| Abstract:Abnormal wear of connecting rod bearings occurred several times on a certain type of diesel engines, and all within short running time. Research was carried out on the design and application of relative components. The results show that the corner at the oil hole fillet of crank pin is too small and bad surface treatment of the bearing are the main causes. The improvement measures were given and proved to be effective by bench test and market feedback. |
