  • What is ball screw and nut assembly in a CNC machine?
    May 08, 2024
    Here is Shuntai’s answer for you: Ball screw and nut assemblies in CNC machine tools are key components used to transmit rotational motion and convert it into linear motion. The ball screw is a mechanical transmission device composed of a screw and a ball nut. Its working principle is to engage the threads on the screw with the balls on the ball nut, and drive the ball nut to move axially along the screw during rotation. There are many balls inside the ball nut. These balls roll in the ball groove, which can reduce friction resistance, improve transmission efficiency, and have high rigidity and positioning accuracy. Ball screws are widely used in CNC machine tools, automation equipment, precision machinery and other fields. The nut is a component used with the ball screw and is usually made of metal material. The nut has internal threads that match the ball threads and mate with the ball screw threads. When the ball screw rotates, the nut moves along the screw axis, achieving linear motion. The design and processing quality of the nut have an important impact on the accuracy and life of the ball screw transmission. Ball screw and nut assemblies are often used in the feed system and positioning system of CNC machine tools to ensure that the machine tool has high stability, positioning accuracy and fast performance during processing. Their use can improve the processing efficiency and accuracy of machine tools, while reducing friction and wear between moving parts and extending the service life of machine tools.

Ball screw transmission efficiency: The transmission efficiency of the ball screw is usually above 90%, which may vary depending on the specific ball screw type and usage conditions. The higher the transmission efficiency, the smaller the difference between output torque and input torque. 3. Ball screw dynamic parameters: The dynamic parameters of the ball screw include pitch, lead and ball diameter. Pitch refers to the distance the ball screw moves axially during one revolution of the nut. Lead refers to the angle of rotation required for a ball screw to move axially for one revolution. Ball diameter refers to the diameter of the balls used in the ball screw. Generally speaking, the following formula can be used to calculate the torque of a ball screw: Torque = (input torque × transmission efficiency) / (pitch × 2π) Among them, the input torque and transmission efficiency are known parameters, the pitch represents the axial movement distance of the ball screw, and 2π represents the rotation angle of one revolution. Please note that the units in the above formula must be consistent, for example, the unit of torque is Newton·meter (N·m) and the unit of pitch is meter (m). It should be noted that the torque calculation of the ball screw is a simplified model. In actual applications, some other factors may need to be considered, such as the loading conditions of the ball screw, friction and wear, etc., which may affect the torque.

  • What is the difference between ball screw drive and lead screw drive?
    Apr 18, 2024
    Ball screw transmission and lead screw transmission are two common mechanical transmission methods. The differences between them are as follows: 1. Working principle: In screw transmission, the thread cooperation between the threaded screw and the nut causes the nut to move along the axial direction of the screw when the screw rotates. In ball screw transmission, the thread surface of the threaded screw is supported by balls. Under the action of the balls, the ball screw has higher efficiency and greater load capacity. 2. Efficiency and precision: The efficiency of ball screw transmission is usually higher than that of screw transmission because the rolling friction of the balls is smaller than the sliding friction of the thread. In addition, ball screw transmission has high positioning accuracy and repeatable positioning accuracy, and is suitable for applications that require higher accuracy. 3. Load capacity: Due to the rolling effect of the balls, the ball screw drive has a greater load capacity than the screw drive. Ball screw drives can generally handle higher axial and inclination loads. 4. Friction and wear: The rolling friction of the ball screw drive is smaller, so there is less frictional heat and wear, making it more reliable at high speeds and long periods of operation. In general, ball screw transmission has higher efficiency, greater load capacity and better accuracy than screw transmission, but its manufacturing cost is higher. Therefore, the choice of ball screw drive or lead screw drive should be decided based on the requirements and budget of the specific application.
