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 various other machine screw actuators
No self-locking! Due to the lack of friction, a holding brake is necessary: a motor brake or a springtime pressure brake is necessary.
These worm equipment screw jacks are very precision and reliability, it can meet all the necessary security, cost-efficiency, and durability mandates of your application. High worm screw jack strength bronze worm gear can be used, the payloads from 0.5T to 100T . A complete of 11 sizes are available, each in a traveling nut version and a simple version.
The screw jacks can be utilized 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 along with hydraulic or pneumatic motors. All these motion control products can 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’re basic, robust and inexpensive. The proportion of screw jacks that make use of ball screws is nevertheless constantly increasing. The reasons for this are primarily their pitch precision, their high efficiency (much less power consumption and much less heat generation) and the higher pitches obtainable, 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 together with the screw shaft. The lifting screw will not slide. It is like the linear actuator functioning basic principle which converts rotational motion into linear motion. From this point 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 are there few variants of the screw jack. Commonly, machine screw jack and ball screw jack are available in your engineer task. Weighed against acme screw, the ball screw is more efficient as there are ball bearings between your nut and screw. The anti-friction ball bearing can raise the ball screw efficiency.
