The difference between planetary reducer and ordinary reducer

Planetary reducers and ordinary reducers are two different types of reducers. They are different in structure, working principle, application scenarios, etc.This article will introduce in detail the differences between planetary reducers and ordinary reducers so that readers can better understand the characteristics and application scope of these two reducers.

First of all, from a structural point of view, the planetary reducer is mainly composed of planetary gear, sun gear, internal ring gear, planet carrier and other parts.It has compact structure, high transmission efficiency, large reduction ratio, and small volume and weight.In contrast, ordinary reducers usually consist of parallel-axis cylindrical gears, worm gears, worms and other parts. Their structures are relatively simple, but their transmission efficiency is low and their reduction ratios are also small.

Secondly, from the perspective of working principle, the planetary reducer adopts the working principle of the planetary gear train, that is, deceleration is achieved through the mutual motion of the planetary gear, sun gear and internal ring gear.The ordinary reducer achieves deceleration through the mutual meshing of gears, and its working principle is relatively simple.

In terms of application scenarios, planetary reducers are suitable for applications that require larger reduction ratios and high efficiency, such as robots, packaging machinery, printing machinery, etc.Ordinary reducers are suitable for occasions that do not require high reduction ratios and are more sensitive to cost, such as conveying machinery, textile machinery, etc.

In addition, there are certain differences in performance between planetary reducers and ordinary reducers.The transmission efficiency of planetary reducer is usually higher than that of ordinary reducer, and its reduction ratio is also larger, so it can provide greater output torque under the same power.At the same time, the design of the planetary reducer is more compact, with relatively small size and weight, making it easy to install and use.The design of ordinary reducers is relatively simple and the manufacturing cost is low, but its transmission efficiency is relatively low, so it consumes more energy during use.

To sum up, there are obvious differences between planetary reducers and ordinary reducers in terms of structure, working principle, application scenarios and performance.In actual applications, the appropriate reducer type should be selected according to specific needs to achieve optimal performance and economic benefits.
