Description

Slewing bearing with separated gear ring and bearing

Technical Field

The utility model relates to the technical field of slewing bearings, in particular to a slewing bearing with a gear ring and a bearing separated from each other.

Background

Slewing bearing products are widely used in modern industry, and are called "joints of machines", which are important transmission parts necessary for machines which need to perform relative rotation movement between two objects and bear axial force, radial force and tilting moment.

The traditional slewing bearing is generally used for directly processing a gear ring on an outer ring, but when the traditional slewing bearing is applied to an environment with fast gear ring abrasion and corrosion failure, the problems of high product replacement cost and high replacement difficulty can be caused.

The inventor therefore devised a swivel support with a ring gear and a separate bearing.
