worm gear jack

Worm Gear electrical ball screw jack, Worm Gear Jack anti-Rotation and higher pitches available
Translating(traveling screw) and rotating (traveling nut) configurations
Move loads and apply force more effectively than other machine screw actuators
No self-locking! Due to having less friction, a holding brake is necessary: a electric motor 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 protection, cost-efficiency, and toughness mandates of the application. High strength bronze worm gear can be used, the payloads from 0.5T to 100T . A complete of 11 sizes are available, each in a journeying nut version and a simple version.

The screw jacks can be utilized separately or in groupings linked with drive shafts, joints, couplings, bevel gearboxes and additional mechanical components. In addition they could be driven by different motors: electric, with either AC electric motor 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 are basic, robust and inexpensive. The proportion of screw jacks that use ball screws is nevertheless constantly increasing. The reason why for this are mainly their pitch accuracy, 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. For this model screw jack, only the bronze nut move together with the screw shaft. The lifting screw will not slide. It can be like the linear actuator functioning theory which converts rotational motion into linear motion. Out of this point to understand, a power linear actuator is usually a motorized screw jack.

The screw thread of screw jack can 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 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.
