Intelligent Balancing Solutions Balancing of general rotors Horizontal Hard-Bearing Balancing Machine UHK 16-26 • Balancing of any kind of medium up • with own bearing journals adapter frame • Balancing of rotors like • electro armatures The Hofmann balancing machines for balancing of any kind of rotors in manently calibrated. For a new rotor type the unbalance measuring system locations of the unbalance correction planes and the correction radii, only. Then the balancing process may in- stantly start. Time consuming calibrati- on runs are being omitted. Hofmann force measuring principle provide a high stiffness. The integrated piezo-electric force sensors are mea- suring the centrifugal force generated by the rotor unbalance on a direct way and with a very high sensitivity. As a benefit those sensors are not sensitive to temperature fluctuations and exter- nal electro-magnetic fields. As a result unbalances may be measured already at low speeds with a very high precise- • fast changeover • permanent machine • electronic protractor • high availability • Perfectly balanced workpieces through Hofmann force meas- uring principle • Universal application • Useful extensions based on a modular design To speed up the rotors to measuring speed, belt drives are being widely used. Their application is very flexible and their influence on the meas-uring result is small. End drives will be used to fast and safely accelerate rotors having a large moment of inertia. The unbalance measuring system MC 10 H provides a digital processing of the measuring data with a high selectivity for precision unbalance measurement. The Windows ® opera- ting system guarantees an intuitive, simple and reliable operation. The unbalance correction is being displayed in terms of mass-,

Balancing - made simple. Adjusting a Hofmann UHKbalancing machine for a given rotor is a matter of very few setups, only without the need of special tools. The positions of the bearing pedestals, idler rollers of the belt drive and the roller bearings are being adjusted using scales. In case of a belt drive the rotor will be retained by axial counter bearings. In case of an end drive with an universal joint shaft the drive unit overtakes the axial guiding of the rotor. The end drive with motor (and gear) can be axially repositioned to connect the rotor to the drive shaft. Therefore and also...

Safety comes first. Because of job safety balancing machines must be equipped with protective devices. That is required by many national and international laws - as is in the countries of the EU. Following the EU rules a balancing machine can be CE labelled only, if it is operated with an appropriate protection. The design of the protective device is mainly based on the hazardous potential of the rotor to be balanced. According to ISO 7475 a contact protection, safety class B, is to be applied, if any danger occurs when contacting rotating parts (for example cutting tools) or by trapping of...
