| Abstract: | The paper analyzed the fracture of the driving bevel gear screw part which caused the whole axle out of run. By testing and measuring the dimensions and material quality associated with the driving bevel gear,finally found out that the size of the 30312 bearing journal fell out of the technical requirements.When the axle was in run,the slide and rotation was happened on the 30312 bearing,then the flange without thermal refining which major diameter fit of the driving bevel gear's spline happened heavy wear,... |
