ABSTRACT:
A wheel measuring machine includes juxtaposed first and second spindles relatively movable toward and away from one another for mounting a wheel to be measured therebetween. A first centering device is mounted on the first spindle to selectively center a first surface feature of the wheel on an axis. The second spindle includes a second centering device engageable with both the wheel and with the first spindle to selectively center a second surface feature on the axis when the first centering device disengages the wheel. A distance transducer sensingly engageable with a third surface feature of the wheel measures the distance between points along the surface feature and the spindle axis once when the first surface feature is centered on the axis and again when the second surface feature is so centered. From those measurements, parameter values describing dimensional relationships between the surface features are calculated.
