Abstract
The utility model belongs to bearing technique. A bearing external ring 1 of the disclosed double half-external ring nonstandard self-aligning roller bearing is in a double half ring involution structure, the axial length of an internal ring 2 is larger than that of the external ring 1, and the internal ring 1 is provided with a positioning hole 5; a retainer 4 is in a double-row pocket hole structure and is provided with two rows of pocket holes 6 in the axial direction, and rollers 3 are arranged in the pocket hole, and each row of rollers 3 is in peripheral distribution, and a row of rollers is staggered with another row of rollers. The bearing arrangement disclosed by the utility model has the advantage of the prior roller bearing, the structure improvement on the retainer can make the roller rotary adaptability largely increased, cost is reduced, and the service life of the bearing is prolonged.
Description
Affiliated technical field
The utility model belongs to bearing technology, mainly proposes a kind of non-standard self-aligning roller bearing with double semi outer rings.
Background technique
The purposes wide range of the non-standard self-aligning roller bearing with double semi outer rings in using now is used for sprocket wheel conveying equipment and many strong points back shaft in a large number.Many import equipment are also used the bearing of this kind structure, as are used for the little wall revolution of Italian product equipment Kang Disi electric furnace ultrasound velocity carbon oxygen lance bearing.The comparatively special and normal selfaligning roller bearing of the structure of this bearing has very big difference.Its outer ring is two half-turn structures, has guaranteed the convenience of assembling, and two outer rings are involutory during assembling, and the play of bearing guarantees that by the axial internal clearance of adjusting the outer ring inner ring exceeds the outer ring both ends of the surface, and promptly the inner ring axial length is greater than the axial length of outer ring.Two positioning holes of inner ring are 90 ° of distributions, inner ring links into an integrated entity by attachment bolt and axle, so both made things convenient for installation (axle and inner ring internal diameter are Spielpassung, are interference fit generally speaking), guaranteed again that axle and inner ring did not produce slide relative when rotated.But the retainer of existing this kind bearing all is a punching press steel plate basket-shaped structure, and its cost is higher, and the retainer of this structure makes that the revolution flexibility of roller is lower, and makes the life-span of bearing reduce.
Summary of the invention
The purpose of this utility model promptly is to propose a kind of non-standard self-aligning roller bearing with double semi outer rings, by the improvement to its retainer, improves the revolution flexibility of roller, improves bearing working life and cost is reduced.
The utility model is finished the technological scheme that its invention task takes: the outer ring of its bearing is the involutory structure of two half rings, and the inner ring axial length has positioning hole greater than the axial length of outer ring on the inner ring; The improvement structure is: adopt the retainer of double pocket hole structure, promptly retainer axially has two row pocket holes and in the pocket hole roller is installed, and every row roller is circle distribution and relative another row roller of a row roller is interspersed.
The bearing structure that the utility model proposes has the advantage of existing roller bearing, and it can make the revolution flexibility of roller improve a lot the working life of having reduced cost and having improved bearing to the architecture advances of retainer.

Among the figure, 1, the outer ring, 2, inner ring, 3, roller, 4, retainer, 5, positioning hole, 6, the pocket hole, 7, beam, 8, bottom girder.
Embodiment
The accompanying drawing that provides is in conjunction with the embodiments further specified its structure:
Shown in accompanying drawing 1,2, the outer ring 1 of bearing is two half-turn structures, and two outer rings are involutory during assembling.Inner ring 2 exceeds the outer ring both ends of the surface, and promptly the axial length of inner ring 2 is greater than the axial length of outer ring 1.Have two positioning holes 5 on the inner ring 2 and two positioning holes are 90 ° of distributions.Retainer 4 is double pocket hole structure, and promptly retainer axially has two row's pocket holes 6 and roller 3 is installed in the pocket hole, and every row roller is circle distribution and relative another row roller of a row roller is staggered.Retainer pocket hole 6 is close with the roller shape, is better guide rolls, and the retainer bottom girder 8 between two row's pocket holes is thicker, and intensity and rigidity are better, and the beam 7 between retainer pocket hole and the pocket hole plays the effect of guide rolls.
Claims (1)
1, a kind of non-standard self-aligning roller bearing with double semi outer rings, the outer ring of its bearing (1) are two involutory structures of half-turn, and the axial length of inner ring (2) has positioning hole (5) greater than the axial length of outer ring (1) on the inner ring (1); It is characterized in that: retainer (4) is double pocket hole structure, and retainer (4) axially has two row pocket holes (6) and roller (3) is installed in the pocket hole, and every row roller (3) is circle distribution and relative another row roller of a row roller is interspersed.
