How To Size Planetary Reducer

In my previous posts, I said that I will explain the planetary reducer selection, later.As you know, planetary gearboxes have many types produced according to need.Helical gear planetary reducers can be used for precise positioning and low operating noise, and straight gear planetary reducers can be used for standard applications.Of course, these definition classifies reducers very simply. Because there are dozens of subspecies according to their use.For this article, let’s assume that we know the output torque, the speed of the system and the need for positioning precision.

We made the calculation for the system with Yaskawa SigmaJunmaSizer + and let’s assume that the system needs i:7 ratioand the maximum torque required by the system is 67Nm ( servo output 6,57Nm).
