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 additional machine screw actuators
No self-locking! Because of having less friction, a worm screw jack keeping brake is essential: a electric motor brake or a springtime pressure brake is required.
These worm equipment screw jacks are extremely precision and reliability, it could meet all of the necessary basic safety, cost-efficiency, and sturdiness mandates of the 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 journeying nut version and a basic version.
The screw jacks can be utilized separately or in groupings linked with drive shafts, joints, couplings, bevel gearboxes and various other mechanical components. In addition they could be driven by different motors: electric, with either AC motor or DC motor and also hydraulic or pneumatic motors. All these motion control items could be built-in many type jacking program 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 are basic, robust and inexpensive. The proportion of screw jacks that make use of ball screws is nevertheless constantly increasing. The reasons for this are mainly their pitch precision, their high efficiency (much less power consumption and less heat era) and the bigger pitches obtainable, 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 does not slide. It can be like the linear actuator working theory which converts rotational motion into linear motion. Out of this stage to understand, an electric linear actuator is usually 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 can be found in your engineer task. Weighed against acme screw, the ball screw 
can be more efficient as there are ball bearings between your nut and screw. The anti-friction ball bearing can raise the ball screw efficiency.
