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! Because of the lack of 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 could meet all of the necessary safety, cost-efficiency, and durability mandates of your application. High power bronze worm gear is used, the payloads from 0.5T to 100T . A complete of 11 sizes can be found, each in a traveling nut version and a basic version.
The screw jacks can be utilized separately or in groups linked with drive shafts, joints, couplings, bevel gearboxes and various other mechanical components. In addition they can be powered by different motors: electric, with either AC motor or DC motor along with hydraulic or pneumatic motors. Each one of these motion control products can be built in many type jacking system arrangements or configurations.
Ball screw jacks are Worm Gear Jack normal where higher speeds and duty cycles are needed. Most screw jacks make use of trapezoidal screws Tr, because they are basic, robust and inexpensive. The proportion of screw jacks that use ball screws is nevertheless constantly increasing. The reasons for this are primarily their pitch precision, their high efficiency (less power consumption and less heat generation) and the bigger pitches obtainable, which permit higher stroke speeds.
A screw jack can truly add a machine cut lifting nut. Because of this model screw jack, just the bronze nut move along with the screw shaft. The lifting screw will not slide. It is definitely similar to the linear actuator operating theory which converts rotational movement into linear motion. From 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 there are few variants of the screw jack. Commonly, machine screw jack and ball screw jack can be found in your engineer project. Compared with 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 increase the ball screw efficiency.
