Worm Gear electric ball screw jack, worm 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 the lack of friction, a keeping brake is necessary: a electric motor brake or a springtime pressure brake is necessary.
These worm gear screw jacks are extremely precision and reliability, it can meet all of the necessary safety, cost-efficiency, and sturdiness mandates of your application. High strength bronze worm gear can be used, the payloads from 0.5T to 100T . A total of 11 sizes are available, each in a traveling nut version and a basic version.
The screw jacks can be utilized separately or in organizations connected with drive shafts, joints, couplings, bevel gearboxes and various other mechanical components. In addition they 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 products 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 use trapezoidal screws Tr, because they are basic, robust and inexpensive. The proportion of screw jacks that use ball screws is however constantly increasing. The reason why for this are primarily their pitch accuracy, their high efficiency (less power consumption and much less heat generation) and the bigger pitches offered, which permit higher stroke speeds.
A screw jack can add a machine cut lifting nut. For this model screw jack, only the bronze nut move combined with the screw shaft. The lifting screw will not slide. It is certainly similar to the linear actuator functioning theory which converts rotational movement into linear motion. From this point to understand, an electric linear actuator is usually 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 task. Compared with acme screw, the ball screw is more efficient as there are ball bearings between your nut and screw. The anti-friction ball bearing can boost the ball screw efficiency.
