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.

Needle roller, also known as needle cylinder. A metal cylinder with steel needles planted on the surface. It is installed in the drafting zone for controlling and carding fibers. It is used on spun silk and wool spinning roving frame, carded wool spinning frame, spun spinning and shaft spinning frame. The main body of the needle roller is a copper cylinder with small holes drilled on the surface and steel needles are planted in the holes. Both ends of the cylinder are equipped with a flange, the surface of which is slightly higher than the needle tip to protect the needle tip from damage. The main parameters of the needle roller are: bottom diameter, outer diameter, needle width, needle height, needle density, needle angle and needle number. In order to adapt to the processing of different types of fibers, the small carding roller on the rotor spinning machine has the saw teeth replaced with needles, also called needle rollers.
