Are there any resources provided to supplement the English teaching on ball screws?

Ball screw teaching in English Ball screw is a kind of mechanical component that converts rotary motion into linear motion. It has a high precision and efficiency, and is widely used in various industries such as machinery, aviation, and aerospace. Here we will introduce the basic knowledge and working principle of ball screw. 1. Basic knowledge of ball screw Ball screw is composed of screw, nut, steel ball, preloading device and other components. The screw is a cylindrical rod with a spiral groove on the outer surface, and the nut is a block with a spiral groove on the inner surface. The steel ball is sandwiched between the groove of the screw and the nut, and the preloading device is used to maintain the contact between the screw and the nut. 2. Working principle of ball screw When the screw rotates, the steel ball moves along the spiral groove and drives the nut to move linearly. The preloading device ensures that the steel ball is always in contact with the groove of the screw and the nut, so that the motion is stable and efficient. Ball screw has many advantages, such as high precision, high efficiency, low friction, and high rigidity. It is widely used in CNC machine tools, industrial robots, and precision instruments. In addition, the ball screw can also be used in combination with a motor and a reducer to form a linear motion system, which can realize precise positioning and movement control.
