Automated gaging
system for control of geometric parameters of wheelpairs,
"Geopar" Series |
"Geopar-VKP"system. Application domain
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. |
Methods of control
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.
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
