  • "Geopar-VKP"system

    The  system is designed  for making automatic measurement of 27 geometric parameters  of wheel pairs of wagons in  the course of  incoming and outgoing inspections carried out in railcar/wheel shops,  wagon depots and  wheelpair repair and gathering workshops.

     

    Parameters under control

    Wheel parameters:  out-of-roundness, deviation of  roll  surface  countour from  desired profile, wheel flange parameters, wheel tread width and thickness,  defects on rolling surface, and wheel separation distance.

    Axle  journal  parameters:  average diameters underneath the first  and second bearings, out-of-roundness and taper. 

    Axle parameters:  diameters  and  ovality  of  pre-wheel-seat  parts, diameters  of  wheal seats  and middle parts of axle

  • "Geopar-LKP"system

     The system is intended for use in automated measurement of  17 geometric parameters of  locomotive wheelsets in the process of repair.

     

    Parameters under control

    Wheel parameters controlled:  diameter and out-of-roundness of wheel tire over the rolling circle, wheel tire thickness and width, flange thickness and height, deviation of  the rolling surface profile from maximum profile values.

    Controlled parameters of a toothed gear wheel:  tooth thickness

    Controlled parameters of a wheelset:  the distance between inner lateral faces of tires, hubs and gear wheels. 

    Controlled parameters of a wheelset axle:  box journal diameters, pre-wheelseat parts, middle axle parts, diameter of journal for motor-axle bearing

  • "Geopar-KC" System

    The system is intended for use in automated measurement of  8 geometric parameters of wheel centres  in the process of repair.

     

    Parameters under control

    Rim diameter, variability of diameter along lateral and longitudinal sections, rim diameter difference, inter-rim distance,  inter-rim distance difference, rim radial runout, rim width.

Operation

Measurement of all parameters is performed by means of noncontact  techniques during one revolution of a wheel pair fixed to rotate on centres. 

Rolling surface contour and wheel dimensions are measured by using Series RF620 2D laser scanners.

Precision measurements of axle journal diameters are made by  means of  Series RF656 optical micrometers.

Other parameters are measured with Series RF603 triangulation laser sensors.
