ZZ-Servolift®
ZZ-Servolift® gears are components for installing in machines and are exclusively for adjusting and positioning loads, workpieces and plant sub-assemblies with emphasis on plant installation and industrial automation. The screw jack unit ZZ-Servolift® is a compact gear unit and allows the integration of roller-ball spindles in a single-stage hypoid geared bevel gear box in the ZZ-Servoline® series. Due to the high degree of ef. ciency in lifting and lowering, the gears are not self-locking. With the screw nut and the basic model, two tried and tested functional principles are applied. Supplementary to the standard versions with roller spindles, swirled and for higher demands, polished spindles can also be used. With a spindle thread pitch (5 mm to 40 mm) and a bevel gear ratio (3:1 to 15:1), optimised to the selected application, various gear functions can be achieved – from precision adjustment gears through to fast screw-jack gears. The largest flexibility at the input side, is achieved by the modular concept of the motor flanges, whereby exchangeable and standardised motor flange plates can be installed at the dome on the gear side. The modular building-block system includes more than 120 different motor flange plates that allow the installation of almost all servomotors that are commercially available, on to the ZZ-Servolift® system. A direct drive without motor flange, i.e. by way of toothed belts, cardan shafts, etc., is also feasible. The ZZ-Servolift® takes into account all demands that may be placed on a modern gear concept. It combines the flexibility of a modular building-block system, resulting in a variety of applications, minimum torsional backlash, a high degree of rigidity, low overall weight, reduced mass inertia, high efficiency and with a universal fitting position, an operation that is almost free of any maintenance.
