage The example of bearing: a wooden ball bearing is for supporting rotating table top.It is said that Lie Angnaduo Leonardo da Vinci was on a left side in 1500 The right side once carried out description to a kind of ball bearing.In the various immature factors of ball bearing, it is important that have be exactly ball it Between can collide, cause additional friction.But this phenomenon can be prevented by the way that ball is put into small cage one by one.17 generation It records, Galileo did earliest description to the ball bearing of " cage mounted ball ".The C. watts of Lip river at 17th century end, Britain manufactures and designs ball axis It holds, and the fertile patent for thinking to obtain ball bearing of P. on probation and Britain on postal car.It puts into earliest practical with retainer Rolling bearing be clock and watchmaker John Harry be inferior to 1760 for production H3 chronoscope and invent.18 end of the centurys Germany H.R. hertz delivers the paper about ball bearing contact stress.On the basis of hertz achievement, German R. applies Trebek, auspicious A. pa nurse Glenn of allusion quotation et al. has carried out a large amount of test, makes to the design theory and Calculation of Fatigue Life that develop rolling bearing Contribution.Then, the N.P. Dinko Petrov application newton law of viscosity of Russia calculates bearing friction.First about ball track Patent is that the gloomy Philips of Karma irrigates grace in acquisition in 1794.

1883, Friedrich Fei Sheer, which is proposed, ground that size is identical, circularity is quasi- using suitable production machine The opinion of true steel ball has established the basis of bearing industry.

Bearing: for determining rotary shaft and other parts relative motion position, the components of bearing or guiding role are played.It It is that component that is fixed and reducing load coefficient of friction is played in mechanical transmission course.It may also be said that when other parts on axis that When this generates relative motion, for reducing the coefficient of friction in power transmission process and the parts of holding shaft center fixation.

Existing automotive suspension pres planes bearing, since structure is limited, sealing, dust-proof, waterproof and other effects are poor, determine Position, guide frame limitation are easy to appear the failures such as damaged and steering abnormal sound during the motion.Therefore, it is necessary to its carry out Change.

Summary of the invention

Good, steel ball slow-roll stabilization plane pressure that the technical problem to be solved by the utility model is to provide a kind of sealing effects Power bearing.

Technical solution adopted by the utility model to solve the above technical problems is as follows: a kind of applanation bearing, including it is outer Circle, lower cover, lower railway, retainer, upper rail and upper cover, the upper cover and lower cover clamping, the outer ring are connect with lower cover, The lower railway, upper rail are arranged between upper cover and lower cover, and the lower railway is embedded in lower cover, the upper rail It is embedded in upper cover, the retainer is arranged between lower railway and upper rail, and movable steel is equipped in the retainer Pearl, the outer ring are equipped with several grooves by preset space length setting, and the spacing between two neighboring groove is consistent.

Compared with prior art, good, steel ball slow-roll stabilization that the utility model has the advantage of sealing effects, rotation is normal, No cracking has no abnormal sound, without catching phenomenon, is favored by client very much.
