Secondary infiltration technology for gear forming

Abstract

The invention discloses a secondary infiltration technology for gear forming, and relates to the technical field of the gear machining technology. According to the work principle of the secondary infiltration technology, metallurgy powder is placed in a grinding machine to be subjected to grinding treatment, screening is conducted after grinding, and screened metallurgy powder is obtained; and thescreened metallurgy powder is placed in a gear forming machine to be pressed and formed, a gear blank with the pressing density being 6.6-6.8 is obtained, the gear blank is placed in a sintering furnace to be sintered, the sintering temperature is 1,120 DEG C, and protective gas is continuously inflated in the process. After the above technical scheme is adopted, the secondary infiltration technology has the beneficial effects that a traditional technology is optimized, the forming technology is simplified, the usage value is high, the technology cost is low, the mechanical performance of a formed gear is excellent, compactness of the gear is improved, strength and abrasion resistance can be improved by 15%-30%, and the requirements of customers for products can be met; and compared withconventionally treated and manufactured gears, the mechanical performance is improved by 50%, the performance in the same industry field is excellent, and generalization performance is high.

Description

technical field [0001] The invention relates to the technical field of gear processing technology, in particular to a secondary infiltration process for gear forming. Background technique [0002] A gear is a mechanical element with gears on the rim that continuously mesh to transmit motion and power. [0003] In 2010, the total industrial output value of the entire gear industry was 94.635 billion yuan, and the market demand for the entire gear industry exceeded 140 billion yuan, ranking second in the world. Judging from various factors such as scale and sales, the gear industry has become a "leading" industry in the field of basic parts for general machinery parts in China. [0004] As competition in the gear industry continues to intensify, mergers and acquisitions among large-scale gear companies and capital operations are becoming increasingly frequent, and domestic excellent gear manufacturers are paying more and more attention to the research of the industry market, ...

AI Technical Summary

Problems solved by technology

[0006] At present, the gear forming process in the market is often based on the traditional process. The traditional process is complex, the gear forming process is cumbersome, the use value is not high, the process cost is extremely high, the mechanical properties of the formed gear are low, and it is difficult to improve the compactness, strength and wear resistance of the gear. All are poor, unable to meet customer requirements for products, low performance in the field of peers and poor promotion
