In mechanical manufacturing, there are many gear processing methods. According to the principle of tooth profile travel, it can be divided into forming methods, such as milling teeth on the milling machine with a milling cutter; generating methods, such as hobbing gears on gear hobbing with a hob.

　　The gear motor is a relatively precise machine, the purpose of using it is to reduce speed and increase torque. The gear reducer has many different types, which have different applications.　　According to the transmission type, it can be divided into gear reducer, worm reducer, and planetary reduce

　　Spur Gear　　A classical gear type, the dentate part is parallel to the central axis. The dentate concave part is not upright(slightly curved). This design can reduce the speed and torque between the gears when meshing each other, increase utilization power.　　Helical Gear　　In realistic applications,

for robot motor, how we choose. today, let us see.
