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 the lack of friction, a holding brake is essential: a motor brake or a spring pressure brake is required.
These worm gear screw jacks are very precision and reliability, it can meet all of the necessary safety, cost-efficiency, and strength mandates of the application. High strength 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 used separately or in groupings connected with drive shafts, joints, couplings, bevel gearboxes and additional mechanical components. They also could be powered by different motors: Worm Gear Jack electrical, with either AC motor or DC motor as well as hydraulic or pneumatic motors. All these motion control products can 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 (less power consumption and less heat era) and the bigger 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 usually like the linear actuator functioning theory which converts rotational motion into linear motion. Out of this point to understand, an electric 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 variants of the screw jack. Commonly, machine screw jack and ball screw jack can be found in your engineer task. Weighed against acme screw, the ball screw is definitely more efficient as there are ball bearings between the nut and screw. The anti-friction ball bearing can boost the ball screw efficiency.
