Sizing and calculating linear guide, ball screw, reducer, coupling, rack&pinion and other machine components and parts.
Achieving precise and efficient horizontal movement in machinery and automation systems often requires careful selection of essential components. Among the critical components are ball screws, planetary reducers, and servo motors, which work together to ensure smooth and accurate motion. In this article, we will explore the principles behind selecting the right ball screw, planetary reducer, … Read more
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.
Belt pulley driven is not my favorite method for linear motion. Because this is the drive method with the weakest positioning accuracy. However, if a cheap and high speed method is required, belt pulley is the most suitable method.
I’m using Yaskawa SigmaJunmaSize+ and THK Life Calculator applications for my all calculations.
Target values;
Max Speed: 1000mm/sec
Stroke : 2000mm
Let’s start by calculating linear guides as usual. This time we have an asymmetric gravity point. There is also a high speed request, which is specified as 1000 mm / second. Therefore, we will use the SHS series, which is more suitable for high speed. You can use these products either externally or assembled in a linear module.
Next is the calculation of the system that will be driven by rack and pinion. Usually this drive system is used in marble, wood, laser cutting and plasma machines.
Also I’m still using Yaskawa SigmaJunmaSize + and THK Life Calculator applications.
Target values;
Max Speed: 500mm/sec
Stroke : 2000mm
We’ll start with linear guide sizing again.
