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 self-locking! Due to having less friction, a holding brake is necessary: a electric motor brake or a spring pressure brake is necessary.
These worm gear screw jacks are very precision and reliability, it could meet all the necessary safety, cost-efficiency, and durability mandates of your 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 utilized separately or in organizations connected with drive shafts, joints, couplings, bevel gearboxes and other mechanical components. In addition they can be driven by different motors: electric, with either AC electric motor 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 use trapezoidal screws Tr, because they are simple, 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 (less power Worm Gear Jack 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. Because of this model screw jack, just the bronze nut move along with the screw shaft. The lifting screw does not slide. It is definitely similar to the linear actuator operating basic principle which converts rotational motion into linear motion. From this stage to understand, an electric linear actuator is 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. 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 boost the ball screw efficiency.
