Ball is a highly precision ball screw plant parts can accurately determine the coordinates of the location of the table, the rotary motion into linear motion, but also to deliver a certain power sale ball screw, so in terms of accuracy, strength and abrasion resistance, etc. have 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 Ball terms compared with the roller screw purchase, friction, high transmission efficiency, accuracy is also high, so that the more commonly used, but its manufacturing process more complicated. Outer circulation ball screw nut ball circulation mode Press Back when the main cover type, tube and spiral trough. Unlike linear guide, it's common outer loop mode (a) cap formula; (b) intubation; (c) screw cap type trough is processing a longitudinal hole in the nut, a ball return passage, On both ends of the cover nut ball backhaul opened mouth, the ball will enter the return pipe, form a cycle. Intubation, use it as a return duct elbow, this structure technology is good, but because the pipe protruding nut body, a larger radial dimension. Spiral trough, which is milled in the nut outer helical grooves, through holes drilled at both ends of the groove and the thread roller tangent to form a return channel, this structure is smaller than the radial dimension of the cannula structure, but Manufacturing is more complex. Ball outer loop outer loop structure and manufacturing process is simple, widely used. Ball | Chuxiong Ball | Shandong Fu Jun is provided by Mechanical Technology Co., Ltd. Shandong Fu Jun.
