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 efficiently than other machine screw actuators
No self-locking! Because of the lack of friction, a keeping brake is necessary: a engine brake or a springtime pressure brake is required.
These worm gear screw jacks are very precision and reliability, it could meet all of the necessary basic safety, cost-efficiency, and strength mandates of the application. High power bronze worm gear is used, the payloads from 0.5T to 100T . A complete of 11 sizes are available, each in a Worm Gear Jack touring nut version and a basic version.

The screw jacks can be used separately or in groupings connected with drive shafts, joints, couplings, bevel gearboxes and additional mechanical components. In addition they can be driven by different motors: electric, with either AC electric motor or DC motor and also hydraulic or pneumatic motors. Each one of these motion control products can be built-in many type jacking system 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 are basic, robust and inexpensive. The proportion of screw jacks that use ball screws is however constantly increasing. The reason why for this are primarily their pitch precision, their high efficiency (less power consumption and much less heat era) and the higher pitches obtainable, which permit higher stroke speeds.

A screw jack can truly 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 does not slide. It is usually similar to the linear actuator operating basic principle 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 are there few variations of the screw jack. Commonly, machine screw jack and ball screw jack are available in your 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.
