Pivoting support bearing integral holder and process thereof

Abstract

The invention discloses an integral cage of a slewing bearing. Diameter of the integral cage is over 1000mm, width thereof is over 40mm, and thickness thereof is 4-8mm. The invention further discloses a production process of the integral bearing cage. The production process comprises the following steps: a) cutting off raw steel; b) abrasive machining on surface; c) punching round holes; d) abrasive machining on the punched round holes; e) roughly rounding, wherein, a non-equiangular rounding structure is employed for rounding, the non-equiangular rounding structure comprises a driving rollerand two driven rollers, and the distance between contact points of the two driven rollers and the integral bearing cage is less than or equal to twice of the center distance between two adjacent circular holes; f) welding; and g) finely rounding. The production process can be adopted to produce large integral bearing cages, and the obtained large integral bearing cages have relatively simple integral molding and assembly process.

Description

An integral cage of a slewing ring bearing and its production process technical field The invention relates to an integral cage of a slewing support bearing and a production process thereof, belonging to the field of bearings. Background technique The development and utilization of new energy has increasingly become a focus of production and research. In nature, the wind is a renewable, non-polluting and huge reserves of energy. With the global warming and energy crisis, all countries are stepping up the development and utilization of wind power to minimize the emission of carbon dioxide and other greenhouse gases and protect the earth we depend on for survival. The slewing ring bearing cage used in wind power generation equipment has large volume, high precision, special structure, harsh service conditions and application environment, and basically loses the possibility of disassembly and repair once it is installed in the equipment. At present, there are a few manufac...

Problems solved by technology

At present, there are a few manufacturers in China who use split and multi-piece assembly to manufacture and assemble large bearing cages, which reduces the assembly performance requirements of the bearings, and the manufacturing cost is high and the assembly process is cumbersome.
