Description
Technical field
The present invention relates to field of bearings, more particularly to a kind of high strength and low friction torque Double-row-roller bearing.
Background technology
At present, taper roll bearing is a kind of mechanical basic part of standard, and general part.The appearance and size of each model
It is standard, the size of its each part is also what is be basically unchanged.Theoretically, if the bearing appearance and size of same model,
Rated load and limit speed meet requirement, are used equally for various operating modes.However, requirement of some special operation conditions to bearing
It is or otherwise varied.For example, truck main reducing gear of drive axle main cone taper roll bearing (inner bearing) is born very because of it
Big axial load, is often being overloaded, under the operating mode of road conditions difference using general bearing, is be easy to causeing bearing inner race large-flange and break
Split, bearing damage.In addition, common shaft, which honours reduction moment of friction, does not also take special measure, therefore, to the energy saving of automobile
With environmental requirement it is higher and higher in the case of, the moment of friction for reducing bearing is also very important.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of high strength and low friction torque Double-row-roller bearing, and solution is never
The problem of bearing very big axial load.
The technical solution that the present invention solves above-mentioned technical problem is as follows：A kind of high strength and low friction torque Double-row-roller axis
Hold, including outer ring, inner ring, be located between them to play a supportive role and realize and the multiple rollers rotated against and separate and draw
The retainer of guide roller movement, the roller can be rolled by the retainer and be folded between the outer ring and the inner ring,
The roller is provided with two rows, the passage forming V-shape between the outer ring and the inner ring.
What is brought effective is：The high strength and low friction torque Double-row-roller bearing of the application, can bear two side directions
The axial stress of application, considerably increases the bearing capacity of bearing.
Further, two rows of rollers are respectively ball roller and bar shaped roller.
Further, the passage length of the ball roller side is less than the length of the bar shaped roller.
Further, the inner ring outside diameter of one side end of ball roller is less than the minimum diameter of the outer ring.
Further, the outer ring roughness value is less than 0.4 μm；The ball base surface roughness value of roller is less than 0.4 μm.
Further, the inner ring roughness is 0.25 μm, and the ball base surface roughness of roller is 0.20 μm.
Further, the appearance and size of the high strength and low friction torque Double-row-roller bearing and former general bearing and contact
Angle is identical and rated load is not less than primary standard design load.
Brief description of the drawings
Fig. 1 is a kind of cross section structure schematic diagram of high strength and low friction torque Double-row-roller bearing of the present invention.
In attached drawing, parts list represented by the reference numerals is as follows：
1st, outer ring, 2, inner ring, 3, ball roller, 4, bar shaped roller, 5, retainer.
