The difference between planetary gear reducer and cylindrical gear reducer

Planetary gear reducer and cylindrical gear reducer are two different mechanical transmission devices. They have obvious differences in transmission form, transmission efficiency, noise and price.A detailed comparison of these two reducers will be made below so that users can choose the appropriate reducer type according to actual needs.

1. Different transmission forms

The planetary gear reducer is a reduction device realized through a planetary gear train, and its transmission form is a planetary gear train transmission.Planetary gear train transmission has the advantages of large transmission ratio, small size, and high transmission efficiency, so it is widely used in many industrial fields.In contrast, the transmission form of the cylindrical gear reducer is cylindrical gear transmission, and reduction is achieved through a pair of meshing cylindrical gears.This transmission form is relatively common, but the transmission ratio and efficiency are relatively low.

2. Different transmission efficiencies

The transmission efficiency of planetary gear reducers is generally above 90%, while the transmission efficiency of cylindrical gear reducers is lower, generally around 85%.This difference is mainly due to the special transmission form of the planetary gear train, which allows the reducer to maintain high transmission efficiency even when running at high speeds.In contrast, cylindrical gear reducers lose efficiency when operating at high speeds.

3. Noise is different

Because the planetary gear reducer adopts planetary gear train transmission, its internal gears will not generate lateral force during operation, so it has lower noise.In contrast, cylindrical gear reducers generate larger lateral forces during operation, resulting in louder noise.Therefore, in places where low noise is required, such as hospitals, precision machinery and other fields, planetary gear reducers should be given priority.

4. Prices are different

The manufacturing cost of planetary gear reducer is relatively high, so the price is relatively expensive.The manufacturing cost of cylindrical gear reducers is relatively low, so the price is cheaper.However, considering that the planetary gear reducer has the advantages of high transmission efficiency and low noise, for some occasions that require a high-quality reducer, it may be more economical and reasonable to choose a planetary gear reducer.

In summary, planetary gear reducers and cylindrical gear reducers each have their own advantages and disadvantages, and users should weigh them based on actual needs when choosing.If you need a reducer with high transmission efficiency, low noise, and high quality, you should give priority to a planetary gear reducer; if you have low requirements for transmission efficiency, noise, etc., and your budget is relatively limited, you can choose a cylindrical gear reducer.
