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! Because of the lack of friction, a holding brake is necessary: a motor brake or a spring pressure brake is required.
These worm equipment screw jacks are very precision and reliability, it could meet all of the necessary basic safety, cost-efficiency, and durability mandates of your 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 vacationing nut version and a basic version.
The screw jacks can be used separately or in groupings connected with drive shafts, joints, couplings, bevel gearboxes and various other mechanical components. In addition they can be powered by different motors: electrical, with either AC motor or DC motor along with Worm Gear Jack hydraulic or pneumatic motors. Each one of 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 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 however constantly increasing. The reason why for this are primarily their pitch accuracy, their high efficiency (much less power consumption and much less heat generation) and the bigger pitches available, which permit higher stroke speeds.
A screw jack can truly add a machine cut lifting nut. Because of this model screw jack, just the bronze nut move combined with the screw shaft. The lifting screw will not slide. It is definitely like the linear actuator functioning principle which converts rotational movement into linear motion. From this stage to understand, an electric linear actuator is a motorized screw jack.
The screw thread of screw jack could 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 task. Weighed against acme screw, the ball screw is definitely better as there are ball bearings between your nut and screw. The anti-friction ball bearing can increase the ball screw efficiency.
