  • Device and method for calibrating an underfloor wheelset lathe without a calibration wheelset
    Patent number: 11453061
    Abstract: The invention relates to a device (22) for calibrating an underfloor wheelset lathe (3) without a calibration wheelset, comprising; a motor (23) with a rotational axis (D), a friction roller (24), and a measuring bridge (18), wherein the friction roller (24) is connected p a driveshaft of the motor (23). The aim of the invention is to allow a simpler calibration without a calibration wheelset. This is achieved in that the friction roller (24) has an approximately cylindrical frictional surface with a defined nominal diameter. The invention additionally relates to an underfloor wheelset lathe (3) comprising such a device (22) and to a method for calibrating an underfloor wheelset lathe (3).
