Abstract:In the measurement of the grinding of the traction motor of the locomotive traction machine，the reason for the oversize difference of the bearing position of the rotating shaft is analyzed，and the new type of cardtype outer diameter dial gauge for the traction motor of the locomotive is designed and manufactured. Through the practical application，the new type of card type outer diameter dial gauge ensures the grinding size of the bearing position of the traction motor shaft，the occurrence of the oversize of the shaft bearing position is avoided，the process and quality problems of the grinding position measurement of the locomotive traction motor shaft are solved.

Keywords:locomotive traction motor shaft；bearing position size tolerance out of tolerance；new type of card type outer diameter dial gauge
