Specification :

NOSEN offers a powerful, reliable and complete worm gear Screw Jacks Lift Systems for the electromechanical adjustment of linear movements.

Comfigurations: Worm gear screw jacks, spiral bevel gearboxes, flexible linking shafts, couplings, additional guides, electric motors etc.

Worm gear screw jack systems is of heavy duty, self-locking, positioning precision, uniform lifting speed and fully synchronized.

Worm gear screw jacks is used in table that have extremely high capacity requirements of need very precise up or down control. Because the screw jack systems are of high mechanical, they are an excellent choice when hydraulic, pneumatic or chain systems are prohibitive choices.

Before starting assembly work, the direction of rotation of all worm gear screw jacks, spiral bevel gearboxes and the drive motor must be checked with regard to the feed direction of each individual worm gear screw jack.

All the components must be carefully aligned during assembly. Alignment errors and stresses increase power consumption and lead to overheating and premature wear. Before a drive unit is attachmed, each worm gear screw jack should be turned through its entire length by hand without load. Variations in the amount of force required and/ or axial marks on the outside diameter of the screw indicate alignment errors between the worm gear screw jack and its additional guides. In this case, the relevant mounting bolts must be loosened and the worm gear screw jack turned through by hand again. If the amount of force required is now constant throughout, the appropriate components are aligned. If not, the alignment error must be localized by loosening additional mounting bolts.
