起重机变速箱高速轴断裂的失效分析

High-speed Shaft Gearbox Failure Analysis

任何一类设备的整机安全质量,是离不开组成整机的零部件质量保障,其中零部件的制造质量是运行安全的基础。任何制造环节质量忽视都会导致设备灾难和人员伤亡。从一台正在使用的起重机,在装卸过程中突然发生货物坠落,造成重大物损事故的原因,来分析其失效原因并重申产品零部件制造质量及热处理工艺环节的重要性。

The manufacturing quality of parts and components is foundation to run securely. Any manufacturing process quality ignorance will cause the device to disaster and loss of life. Base on a accident of cargo dropping during a crane being used in handling and resulted in significant goods damage, the author found out that it was due to failure analysis and reiterated the importance of the quality of heat treatment.
