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 various other machine screw actuators
No self-locking! Due to the lack of friction, a keeping brake is essential: a engine brake or a springtime pressure brake is required.
These worm equipment screw jacks are very precision and reliability, it could meet all the necessary security, 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 journeying nut version and a simple 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 can be driven by different motors: electric, with either AC engine or DC motor in addition to hydraulic or pneumatic motors. Each one of these motion control items could be built-in many type jacking Worm Gear Jack 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 however 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. Because of 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 are there 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 anti-friction ball bearing can raise the ball screw efficiency.
