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 other machine screw actuators
No self-locking! Because of having less friction, a holding brake is essential: a engine brake or a spring pressure brake is necessary.
These worm equipment screw jacks are very precision and reliability, it could meet all the necessary basic safety, cost-efficiency, and strength mandates of your application. High power bronze worm gear is used, the payloads from 0.5T to 100T . A total of 11 sizes are worm screw jack available, each in a touring 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 can be driven by different motors: electric, with either AC 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 efficiency (much less power consumption and less heat generation) and the bigger pitches available, which permit higher stroke speeds.
A screw jack can add a machine cut lifting nut. Because of this model screw jack, only the bronze nut move combined with the screw shaft. The lifting screw will not slide. It is usually similar to the linear actuator functioning basic principle which converts rotational motion into linear motion. Out of 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 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 boost the ball screw efficiency.
