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 having less friction, a keeping brake is essential: a engine brake or a springtime pressure brake is necessary.
These worm gear screw jacks are extremely precision and reliability, it could meet all of the necessary protection, cost-efficiency, and toughness mandates of the application. High strength bronze worm gear can be used, the payloads from 0.5T to 100T . A total of 11 sizes are available, each in a vacationing nut version and a simple version.
The screw jacks can be used separately or in groupings linked with drive shafts, joints, couplings, bevel gearboxes and additional mechanical components. In addition they could be driven by different motors: electric, with either AC motor or DC motor in addition to hydraulic or pneumatic motors. All these motion control products can 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’re simple, robust and inexpensive. The proportion of screw jacks that make use of ball screws is nevertheless constantly increasing. The reason why for this are mainly their pitch accuracy, their high efficiency (less power consumption and much less heat era) and the bigger pitches available, which permit higher stroke speeds.
A screw jack can truly add a machine cut lifting nut. For this model screw jack, only the bronze nut move together with the screw shaft. The lifting screw does not slide. It is similar to the linear actuator functioning theory which converts rotational motion into linear motion. Out of this point 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 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 definitely more Worm Gear Jack efficient as there are ball bearings between the nut and screw. The anti-friction ball bearing can raise the ball screw efficiency.
