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 additional machine screw actuators
No self-locking! Due to having less friction, a keeping brake is essential: a engine brake or a springtime pressure brake is required.
These worm gear screw jacks are extremely precision and reliability, it could meet all the necessary safety, cost-efficiency, and Worm Gear Jack durability mandates of your application. High strength bronze worm gear is used, the payloads from 0.5T to 100T . A total of 11 sizes can be found, each in a traveling nut version and a simple version.
The screw jacks can be used separately or in organizations connected with drive shafts, joints, couplings, bevel gearboxes and various other mechanical components. In addition they could be driven by different motors: electric, with either AC electric motor or DC motor in addition to hydraulic or pneumatic motors. All these motion control items could be built-in many type jacking system 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 are 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 accuracy, their high efficiency (much less power consumption and much less heat era) and the higher pitches offered, which permit higher stroke speeds.
A screw jack can truly add a machine cut lifting nut. Because of this model screw jack, only the bronze nut move along with the screw shaft. The lifting screw does not slide. It can be like the linear actuator functioning basic principle which converts rotational movement into linear motion. From this point to understand, a power linear actuator is 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 task. Compared with acme screw, the ball screw can be more efficient as there are ball bearings between the nut and screw. The anti-friction ball bearing can boost the ball screw efficiency.
