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 spring pressure brake is required.
These worm gear screw jacks are extremely precision and reliability, it can meet all of the necessary protection, Worm Gear Jack cost-efficiency, and toughness mandates of the application. High power bronze worm gear can be used, the payloads from 0.5T to 100T . A total of 11 sizes can be found, 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 other 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. Each one of 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 precision, 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 combined with the screw shaft. The lifting screw will not slide. It can be like the linear actuator operating 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 there are 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 more efficient as there are ball bearings between the nut and screw. The anti-friction ball bearing can boost the ball screw efficiency.
