Problems solved by technology

[0002] The structure of the gear is various and various. As a common power transmission method, it is widely used in various fields, and the spiral bevel gear has high transmission efficiency, stable transmission ratio, large arc overlap coefficient, and high load-carrying capacity. High, smooth transmission, reliable work, compact structure, long life, low noise, etc., are often used in the movement and power transmission between two intersecting shafts, as an important component in a mechanical transmission, affecting The service life and transmission efficiency of the whole machine are also extremely demanding on its strength and precision. The early high-performance spiral bevel gear products are almost all imported from abroad, the procurement cost is extremely high, and they lack market competitiveness. However, due to recent years With the continuous development and innovation of the domestic powder metallurgy industry, many new processes have appeared relatively, so many of these high-performance products are now more and more tending to be localized, which has brought huge business opportunities, and there are more and more More and more powder metallurgy industries are willing to invest in the development of such high-performance products
