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 self-locking! Due to the lack of friction, a holding brake is necessary: a motor brake or a spring 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 strength mandates of your application. High power bronze worm gear is used, the payloads from 0.5T to 100T . A total of 11 sizes are available, each in a touring 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 other mechanical components. In addition they could be driven by different motors: electrical, with either AC motor or DC motor in addition to hydraulic or pneumatic motors. Each one of 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 make use of trapezoidal screws Tr, because they are basic, robust and inexpensive. The proportion of screw jacks that make use of ball screws is nevertheless constantly increasing. The reason why for this are mainly their pitch precision, their high efficiency (less power consumption and much less heat generation) and the higher 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 combined with the screw shaft. The lifting screw does not slide. It is usually similar to the linear actuator operating theory which converts rotational movement into linear motion. Out of this stage to understand, a power linear actuator is certainly 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. Compared with acme screw, the ball screw is definitely more efficient as there are ball bearings between the nut and screw. The Worm Gear Jack anti-friction ball bearing can raise the ball screw efficiency.
