Asymmetrical multi-subdivision bearing and manufacture process thereof

Abstract

The invention relates to the field of large-size pivoting support products, in particular to an asymmetrical multi-subdivision bearing and a manufacture process thereof. The asymmetrical multi-subdivision bearing is characterized in that an inner ring and an outer ring are of asymmetrical subdivision structures formed by connecting a plurality of sections of arc plates; the inner ring and the outer ring spliced by the arc plates respectively form closed round roller paths, and a retaining frame is arranged between the roller paths; rollers are uniformly and non-uniformly arranged on the retaining frame; and a rolling body drives the retaining frame to do rotary motions. The processing process of the inner ring, the outer ring and flanges comprises the following steps of: (1) forging and annealing; (2) carrying out machining, roll curving and stabilizing treatment; (3) tempering and shaping; (4) preliminarily working; (5) carrying out induction hardening on a working surface; and (6) finishing. Compared with the prior art, the invention effectively solves the problems of relevant links of processing, transport, assembly, maintenance, and the like of large-size bearings.

Description

technical field [0001] The invention relates to the field of large slewing bearing products, in particular to an asymmetric multi-section bearing with novel structure and technology and its manufacturing technology. Background technique [0002] Large-scale slewing bearing products are widely used in wind power generation, port ships, mining machinery, military industry and other fields. With the improvement of technology and changes in market demand, the demand for large-size slewing bearing products is increasing. In the existing technology, Most of the large-size slewing bearings are integral structures. When the slewing diameter exceeds 5 meters, there are many inconveniences in the processing and transportation of the blanks and finished products. Contents of the invention [0003] The object of the present invention is to provide an asymmetric multi-section bearing, which is designed in a multi-section form for large-size bearings, which is convenient for transportat...
