MM 340 STATIC AND DYNAMIC BALANCING MACHINE
GENERAL DESCRIPTION

    The machine is used for studying of balancing principles. 

    A rotor shaft is connected to the motor by a double universal joint and rests on two supports with adjustable distance between supports. Each support holds the shaft in place by three bearings with crest. Two standard rotors and two radially slotted rotors are provided for various cases of balancing. The unbalance forces are picked up by two vibration transducers and converted to digital signals. The speed is adjusted by an inverter and speed signal is provided by a sensor. The magnitude and angle of the unbalance for each plane is analyzed and displayed on a computer (separately supplied). The vibration and speed transducers are removable for field use. A note book computer is recommended for field use but is not included in the scope of supply. A transparent cover is provided for safety.

TYPICAL EXPERIMENTS
  • Single plane balancing.
  • Two planes balancing.
  • Balancing machine calibration.
  • Single plane field balancing.
