ADDITIONAL OPTIONS:
Option of orienting the wheelset in the angular position to the elimination point for each plane automatically at the push of a button by the operator.

For balancing wheelsets with a reducer in the middle of the axis, there is a jack supporting the reducer housing, and allowing to carry out balancing without disassembling the reducer housing.

Machine’s working area protective guard.

 

Design features of the machine

Wheelsets balancing is carried out when they are installed by inner rings of roller bearings, or by centering plugs of roller bearings, on the roller bearings of the machine.

Machine’s wishbone suspension with bearing hinges and low self resonance frequency guarantees high accuracy of balancing.

Rotation of the wheelset during balancing is performed by a cardan axial drive.

Asynchronous variable-frequency electric drive allows to perform infinitely variable speed control without stopping the motor, choosing the optimal modes for balancing.

 

 

Self-aligning supports with cylindrical reinforced rollers exclude the possibility of traces of “rolling” on the mounting (bearing) necks of the rotor with low hardness and large mass.

Jacks for smooth installation and removal of the wheelset from the supports ensure the protection of the machine’s mechanisms from impacts, create convenience and safety in process of work.

PAK-1 BALANCING SYSTEM

Digital system is based on an industrial fanless computer with a touch screen and a measuring unit.

Set-up mode by “triple start-ups” method with the use of calibration weights on the serial rotors with initial unbalance.

Calibration of the machine is made by the operator enabling to reach the maximum sensitivity of the machine, thus exempting from the duty to pay annual calibration fees.


The system provides measurement of the imbalance in the polar coordinate system in two planes with the display of the magnitude and angle of imbalance, both relative to the axis passing through the geometric centers of the wheels, and relative to the axis of rotation of the wheelset.

  • Calculation of the balance tolerance values in default of technical documentation for the balancing product.
  • Value calculation of the correction test weights to simplify the tuning process for the balancing rotor.
  • Real-time balancing display, i.e. if there is any defect or a hindrance of a rotor, it’s visible immediately as fluctuation in measurement result.
  • View of unbalance value in grams, gmm, gsm, gmm / kg optionally.
  • Taking into account the eccentricity of the balancing mandrel.

 

  • Unbalance distribution on n-planes correction
  • Calculation of hole depth for correction of unbalance.
  • Possibility of decomposition of correcting weights into structurally conditioned anchoring points (blades, fans, slots).
  • Rotor balancing report creating and printing.
  • USB port for printer connection, USB-flash memory, port for connecting to local network and Ethernet network.
