Abstract

The utility model relates to a kind of outer spherical surface double-row conical bearing, comprise set gradually outer ring, retainer and inner ring, described retainer is provided with the tapered roller of some quantity, adopt two inner rings and single outer ring structure, it is sphere outside outer ring, two inclined-planes are symmetrically formed, in the space that the inner ring on inclined-plane, outer ring and homonymy that retainer is arranged on any side is formed inside outer ring.Outer ring external diameter is designed to ball-type external diameter by the utility model, produces the situation of amount of deflection, achieve aligning function by bearing self for axle.It is high steady with rotation that the utility model has taken into account tapered roller bearing rotating speed, shakes little feature, can realize self-aligning again, achieve the object using tapered roller bearing on major axis, expanded the applicable situation of tapered roller bearing.

Description

Outer spherical surface double-row conical bearing
Technical field
The utility model relates to technical field of bearings, the double-row conical bearing of specifically a kind of improvement.
Background technique
Current most tapered roller bearing, is used in when minor axis or axle operationally do not produce amount of deflection and uses.Easily produce the occasion of amount of deflection at major axis or axle, because tapered roller bearing does not have self-aligning function, can not use tapered roller bearing, the use like this for tapered roller bearing has just had certain narrow limitation.
Summary of the invention
The technical problems to be solved in the utility model is to provide one and remains height rotating speed when tapered roller bearing uses, the feature that running accuracy is high, meet again when axle generation amount of deflection simultaneously, the outer spherical surface double-row conical bearing of self-aligning function can be carried out by bearing self.
For solving above technical problem, the technical solution adopted in the utility model is:
A kind of outer spherical surface double-row conical bearing, comprise set gradually outer ring, retainer and inner ring, described retainer is provided with the tapered roller of some quantity, adopt two inner rings and single outer ring structure, it is sphere outside outer ring, two inclined-planes are symmetrically formed, in the space that the inner ring on inclined-plane, outer ring and homonymy that retainer is arranged on any side is formed inside outer ring.
Outer ring external diameter is designed to ball-type external diameter by the utility model, produces the situation of amount of deflection, achieve aligning function by bearing self for axle.It is high steady with rotation that the utility model has taken into account tapered roller bearing rotating speed, shakes little feature, can realize self-aligning again, achieve the object using tapered roller bearing on major axis, expanded the applicable situation of tapered roller bearing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1-outer ring, 2-retainer, 3-inner ring, 4-tapered roller.
Embodiment
In order to make those skilled in the art better understand the utility model, below in conjunction with accompanying drawing, explanation clear, complete is further done to the utility model.
Outer spherical surface double-row conical bearing shown in Fig. 1, comprise set gradually outer ring 1, retainer 2 and inner ring 3, described retainer 2 is provided with the tapered roller 4 of some quantity.This bearing adopts inner ring two pieces, and outer ring is single outer ring, forms two inner rings and single outer ring structure, is sphere, is symmetrically formed two inclined-planes inside outer ring 1 outside outer ring 1.Retainer punching press iron is protected, and in the space that the inner ring 3 on inclined-plane, outer ring and homonymy that retainer 2 is arranged on any side is formed, symmetrically arrange two groups of retainers 2, tapered roller 4 is arranged in retainer 2.
The claimed scope of the utility model is not limited to above embodiment; to those skilled in the art; the utility model can have various deformation and change, all in design of the present utility model and any amendment, the improvement done within principle be equal to replacement and all should be included within protection domain of the present utility model.
