They are used in a wide range of applications, including machine tools, robots, aircraft, and automotive systems. Ball screws offer many advantages over other types of screws, such as high efficiency, high precision, and low wear. This paper provides a brief overview of ball screws, their construction, working principles, and applications. Construction: A ball screw consists of a screw shaft, a nut, and a set of balls. The screw shaft has a thread profile that matches the profile on the inside of the nut. The balls are located between the screw shaft and the nut, and they roll along the thread profile as the screw shaft rotates. The rolling action of the balls reduces friction and wear, making the ball screw more efficient and durable than other types of screws. Working Principles: Ball screws work on the principle of recirculating balls. As the screw shaft rotates, the balls roll along the thread profile and are carried by the nut. The balls are then forced back to the starting point by a return tube located in the nut. This recirculating action allows the ball screw to achieve high efficiency and precision. Applications: Ball screws are widely used in applications that require high precision and efficiency, such as machine tools, robots, and aerospace systems. They are also used in automotive systems, such as power steering and suspension systems. Ball screws are preferred over other types of screws in these applications because of their high accuracy, low wear, and high efficiency. Conclusion: Ball screws are mechanical devices used to convert rotational motion into linear motion and vice versa. They offer many advantages over other types of screws, such as high efficiency, high precision, and low wear. Ball screws are widely used in applications that require high precision and efficiency, such as machine tools, robots, and aerospace systems. They are also used in automotive systems, such as power steering and suspension systems., 3. 滚珠丝杠的寿命缩短，需要更频繁地更换,具体的计算方法需要根据实际情况进行确定,它的夹头中装有滚珠，当旋转夹头时，滚珠会自动收缩，从而夹住物品,滚珠丝杠是一种重要的传动元件，广泛应用于数控机床、自动化生产线、机器人、航空航天等各个领域,一般分为C0、C1、C2等等级，可以通过精度等级进行区分
