Description
Technical field
This utility model relates to mechanical part field, particularly relates to a kind of double-deck roller body bearing.
Background technology
Along with the development of machinery manufacturing industry, the use of machinery is more and more extensive, and bearing is as machine
The important component part of tool operating, the application at mechanical field also begins to widely, current bearing
The most also occurring in that some problems, bearing in the market is mainly made up of monolayer roller body,
When the bearing of monolayer roller body is on-stream occur that roller body damages time, may result in bearing cannot be normal
Operating, the balance and stability of monolayer rolling element is the most poor；Roller body is solid iron ball, heavier-weight,
The bearing more power of on-stream needs can be made；When bearing operation, artificial oil addition will
Occur there is more lubricating oil on roller body, cause the waste of lubricating oil.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that a kind of double-deck roller
Body bearing.
This utility model is to be achieved through the following technical solutions:
A kind of double-deck roller body bearing also includes bearing outer ring, bearing centre circle, bearing inner race, the first guarantor
Hold frame, the second retainer, the first rolling element, the second rolling element, through hole, blotter coat, described first
Rolling element array distribution is arranged on bearing outer ring and the centre position of bearing centre circle, described second rolling element
Array distribution is arranged on the centre position of bearing centre circle and bearing inner race, and on described bearing centre circle, array is opened
Being provided with multiple through hole, the two ends of described through hole are symmetrically arranged with blotter coat, and described first retainer is arranged
In the both sides, surface of the first rolling element, described second retainer is arranged on the both sides, surface of the second rolling element.
Further, the diameter of described first rolling element and the second rolling element is equal.
Further, inside described first rolling element and the second rolling element, all offer hollow hole, and empty
The diameter of central hole is the 1/2 of roller body diameter.
Further, described blotter coat is that polyurethane is made, and thickness is 1mm-2mm.
Compared with prior art, the beneficial effects of the utility model are: this utility model novel structure,
Reasonable in design, by being arranged to the roller body of bilayer, bearing can be made preferably to operate in rotation,
When the rolling element of two-layer transmits load, bearing rotating speed can be significantly improved, and the rolling element of two-layer is in
In same radial circumference plane, during transmission load, the rolling element stress of two-layer more balances, stablizes,
And when any layer rolling element damages, other one layer still is able to work on；By arrange through hole and
Blotter coat, can absorb unnecessary lubricating oil in blotter coat, and be stored in through hole middle part；
By being set to hollow ball, it is possible to reduce because bearing being set to double roller body, countershaft supporting power
Increase.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
In figure: 1-bearing outer ring；2-bearing centre circle；3-bearing inner race；40-the first retainer；41-
Second retainer；50-the first rolling element；51-the second rolling element；6-through hole；7-blotter coat；8-is hollow
Hole.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with
Drawings and Examples, are further elaborated to this utility model, it will be appreciated that this place is retouched
The specific embodiment stated, only in order to explain this utility model, is not used to limit this utility model.
As it is shown in figure 1, a kind of double-deck roller body bearing that the present embodiment provides, described double-deck roller body
Bearing includes that bearing outer ring 1, bearing centre circle 2, bearing inner race the 3, first retainer 40, second keep
Frame the 41, first rolling element the 50, second rolling element 51, through hole 6, blotter coat 7, described first rolls
Body 50 array distribution is arranged on bearing outer ring 1 and the centre position of bearing centre circle 2, and described second rolls
Body 51 array distribution is arranged on bearing centre circle 2 and the centre position of bearing inner race 3, and described first rolls
The diameter of body 50 and the second rolling element 51 is equal, and described first retainer 40 is arranged on the first rolling
The both sides, surface of kinetoplast 50, described second retainer 41 is arranged on the both sides, surface of the second rolling element 51,
By being arranged to the roller body of bilayer, the on-stream meeting of bearing can be made preferably to operate, two-layer
Rolling element transmission load time, bearing rotating speed can be significantly improved, and the rolling element of two-layer is in same
In radial circumference plane, during transmission load, the rolling element stress of two-layer more balances, stablizes, and
When any layer rolling element damages, other one layer still is able to work on, it is ensured that the stable fortune of bearing
Turn.
On described bearing centre circle 2, array offers multiple through hole 6, and the two ends of described through hole 6 are symmetrical arranged
There are blotter coat 7, described blotter coat 7 to make for polyurethane, and thickness is 1.5mm, is provided with through hole 6
With blotter coat 7, lubricating oil unnecessary in bearing can be absorbed in blotter coat 7, and be stored in through hole
6 middle parts, are possible not only to reduce the waste of lubricating oil, and make lubricating oil to be recycled.
Described first rolling element 50 and the second rolling element 51 inside all offer hollow hole 8, and hollow hole
The diameter of 8 is the 1/2 of roller body diameter, and roller body is arranged to hollow ball, it is possible to reduce because of by axle
Hold and be set to double roller body, the increase of countershaft supporting power, it is also possible to reduce production cost.
The foregoing is only preferred embodiment of the present utility model, not new in order to limit this practicality
Type, all any amendment, equivalent and improvement made within spirit of the present utility model and principle
Deng, within should be included in protection domain of the present utility model.
