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 effectively than other machine screw actuators
No self-locking! Due to having less friction, a holding brake is essential: a engine brake or a spring pressure brake is required.
These worm gear screw jacks are very precision and reliability, it can meet all the necessary basic safety, cost-efficiency, and strength mandates of the application. High power bronze worm gear can be used, the payloads from 0.5T to 100T . A complete of 11 sizes are available, each in a traveling nut version and a basic version.
The screw jacks can be used separately or in groupings connected with drive shafts, joints, couplings, bevel gearboxes and additional mechanical components. They also can be powered by different motors: electric, with either AC motor or DC motor in addition to hydraulic or pneumatic motors. Each one of these motion control worm screw jack products can be built-in many type jacking system arrangements or configurations.
Ball screw jacks are normal where higher speeds and duty cycles are needed. Most screw jacks make use of trapezoidal screws Tr, because they are simple, robust and inexpensive. The proportion of screw jacks that use ball screws is nevertheless constantly increasing. The reason why for this are mainly their pitch precision, their high efficiency (much less power consumption and less heat era) and the bigger pitches offered, which permit higher stroke speeds.
A screw jack can truly add a machine cut lifting nut. For this model screw jack, only the bronze nut move along with the screw shaft. The lifting screw does not slide. It is certainly like the linear actuator operating theory which converts rotational motion into linear motion. From this point to understand, a power linear actuator is definitely a motorized screw jack.
The screw thread of screw jack can be acme screw and ball screw. So are there few variants of the screw jack. Commonly, machine screw jack and ball screw jack can be found in your engineer task. Weighed against acme screw, the ball screw is usually better as there are ball bearings between the nut and screw. The anti-friction ball bearing can raise the ball screw efficiency.
