Schenck Horizontal Balancing Machine Hm6-Hm80

Product Description

Universally applicable with modular design;
High precision and efficiency
Safe handling through economic design concept;
Hard-bearing principle ensures quick change-over from one workpiece to the next;
Permanent Calibration, time and cost savings by elimination of calibration runs;
Provides for correction in two planes or separate correction of static and couple unbalance
Optional with belt drive and universal-joint drive for different type of rotors.
Advance measuring instrument CAB708, optional CAB 920 - the high end solution
Upgradeable by many additional modules e.g. for mass correction With the appropriate machine design and a suitable protection device the machines can also be used for high-speed balancing: Bearing
force monitoring for automatic shut-down in case of overload;Contact-free measurement of concentric running of rollers Shielded sensor en case of magnetized rotors
Range of Application
Universal balancing machines series HM6-HM80 offers high precision and a wide application. It features permanent calibration, ergonomic structural design, and a user-friendly operating system. This machine is suitable for balancing both rigid and flexible rotors, weighing between 500KGS to 250T
Typical applications are:
Blowers and fans for a variety of industries
High-speed and low-speed rollers for paper and thin sheet production
Electrical short-circuit armatures and generators for the electrical industry
Separators / centrifuges for water processing.
The length of the machine bed is dependent on the length of the rotor, the required height of the bearing pedestals is determined by the rotor diameter. If the rotor is mounted on its own bearing journals, these will be supported by roller carriages. Depending on the requirements imposed by the rotor, sleeve bearings may also be used.
Rotors requiring high torques are driven through variable-speed gearboxes and universal joint shaft. Lightweight rotors with smooth surfaces may be driven with the help of a belt drive system.
Schenck universal balancing machines series HM are a highly efficient investment both for one-off rotors and for small batches.
