Basic classification and characteristics of commonly used reducers

The reducer is basically divided into the following types

1. Transmission type: it can be divided into worm reducer, gear reducer and planetary gear reducer;

2. Different transmission stages: it can be divided into multi-stage reducer and reducer;

3. Gear shape: can be divided into bevel gear reducer, cylindrical gear reducer

4. Transmission arrangement: it can be divided into sub-flow, coaxial and unfolding reducers.

main features

Worm gear reducer: Its characteristic is that this type of reducer has the function of reverse self-locking and can have a relatively large reduction ratio. The output shaft and the input shaft are not on the same axis or on the same plane. of. However, the general worm gear reducer is relatively large, the transmission power is not high, and the precision is not high.

Harmonic reducer: It uses the controllable elastic deformation characteristics of flexible elements to transmit motion and power. It is small in size, but at the same time, its precision is still high, but the defects are also obvious, that is, the flexible wheel does not. Impact resistance, its life is limited, metal parts are poorer than rigidity, and the input speed cannot be too high.

Planetary reducer: The advantages of the planetary reducer are that the structure is relatively compact, the precision is relatively high, the gap between the return strokes is relatively small, the service life is very long, and the extra output torque can be made very large. But the price is too expensive.

Gear reducer: Although the volume of the gear reducer is small, its transmission torque is large, which is its characteristic. It is designed and manufactured on the basis of the combined system of modules, so there are many installation methods, motor combinations and structural schemes. It can satisfy many kinds of application situations and truly complete the integration of electromechanical. The gear reducer has high transmission power and low energy consumption, so its performance is very superior.

Cycloidal pinwheel reducer: It selects a transmission model based on the principle of cycloid pin-tooth meshing planetary transmission. It is a transmission device that is ideal for right and wrong. It has a wide range of uses, has many advantages, and can work in both positive and negative directions.
