The planetary reducer is a kind of machine tool that has appeared in the eyes of the public with the deepening of people’s understanding of the planetary reducer, the strengthening of the structure, and the improvement of the manufacturing process in recent years. Therefore, the planetary reducer has been more and more widely used. However, for the rotation ratio distribution of the planetary reducer, since the rotation ratio of the single-stage gear reducer is not greater than 10, when the requirement for the total rotation ratio exceeds this value, a 2-stage or multi-stage reducer is required. At this point, we need to consider the reasonable distribution of the rotation ratio at all levels.
It should be known that if the rotation ratio of the planetary reducer is improperly distributed, it will affect the shape and size of the reducer and the size of the carrying capacity. The correct rotation ratio distribution should be as follows: make the load capacity of each rotation stage close to the same value, the external size and mass of the reducer are small, make the rotation inertia small, and the oil immersion depth of the large gear in each rotation stage is roughly the same.
When it comes to planetary reducers, the words “high torque and impact resistance” should first come to mind, which is also the intuitive feeling it brings to every user who has used planetary reducers. The structure of the planetary reducer is superior to the traditional reducer. The traditional reducer only relies on a small amount of point contact between two gears to form the driving force, and all the carrying capacity is concentrated on the contacted small number of gear surfaces. Highly sensitive to friction and breakage. However, the planetary reducer has six large gear contact surfaces with a 360-degree uniform load, and multiple gear surfaces jointly and evenly bear the instantaneous impact load, so that the planetary reducer can withstand relatively high torque pressure.
Furthermore, it must be mentioned that it is small in size and light in weight. The design of the traditional reducer has many sets of large and small gears offset to the interlaced drive deceleration, because the reduction ratio must double the number of two different gears, and the size data between the gears We also need to be able to maintain a certain distance, which also causes the traditional reducer to be too large and bulky. The structural analysis of the planetary reducer can be studied and repeatedly connected according to the number of segments required by the user’s personal life at the same time, and can effectively realize the need for multiple segments to be completed separately.
