Definition of a ball screw and its benefits! A ball screw, which was originally known as an antifriction nut, is some kind of a mechanical device which is used to convert rotational motion into a linear one. This mechanical device tends to feature a long threaded shaft with ball bearings in order to handle and withstand a substantial amount of stress and weight, all while, at the same time, minimizing friction. A typical Hiwin ball screw consists of both a screw as well as a nut. There exist helical indentions which are formed on the outside of the screw and nut, letting ball bearings to roll between them quite easily. Each time the ball screw rotates, the ball bearings would travel back to the return system before changing any direction.
This device, known as the ball screw, was invented by a man named Rudolph G. Boehm in the last years of the decade of 1920s. Cut to today, these devices are known to be used in multiple manufacturing applications, many of which include missiles, airplanes, 3D printers, automobiles, and various other machines. If you are thinking about contacting Hiwin ball screw manufacturers and using ball screws in manufacturing applications for your business, then it is important that you know about the pros of this particular device. But before we dive into the benefits of ball screws, let’s learn the difference between ball screws and lead screws.
Difference between ball screws and lead screws
It is easy to mistake ball screws for lead screws as there are a lot of similarities between the two when it comes to appearance. But, it is only ball screws that have ball bearings inside the nut. If we talk about lead screws, the nut is devoid of the presence of any ball bearings and it doesn’t even actively roll. On the other hand, ball screws consist of a nut in which ball bearings roll in order to support the load and reduce friction. Now that you know the difference between the two, let’s take a look at the benefits of ball screws. Efficient: Ball screws are known to offer quite a high level of mechanical efficiency. Statistics prove that ball screws are around 90 per cent efficient, which alludes to the fact that they convert nine-tenths of the rotational motion into linear one successfully. Continue Reading…
