[0002] Gear transmission is a common and widely used mechanical transmission method in a reduction mechanism, and has the following uses: 1. Speed ​​and torque transmission: Gear transmission is mainly used to transmit rotational motion and torque. They can convert the input power into the required output speed and torque, which is used to drive various mechanical equipment and systems. 2. Motion control: Due to the high transmission accuracy and reliability of gear transmission, they are often used in applications that require precise motion control, such as industrial machinery, machine tools, automation equipment, etc. 3. Speed ​​conversion: Gear transmission mechanisms can achieve speed conversion through the combination and size selection of different gears. This makes them very useful in applications that need to adjust or match different working speeds. 4. Power transmission: Gear transmission mechanisms are able to transmit high power and are suitable for applications that need to transmit high torque and high power, such as automotive transmission systems, wind turbines, construction machinery, etc.

[0003] Gear transmission mechanisms have a wide range of uses in many fields. They are a reliable and efficient transmission method and are widely used in various mechanical equipment and systems. The transmission efficiency of gear transmission mechanisms is usually above 85%; gear transmission mechanisms have high transmission accuracy and can achieve precise speed and position control; gear transmission mechanisms have high load-bearing capacity due to the design and material selection of gears. They can withstand large torques and loads and are suitable for applications that require high power transmission; gear transmission mechanisms usually have a long service life and stable and reliable performance. They can work under long-term and heavy load conditions and are not prone to failure.

[0004] The processing technology of gears is relatively complicated, requiring the use of many precision machine tools and high-precision testing instruments. At the same time, the manufacturing of gears also requires a high level of technology. High precision requirements: The precision requirements of gears are high, and the accuracy of the tooth surface and the straightness of the axle must be guaranteed, otherwise it will affect the efficiency and service life of the gear transmission. Gear grinding is difficult: Gear grinding is difficult because the geometric dimensions and shapes of gears are very complex, and the precision requirements of gears are high. This makes the gear cost high and the production efficiency low. Summary of the invention
