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 efficiently than various other machine screw actuators
No self-locking! Because of the lack of friction, a holding brake is necessary: a engine 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 strength mandates of your application. High strength bronze worm gear can be used, the payloads from 0.5T to 100T . A complete of 11 sizes are available, each in a journeying nut version and a basic version.
The screw jacks can be utilized Worm Gear Jack separately or in groupings connected with drive shafts, joints, couplings, bevel gearboxes and various other mechanical components. They also could be driven by different motors: electric, with either AC engine or DC motor in addition to hydraulic or pneumatic motors. Each one of these motion control items could be built-in many type jacking system 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’re basic, robust and inexpensive. The proportion of screw jacks that use ball screws is however constantly increasing. The reasons for this are mainly their pitch precision, their high efficiency (much less power consumption and much less heat generation) and the higher pitches available, 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 movement into linear motion. Out of this stage to understand, a power linear actuator is usually a motorized screw jack.
The screw thread of screw jack could 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 project. Compared with acme screw, the ball screw is better as there are ball bearings between the nut and screw. The anti-friction ball bearing can boost the ball screw efficiency.
