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 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 equipment screw jacks are very precision and reliability, it could meet all the necessary basic safety, cost-efficiency, and sturdiness mandates of your application. High strength bronze worm gear can be used, the payloads from 0.5T to 100T . A total of 11 sizes are available, each in a vacationing nut version and a basic version.
The screw jacks can be utilized separately or in groups linked with drive shafts, joints, couplings, bevel gearboxes and other mechanical components. In addition they can be driven by different motors: electric, with either AC engine or DC motor and also hydraulic or pneumatic motors. All these motion control items could 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 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 accuracy, their high efficiency (much less power Worm Gear Jack consumption and 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 along with the screw shaft. The lifting screw will not slide. It is usually like the linear actuator operating theory which converts rotational motion into linear motion. Out of this stage to understand, an electric linear actuator can be a motorized screw jack.
The screw thread of screw jack could be acme screw and ball screw. So there are 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 more efficient as there are ball bearings between the nut and screw. The anti-friction ball bearing can increase the ball screw efficiency.
