Working principle and classification of reducer

I often ask my friends what is the working principle of the reducer? In fact (reducer) reducer in short is to increase torque and reduce speed! The reducer is generally used for the transmission equipment with low speed and high torque. The motor, internal combustion engine or other high-speed power is meshed with the large gear on the output shaft through the gear with less teeth on the input shaft of the reducer. The ordinary reducer also has several pairs of gears with the same principle to achieve the ideal deceleration effect. The ratio of the number of teeth of large and small gears is the transmission ratio. Reducer products are widely used. Food and light industry, electric machinery, construction machinery, metallurgical machinery, cement machinery, environmental protection machinery, electronic and electrical appliances, road construction machinery, water conservancy machinery, chemical machinery, mining machinery, transportation machinery, building materials machinery, rubber machinery, petroleum machinery and other industries. The following are the commonly used reducer categories: 1. Helical gear reducer with hard tooth surface 2. Small and micro gear reducer 3. Cylindrical gear reducer with hard tooth surface 4. Planetary gear reducer (servo planetary reducer) 1) ring gear is fixed, sun gear is active and planet carrier is passive. It can be seen from the demonstration that this combination is speed reduction transmission, the transmission ratio is generally 2.5 ~ 5, and the steering is the same. Soft tooth surface reducer 5, three ring reducer 6, crane three in one reducer 7, worm gear reducer 8, shaft mounted hard tooth surface reducer 9, continuously variable transmission, hard tooth surface helical gear reducer. I believe everyone knows imported sew reducer, Sumitomo reducer of Japan, Siemens Flanders reducer, Burton reducer, maichuan reducer, Nord reducer, etc. The small and micro gear reducer is 6W to 4000W, which can be called small and micro gear reducer. For example, the well-known ones include Taiwan Chengbang reducer, Shiyuan reducer, Haoxin reducer, Dongli reducer, maichuan reducer, Mingchun reducer and Wanxin reducer. The service of maichuan reducer is better than others.
