The systems are designed for making automatic measurement of geometric parameters of railway wheel sets in the course of incoming and outgoing inspections carried out in railcar/wheel shops, wagon depots.
"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.
- 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.
- 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.
- 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.

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.
