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 keeping brake is necessary: a motor brake or a springtime pressure brake is necessary.
These worm gear screw jacks are very precision and reliability, it can meet all the necessary protection, cost-efficiency, and durability mandates of your application. High strength bronze worm gear is used, the payloads from 0.5T to 100T . A complete of 11 sizes can be found, each in a touring nut version and a basic version.
The screw jacks can be utilized separately or in groupings linked with drive shafts, joints, couplings, bevel gearboxes and various other mechanical components. They also could be powered by different motors: electrical, with either AC engine or DC motor along with hydraulic or pneumatic motors. Each one of these motion control items could be built-in many type jacking system arrangements or Worm Gear Jack configurations.
Ball screw jacks are normal where higher speeds and duty cycles are needed. Most screw jacks use trapezoidal screws Tr, because they are basic, robust and inexpensive. The proportion of screw jacks that make use of ball screws is however 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 obtainable, which permit higher stroke speeds.
A screw jack can 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 will not slide. It is usually like the linear actuator functioning basic principle which converts rotational movement into linear motion. From this point to understand, a power linear actuator is certainly a motorized screw jack.
The screw thread of screw jack could be acme screw and ball screw. So there are few variations of the screw jack. Commonly, machine screw jack and ball screw jack are available in your engineer project. Weighed against acme screw, the ball screw is better as there are ball bearings between your nut and screw. The anti-friction ball bearing can increase the ball screw efficiency.
