Abstract

The utility model relates to the field of bearings, and particularly relates to a cylindrical roller bearing which comprises an inner ring, an outer ring, a cylindrical roller and a thrust end cover, wherein the thrust end cover comprises a first thrust end cover and a second thrust end cover, the cylindrical roller is arranged between the inner ring and the outer ring, a thrust ring is arranged at the right end of the inner ring, grooves are formed in the outer side of the middle of the inner ring and the inner side of the middle of the outer ring, the first thrust end cover is arranged at left ends of the inner ring and the outer ring, the second thrust end cover is arranged at the right ends of the inner ring and the outer ring, and the first thrust end cover and the second thrust end cover are fixed at two ends of the inner ring through bolts. According to the cylindrical roller bearing, the grooves are formed in the outer side of the middle of the inner ring and the inner ring of the middle of the outer ring, even if dust and other impurities are carried in a bearing assembling process, the dust and the impurities can not be discharged in the grooves in the bearing operating process without causing the influence to the operation of the bearing; because a holder is eliminated, the cylindrical roller bearing is simpler in structure and more convenient to assemble.

Description

A kind of roller bearing
Technical field
The utility model relates to a kind of field of bearings, is specifically related to a kind of roller bearing.
Background technique
Bearing is one of requisite Component of rotary machine, bearing is generally arranged on rotatingshaft, its inner ring is followed rotatingshaft and is rotated, outer ring maintains static, and bearing, in installation process, tends to bring into dust and other foreign material, dust and foreign material can make roller frictional force increase, reduce rotating speed, affect working efficiency, also may cause the working life of reduction equipment.
Model utility content
The purpose of this utility model is, for the defect of prior art and deficiency, to provide roller bearing a kind of simple in structure, easy to assembly.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of roller bearing described in the utility model, described roller bearing comprises inner ring, outer ring, cylindrical roller and thrust end cap, described thrust end cap comprises the first thrust end cap and the second thrust end cap, described cylindrical roller is arranged between inner ring and outer ring, described inner ring right-hand member is provided with thrust ring, outside, described inner ring middle part and inner side, middle part, outer ring are provided with groove, described the first thrust end cap is arranged on inner ring and outer ring left end, described the second thrust end cap is arranged on inner ring and outer ring right-hand member, described the first thrust end cap and the second thrust end cap are fixed by screws in inner ring two ends.
Further technological scheme, described the first thrust end cap and the second thrust end cap internal diameter equate with the internal diameter of inner ring, external diameter equates with the external diameter of outer ring.
Further technological scheme, described screw is sunk screw.
The beneficial effects of the utility model are: the utility model is provided with groove in outside, inner ring middle part and inner side, middle part, outer ring, even if bring dust and other foreign material in bearing assemble process, in bearing operation process, dust and foreign material can be discharged in groove, can not impact bearing operation, and the utility model has been cancelled retainer, make structure simpler, assemble convenient.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of roller bearing of the present utility model;
Description of reference numerals:
1, inner ring; 2, screw; 3, the first thrust end cap; 4, outer ring;
