Description

Retainer capable of being stably supported and used for self-aligning roller bearing

Technical Field

The utility model relates to a bearing retainer, in particular to a retainer for a self-aligning roller bearing, which can be stably supported.

Background

The self-aligning roller bearing is a bearing assembled with drum-shaped rollers between an inner ring with two raceways and an outer ring with spherical raceways. The self-aligning roller bearing is provided with two rows of rollers, and mainly bears radial load and can bear axial load in any direction. The bearing has high radial load capacity, is particularly suitable for working under heavy load or vibration load, but cannot bear pure axial load. The outer ring raceway of the bearing is spherical, so that the bearing has good aligning performance and can compensate the coaxiality error. The self-aligning roller bearing is generally used for paper making machinery, speed reducing devices, axles of railway vehicles, bearing seats of gear boxes of rolling mills, rollers of rolling mills, crushers, vibrating screens, printing machinery, woodworking machinery, speed reducers for various industries, vertical self-aligning bearings with seats and the like. The retainer of the conventional self-aligning roller bearing is generally limited outside a drum-shaped roller, and the outer wall of the drum-shaped roller is easy to rub the retainer when the drum-shaped roller rotates, so that the outer wall of the drum-shaped roller is abraded, and the rotation precision of the self-aligning roller bearing is further influenced; the drum roller is seriously worn, and the service life of the self-aligning roller bearing is also influenced.

Disclosure of Invention

In order to overcome the defects in the background art, the utility model discloses a cage for a self-aligning roller bearing capable of being stably supported, which supports drum-shaped rollers on two sides of a ring body by using inserting columns A and inserting columns B which are respectively arranged on two bottom surfaces of the ring body at intervals, and achieves the purposes of reducing abrasion of the outer edge surface of the drum-shaped roller and prolonging the service life by using the support in the drum-shaped roller to rotate the drum-shaped roller.

In order to realize the purpose, the utility model adopts the following technical scheme:

a retainer for a self-aligning roller bearing capable of being stably supported comprises a ring body, a triangular convex ring is arranged on the inner ring surface of the ring body, a plurality of supporting columns A are arranged on one bottom surface of the ring body at intervals, a plug column A with the outer end inclined to the axis of the ring body is arranged at the end portion of each supporting column A, a blocking head A coaxial with the plug column A is arranged between each supporting column A and the plug column A, a screw hole is formed in the end portion of the plug column A, a screw is connected to the screw hole in a threaded mode, a plurality of supporting columns B are arranged on the other bottom surface of the ring body at intervals, the number of the supporting columns B is the same as that of the supporting columns A, the supporting columns B and the supporting columns A are arranged in a staggered mode, a plug column B with the outer end inclined to the axis of the ring body is arranged at the end portion of each supporting column B, a blocking head B coaxial with the plug column B is arranged between the supporting columns B and the end portion of the plug column B is also provided with a screw hole, and a screw is also connected to the screw hole in a threaded mode.

The cage for the self-aligning roller bearing capable of being stably supported is characterized in that the ring body, the pillar A, the inserting pillar A, the pillar B and the inserting pillar B are made of copper respectively.

The diameter of the stop head A and the diameter of the stop head B of the retainer for the self-aligning roller bearing which can be stably supported are respectively the same as the diameter of a nut arranged on the screw.

Due to the adoption of the technical scheme, the utility model has the following beneficial effects:

according to the cage for the stably supported self-aligning roller bearing, the plug posts A and the plug posts B which are respectively arranged on the two bottom surfaces of the ring body at intervals are used for supporting the drum-shaped rollers on the two sides of the ring body, so that the purposes of reducing abrasion of the outer edge surfaces of the drum-shaped rollers and prolonging the service life of the drum-shaped rollers by utilizing the support in the drum-shaped rollers are achieved; the drum-shaped roller has the advantages of ingenious design and strong practicability, effectively prolongs the service life of the drum-shaped roller, and has great market popularization value.
