Description
Technical field
The utility model relates to piston bearing technical field, specifically a kind of piston bearing with dust guard.
Background technique
Bearing is a kind of important spare part in contemporary mechanical equipment.Its major function is to support mechanical rotary body, is reduced
Coefficient of friction in its motion process, and guarantee its rotating accuracy.The linear motion bearing form of early stage is exactly in row's skid plate
One row's rod of lower placement.Modern linear motion bearing uses same working principle, only replaces roller with ball sometimes.
Simplest swivel bearing is axle sleeve bearing, it is the bushing being clipped between wheel and wheel shaft.It is this to design then quilt
Rolling bearing substitution exactly substitutes original bushing with many cylindrical rollers, and each rolling element is just as an individual vehicle
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 bearing of early stage
Example: a wooden ball bearing is for supporting rotating table top.It is said that Lie Angnaduo Leonardo da Vinci at 1500 or so once
Through carrying out description to a kind of ball bearing.In the various immature factors of ball bearing, it is important that having is exactly meeting between ball
It collides, causes additional friction.But this phenomenon can be prevented by the way that ball is put into small cage one by one.The 17th century,
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 bearing,
And the fertile patent for thinking to obtain ball bearing of P. on probation and Britain on postal car.The practical rolling with retainer is put into earliest
Dynamic bearing is that clock and watchmaker John Harry is inferior to invent for production H3 chronoscope for 1760.The H.R. of 18 end of the centurys Germany
Hertz delivers the paper about ball bearing contact stress.On the basis of hertz achievement, German R. applies Trebek, Sweden
A. pa nurse Glenn et al. has carried out a large amount of test, has made tribute to the design theory and Calculation of Fatigue Life that develop rolling bearing
It offers.Then, the N.P. Dinko Petrov of Russia calculates bearing friction using newton law of viscosity.First patent about ball track
It is that the gloomy Philips of Karma irrigates grace in acquisition in 1794.1883, Friedrich Fei Sheer was proposed using suitable
Production machine grind that size is identical, the opinion of the accurate steel ball of circularity, established the basis of bearing industry.The O. Reynolds of Britain
Mathematical analysis has been carried out to the discovery of Bristol, Reynolds equation has been derived, the basis of hydrldynamic pressure lubrication theory has been established from this.
At present about the piston bearing with dust guard there are still not in place, such as: inconvenient, dust-proof effect
Difference, leakproofness are poor.
