Motor gear box
The load torque of a DC gear motor has a direct relationship with the speed and current. The speed decreases linearly with the increase of the load, and the current increases linearly. When selecting specifications, try to maximize the efficiency
Work near the point to obtain ideal running performance, working life and characteristic stability.
Generally, the use environment of DC gear motors is the same as that of micro DC motors. If there are special needs, such as ambient temperature, overload conditions, current limits, etc., they must be explained in advance.
The working life of the gearbox generally exceeds the working life of the DC motor, usually up to 1000 to 3000 hours.
The total reduction ratio of the gearbox is generally in the range of 1:10 to 1:500. After a special design, it can reach 1:1000 or greater, but the gearbox with a large reduction ratio is not allowed to "reverse", that is, it cannot be
The output shaft of the wheel box is used as the driving shaft, forcibly reversed.
Due to the limitation of gear strength, when the total transmission is large, the gear motor may not be able to withstand the locked-rotor torque. At this time, the load torque cannot exceed the maximum allowable short-term load torque. The gearbox consists of multiple stages
Gear pair composition. Each stage includes a pair of meshing gear pairs consisting of a sheet gear and a pinion gear. The pinion gear is mounted on the output shaft of the motor. The bearing used for the output shaft of the gearbox, usually
It is an oil-impregnated bearing made of copper or iron sintered.
