worm screw jack

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 holding brake is essential: a motor brake or a spring pressure brake is required.
These worm gear screw jacks are extremely precision and reliability, it could meet all the necessary security, cost-efficiency, and sturdiness mandates of the 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 utilized separately or in organizations connected with drive shafts, joints, couplings, bevel gearboxes and various other mechanical components. They also can be driven by different motors: electrical, with either AC electric motor or DC motor in addition to hydraulic or pneumatic motors. Each one of these motion control items could 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 use trapezoidal screws Tr, because they are simple, robust and inexpensive. The proportion of screw jacks that make use of ball screws is worm screw jack nevertheless constantly increasing. The reasons for this are mainly their pitch accuracy, their high efficiency (less power consumption and much less heat generation) and the higher pitches obtainable, 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 combined with the screw shaft. The lifting screw will not slide. It is definitely like the linear actuator operating basic principle which converts rotational movement into linear motion. From this stage to understand, an electric linear actuator is a motorized screw jack.

The screw thread of screw jack could 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 engineer project. 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 boost the ball screw efficiency.
