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 various other machine screw actuators
No self-locking! Due to having less friction, a keeping brake is essential: a engine brake or a springtime pressure brake is required.
These worm equipment screw jacks are extremely precision and reliability, it can meet all the Worm Gear Jack necessary protection, 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 are available, each in a touring nut version and a simple version.
The screw jacks can be utilized separately or in groups connected with drive shafts, joints, couplings, bevel gearboxes and other mechanical components. They also could be powered by different motors: electrical, with either AC motor or DC motor and also hydraulic or pneumatic motors. Each one of these motion control items 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 make use of trapezoidal screws Tr, because they are simple, 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 (much less power consumption and much less heat era) and the higher pitches obtainable, 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 along with the screw shaft. The lifting screw will not slide. It is definitely like the linear actuator functioning theory which converts rotational motion into linear motion. From 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 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 raise the ball screw efficiency.
