PERFORMANCE SPECIFICATIONS for Model B750RR Balancing Machine 1.1 Balancing Machine The Model B750RR is a dynamic, horizontal axis, super critical (above resonance) Balancing Machine that utilizes velocity transducers to measure the displacement generated by unbalance. The B750RR has an end drive console with a variable speed motor and multi‐ speed gearbox for efficient transfer of torque to the rotor. The end drive system uses a Cardan shaft to spin the rotor. Adapters to attach the rotor are the customer’s responsibility. The use of a Cardan shaft may require electronic tooling compensation (a feature of the Model 295 instrument) to eliminate errors due to fit up and /or unbalance in the adapter tooling. The machine and instrument are easy to use and set up. The standard calibration method uses trial weights to calibrate the rotor to the balancing instrument for the most accurate possible unbalance readout. The machine can be mounted to most industrial floors without modification. 1.2 Instrumentation The standard balancing instrument available with the B750RR is the Model 295, which has large digital display meters and shaft synchronous digital filters. Dynamic (left/right), static, and couple unbalance can be displayed. Individual rotor setups can be stored and the balance results can be printed on a printer that is also included with the B750RR. The instrument also displays the angular position of the rotor to aid in placing the correction weights. Detailed specifications of the Model 295 instrument are separate from these performance specifications.
