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 efficiently than additional machine screw actuators
No self-locking! Due to having less friction, a keeping brake is necessary: a motor brake or a springtime pressure brake is necessary.
These worm gear screw jacks are extremely precision and reliability, it could meet all the necessary basic safety, cost-efficiency, and sturdiness 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 touring nut version and a basic version.
The screw jacks can be utilized separately or in groups linked with drive shafts, joints, couplings, bevel gearboxes and additional mechanical components. In addition they could be powered by different motors: electric, with either AC motor or DC motor along with 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 are simple, robust and inexpensive. The proportion of screw jacks that make use of ball screws is nevertheless constantly increasing. The reasons for this are primarily their pitch accuracy, their high efficiency (less power consumption and less heat era) and the higher pitches offered, which permit higher stroke speeds.
A screw jack can 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 will not slide. It is usually like the linear actuator functioning basic principle which converts rotational motion into linear motion. From this stage to understand, a power linear actuator is 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 are available in your worm screw jack engineer project. Weighed against acme screw, the ball screw is certainly better as there are ball bearings between your nut and screw. The anti-friction ball bearing can increase the ball screw efficiency.
