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 other machine screw actuators
No self-locking! Due to having less friction, a holding brake is essential: a motor brake or a springtime pressure brake is necessary.
These worm gear screw jacks are extremely precision and reliability, it can meet all the necessary security, cost-efficiency, and sturdiness mandates of the 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 used separately or in organizations linked with drive shafts, joints, couplings, bevel gearboxes and additional mechanical components. They also could be Worm Gear Jack driven by different motors: electrical, with either AC motor or DC motor as well as hydraulic or pneumatic motors. All these motion control products could be built-in many type jacking system 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 simple, 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 less heat generation) and the higher 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 usually like the linear actuator operating principle which converts rotational motion into linear motion. From this point to understand, a power linear actuator is certainly 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 can be found in your engineer project. Compared with acme screw, the ball screw is better as there are ball bearings between your nut and screw. The anti-friction ball bearing can boost the ball screw efficiency.
