Ball screws ensure the reliability and sustainability of linear motion, but the requirements for accuracy vary depending on specific situations. The smaller the gap between the axes, the higher the accuracy can be ensured during directional transmission. After all, it is a linear motion of the screw, so to ensure its continuous effectiveness, it is necessary to ensure high continuity during reverse transmission. When adjusting the gap of the ball screw, there are a few points to note.

1. Improve the rigidity of the rod pair

Generally, the adjustment method using double nuts is considered, which allows for fine control of the adjustment gap within a small range. However, in this case, it requires that the stiffness of the rod pair is sufficiently high.

2. Adjust the preload force

Excessively large or small preload will affect the magnitude of the driving torque, which in turn directly impacts efficiency and mechanical service life. Therefore, when adjusting the preload, it is essential to consider the maximum axial load, so as to ensure that adjusting the preload to control the clearance does not affect the service life and efficiency of the ball screw.
As a transmission component, ball screws are highly recommended for use in various industries due to their low friction resistance and high positioning accuracy. Especially in modern industry, where precision requirements are relatively high, this type of transmission component is popular. Additionally, there are many types of this transmission component, which can be well adapted to various applications. The comprehensive excellent characteristics of ball screws mainly include the following points.

• High transmission efficiency
  The significant reduction in frictional resistance has greatly improved the transmission efficiency of this transmission component. The main reason is the high motion efficiency of the rolling balls between the screw shaft and the screw nut during rolling. This also results in significant electricity savings.
• High precision
  Ball screw assemblies are produced as an integrated part of mechanical equipment, ensuring precision in grinding, assembly, and inspection environments during production. The control over humidity and temperature is also meticulous, resulting in high precision.
