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 effectively than other machine screw actuators
No self-locking! Due to having less friction, a keeping brake is essential: a electric motor brake or a springtime pressure brake is required.
These worm equipment screw jacks are very precision and reliability, it can meet all of the necessary basic safety, cost-efficiency, and durability mandates of the application. High power bronze worm gear is 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 used separately or in organizations linked with drive shafts, joints, couplings, bevel gearboxes and additional mechanical components. In addition they can be powered by different motors: electrical, with either AC electric motor or DC motor and also hydraulic or pneumatic motors. All these motion control products can 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 use trapezoidal screws Tr, because they are simple, robust and inexpensive. The proportion of screw jacks that make use of ball screws is however constantly increasing. The reason why for this are primarily their pitch precision, their high efficiency (less power Worm Gear Jack 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 along with the screw shaft. The lifting screw will not slide. It can be similar to the linear actuator functioning basic principle which converts rotational motion into linear motion. From this stage to understand, a power linear actuator can be a motorized screw jack.
The screw thread of screw jack can be acme screw and ball screw. So are there few variants 
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 is definitely more efficient as there are ball bearings between your nut and screw. The anti-friction ball bearing can increase the ball screw efficiency.
