The gear spindle adopts a gear variable speed structure, suitable for high torque machining of steel parts and high-speed cutting of non-ferrous metals, achieving the effect of small machine tools with high torque. It has a wider range of use and higher efficiency than machine tools of the same specifications on the market. Choosing a gear spindle box with a 1:4 or 1:8 reduction ratio and adding a frequency converter can achieve stepless speed change and automatic speed regulation, achieving low speed and high torque. It is suitable for low-speed threading and drilling larger holes at low speed. Gear spindles are generally used for low speed and high torque transmission equipment. They achieve deceleration by transmitting electric motors or other high-speed transmission equipment through reducers to the output shaft gears.

Due to the strength limitation of the gear spindle, when the total transmission is large, the gear motor may not be able to withstand the locked torque, and the load torque at this time cannot exceed the maximum allowable short-term load torque. The gearbox is composed of multi-level gear pairs. Each stage consists of a pair of meshing gear pairs composed of plate gears and small gears. A small gear is installed on the output shaft of the electric motor. The bearings used for the output shaft of a gearbox are usually oil containing bearings made by sintering copper or iron materials. The usage environment of the gear spindle is the same as that of a micro DC motor. If there are special needs, such as ambient temperature, overload conditions, current limits, etc., they must be explained in advance.
