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 inertia SFU ball screw, should reduce the number and quality of SFI ball screw moving parts, using high-strength aluminum alloy, carbon fiber reinforced plastic and other high-speed moving parts to reduce the weight. Surrounding rolling linear guide, bearing etc. should also meet the requirements of speed. Only in this way, in the high-speed servo motor driven SFS ball screw, ball screw shaft to get high-speed, efficient expected results. The main parameters of the thread 1) the outer diameter d (large diameter) (D) - with the external thread crests coincide with the diameter of an imaginary cylindrical surface - also known as nominal diameter 2) the inner diameter (diameter) d1 (D1) - and outer coincide with the end of the thread imaginary cylindrical surface diameter, as the risk of cross-section of the strength calculation to calculate the diameter of 3) in diameter d2-- imaginary cylindrical surface at a diameter equal to the width between the teeth and tooth thickness in the axial section, approximately equal The average diameter of the d2≈0.5 threaded (d + d1) 4) P-- two adjacent teeth pitch diameter cylindrical surface on the bus between two points corresponding to the axial distance 5) lead (S) - the same helix two teeth in the axial diameter cylindrical surface corresponding bus distance between two points on the adjacent ball screw SFI | Ball screw | Korea Taiwan transmission machinery provided by the Dongguan City, Transmission Machinery Co., Korea and Taiwan.
