worm screw jack

Worm Gear electric 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 other machine screw actuators
No self-locking! Because of the lack of friction, a holding brake is necessary: a engine brake or a spring pressure brake is required.
These worm equipment screw jacks are extremely precision and reliability, it can meet all the worm screw jack necessary protection, cost-efficiency, and durability mandates of the application. High strength bronze worm gear can be used, the payloads from 0.5T to 100T . A total of 11 sizes can be found, each in a traveling nut version and a basic version.

The screw jacks can be utilized separately or in organizations linked with drive shafts, joints, couplings, bevel gearboxes and additional mechanical components. They also could be powered by different motors: electrical, with either AC electric motor or DC motor as well as 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 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 make use of ball screws is nevertheless constantly increasing. The reasons for this are primarily their pitch accuracy, their high efficiency (much less power consumption and much 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, just the bronze nut move combined with the screw shaft. The lifting screw does not slide. It is certainly like the linear actuator operating basic principle which converts rotational movement into linear motion. From this stage to understand, a power linear actuator is definitely 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 are available in your engineer task. Weighed against acme screw, the ball screw can be more efficient as there are ball bearings between the nut and screw. The anti-friction ball bearing can raise the ball screw efficiency.
