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).

Basics of Ball Screw Production

Ball screw production is a process that requires high precision.Many manufacturers have transferred almost a hundred years of metal machining experience to ball screw production.However, there are companies that have started this business recently.Especially new companies have lower budgets, so they choose custom ball screw production.As it is known, screw shaft types have classes such as C0, C1, C3, C5, C7, C8 and C10 (also indicated by the letter T) according to their production quality.These classes give information about whether ball screws are of ground type or rolled type.

Introduction of Ball Transfer Units

 

Defination of Ball Transfer Units

Transfer ball units are machine equipment used in the machinery industry today. Their task is to transfer the loads placed on them with the rotating ball inside.They are generally used in conveyors, in the feeding / part output sections of the machines and in the areas where packaging work is performed.They are produced in three types: ball supported, spring supported and pneumatic supported.Depending on the usage conditions, there are different subtypes as light type, medium type and heavy type.In some cases they are also used as castors and wheels.Some companies also name these products as ball transfer bearings.You can see an image of the product’s outer view in the image below.
