Introduction Ball screws are mechanical devices used to convert rotational motion into linear motion. They consist of a threaded shaft and a nut that contains a series of recirculating balls. When the shaft rotates, the balls move along the thread, causing the nut to move linearly. Ball screws are widely used in various industrial applications due to their high efficiency, accuracy, and reliability. They are commonly used in machine tools, robotics, and aerospace. Basic Principles of Ball Screw Operation The mechanism of ball circulation is the key to the operation of ball screws. The balls are recirculated through a series of channels between the nut and the screw shaft. As the screw rotates, the balls are forced to move along the channels, causing the nut to move linearly. There are two types of ball screws: precision and rolled. Precision ball screws have a ground thread and are used in applications that require high accuracy and precision. Rolled ball screws have a machined thread and are used in applications that require lower accuracy and precision. Design and Analysis of Ball Screws The design and analysis of ball screws involves several parameters, including the load capacity, the ball screw pitch, and the ball screw diameter. The load capacity is the maximum load that the ball screw can withstand without experiencing deformation or failure. The ball screw pitch is the distance between adjacent threads on the screw shaft. The ball screw diameter is the diameter of the screw shaft. Application of Ball Screws Ball screws are widely used in various industrial fields, including machine tools, robotics, and aerospace. In machine tools, ball screws are used to provide high-speed and high-precision movement. In robotics, ball screws are used to provide accurate and smooth movement. In aerospace, ball screws are used in various applications, including aircraft landing gear and satellite positioning systems. Conclusion Ball screws are essential mechanical devices used in various industrial applications. This thesis provides a comprehensive review of the design, analysis, and application of ball screws. The basic principles of ball screw operation, the design and analysis of ball screws, and the application of ball screws in various industrial fields are discussed in detail.
