The BJ worm gear screw jack was created in several different versions and happens to be found in countless solutions within Healthcare, the meals Industry and other industries.
All worm equipment screw jacks may because standard be supplied with easy-to-clean and yellowish chromated surfaces with stainless steel spindles and meals approved lubricants.
If there are unique requirements for the design, we are very happy to offer adaptations also in smaller quantities.
The spindles can be protected from dirt and water by using protecting tubes.
Ball-screw jacks include a high-performance ball screw and nut that reduces the required input torque to about one-third the torque required for machine-screw jacks. 300 Series Stainless-steel screw jack are for conditions where corrosion resistance is essential. Stainless-steel lifting threads are precision formed to Class 2-C (centralizing) thread profiles.
The design is compact, simple and its own modular construction allows great flexibility in the decision of gear, installation options, flanges, oil types and surface treatments. The modular design is also ideal when there is a dependence on customisations where in fact the gearbox should be optimized for particular needs. That’s the reason why we are able to produce worm gear screw jacks adapted to your desires at an attractive price.
The worm gear screw jack allows for axial positioning and as well as our other items within the field of encoders, couplings and connecting shafts, it permits running more axial motions synchronously.
By connecting person screw jacks with drive shafts lifting systems could be realized in a simple way. With the rich accessories many problems can be solved with the typical program.
There are two basic types of screw jacks which a few additional styles originate. Initial, there are translating screw jacks. These kinds of screw jacks use a good start shaft or screw that travels into or out from the worm gear box. The lift shaft can either protrude from the installation flange aspect of the gearbox or from the top aspect of the worm equipment box. Secondly, are rotating type screw jacks. In this style, the lift shaft continues to be stationary and a lifting nut movements along the lift shaft. Similar to the translating screw jacks the screw can also protrude down from the installation flange or up from the top of the jack. To produce translation of the lift shaft or nut, both configurations should be secured to avoid rotation. Where that is unfeasible, keyed screw jacks are a choice.
Each model’s worm-gear-set arrangement uses an alloy-metal worm, which drives a high-strength bronze worm gear (drive sleeve). The worm shaft is backed on antifriction tapered roller bearings with exterior seals to prevent lack of lubrication. Machine-screw jacks feature a lifting shaft made of alloy steel with the very least tensile strength of 95,000 psi. Lead precision is approximately 0.004 in./ft.
