The influnce of lateral play of locomotives' wheelset on many issues

Based on analysing the relationship among the different lateral play and angle of attack and added impact load as locomotive running into curve,this paper discusses the influnce on decreasing wheel flange wear,burning loss of axle box bearing and axle suspension bearing,loosened and cracked on the schield ring of axle suspension bearing and crack of axle suspension bearing box,due to reducing lateral play of wheelset.
