A reducer is a mechanical device that can reduce the rotational speed of a high-speed rotating power source (such as a motor) and increase the output torque at the same time.
A reducer is usually composed of main components such as a housing, gears (or worm and worm gears), shafts, bearings, and oil seals. The housing is used to support and protect the internal parts; gears (or worm and worm gears) are the core components to achieve speed reduction and torque increase; shafts are used to install and support the gears; bearings reduce rotational friction; oil seals prevent lubricating oil leakage.
There are many types of reducers, and the common ones are:
1. Planetary reducer: It has the characteristics of small size, light weight, high load capacity, high transmission efficiency, and smooth operation. It is suitable for application scenarios with high precision and high torque.
2. Worm and worm gear reducer: It has a large transmission ratio, stable transmission, low noise, but relatively low transmission efficiency. It is often used in occasions of low speed and high torque.
3. Gear reducer: It has a simple structure, high reliability, and can adapt to various working conditions, but the precision and transmission efficiency are slightly lower than those of the planetary reducer.
Different types of reducers have their own characteristics in terms of performance, precision, transmission efficiency, load capacity, etc. Users can choose the appropriate type of reducer according to specific usage requirements.
