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! Because of 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 Worm Gear Jack necessary basic safety, cost-efficiency, and durability 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 groups linked with drive shafts, joints, couplings, bevel gearboxes and various other mechanical components. In addition they can be driven by different motors: electrical, with either AC electric motor or DC motor and also 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 are basic, robust and inexpensive. The proportion of screw jacks that make use of ball screws is however constantly increasing. The reasons for this are mainly their pitch accuracy, their high efficiency (less power consumption and much less heat generation) and the bigger pitches available, 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 combined with the screw shaft. The lifting screw will not slide. It is usually similar to the linear actuator functioning theory which converts rotational motion into linear motion. Out of this point 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 there are few variations of the screw jack. Commonly, machine screw jack and ball screw jack can be found in your engineer task. Weighed against acme screw, the ball screw is more efficient as there are ball bearings between your nut and screw. The anti-friction ball bearing can raise the ball screw efficiency.
