[0002] Ball screws are the most commonly used transmission elements in tool machinery and precision machinery.

They also have the characteristics of high precision, reversibility and high efficiency. Due to their very low friction resistance, ball screws are widely used in various industrial equipment and precision instruments.

[0003] Some existing mechanical ball screws generally require regular maintenance after a period of use. However, as the intensity of production tasks increases, the frequency of device operation will also increase. At this time, a fixed maintenance cycle cannot guarantee the stability of device operation, which is inconvenient. Utility Model Content
