Abstract
The invention discloses a non-standard self-aligning roller bearing with double semi outer rings, which is provided with an outer ring (1) and an inner ring (2); the outer ring (1) has a double semi-ring structure; a retainer (6) is arranged between the outer ring (1) and the inner ring (2); and two groups of rollers (4) are arranged in the retainer (6). The non-standard self-aligning roller bearing is characterized in that: the retainer (6) is provided with two rows of pockets axially; the rollers (4) are arranged in the pockets; and the rollers are distributed circumferentially, and one row of rollers are arranged in a staggered way relative to the other row of rollers. The retainer adopts a double-row pocket structure, can accurately guide the rollers, ensures stable operation of the bearing, and is suitable for high-speed operation; and the pockets not only can ensure that the rollers do not glide off after assembly, but also improve the flexibility of the rollers, can meet the requirements of enlarging the roller size and increasing the roller number, strengthen the bearing capacity of the bearing, and prolong the service life of the bearing. The structure facilitates adding lubricating grease, and the lubricating grease has good lubricating effect, reduces noise, and reduces bearing wear and overheating; and the bearing has easy processing and low manufacturing cost.
Description
Technical field:
The present invention relates to a kind of bearing, especially 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 is guaranteed by the width of adjusting the outer ring.So both made things convenient for installation, 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 reduce the working life of bearing.
Summary of the invention:
The present invention is directed to the above-mentioned deficiency of prior art, provide a kind of with low cost, flexibility is good, the non-standard self-aligning roller bearing with double semi outer rings that working life is long.
Technical solution of the present invention is: a kind of non-standard self-aligning roller bearing with double semi outer rings, be provided with outer ring and inner ring, the outer ring is two half-turn structures, between outer ring and inner ring, be provided with retainer, two groups of rollers are installed in the retainer, retainer axially has two row's pocket holes, and roller is installed in the pocket hole, and every row roller is circle distribution and relative another row roller of a row roller is staggered.
Described pocket hole is close with the roller shape, better guide rolls.
Retainer of the present invention adopts double pocket hole structure, and accurately guide rolls guarantees that bearing operation is steady, is applicable to run up; The pocket hole both can guarantee not draw after roller is packed into to be taken off, and has improved its flexibility again, and can satisfy increase roller size, increases the demand of roller quantity, has strengthened the bearing capacity of bearing, has prolonged its working life.The convenient lubricating grease that adds of this structure, lubrication effect is good, reduces noise, reduces bearing wear and overheated; Be easy to processing, cheap for manufacturing cost.

Fig. 1 is a structural representation of the present invention.
Fig. 2 is the structural representation of outer ring of the present invention.
Fig. 3 is the structural representation of inner ring of the present invention.
Fig. 4 is the structural representation of retainer of the present invention.
Fig. 5 is the A-A sectional view of Fig. 4.
Embodiment:
Further specify the specific embodiment of the present invention below in conjunction with accompanying drawing.
Shown in Fig. 1 ~ 5, a kind of non-standard self-aligning roller bearing with double semi outer rings is provided with outer ring 1 and inner ring 2, and outer ring 1 is two half-turn structures, and two outer rings are involutory during assembling.In the outer ring 1 and 2 of inner rings be provided with retainer 6, two groups of rollers 4 are installed in the retainer 6, retainer 6 axially has two row pocket holes, roller 4 is installed in the pocket hole, every row roller be circle distribution and a row roller relatively another row roller be staggered.Described pocket hole is close with the roller shape, better guide rolls.Retainer bottom girder between two row's pocket holes is thicker, and intensity and rigidity are better, and the beam between retainer pocket hole and the pocket hole plays the effect of guide rolls.
Claims (2)
