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 various other machine screw actuators
No self-locking! Because of the lack of friction, a keeping brake is essential: a engine brake or a springtime pressure brake is necessary.
These worm gear screw jacks are extremely precision and reliability, it could meet all the necessary security, cost-efficiency, and sturdiness 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 touring nut version and a basic version.
The screw jacks can be used separately or in organizations connected with drive shafts, joints, couplings, bevel gearboxes and additional mechanical components. They also could be driven by different motors: electric, with either AC electric motor or DC motor along with hydraulic or pneumatic motors. All these motion control items could be built in many type jacking program arrangements or configurations.
Ball screw jacks are normal where higher speeds and duty cycles are needed. Most screw jacks use trapezoidal screws Tr, because they are simple, robust and inexpensive. The worm screw jack proportion of screw jacks that use ball screws is nevertheless constantly increasing. The reason why for this are primarily their pitch precision, 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, just the bronze nut move together with the screw shaft. The lifting screw will not slide. It is usually similar to the linear actuator operating principle which converts rotational movement into linear motion. From this stage to understand, an electric linear actuator is usually a motorized screw jack.
The screw thread of screw jack can be acme screw and ball screw. So there are few variants of the screw jack. Commonly, machine screw jack and ball screw jack are available in your engineer task. Compared with acme screw, the ball screw is certainly more efficient as there are ball bearings between your nut and screw. The anti-friction ball bearing can raise the ball screw efficiency.
