Worm Gear electrical ball screw jack, anti-Rotation and higher pitches available
Translating(traveling screw) and rotating (traveling nut) configurations
Move loads and apply force more efficiently than additional machine screw actuators
No worm screw jack self-locking! Because of having less friction, a holding brake is essential: a engine brake or a springtime pressure brake is necessary.
These worm equipment screw jacks are extremely precision and reliability, it can meet all of the necessary protection, cost-efficiency, and strength mandates of the application. High strength bronze worm gear is used, the payloads from 0.5T to 100T . A complete of 11 sizes can be found, each in a journeying nut version and a simple version.
The screw jacks can be used separately or in organizations linked with drive shafts, joints, couplings, bevel gearboxes and additional mechanical components. In addition they could be powered by different motors: electric, with either AC electric motor or DC motor along with hydraulic or pneumatic motors. Each one of these motion control items can be built-in many type jacking program arrangements or configurations.
Ball screw jacks are common where higher speeds and duty cycles are needed. Most screw jacks make use of trapezoidal screws Tr, because they’re basic, robust and inexpensive. The proportion of screw jacks that use ball screws is nevertheless constantly increasing. The reasons for this are primarily their pitch accuracy, their high efficiency (much less power consumption and less heat generation) and the bigger pitches available, which permit higher stroke speeds.
A screw jack can truly add a machine cut lifting nut. For this model screw jack, just the bronze nut move combined with the screw shaft. The lifting screw will not slide. It is certainly like the linear actuator functioning theory which converts rotational movement into linear motion. Out of this point to understand, a power linear actuator is a motorized screw jack.
The screw thread of screw jack could be acme screw and ball screw. So there are few variations of the screw jack. Commonly, machine screw jack and ball screw jack can be found in your engineer project. Weighed against acme screw, the ball screw is better as there are ball bearings between the nut and screw. The anti-friction ball bearing can increase the ball screw efficiency.
