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 effectively than additional machine screw actuators
No self-locking! Due to having less friction, a keeping brake is essential: a engine brake or a springtime pressure brake is necessary.
These worm gear screw jacks are very precision and reliability, it can meet all the necessary security, cost-efficiency, and sturdiness mandates of the 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 vacationing nut version and a simple version.

The screw jacks can be utilized separately or in groups connected with drive shafts, joints, couplings, bevel gearboxes and other mechanical components. They also could be powered by different motors: electric, with either AC motor or DC motor as well as hydraulic or pneumatic motors. All these motion control items can be built-in many type jacking program worm screw jack 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’re basic, robust and inexpensive. The proportion of screw jacks that make use of ball screws is however constantly increasing. The reasons for this are mainly their pitch accuracy, their high efficiency (much less power consumption and much less heat generation) and the higher 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 combined with the screw shaft. The lifting screw will not slide. It is definitely like the linear actuator operating theory which converts rotational motion into linear motion. Out of this stage to understand, a power linear actuator is 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 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 anti-friction ball bearing can raise the ball screw efficiency.
