What is it in the machines?

The cylinder screw is a mechanical device that converts the rotary movement to linear movement. They are mainly known as cylindrical screws, which are very similar to construction than balls. The roller screws consist of three main components that are nuts, rollers and shafts. The rollers, shafts and the inside of the nut are threads, so that the nut rotation creates a linear movement inside the screw. The cylinder screws are more expensive, better alternative to ball screws. Their biggest difference lies in the area between the walnut and shaft case. Instead of having threaded rollers, it will have a ball screw of the ball. These balls work very much like the cylinder fibers, because their rotation pushes the shaft in and out of the nut. The roller screws are usually more expensive than the ball screws, mainly because of their increased longevity, quality, accuracy and maximum capacity. On the outside lies a matrix case, which is often connected to a motor or engine that rotates it. The case itself will often beserve as an electrical engine fitting. This makes the device much more compact and efficient, allowing it to be used in a wider range of applications.

The interior of the nuts is an inner fiber that comes into contact with the corresponding cylinder fibers. There are more cylinders inside each cylindrical screw, usually enough to fill the gap between the matrix and the shaft. The number and size of these rollers differ depending on the size of the controller. Regardless of the size, all the threading rollers allow the contact between the matrix and the Shaft. When the walnut cover turns, the cylinders move around the shaft; As a result, they are often referred to as orbital rollers.

The

shaft is usually larger than rollers and moves linearly. Like other components, the shaft also has a thread that can connect with the rollers. How to turn the inner fiber of the nut cover, as well as rollers. The rotation of these rollers "push" the shaft fiberthat moves it forward or back. The direction in which the shaft moves depends on the rotary direction of the matrices.
