Abstract

The invention belongs to the technical field of machinery, and relates to an eccentric roller assembly supporting rotation structure and an adjusting method thereof. The structure comprises a mounting frame (12) and a plurality of eccentric roller assemblies (15), wherein the plurality of eccentric roller assemblies (15) are fixed on the mounting frame (12) through eccentric shafts and are uniformly arranged on a certain circumference of the mounting frame (12). According to the eccentric roller assembly supporting rotation structure, rotation supporting is completed through the multiple eccentric roller assemblies, so that the diameter of a rotating body capable of being supported by the eccentric wheel assemblies and the mounting frame is far greater than that of a rotating body capable of being supported by an integrated bearing, and limitation on the diameter size of a rotating part during design is relieved.

Description

technical field

[0001] The invention belongs to the technical field of machinery, and relates to an eccentric roller assembly supporting rotary structure and an adjusting method thereof. Background technique

[0002] In terms of supporting the rotation of rotating parts, bearings have been widely used in large-scale rotating devices such as lifting, excavation, construction, ports, ships, and high-precision radar and missile launches. At the same time, we can also design, develop and produce various special structure slewing ring bearings according to the specific requirements of users.

[0003] At present, the largest integral bearing diameter that can be manufactured is 9.5m, and the split bearing is 12.4m. This kind of large bearing is extremely difficult to process, the accuracy is difficult to guarantee, and the price is expensive. Moreover, with the advancement of industry, various industries have put forward greater requirements for the diameter of the rotating parts...
