Vibrating screen self-aligning roller bearing

Abstract

The invention discloses a vibrating screen self-aligning roller bearing and belongs to the field of mechanical equipment. The vibrating screen self-aligning roller bearing comprises an outer ring andan inner ring positioned inside the outer ring. A double-row rolling device is arranged between the outer ring and the inner ring, double-row roller ways are arranged on the inner ring, and a bulge, between the double-row roller ways, on the inner ring is a high guide pitch diameter. The double-row rolling device comprises a double-row rolling body and a double-row retainer used for supporting thedouble-row rolling body, and the double-row rolling body is placed on the double-row roller ways and moves on the double-row roller ways. The double-row roller ways and the roller double-guide retainer are adopted, the double-row roller ways are adopted for guiding, locking sintering damage to the bearing due to the fact that the retainer and the rolling body are clamped under the impact load isgreatly reduced, due to the fact that the double-row retainer is adopted, mutual interference of the retainer is avoided in the rotating process, and the rolling body and the retainer cannot be clamped due to part of dust. The service life of the bearing is prolonged, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment and relates to a self-aligning roller bearing of a vibrating screen. Background technique [0002] Roller bearings are a type of rolling bearings and are one of the most widely used components in modern machinery. It relies on the rolling contact between the main elements to support the rotating parts. Roller bearings are now mostly standardized. Roller bearings have the advantages of small starting torque, high rotation accuracy, and convenient selection. [0003] Roller bearings rely on the rolling contact between the main parts to support the rotating parts. Different roller bearings can withstand different radial and axial forces. However, the roller bearings on the market now have defects such as the jamming of the cage and the rolling elements under the impact load, which causes the bearing to be locked and sintered, the bearing speed of the vibrating screen is low, the load...

AI Technical Summary

Problems solved by technology

However, the roller bearings on the market now have defects such as the jamming of the cage and the rolling elements under the impact load, which causes the bearing to be locked and sintered, the bearing speed of the vibrating screen is low, the load is low, the impact resistance is poor, and the service life of the bearing is short.
