Horizontal Hard-Bearing Balancing Machine H-9.1 - 1

Balancing of general rotors Horizontal Hard-Bearing Balancing Machine H-9.1 Advantages High productivity by fast change over Hofmann-force-measuring principle for high-precision unbalance measuring and high machine availability Protractor Posiquick C for exact transfer of the unbalance position to the rotor Compact and space saving design Application Balancing of any kind of very small rotors with own bearing journals on an auxiliary shaft as complete assembly in an adapter plate Applicable in manufacturing (single or series) maintenance design and development Balancing of rotors like electric armatures turbochargers small turbines Description The Hofmann balancing machine H-9.1 is particularly designed for the requirements of balancing any kind of rotors in the weight range up to 5 kg. Just a few maneuvers are necessary to adapt the pedestals and the belt drive to another rotor type. The hard-bearing machine is permanently calibrated. For a new rotor type the unbalance measuring system has to simply be set to the specific locations of the unbalance correction planes and the correction radii, only. Then the balancing process may instantly start. Time consuming calibration runs are being omitted. 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 ® operating system guarantees an intuitive, simple and reliable operation. The unbalance correction is being displayed in terms of mass-, unbalance- or correction-units. The pedestals comprising the Hofmann-force-measuring principle provide a high stiffness. The integrated piezo-electric force sensors are measuring 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 external electro-magnetic fields. As a result unbalances may be measured already at low speeds with a very high preciseness. Typical rotors
