Gear motor can be divided into gear reducer, gear box, which is commonly used to reduce the output speed; (ratio), provide torque (torque) load capacity, achieve the ideal transmission effect, it slow down and reduce the load inertia and the reduction ratio is reduced because of inertia; different power reducer motor used in different scenarios and areas; according to the structure is divided into gear motor gear motor, planetary gear motor, dc gear motor, worm gear motor, at the same time for different scenarios; for example million to motor manufacture the gear motor is widely used in the field of industrial automation, intelligent automobile transmission, robot transmission, Home Furnishing. The motor speed reducer, gear box is often said; change the transmission direction, for example we use two sector gears can be transferred to another force on a vertical axis of rotation; rotation torque change. Under the condition of the same power, the faster the speed of gear shaft torque by smaller, and vice versa the more; clutch function: we can separate the two original meshed gears, the engine and the load separately. For example the brake clutch; the distribution of power. For example, we can use an engine through a gear box main shaft drives a number from the axis, so as to achieve an engine to drive a plurality of load function. The working principle of gear box: gear box is used to change speed, and the gear box or the reduction motor is mostly changed by gear. The principle is that a big gear, a gear or a pinion with a big gear.
