Description

Deep groove ball bearing device

Technical Field

The utility model relates to the technical field of bearing equipment, in particular to a deep groove ball bearing device.

Background

Deep groove ball bearings are one of the most widely used rolling bearings. The basic deep groove ball bearing is composed of an outer ring, an inner ring, a group of steel balls and a group of retainer. The deep groove ball bearing has a single-row structure and a double-row structure, the deep groove ball structure is divided into a sealing structure and an open structure, the open structure means that the bearing does not have a sealing structure, and the sealing type deep groove ball is divided into a dustproof sealing structure and an oil-proof sealing structure. The dustproof sealing cover material is punched by a steel plate, and only the function of simply preventing dust from entering the bearing raceway is achieved. The oil-proof type is a contact type oil seal, and can effectively prevent lubricating grease in the bearing from overflowing.

At present, in order to avoid the influence of radial and axial forces of an inner ring and an outer ring on a steel ball when the deep groove ball bearing rotates at a high speed in use, a steel ball retainer is generally adopted to limit and maintain the steel ball, so that the steel ball is not only rubbed with the inner ring and the outer ring but also rubbed with the retainer when the deep groove ball bearing is used, the steel ball is quickly abraded, lubricating grease is continuously accumulated on the retainer after the bearing with the retainer is filled with the lubricating grease, and the contact between the steel ball and the inner ring and the outer ring is less, so that the deep groove ball bearing device is provided.
