Research on Failure Analysis and Solution of Cracking of Outer Ring of Cone Gear Bearing in a Certain Type of Engine
This article analyzes the design,technology,processing,assembly,and metallurgy of a certain type of turbine-shaft engine's bevel gear bearing,confirming that the cracking of the bevel gear bearing is caused by the remelting layer at the transition R of the outer ring's installation edge.Improvement measures such as the use of filing and polishing on the outer surface of the bevel gear bearing and the use of grinding wheel dressing and polishing at the transition R of the installation plane are proposed.Operational procedures for replacing bevel gear bearings in the field are formulated,which have certain reference value for troubleshooting similar bearings.
