Gearboxes are generally used for low-speed and high torque transmission equipment. They reduce the speed of electric motors, internal combustion engines, or other high-speed power by meshing the gears with fewer teeth on the input shaft of the gearbox with the large gears on the output shaft. Ordinary gearboxes also have several pairs of gears with the same principle to achieve the desired reduction effect. The ratio of the number of teeth between the large and small gears is the transmission ratio.

That's not quite accurate.

A reducer is a power transmission mechanism that uses a gear speed converter to reduce the number of revolutions of an electric motor (motor) to the desired number of revolutions and obtain a larger torque. Among the mechanisms currently used for transmitting power and motion, the application range of reducers is quite extensive. It can be found in almost all types of mechanical transmission systems, from ships, cars, locomotives in transportation, heavy machinery used in construction, processing tools and automated production equipment used in the machinery industry, to common household appliances, clocks and so on in daily life. The application of reducers can be seen from the transmission of large power to small loads and precise angle transmission. In industrial applications, reducers have the functions of reducing speed and increasing torque. Therefore, it is widely used in speed and torque conversion equipment.

effect

The main function of a reducer is to reduce speed while increasing output torque. The torque output ratio is calculated by multiplying the motor output by the reduction ratio, but it should be noted that it should not exceed the rated torque of the reducer.

Deceleration also reduces the inertia of the load, which is the square of the reduction ratio. You can see that most motors have an inertia value.
