      Shaft End Of Ball Screw Is Introduced
      Jan 02, 2020

      Ball screw pair as a precise, efficient, sensitive transmission components, in addition to the use of high precision screw, nuts and ball, but also should pay attention to the selection of high axial stiffness, friction torque, high operating accuracy of the bearing.

      Ball screw is the most commonly used transmission element in tool machinery and precision machinery. It is composed of screw, nut, steel ball, preload plate, reverse device and dustproof device.Its main function is to convert rotating motion into linear motion, or to convert torque into repeated axial force, with high precision, reversibility and high efficiency.

      The mounting mode of the ball screw has great influence on the bearing capacity, rigidity and maximum speed of the ball screw pair.The ball screw nut pair shall meet the following requirements during installation:

      1, the ball screw nut pair relative to the table can not have axial channeling;

      2. The center of the socket hole shall be concentric with the installation axis of the lead screw;

      3. The center line of ball screw nut pair shall be parallel to the corresponding guide rail;

      4. It is convenient for gap adjustment, pre-tightening and pre-stretching.
