| Abstract: | Abnormal temperature rising of the axle-box of a new type metro vehicle's bogie is analyzed from bearing's lubrication status,manufacturing quality and related fit sizes.It is conformed that the main reason for this is the inaccurate size and tolerance on shape and position of fitting hole for bearing.The main reason is also validated by temperature rising experimentation. |
