Selecting Rack and Pinion According to Machine Types.

Q7 Pinion 1

Many machines manufactured today have a rack and pinion in the drive system.Whether these products are straight or helical, they are very important because of their positioning task.These drive systems are preferred in wood router, metal machining center or laser cutting machines, especially in the X-Y axis.

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.

Vertical Linear Motion With Rack&Pinion – 1

Linear Guide, Rack&Pinion , Reducer and Servo Motor Sizing for Vertical Motion

Now we have started the calculation of vertical motion. When designing the machine, you need to know that the coefficient of gravitational acceleration will be added to the vertical linear motion calculations.We should also pay more attention to inertia ratio between load and sero motor.
