Abstract
The utility model discloses a kind of free from ball bearing, including upper cover, side washer, plain washer, lower cover and rubber parts, upper cover, lower cover are annular in shape, upper cover and lower cover snapping, side washer and plain washer are arranged between upper cover and lower cover, and side washer is cylindrical, the flaky circular ring structure of plain washer, plain washer and side washer are orthogonal, and rubber parts is embedded in lower cover, and upper tops are equipped with several through-holes by preset space length along its circumference.The utility model rotation is normal, and no cracking has no abnormal sound, without catching phenomenon, is favored by client very much, rubber parts is additionally arranged in lower cover, so that the damping noise reduction effect of the utility model is more preferable.
Description
Technical field
The utility model relates to technical field of bearings, more particularly, to a kind of free from ball bearing.
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 of Russia calculates bearing friction using newton law of viscosity.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
The technical problem to be solved by the utility model is to provide a kind of rotations of product normally, and no cracking has no abnormal sound, without card
The free from ball bearing of stagnant phenomenon.
Technical solution adopted by the utility model to solve the above technical problems is as follows: a kind of free from ball bearing, including upper cover,
Side washer, plain washer, lower cover and rubber parts, the upper cover, lower cover are annular in shape, the upper cover and lower cover snapping, institute
The side washer and plain washer stated are arranged between upper cover and lower cover, and the side washer is cylindrical, and the plain washer is in
The circular ring structure of sheet, the plain washer and side washer are orthogonal, and the rubber parts is embedded in lower cover, and described is upper
Tops are equipped with several through-holes by preset space length along its circumference.
It is further improved as the utility model, the upper cover external diametrical extent is 108mm ~ 109mm, in the upper cover
Diameter periphery is 89mm ~ 90mm.
Compared with prior art, the utility model has the advantage of rotation is normal, no cracking has no abnormal sound, without catching phenomenon,
Favored by client very much, rubber parts is additionally arranged in lower cover, so that the damping noise reduction effect of the utility model is more preferable.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is schematic cross-section at I-I in Fig. 1；
Fig. 3 is enlarged diagram at B in Fig. 2.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only to explain this
Utility model is not used to limit the utility model.
It is as shown in Figure 1 to Figure 3: a kind of free from ball bearing, including upper cover 1, side washer 2, plain washer 3, lower cover 4 and rubber parts
5, upper cover 1, lower cover 4 are annular in shape, and upper cover 1 and 4 snapping of lower cover, side washer 2 and plain washer 3 are arranged at upper cover 1 and lower cover 4
Between, side washer 2 is cylindrical, and the flaky circular ring structure of plain washer 3, plain washer 3 and side washer 2 are orthogonal, rubber parts 5
It is embedded in lower cover 4,1 top of upper cover is equipped with several through-holes 6 by preset space length along its circumference.
1 external diametrical extent of upper cover is 108mm ~ 109mm, and 1 internal diameter periphery of upper cover is 89mm ~ 90mm.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model
Protection scope within.
