Servo gearbox
Servo planetary gearbox
ZF Servo plan planetary gearboxes were developed for the direct mounting at servo motors. Through different scales and a basic add-on system they are in almost all areas of the automation applicable.
The servo gears bid together with a servo motor a coaxial drive and output. Across a force-fit clamp coupling the output wave of the servo motor is connected with the sun gear of the servo gear. This sun gear actuates three planetary gears stored in a planetary bearer. They role off a hollow wheel with internal gear. Through the division on three planetary a balanced stress distribution results and guides therefore to a very compact design with high power density.

Rack & pinion
Wide range of racks
We do offer a wide range of racks as standard program. Especially in the area of high quality racks we do cover the whole range of possible versions for your application.
Machine tool gearbox
ZF Duo plan 2K
The ZF Duo plan two gear control gear finds basically application in machining tools, test beds and in application which need a high torque.
Through the different component equipments the gear can for example be used for turning centres (horizontal B3/B5) or conditioning centres (vertical V1/V3). The gear is additionally installed in different machines, in which a boost of the torques and respectively the engine speed is required.
Advantages
A machine tool should universally be applied, to be able to handle different materials. The ZF-Dou plan two gear control gear enables this.
Force + Dynamic
High cutting rates for soft materials and high cutting forces for hard materials are required. These can reached through the application of a switchable gear, whereby the high torques of the drive motor (I = 1:1) are retained, but additionally multiplied the drive toque of the motor through the conversion (e.g. I = 4,00) and the torque is reduced about the same factor.
Flexible
The cutting capacity is consequently constant and is available across a wide torque range. Only through a gear this flexibility is reachable low-priced. Direct arbour extension (INLINE + TSC) These gears are mounted directly at the arbour, no belts are required. The gears are especially applicable for high torques in the working tool production.
Torque and output
Depending on the motor adjustment range with constant output you can reach adjustment ranges of constant output up to 1:20 at the main arbour with the gears. Therefore on the one hand high torques result in the lower range of speed and on the other hand high speeds, with which you can exploit the cutting capacity of modern tools.

Clutches & brakes
Hysteresis brakes, Hysteresis couplings
- Contactless torque transmission
- 4 scales
- Nominal torque up to 38 Nm
- Continuous adjustable torque
- High slip power in continuous duty (up to max. 4000 W)
ZF Tiratron, i.e. the combination of break with the control electronics respectively coupling with control electronics enable both the exact regulation of tractions and also a defined adjustment of torques.
Exemplary application areas
Application possibilities for the ZF hysteresis technology are located everywhere, where products e.g. paper, wires in winding processes are processed. On dynamometers or in ergometers burdens can be simulated with Tiratron.
Contactless torque transmission
The break or coupling transfuses the continuous adjustable torque contact less across air gaps, consequently constant and wearless. No maintenance required.
Continuous adjustable torque
The break torque and respectively the assignable moment only depends on power. It’s as far as possible independent from speed and is constant available from the deadlock to maximal torque.
High slip power in continuous duty, overload capability
The breaks of the power optimized series absorb high continuous slip powers. A momentary overload is therefore also possible.
The system,
consisting of break and coupling and universally applicable control electronics, bids pre-assembled solutions to many applications.
Effectiveness
The function of hysteresis breaks and couplings is due to magnetic action of force of gravitating poles in the synchronisation and constant unmagnetized of a constant magnetic material in the slip handling.
ZF Single disc friction system
Electro magnetic used single disc couplings and breaks are used for automation of mechanic working ways in the production of machines and apparatuses due to their simple design and their advantageous outside scales, e.g. for textile machines, packaging machines, printing and paper machines, machine tools and welding machines, bureau machines u.a.m. (?). The single disc couplings and breaks are used e.g. for switching of torque and speed stages, for controlling of trajectories with positioning or for disengaging of machines with blockage.
Assembly and Effectiveness
The couplings and breaks are without abrasive ring and with low maintenance. From special advantage the double magnetic ampere turns of the anchor plate, where the action of force of the magnetic field is used double. Thereby big torques are achieved at small outside scales and the big passage. Both frictions surfaces consist of metal. Through the missing of the else wise normal for single disc couplings organic friction linings these couplings are especially environment friendly. They are applicable for dry and wet use. The couplings and breaks reach their nominal torque after a short come in or few circuits under the rotational speed difference (see Chapter 4.1. handling general advice). They are callous in the dry handling against exiguous contamination through oil and fat. The torque gets radial backlash free transmitted through a diaphragm spring which is frontal connected with 3 respectively 6 points with the anchor plate and which is affixed with the analogue with 3 screws.
