DKFZD COMPACT&HIGH SPEED BALL SCREW
Please pay attention to following points to use ball screw:
• Nut should work in the available travel. If ii is necessary, limit unit must be installed on the two ends of travel in order to avoid that the ball fall when nut goes over-travel. If the nut deviates screw or ball falls, please have a contact with us .
• Because of high transmission efficiency, ball screw could not keep selfhold. When used to drive in vertical direction reverse transmission as a result of dead weight after the motion stops or motor is out of electricity should be prevented. There are many mechanisms to prevent reverse transmission such as worm wheel and arbor, Hydraulic braker, electromagnetic braker and overrunning coupler as well. If overrunning coupler is to need, we can design and manufacture for customer .
