<p>An apparatus for driving a railway wheelset in a wheel machining device. The wheelset including opposing wheels 6,7 rotatable about a longitudinal axis. The apparatus including at least one drive assembly 11 for contacting a sidewall of at least one wheel 6,7 to thereby impart rotational motion to the wheelset, and a positioning mechanism 13 operatively connected to the drive assembly 11 for positioning the drive assembly 11 with respect to the wheel 6,7. In use, as the wheel 6,7 is rotated by the drive assembly 11, the drive assembly 11 is free to move relative to the positioning mechanism 13, in unison with back and forth lateral movement of the wheel's sidewall caused by uneveness in the wheel's sidewall.</p> |
