worm gear jack

Worm Gear electrical ball screw jack, anti-Rotation and Worm Gear Jack 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 engine brake or a springtime pressure brake is necessary.
These worm equipment screw jacks are very precision and reliability, it can meet all of the necessary protection, cost-efficiency, and sturdiness mandates of your 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 groupings connected with drive shafts, joints, couplings, bevel gearboxes and various other mechanical components. In addition they could be driven by different motors: electric, with either AC engine or DC motor and also hydraulic or pneumatic motors. Each one of these motion control items 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 use trapezoidal screws Tr, because they’re basic, 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 precision, their high efficiency (less power consumption and less heat generation) and the bigger pitches offered, which permit higher stroke speeds.

A screw jack can add a machine cut lifting nut. For this model screw jack, just the bronze nut move combined with the screw shaft. The lifting screw does not slide. It is usually like the linear actuator working theory which converts rotational movement into linear motion. From this stage to understand, a power linear actuator is certainly a motorized screw jack.

The screw thread of screw jack could 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. 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.
