Ball screw is the most commonly used transmission element in tool machinery and precision machinery. Its main function is to convert rotary motion into linear motion or torque into axial repetitive force, which has the characteristics of high precision, reversibility and high efficiency. Ball screw is widely used in various industrial equipment and precision instruments because of its low friction resistance.
Ball screw is composed of screw, nut, steel ball, precompression, inverter and dustproof device. Its function is to transform rotary motion into linear motion, which is the further extension and development of Acme screw. The significance of this development is to change the sliding motion of bearings into rolling motion.
Linear slider can be divided into roller linear slider, cylindrical linear slider and ball linear slider, which are used to support and guide moving parts and make reciprocating linear motion in a given direction. According to the different nature of friction, linear motion guide can be divided into sliding friction guide, rolling friction guide, elastic friction guide and fluid friction guide.
The function of linear guide rail motion is to support and guide the moving parts to do reciprocating linear motion in a given direction. According to the different nature of friction, linear motion guide can be divided into sliding friction guide, rolling friction guide, elastic friction guide and fluid friction guide. Linear bearing is mainly used for automation machinery, such as machine tools, bending machines and laser welding machines imported from Germany. Of course, linear bearing is used with a straight axis. Linear guide rails are mainly used in mechanical structures with high precision requirements. Rolling steel balls are used to replace the intermediate medium between the moving element and the fixed element of the linear guide rail.
