ReducerGenerally used for low-speed and high torque transmission equipment, the electric motor, internal combustion engine, or other high-speed power is reduced by meshing a gear with fewer teeth on the input shaft of the reducer with a large gear on the output shaft. Ordinary reducers 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.

Reducerclassification

The reducer plays a role in matching speed and transmitting torque between the prime mover and the working machine or actuator, and is a relatively precise mechanical device. The purpose of using it is to reduce the speed and increase the torque. It has a wide variety of types, different models, and different types have different purposes. There are many types of reducers, which can be divided into gear reducers, worm reducers, and planetary gear reducers according to the transmission type; According to different transmission stages, it can be divided into single-stage and multi-stage reducers; According to the shape of gears, they can be divided into cylindrical gear reducers, bevel gear reducers, and cone cylindrical gear reducers; According to the arrangement of transmission, it can be divided into expansion type, diversion type, and coaxial type reducers.

Reducercharacteristic

The main feature of a worm gear reducer is its reverse self-locking function, which allows for a larger reduction ratio. The input shaft and output shaft are not on the same axis or plane. But generally, the volume is large, the transmission efficiency is not high, and the accuracy is not high. The harmonic drive of harmonic reducer utilizes the controllable elastic deformation of flexible components to transmit motion and power. It has a small volume and high accuracy, but the disadvantages are limited service life of the flexible wheel, lack of impact resistance, and poor rigidity compared to metal parts. The input speed cannot be too high. The advantages of planetary gearboxes are compact structure, small return clearance, high precision, long service life, and the ability to achieve a large rated output torque. But the price is slightly higher. Gear reducers have the characteristics of small size and high torque transmission. Gear reducers are designed and manufactured based on a modular combination system, with a wide range of motor combinations, installation forms, and structural schemes. The transmission ratio is finely graded to meet different operating conditions, achieving mechatronics integration. Gear reducers have high transmission efficiency, low energy consumption, and superior performance. Cycloid pinwheel reducer is a transmission model that adopts the principle of cycloidal pinwheel meshing planetary transmission. It is an ideal transmission device with many advantages, wide applications, and can operate in both forward and reverse directions.

Reducerrole

1. Reduce speed while increasing output torque. The torque output ratio should be calculated by multiplying the motor output by the reduction ratio, but it should be noted not to exceed the rated torque of the reducer;

2. Deceleration also reduces the inertia of the load, which is the square of the reduction ratio.
