Ball Features 1, high-speed feeding and micro-feed may ball screw ball movement, so very small starting torque, it does not appear sliding movement as creeping phenomenon, to ensure accurate micro feed. 2, the axial stiffness of ball screw can be added to the pre-press, since the pre-axial clearance can achieve negative pressure, and then get the higher rigidity (ball screw ball through to add to the pressure, in practical use mechanical devices, because the ball repulsion can enhance the rigidity Ministry of wire mother). 3, can not be self-locking, reversible outer loop with a drive by ball screw nut ball circulation mode to return when the main cover type, tube and spiral trough. Unlike buying a ball screw 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, as the ball the return channel, the cover is opened at both ends of the ball nut backhaul mouth ball screws, 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 ball screw nut in vitro Buying radially larger size. Supply Ball screw trough, which is milled in the nut outer spiral grooves through holes drilled at both ends of the groove and the thread roller tangent to form a return channel, this structure than the radial tube structure small size, but the manufacturing more complicated. Ball outer loop outer loop structure and manufacturing process is simple, widely used. Ball | Shandong Fu Jun (certified) | Nyingchi ball screw is provided by Mechanical Technology Co., Ltd.
