1.为实现轴承的不分解检查,研究了测量SPM(每分钟冲程数)的辅助转动机轴承诊断技术,并制定了判定标准。对于齿轮传动装置,研究了简易且精密的振动测试技术,在传动装置上加轴向力,用综合分析总输出值(O/A值)和机壳振动频谱的方法,可检查转动机上1mm范围的裂纹。 2.为降低成本,有必要修改新干线电车车轴的检修周期、限度和作业标准。除作好高频淬火车轴裂纹发展规律试验的准备工作外,还用依据威布尔分布的最大估算法,明确了车轴残存率的概算结果,得出只要防止蠕动裂纹和车轮移位造成的擦伤裂纹车轴寿
1. In order to realize the bearing non-decomposing inspection, the auxiliary bearing diagnosis technology of measuring the SPM (number of strokes per minute) has been studied and the criterion has been established. For the gear transmission, a simple and precise vibration test technique was studied. The axial force was added to the transmission. A comprehensive analysis of the total output value (O / A value) and the vibration frequency spectrum of the housing could be used to check the 1mm range Crack. 2. To reduce costs, it is necessary to revise the inspection intervals, limits and operating standards for Shinkansen tram axles. In addition to the preparation for the test of the crack growth law of the high-frequency quenched axle, the estimated result of the axle residual ratio was also determined by using the maximum estimation method based on the Weibull distribution. It was concluded that as long as the prevention of the creeping crack and the abrasion caused by the wheel displacement Cracked axle life
