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 additional machine screw actuators
No worm screw jack self-locking! Due to the lack of friction, a holding brake is necessary: a engine brake or a spring pressure brake is required.
These worm gear screw jacks are extremely precision and reliability, it can meet all the necessary security, cost-efficiency, and durability mandates of the application. High power 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 simple version.
The screw jacks can be used separately or in organizations connected with drive shafts, joints, couplings, bevel gearboxes and other mechanical components. They also could be powered by different motors: electric, with either AC engine or DC motor as well as hydraulic or pneumatic motors. All these motion control products could be built-in many type jacking program arrangements or configurations.
Ball screw jacks are normal 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 reason why for this are primarily their pitch accuracy, their high efficiency (much 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. For this model screw jack, just the bronze nut move along with the screw shaft. The lifting screw does not slide. It is similar to the linear actuator operating basic principle which converts rotational motion into linear motion. From this point to understand, a power linear actuator is definitely a motorized screw jack.
The screw thread of screw jack can be acme screw and ball screw. So are there few variations of the screw jack. Commonly, machine screw jack and ball screw jack can be found in your engineer task. Compared with 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.
