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 efficiently than other machine screw actuators
No self-locking! Due to having less friction, a keeping brake is necessary: a electric 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 Worm Gear Jack necessary security, cost-efficiency, and toughness mandates of the application. High strength bronze worm gear is used, the payloads from 0.5T to 100T . A complete of 11 sizes are available, each in a traveling nut version and a simple version.
The screw jacks can be used separately or in groupings connected with drive shafts, joints, couplings, bevel gearboxes and additional mechanical components. They also could be powered by different motors: electrical, 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 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’re simple, robust and inexpensive. The proportion of screw jacks that use ball screws is nevertheless constantly increasing. The reason why for this are primarily their pitch precision, their high efficiency (much less power consumption and less heat era) and the bigger pitches offered, which permit higher stroke speeds.
A screw jack can 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 basic principle which converts rotational movement into linear motion. Out of this point to understand, an electric linear actuator can be a motorized screw jack.
The screw thread of screw jack can 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. Compared with acme screw, the ball screw is better as there are ball bearings between the nut and screw. The anti-friction ball bearing can increase the ball screw efficiency.
