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 additional machine screw actuators
No self-locking! Because of the lack of friction, a keeping brake is necessary: a engine brake or a spring pressure brake is necessary.
These worm equipment screw jacks are extremely precision and reliability, it could meet all of the necessary basic safety, cost-efficiency, and strength mandates of your 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 traveling nut version and a simple version.
The screw jacks can be used separately or in groups linked with drive shafts, joints, couplings, bevel gearboxes and various other mechanical components. In addition they could be driven by different motors: electrical, with either AC motor or DC motor along with hydraulic or pneumatic motors. Each one of these motion control items could be built-in many type jacking system 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’re simple, robust and inexpensive. The proportion of screw jacks that use ball screws is however constantly increasing. The reason why for this are mainly their pitch accuracy, their high efficiency (much 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. Because of this model screw jack, only the bronze nut move together with the screw shaft. The lifting screw does not slide. It is usually like the linear actuator operating principle which converts rotational motion into linear motion. Out of this point 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 variations of the screw jack. Commonly, machine screw jack and ball screw jack can be found in your engineer project. worm screw jack Compared with acme screw, the ball screw is definitely better as there are ball bearings between your nut and screw. The anti-friction ball bearing can boost the ball screw efficiency.
