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! Due to having less friction, a keeping brake is essential: a motor brake or a springtime pressure brake is required.
These worm equipment screw jacks are extremely precision and reliability, it can meet all of the necessary basic safety, cost-efficiency, and sturdiness mandates of the Worm Gear Jack application. High power bronze worm gear is used, the payloads from 0.5T to 100T . A total of 11 sizes can be found, each in a traveling 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 various other mechanical components. They also can be driven by different motors: electric, with either AC motor or DC motor in addition to hydraulic or pneumatic motors. All these motion control items could 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 make use of trapezoidal screws Tr, because they’re basic, robust and inexpensive. The proportion of screw jacks that make use of ball screws is however constantly increasing. The reasons for this are mainly their pitch precision, their high efficiency (less power consumption and much 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, only the bronze nut move along with the screw shaft. The lifting screw will not slide. It can be similar to the linear actuator functioning basic principle which converts rotational motion into linear motion. From this stage to understand, a power linear actuator can be 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 task. Weighed against acme screw, the ball screw can be better as there are ball bearings between your nut and screw. The anti-friction ball bearing can increase the ball screw efficiency.
