Before introducing the first-stage planetary reducer and the second-stage planetary reducer, let's take a look at what the series of the planetary reducer means.The number of stages of the planetary reducer refers to the number of sets of the planetary gear frame inside the reducer. From the internal structure diagram of the planetary reducer, it can be seen that the internal gear frame structure of the planetary reducer is mainly composed of an inner ring gear, a planetary gear and a sun gear. In some working situations, because a set of planetary gears cannot meet relatively large transmission requirements, it is necessary to increase the planetary gear carrier to meet the required transmission ratio at this time.The reducers on the market are generally divided into 3 levels, and other types of reducers are relatively large, and the precision is not as good as that of planetary reducers.
The first-stage planetary reducer refers to a reducer with a set (a set of planetary gear, sun gear, and inner ring gear)
The two-stage planetary reducer refers to a reducer with two sets (a planetary gear, a sun gear, and an inner ring gear)
The difference between a one-stage planetary reducer and a two-stage planetary reducer
1. The number of planetary gears inside the reducer is different
The first-stage planetary reducer has only one set of planetary gear sets, and the second-stage planetary reducer has two sets of planetary gear sets.
2. The reduction ratio of the reducer is different
Due to the increase in the number of sets of planetary gears inside the planetary reducer, the length of the two-stage planetary reducer is longer than that of the one-stage planetary reducer.
4. Different efficiency
The efficiency of the two-stage planetary reducer is lower than that of the one-stage planetary reducer.
5. The transmission ratio is different
The transmission ratio of the two-stage planetary reducer is larger than that of the one-stage planetary reducer.
What is the difference between a one-stage planetary reducer and a two-stage planetary reducer?
In the final analysis, the difference between the first-stage planetary reducer and the second-stage planetary reducer is the difference in the number of gear sets. The working efficiency of the second-stage planetary reducer is lower than that of the first-stage planetary reducer.Furthermore, there is a difference in length. The second-stage planetary reducer is longer than the first-stage planetary reducer.The second is the difference in the rotation ratio between the two. Compared with the first-stage planetary reducer, the two-stage planetary reducer has a larger rotation ratio than the first-stage reducer.
Before we choose, we must clearly understand which model, which type, and which level of planetary reducer we need. Different models and different types of reducers have their own characteristics, and the motor cannot be arbitrarily reduced. Machines have reached a match, so you must be careful when choosing.Well, this is the end of the content sharing about the reducer in this issue. If you need it, please consult.
