worm gear jack

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 effectively than various other machine screw actuators
No self-locking! Due to the lack of friction, a keeping brake is essential: a electric motor brake or a spring pressure brake is necessary.
These worm equipment screw jacks are very precision and reliability, it could meet all of the necessary basic safety, cost-efficiency, and sturdiness mandates of the application. High strength 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 basic version.

The screw jacks can be used separately or in groupings linked with drive shafts, joints, couplings, bevel gearboxes and other mechanical components. In addition they can be powered by different motors: electrical, with either AC engine or DC motor along with hydraulic or pneumatic motors. Each one of 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 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 Worm Gear Jack increasing. The reason why for this are mainly their pitch precision, 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, only the bronze nut move along with the screw shaft. The lifting screw does not slide. It is like the linear actuator working basic principle which converts rotational motion into linear motion. From this point to understand, a power linear actuator is definitely 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 task. Compared with acme screw, the ball screw is usually better as there are ball bearings between your nut and screw. The anti-friction ball bearing can raise the ball screw efficiency.
