Drive to do a linear movement of the spiral, look at the net efficiency of the ball screw rod is relatively high, if the ball screw to make the counter revolution, is the nut with a one-way bearing vertical fixation, screw up and down reciprocating motion, so that you can do, if possible, wire rod length 40CM screw diameter, 8MM, vertical pressure 80N of the screw, choose the lead big nut can make the speed to 700 RPM in the under pressure?
This usage is really special. I have 3 years to lead screw sales have not encountered.
But the rod itself can not be subjected to radial force, otherwise the life will be greatly reduced.Specific circumstances of specific analysis.
Many manufacturers are now producing this kind of machine, that is, the rotor and the screw nut are made together
