摘要
介绍船舶动力的柴油发动机主机曲柄销严重烧蚀部位修复工艺的要点,详细介绍以曲柄销两端R圆角作为定位基准进行曲柄销磨削的工艺方案,保证加工后的曲柄销与曲轴主轴颈的平行度和加工后的曲柄销与原始中心线的同心度。
The paper describes how to repair the serious ablated area on the crank pin of the diesel engine for ships. The crank pin is grinded by using the radius on the two ends of the crank pin as the positioning reference to ensure the crank pin is parallel to the crankshaft main journal and the crank pin is coaxial with the original center line after grinding.
