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! Due to the lack of friction, a holding 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 the necessary basic Worm Gear Jack safety, cost-efficiency, and strength mandates of your application. High strength bronze worm gear can be used, the payloads from 0.5T to 100T . A total of 11 sizes can be found, each in a journeying nut version and a basic version.
The screw jacks can be utilized separately or in organizations linked with drive shafts, joints, couplings, bevel gearboxes and other mechanical components. In addition they can be driven by different motors: electric, with either AC motor or DC motor along with hydraulic or pneumatic motors. All these motion control products could be built-in many type jacking system arrangements or configurations.
Ball screw jacks are normal 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 however constantly increasing. The reason why for this are primarily their pitch precision, their high efficiency (much less power consumption and much 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, just the bronze nut move combined with the screw shaft. The lifting screw does 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 is certainly a motorized screw jack.
The screw thread of screw jack could 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 can be more efficient as there are ball bearings between your nut and screw. The anti-friction ball bearing can boost the ball screw efficiency.
