An anti-deformation and dust-proof deep groove ball bearing

Abstract

The invention relates to bearing technology, and discloses a deformation-resistant and dust-proof deep groove ball bearing, which includes an outer ring, an inner ring, a cage and a rolling element, and a dust-proof device for blocking the gap between the inner ring and the outer ring is fixed on both sides of the inner ring. Cover, the dust cover is provided with a support structure, the support structure includes the inner ring wall extending on the inner wall of the dust cover and the installation ring that fits the outer ring wall of the inner ring, and the slots arranged at intervals on the outer ring wall of the installation ring And the support body inserted and fixed on the slot, the support body includes a support rod whose lower end is partially inserted into the slot, an elastic gasket located at the bottom of the support rod and a support ball located at the upper end of the support rod, and a support ball on the inner wall of the outer ring There is an auxiliary raceway for the support ball to roll on the opposite side, and a self-lubricating mechanism for self-lubricating when the support ball and the auxiliary rolling slide fit on the cage. This bearing has dual functions of dust prevention and significantly increased radial load , can effectively prolong the service life of the bearing.

Description

Technical field [0001] The present invention relates to the field of bearing technology, specifically a deformation-resistant dust-proof deep groove ball bearing. Background [0002] Deep groove ball bearings, also known as single row centripetal ball bearings, are the most widely used rolling bearings, which are characterized by small frictional resistance, high speed, can be used to bear the joint load of radial and axial forces at the same time, but also used to bear the axial load on the parts. [0003] Existing deep groove ball bearings generally include an outer ring, an inner ring, a rolling element and a cage, and the rolling elements are located on the cage and are mated to the rolling friction of both the outer and inner rings. Due to its structural characteristics, deep groove ball bearings can withstand a certain radial load, but once the radial load is too large, it will aggravate the degree of wear between the rolling element and the outer ring and the inner ring, r...

AI Technical Summary

Problems solved by technology

Due to its structural characteristics, deep groove ball bearings can withstand a certain radial load. However, once the radial load is too large, it will intensify the degree of wear between the rolling elements and the outer ring and inner ring, resulting in deformation of the rolling elements and eventually lead to The structure in which the rolling elements are stuck and the bearing is scrapped will cause damage to the equipment
