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 various other machine screw actuators
No self-locking! Due to the lack of friction, a holding brake is essential: a electric motor brake or a spring pressure brake is necessary.
These worm gear screw jacks are extremely precision and reliability, it could meet all the necessary security, cost-efficiency, and sturdiness 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 basic version.
The screw jacks can be used separately or in worm screw jack groupings linked with drive shafts, joints, couplings, bevel gearboxes and additional mechanical components. In addition they can be driven by different motors: electrical, with either AC motor 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 common 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 nevertheless constantly increasing. The reason why for this are primarily their pitch accuracy, their high efficiency (less power consumption and less heat era) and the higher 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 together with the screw shaft. The lifting screw will not slide. It is definitely like the linear actuator working principle which converts rotational motion into linear motion. From this stage 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 are there few variants of the screw jack. Commonly, machine screw jack and ball screw jack are available in your engineer project. Weighed against acme screw, the ball screw is usually more efficient as there are ball bearings between your nut and screw. The anti-friction ball bearing can boost the ball screw efficiency.
