worm screw jack

Worm Gear worm screw jack 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 various other machine screw actuators
No self-locking! Due to the lack of friction, a keeping brake is essential: 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 strength mandates of the application. High power bronze worm gear can be used, the payloads from 0.5T to 100T . A total of 11 sizes can be found, each in a journeying nut version and a basic version.

The screw jacks can be used separately or in groups linked with drive shafts, joints, couplings, bevel gearboxes and various other mechanical components. They also could be driven by different motors: electric, with either AC motor or DC motor and also 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 normal 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 use ball screws is nevertheless constantly increasing. The reasons for this are mainly their pitch precision, their high efficiency (much less power consumption and much less heat generation) and the bigger pitches available, 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 together with the screw shaft. The lifting screw does not slide. It is usually similar to the linear actuator working theory which converts rotational motion into linear motion. Out of this stage 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. Weighed against acme screw, the ball screw can be better as there are ball bearings between your nut and screw. The anti-friction ball bearing can increase the ball screw efficiency.
