| Abstract: | After the operation of monorail in Chongqing City for a period of time,oil leakage occurs in the oil seal of gearwheel locating shaft,that belongs to the speed measuring motor of individual train bogie gearbox,and the outer surface of the gearbox also shows bad appearance,greatly influencing the normal operation of monorail vehicle.Aiming at the speed measuring motor oil leakage fault,causes of the fault are analyzed based on an investigation of the matching surface quality,basic dimension,geometric tolerance,assembly process,processing technology,quality control of the related parts and many other factors,improvement measures and rational suggestions for the solution of motor oil leakage fault are proposed. |
