Horizontal balancing machine with cradle type (tie bar type) pedestal
Motor armatures, Turbine rotors, Multi-cylinder crankshafts, etc.
Assembled rotor and stator, or low stiffness rotors can be balanced with cradle type (tie bar type) pedestal.
Roller bearing and/or V block bearing
Conventional balancing planes is up to 2 planes.
However, in case performing 2-plane balancing of rotary part of high speed rotary machine, check structure and shape of rotary part and select proper No. of Correction plane. Otherwise, it may cause higher order vibration of flexural mode under high speed rotation.
Sigma’s horizontal balancing machine expands No. of Correction plane until 4 planes at maximum, selecting proper No. of Correction plane freely. So the above mentioned problem can be solved easily.
