CALIPRI CW40 Wheel Profile Measurements

This feature makes possible a broad spectrum of applications and substantially reduces purchase costs, calibration costs and training costs. “ Wheel Profile” is the main module for the measurement of railway and tram wheel sets. This module allows for the measurement of an entire wheel profile cross section within a few seconds. Alongside the key wheel flange dimensions ( height, width, qR) , the wheel width, hollow tread as well as the rollover are determined. This module allows the measurement of the tyre thickness within a few seconds. The measurement is done in conjunction with the measuring of the wheel profile. The measurements of the tyre thickness inside / outside / groove are displayed together with the measurement parameters of the wheel profile. If the inside radius of the tyre is known, the diameter can also be concluded from this measurement. The “ Wheel Defect” module helps the user to differentiate critical defects from uncritical ones. When the defect is detected, an acoustic signal will sound and the width and depth of the defect are calculated. Flat spots as well as pittings are identified and measured. With regard to pittings, the measurement ranges are between 1 x 0.5 and 50 x 5 mm ( W x D) ; with regard to flat spots, between 15 x 0.1 and 80 x 2 mm ( W x D) . With the “ Radial / Axial Runout” module, it is possible to measure the ovality and excentricity as well as possibly existing lateral runouts of rail vehicle wheels. There is no special wiring or any rotary encoder required. Diameter changes are determined through the automatic combination of the measurement data on opposite sides of the wheel. An additional spectral analysis allows for more in-depth analyses, e.g. the detection of polygon formations of the wheel. The “ Wheelshop” module allows you to make an independent measurement of your wheel profiles for the wheel set machining. The depth of cut that is optimal for the respective wheel profile is calculated. The Wheel Shop module is applicable if your wheel set machine tool does not have any or a sufficiently exact measurement system or if the determination of the optimal depth of cut is to be done independently of the machine tool. All measurement results as well as the measured profile shapes will be stored electronically.
