Ball screw difference 1 --- ordinary life. Rolling friction surface damage is much smaller than sliding friction, so when cleaning, lubricating and other conditions are met, the ball screw shaft, ball screw sustain life is much higher than the trapezoidal screw. 2 --- self-locking. Self-locking and transmission efficiency is generally inversely proportional, therefore, almost no self-locking ball screw, lead screw and a certain self-locking (depending on the size of the lead angle and the working surface roughness). Ball is a very high precision parts, can accurately determine the coordinates of the location of the table, buy a ball screw to convert rotary motion to linear motion, but also to transfer some power, so in terms of accuracy, strength and abrasion and other aspects of a very high demand. Ball processing must therefore careful consideration from the rough to the finished product of each procedure, in order to improve its precision. Ball rolling screw and roller screw justice into two categories. Ball and roller screw In contrast, low friction ball screw Hubei, high transmission efficiency, accuracy is also high, so that the more commonly used, but its manufacturing process more complicated.
