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 keeping brake is necessary: a electric motor brake or a springtime pressure brake is required.
These worm gear screw jacks are extremely precision and reliability, it could meet all of the necessary basic safety, cost-efficiency, and durability mandates of your application. High power bronze worm gear can be used, the payloads from 0.5T to 100T . A complete of 11 sizes can be found, each in a journeying nut version and a simple version.
The screw jacks can be used separately or in groups connected with drive shafts, joints, couplings, bevel gearboxes and other mechanical components. In addition they could be powered by different motors: electrical, with either AC motor or DC motor as well as hydraulic or pneumatic motors. Each one of these Worm Gear Jack motion control products can be built in many type jacking system arrangements or configurations.
Ball screw jacks are common 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 use ball screws is however constantly increasing. The reason why for this are primarily their pitch precision, their high efficiency (less power consumption and much less heat generation) and the bigger pitches available, which permit higher stroke speeds.
A screw jack can truly 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 certainly similar to the linear actuator operating principle which converts rotational movement into linear motion. Out of this stage to understand, a power linear actuator can be a motorized screw jack.
The screw thread of screw jack can be acme screw and ball screw. So there are few variations of the screw jack. Commonly, machine screw jack and ball screw jack can be found in your engineer project. Weighed against acme screw, the ball screw is definitely better as there are ball bearings between your nut and screw. The anti-friction ball bearing can raise the ball screw efficiency.
