Background technology
China is one of country of earliest invention rolling bearing in the world, in Chinese Ancient Books, the structure on axle bearing
It makes early on the books.From archaeology historical relic in terms of data, the most ancient bearing with modern times rolling bearing structure blank of China goes out
Now in modern Shanxi Province's Yongji County Xue Jiaya villages of B.C. 221~207 years (Qin Dynasty).After founding of New, this century is particularly
Since the seventies, under the powerful promotion of reform and opening-up, bearing industry enters a brand-new high-quality fast-developing period
At 17th century end, C. watts of Lip river of Britain manufactures and designs ball bearing, and P. on probation and Britain irrigates think of acquirement on postal car
The patent of ball bearing.The H.R. hertz of 18 end of the centurys Germany delivers the paper on ball bearing contact stress.It is achieved in hertz
On the basis of, German R. applies Trebek, the A. pa nurse Glenns et al. of Sweden have carried out substantial amounts of experiment, to developing the axis of rolling
The design theory and Calculation of Fatigue Life held contribute.Then, the N.P. Dinko Petrov application newton law of viscosities of Russia
Calculate bearing friction.The O. Reynolds of Britain has carried out mathematical analysis to the discovery of Bristol, is derived Reynolds equation, is established from this
The basis of hydrldynamic pressure lubrication theory.It is founding the state over 50 years, Chinese bearing work obtains remarkable achievement already.
Current Biserial cylindrical roller bearing, rigidity is small, bearing capacity is small and is deformed after by load big.
Therefore, a kind of Biserial cylindrical roller bearing is invented to be very necessary.
The content of the invention
It is current to solve to propose in above-mentioned background technology it is an object of the invention to provide a kind of Biserial cylindrical roller bearing
Biserial cylindrical roller bearing, rigidity it is small, bearing capacity is small and the problem of big is deformed after by load.
To achieve the above object, the present invention provides following technical solution：A kind of Biserial cylindrical roller bearing, including bearing sheet
Body, the first retainer, the first end cap, the first outer ring, the second outer ring, the first inner ring, the second end cap, the second inner ring, the first cylinder
Roller, the second cylindrical roller and the second retainer, the bearing body include the first outer ring, the second outer ring, the first inner ring and the
Two inner rings；The first retainer is provided between first inner ring and the first outer ring；First is provided on first retainer
Cylindrical roller；The second retainer is provided between second inner ring and the second outer ring；Is provided on second retainer
Two cylindrical rollers；One end of first inner ring and the first outer ring is fixed with the first end cap；Second inner ring and the second outer ring
One end be fixed with the second end cap.
Further, the both sides of first outer ring are both provided with rib.
Further, the both sides of second outer ring are both provided with rib.
Further, the both sides of first inner ring are both provided with rib.
Further, the both sides of second inner ring are both provided with rib.
The technique effect and advantage of the present invention：The Biserial cylindrical roller bearing, by set the first outer ring, the second outer ring,
First inner ring and the second inner ring are combined into, and set between the first inner ring and the first outer ring the first retainer and
First cylindrical roller on one retainer is set, and the second retainer, Yi Ji are set between the second inner ring and the second outer ring
The second cylindrical roller is set to be combined into Biserial cylindrical roller bearing on second retainer so that rigidity is big, large carrying capacity and by
It is deformed after load small.
