When a worm gear screw jack is driven by electrical motor, the rotation of the worm shaft causes the worm gear to rotate. For translating screw jacks the worm gear is threaded to accommodate the lead screw thread. As the worm gear turns, the friction forces on the screw thread act to turn the screw also. The greater the load on the screw jack unit, the greater the tendency of the screw to turn. It is obvious that if the screw turns with the worm gear, it will not raise the load. In those cases where a single jack is used, and where the load cannot be restrained from turning, it is necessary to screw jack with an anti-rotation mechanism, called keyed screw jack.
working of electrical screw jack actuator,motor driven jack screw,electric worm gear screw jack lift allowable voltage,phases and hertz includes 380V-3 Phases-50HZ, 220V-3 Phases-50HZ, 400V-3 Phases-50HZ, 415V-3 Phases-50HZ, 440V-3 Phases-50HZ, 480V-3 Phases-50HZ, 220V-3 Phases-60HZ, 240V-3 Phases-60HZ, 480V-3 Phases-60HZ, 110V-Single Phase-60HZ, 120V-Single Phase-60HZ, 220V-Single Phase-50HZ, 230V-Single Phase-50HZ, 240V-Single Phase-50HZ. For special application, for example solar tracker industry, most of engineers or designers prefer to use 24V, 36V, 48V DC motor with gear reducer.
