The load torque of DC gearbox (also known as DC gear motor) has a direct relationship with the speed and current. The speed of the motor is linear with the increase of load, and the current increases linearly. Selection of specifications, should try to work in the vicinity of its maximum efficiency point, in order to obtain the ideal operating performance, working life and performance stability.

Generally, the DC gear motor and micro DC motor has the same use environment, for special needs, such as environmental temperature, overload condition, current limit, must be explained in advance.

The working life of the gear box is generally more than the working life of the DC motor, which can usually reach 1000 to 3000 hours. The minimum service life of our   reduction gear motor can be more than 1800 hours, the longest can go to 5000 hours.

The gear box's total reduction ratio is generally in the range of 1:4 to 1:1000. After special design, it can achieve a greater reduction ratio, but a lot of gear box is not allowed to "turn", that is not the output shaft of the gear box as the driving shaft, forced back.

Due to the strength of the gear, the gear motor may not be able to withstand the torque, when the total transmission is high, the load can't exceed the maximum allowable load torque. Gear box is made up of multiple gears. Each stage comprises a pair of mutually engaged gears, consisting of a piece of sheet shaped gear and a small gear. The first pinion is mounted on the output shaft of the motor. The bearing of the output shaft of the gearbox is usually made of copper or iron material for bearing with oil.
