CSK precision ball screw features: a uniform and smooth torque communicate because the rolling ball screw actuator contacting the starting small friction, to enter sensitive and precise movements, so small movements can be precisely controlled. Select the appropriate preload pressure way to get one of the pre-high rigidity ball screw is to use two nuts, and install the gasket between them. In this case, by selecting the gasket can be properly preload and high rigidity. Another way is to use only a single nut, ball mill, can be achieved without clearance (light preload) state. Outer circulation ball screw nut ball circulation mode Press Back when the main cover type, tube and spiral trough. Unlike linear guides, ball screws buy its common outer loop mode (a) cap formula; (b) intubation; (c) screw cap type trough is processing a longitudinal hole in the nut, as ball return passage, opened a ball return cover nut on both ends of the 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, Dehong ball screw, a larger radial dimension. Spiral trough, the ball screw shaft, 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 than the diameter of the cannula structure to the small size, but the manufacturing more complicated. Ball outer loop outer loop structure and manufacturing process is simple, widely used. Dehong Ball | Shandong Fu Jun | Ball sales by Shandong Fu Jun Mechanical Technology Limited.
