There are two main uses of gears: one is the transmission movement and the other is the transmission of power. At present, domestic plastic gears are mainly used to transmit motion, and the United States is now increasingly adopting plastic gears in the choice of transmission power. This is because plastic gears have many advantages, such as low transmission noise, vibration absorption, self-lubrication, and so on. Moreover, plastic gears can be opened and processed with high production efficiency.
There will be more and more applications of plastic gears in the gear industry. This is a worldwide trend. According to Luo Baihui, Secretary-General of the International Model Association, the application of domestic gear molds can be roughly divided into three areas: plastic gear molds, powder metallurgy gear molds and precision forging bevel gear molds. Among them, the demand for plastic gear molds is relatively large.
At present, the middle and low gear molds can be produced in China, and high-grade gear molds rely on imports. There are not many factories in China that specialize in gear molds. Most of them use gear factories to make their own gear molds. Gear factories often set up a construction section or a workshop to take on this task. For precision forging bevel gears, bevel gear molds manufactured by companies such as Zhuzhou Gear, Jiangsu Spacecraft, and Pacific Precision Forging are relatively good in the gear mold industry, and the quality of their precision forging bevel gears is also high. In terms of plastic gears, in general, plastic gears and their molds are mainly distributed in two regions. One is Ningbo, Zhejiang, where there are more than 340 plastic gear factories and is also China's largest plastic gear mold production base; the other is Shenzhen Baoan. , Hong Kong-owned enterprises, high product accuracy, mainly for export.
Looking at the status quo of our country's gear molds can be described as mixed. Hi there is a certain basis for the production of gear molds, and the general trend in the development of plastic gears will bring greater market space for gear molds; the worry is that the level of domestic production gear molds is still at a distance from the world’s advanced level, and In the gear industry, especially the development trend of the plastic gear industry, the response to market changes in the domestic market is not keen, and it is difficult for supporting research to keep up with market demand.
