Shaped turntable bearing for sewage treatment

Abstract

The invention provides a shaped turntable bearing for sewage treatment. The bearing comprises an outer ring, an inner ring and steel balls arranged between the outer ring and the inner ring, wherein a built-in space communicated with the outside is formed in the outer ring, the built-in space is provided with a baffle; the roller space of the steel balls is formed by the baffle and the side wall of the built-in space; wear resistant steel rings are correspondingly embedded in the upper part and the lower part of the roller space; the steel balls roll on the wear resistant steel rings; an extension part is formed in the inner ring, extends into the built-in space of the outer ring and seals the roller space. The shaped turntable bearing is assembled after casting and forming of cast steel materials, so that the utilization rate of materials is increased, the processing is facilitated and the cost is also reduced; meanwhile, by arranging a rolling roller path formed by wear resistant steel rings for the steel balls, the wear resistance of the rolling roller path is increased and the service life of the bearing is prolonged.

Description

technical field [0001] The invention relates to a turntable bearing in the mechanical field, in particular to a special-shaped turntable bearing for sewage treatment. Background technique [0002] The slewing bearings used for sewage treatment in the prior art generally use special-shaped slewing bearings in consideration of the particularity of sewage treatment. These special-shaped slewing bearings are small in force, but the structure is extremely complicated. Generally, the forging method is used to manufacture each part and then Assembly, but there are problems such as low material utilization, high cost, and difficult processing. Moreover, after forging, the strength of the raceway is very low, resulting in a very low service life of the special-shaped slewing bearing, which cannot meet the needs well. Contents of the invention [0003] In order to solve the problems of difficult processing and low service life of special-shaped slewing bearings for sewage treatment...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the problems of difficult processing and low service life of special-shaped slewing bearings for sewage treatment in the prior art, the invention provides a special-shaped slewing bearing for sewage treatment. The components of the slewing bearing are assembled by casting with cast steel materials , which improves the utilization rate of materials, not only facilitates processing, but also reduces costs; at the same time, the service life of bearings is improved by setting wear-resistant steel rings
