    • ZZ-Servoline® Type KN

    • ZZ-Servoline KN has been designed as a bevel gear unit especially for high-dynamic servo drives in automation techniques. With the hypoid gearing, gear ratio's of up to i = 15:1 can be covered in one stage. The design of the gear takes into account a weighting according to requirements, between pitting, fatigue fracture, the loading capacity on the root of the gear tooth and gear scuffing.

      The gear unit is suitable for operating in any optional mounting position. The output shaft can be in the form of a single or double-ended solid shaft, or as an extended hollow shaft with external taper lock assembly. The various combinations of shafts and flanges, provide facilities for all commonly used servo motors.

      Technical Features:
      • 6 Sizes of gear units
      • up to 1400 Nm
      • up to 8000 rpm

    • ZZ-Servolift® Bevel-gear screw jack units

    • 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.

    • Gear components are the key items manufactured by ZZ-Antriebe GmbH. They form the basis of the success of our company. Our high quality´bevel gear wheels are produced in accordance with the Klingelnberg design and enjoy a tremendous reputation for quality. They are used in ZZ bevel, superimposed and high-speed lifting gear units. In addition our gear wheels can be optimally applied in many customeroriented applications (e. g. machine tools, textile machines, printing machines, commercial vehicles, plant construction, etc.).

      All ZZ cam mechanisms are fitted with through hardened and ground cams. This is the basis for high precision, positive action and long service life. A cam set converts a uniform input turning motion into stepped or oscillating output movement, which can be optimized for every application. The housings made of cast - iron or aluminium are fully machined.

    • Indexing Tables

    • The perfect components for movements, cycling and positioning

      ZZ-indexing tables have proven their worth in various applications as for example packing machines, print- printing machines or assembling systems. They allow a high controlled cycle time together with low maintenance effort. They are suitable for absorbing high axial forces as large torque and moments of tilt. Within dwell phase there will be an interlock which also permits sensitive process operations on the part – together with high repetition accuracy. The output shaft is provided with a machined surface to take up an assembling platform.
