Description
Technical field
The utility model relates to field of bearings, particularly relates to a kind of non-symmetry structure selfaligning roller bearing.
Background technique
Conventional bearings model is biserial symmetric form selfaligning roller bearing, can bear the axial force of radial direction and both direction, and the ability that two row rollers bear thrust load is identical.
It is the same that biserial symmetric form selfaligning roller bearing often arranges the unidirectional load ability that can bear.And the operating mode of bulk cement carrier main transmission gearbox output shaft is while bear larger axial force, another side bears little axial force.Therefore, the bearing roller and the raceway that bear larger axial force one end easily occur that early fatigue peels off, and do not reach requirement projected life.
Model utility content
The technical problem that the utility model mainly solves is to provide a kind of non-symmetry structure selfaligning roller bearing, can bear larger unidirectional load having under identical appearance size condition, more adapts to the operating mode of concrete mixer can body main transmission box output terminal bearing.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: provide a kind of non-symmetry structure selfaligning roller bearing, comprise: outer ring, inner ring, roller and retainer, described inner ring is arranged in outer ring, a cavity volume is formed between inner ring and outer ring, the retainer of the asymmetric arrangement of two row is arranged with: retainer A and retainer B in described cavity volume, the size of described retainer A is greater than the size of retainer B, or the size of retainer B is greater than the size of retainer A, embed respectively in described retainer A and retainer B and two row rollers are installed: roller C and roller D, the size of this two row roller is corresponding with the size of described two row retainers.
Preferably, the external diameter of described outer ring and the inner radius of inner ring are provided with rounded corner.
Preferably, the material of described retainer A and retainer B is: PA66-GF25.
Preferably, described roller C and roller D is of a size of GCr15.
Preferably, described roller C and roller D adopts electroslag remelting process to make.
The beneficial effects of the utility model are: the symmetrical selfaligning roller bearing of conventional biserial single roller energy bearing load is 291.6KN, and the utility model large roller end energy bearing load is 346KN.Under concrete mixer can body main transmission box output terminal working condition, the working life of non-symmetry structure selfaligning roller bearing is the twice of conventional bearings.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model non-symmetry structure selfaligning roller bearing one preferred embodiment;
In accompanying drawing, the mark of each parts is as follows: 1, outer ring, and 2, inner ring, 3, retainer A, 4, retainer B, 5, roller C, 6, roller D.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.
Refer to Fig. 1, the utility model is embodiment comprise:
A kind of non-symmetry structure selfaligning roller bearing, comprise: outer ring 1, inner ring 2, roller and retainer, described inner ring 2 is arranged in outer ring 1, a cavity volume is formed between inner ring 2 and outer ring 1, the retainer of the asymmetric arrangement of two row is arranged with: retainer A3 and retainer B4 in described cavity volume, the size of described retainer A3 is greater than the size of retainer B4, or the size of retainer B4 is greater than the size of retainer A3, embed respectively in described retainer A3 and retainer B4 and two row rollers are installed: roller C5 and roller D6, the size of this two row roller is corresponding with the size of described two row retainers, the utility model adopts non-symmetry structure, i.e. row's large roller, one row's small roller.Large roller end mainly bears the load of cement can body, and small roller end mainly plays support and aligning effect.
The external diameter of described outer ring 1 and the inner radius of inner ring 2 are provided with rounded corner, avoid bearing seamed edge to hurt workman, improve the safety coefficient of bearing.
The material of described retainer A3 and retainer B4 is: PA66-GF25, has good linear expansion coeffcient.
Described roller C5 and roller D6 is of a size of GCr15, has higher hardness, uniform tissue, good wear resistance, high contact fatigue property.
Described roller C5 and roller D6 adopt electroslag remelting process to make, the steel ingot of clean even tissue densification can be obtained, purity is high, sulfur-bearing is low, sonims is few, surface of steel ingot is smooth, clean even compact, metallographic structure and chemical composition even.
The utility model is arranged on the output terminal of concrete mixer can body main transmission gearbox, and bearing is that inner ring rotates.Bearing inner race and axle are interference fit, bearing outer ring and gear-box bore Spielpassung.Bearing large roller end towards concrete mixer can body side, with bear can body weight produce large axial thrust load.Small roller end, towards gear-box side, only plays support corrective action.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model specification and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
