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 efficiently than various other machine screw actuators
No self-locking! Due to having less friction, a keeping brake is necessary: a motor brake or a springtime pressure brake is necessary.
These worm gear screw jacks are extremely precision and reliability, it can meet all of the necessary safety, cost-efficiency, and toughness 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 journeying nut version and a basic version.
The screw jacks can be utilized separately or in organizations linked with drive shafts, joints, couplings, bevel gearboxes and various other mechanical components. In addition they 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 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 make use of trapezoidal screws Tr, because they are simple, 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 precision, their high worm screw jack efficiency (much less power consumption and less heat generation) 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, just the bronze nut move together with the screw shaft. The lifting screw does not slide. It is certainly like the linear actuator working principle which converts rotational movement into linear motion. Out of this stage to understand, an electric linear actuator is certainly a motorized screw jack.
The screw thread of screw jack can be acme screw and ball screw. So are there few variations of the screw jack. Commonly, machine screw jack and ball screw jack can be found in your engineer project. Compared with acme screw, the ball screw can be better as there are ball bearings between your nut and screw. The anti-friction ball bearing can raise the ball screw efficiency.
