As a further extension of the development drive sliding screw and ball screw due to its high efficiency, low temperature, high-precision, high speed, high rigidity, reversible, long life, low power consumption, synchronization, high sensitivity, without gaps, maintenance and simple and has been widely used in modern CNC machine tool feed servo mechanism, in order to meet the high feed rate of CNC machine tools, high precision, high stability and rapid response requirements, must be selected ball screw, and make the necessary The check calculations. Ball choices include the contents of its precision selection, sizes (including lead and public Cheng diameter), and several other aspects of supporting way. Ball screw with a dynamic load carrying capacity or static load rating to indicate the ball screw in the center of the design process is generally determined by dynamic load rating of ball screw sizes, but to withstand compressive loads on slender accounting for the stability ball screw bar; for high speed ball screw production, large ball screw support distance for critical speed check; for high precision ball screw for rigidity checking; CNC machine tools, accounting needs of its moment of inertia; the whole closed-loop system supplier of ball screw, to be accounted for its resonant frequency. Ball peripheral component parts of linear servo system speed is a systems engineering. Ball Screw bearing stiffness and precision to improve the critical speed installation Nc, improve smooth movement, reduce noise effects can not be ignored. In order to reduce the inertia, the moving parts should be reduced quantity and quality, the use of high-strength aluminum alloy, carbon fiber reinforced plastic or the like to reduce the weight of high-speed moving parts. Surrounding rolling linear guide, bearing etc. should also meet the requirements of speed. Only in this way, in the high-speed servo motor drive, the ball screw shaft to get high-speed, efficient expected results.
