How to Distinguish Between Gearbox and Geared Motor

The full name of the reducer is a reduction motor, which is a combination of a motor and a gearbox—a motor reducer integrated machine. , transmission, deceleration, lifting torque (carrying capacity) and other functions; transmission motors are divided into DC brush motors, DC brushless motors, stepper motors, coreless motors, permanent magnet motors, electric motors, etc. according to the structure type as reducer transmission The source provides high-speed and low-torque speed output. Under the action of the gearbox, the output speed is reduced and the torque is increased to achieve the ideal transmission effect.

The gearbox is also called a reducer, and its main structure is assembled from a plurality of large and small transmission meshing gear sets, which are used in the reducer. According to the purpose and gear structure, the gearbox is divided into planetary gearbox, cylindrical gearbox, spur gearbox, parallel gearbox, helical gearbox, bevel gearbox, worm gearbox, etc., and according to the material, it is divided into plastic gearbox and metal gear Gearboxes, such as planetary gearboxes, are adopted due to the characteristics of precision, long life, small size, transmission efficiency, and wide range of deceleration. The structure of planetary gearboxes is composed of planetary gears, sun gears, ring gears, transmission shafts, washers, and box assemblies. become.

What is the difference between a gearbox and a reducer?

In general, there is no difference between a reducer and a gearbox, but they are called differently, and they all refer to the same thing. In fact, they cannot be completely equated. A reducer is a reducer with a motor installed, called a geared motor, or a three-in-one reducer (including a motor, a reducer, and a brake). Default means the same thing. Reducer and reducer can be divided into: gear reducer, worm reducer and planetary reducer, etc., or gear reducer, worm reducer and planetary
gear reducer, etc. The gearbox is divided into a reduction gearbox, a speed increase gearbox, and a speed change gearbox. The reducer is the reduction gearbox among them. However, the reducer should also include non-gear transmission (or completely non-gear transmission reducer, as long as it can achieve the deceleration effect, it does not need to use gear transmission, sprockets, pulleys, etc., can be used for deceleration transmission, in this case Under the circumstances, the reducer cannot be completely equivalent to the gearbox. And because the transmission efficiency of the gearbox is higher than other transmission methods, and the transmission ratio is accurate, so in most cases, the reducer is manufactured by gear transmission, so it is customary to Think of the reducer and the gearbox as one thing.

The reducer is a reducer with a motor installed, and the gearbox is manufactured in the form of gear transmission in most cases. So it is customary to regard reducer, gearbox and reducer as one thing. Unless there are special requirements in practical applications, there are only slight differences. For example, reducers are used in elevators, and gearboxes are used in cars.
