Abstract
The utility model provides a tapered roller bearing suitable for high-speed rotation, includes inner circle, outer lane, a plurality of hollow roller, holder and circlip, characterized by the outer conical surface of inner circle on and be corresponding tapered roller way on the outer lane inner wall respectively, the inner circle is equipped with single flange, the holder for with tapered roller way assorted conical body, be provided with a plurality of roller pocket holes respectively on the holder, be provided with the oil through hole respectively on the both ends face in a plurality of roller pocket holes, a plurality of hollow roller install respectively in a plurality of roller pocket holes, the oil through hole of both sides has constituteed the oil circuit that can lead to with hollow roller's central through hole on the holder, the holder is installed between inner circle and outer lane, the circlip fixed setting on inner circle tapered roller way. Compared with the traditional tapered roller bearing, the utility model adopts a machined solid retainer, and the retainer is guided by the inner ring flange and the roller path; the rotation precision and the limit rotation speed of the bearing are improved.
Description
Technical Field
The utility model relates to a bearing unit technical field, in particular to tapered roller bearing suitable for high-speed rotation.
Background
The common tapered roller bearing generally adopts a stamped steel plate retainer or a strut retainer. In any cage, roller guide is used. However, at high speeds, the rotation of the rolling elements becomes unstable when the rotational speed of the rolling elements increases, so that the cage guided by the rolling elements is only suitable for use at medium and low speeds.
SUMMERY OF THE UTILITY MODEL
The utility model aims at the above-mentioned problem that exists among the prior art, provide one kind and adopted machine tooling entity holder, the holder is by inner circle external diameter and raceway guide, has improved a tapered roller bearing who is applicable to high-speed rotation of the rotatory precision of holder.
The utility model adopts the technical proposal that:
the utility model provides a tapered roller bearing suitable for high-speed rotation, includes inner circle, outer lane, a plurality of hollow roller, holder and circlip, characterized by the outer terminal surface of inner circle on and the outer lane inner wall on be corresponding tapered roller way respectively, the inner circle is equipped with single flange, the holder be with tapered roller way assorted conical body, be provided with a plurality of roller pocket holes respectively on the holder, be provided with the oil through hole respectively on the both ends face in a plurality of roller pocket holes, a plurality of hollow roller install respectively in a plurality of roller pocket holes, the oil through hole of both sides has constituteed the oil circuit that can lead to with hollow roller's central through hole on the holder, the holder is installed between inner circle and outer lane, circlip fixed the setting on the inner circle raceway. The two sides of the retainer are respectively guided by the flanges of the inner ring and the roller path of the inner ring.
Compared with the traditional tapered roller bearing, the utility model adopts a machined solid retainer, and the retainer is guided by the outer diameter of the inner ring and the roller path; the rotation precision and the limit rotation speed of the bearing are improved.

Detailed Description
A tapered roller bearing suitable for high-speed rotation comprises an inner ring 1, an outer ring 2, a plurality of hollow rollers 3, a retainer 4 and a spring retainer ring 5, wherein the inner ring 1 is not provided with a flange 8, the inner ring 1, the plurality of hollow rollers 3, the retainer 4 and the spring retainer ring 5 form an inner assembly, and the tapered roller bearing and the outer ring 2 form the tapered roller bearing together. A retainer 4 of the bearing is provided with a circle of uniformly distributed roller pockets 6 which are respectively used for loading the hollow rollers 3, oil through holes 7 are respectively arranged at two sides of each roller pocket 6, and the oil through holes 7 at two sides of the retainer 4 and a central through hole of each hollow roller 3 form an oil path which can be used for oil through, so that the heat dissipation and the lubrication of the bearing are facilitated. The two sides of the retainer 4 are respectively guided by the flanges of the inner ring 1 and the roller paths of the inner ring 1, so that the retainer 4 is more stable in the high-speed running process of the bearing, and the maximum limit rotating speed of the bearing is increased.
