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 effectively than additional machine screw actuators
No self-locking! Because of having less friction, a holding brake is necessary: a engine brake or a springtime pressure brake is required.
These worm gear screw jacks are very precision and reliability, it could meet all the necessary basic safety, cost-efficiency, and durability mandates of your application. High power worm screw jack bronze worm gear is used, the payloads from 0.5T to 100T . A total of 11 sizes are available, each in a journeying nut version and a basic version.
The screw jacks can be used separately or in organizations connected with drive shafts, joints, couplings, bevel gearboxes and additional mechanical components. In addition they could be driven by different motors: electric, with either AC electric motor or DC motor in addition to 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 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 era) 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 will not slide. It is definitely similar to the linear actuator functioning basic principle which converts rotational motion into linear motion. Out of this stage to understand, an electric linear actuator is usually 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 project. Compared with acme screw, the ball screw is certainly more efficient as there are ball bearings between the nut and screw. The anti-friction ball bearing can boost the ball screw efficiency.
