许多研究人员通过在轴承座圈上某个点采集轴承座圈振动速度、加速度或位移样本来研究滚动元件轴承的振动，轴承在某种程度上隔离的环境中运行。虽然这些方法在轴承产生的噪声的评估和改善方面取得了相当大的进展，但方法的改进一直是一个不断发展的趋势。在这个过程中的一个有希望的步骤在这里报告。本文讨论了用加速度计轴向测试代替加速度计径向测试，用金属指数变幅杆连接轴承和加速度计。喇叭技术避免了加速度计应变灵敏度和结果依赖于加速度计相对于特定轴承异常的角取向的问题。
A number of investigators have studied the vibration of rolling element bearings by taking samples of bearing‐race vibratory velocity, acceleration, or displacement at one point on the race, the bearing being run in a somewhat isolated environment. While such methods have led to considerable progress in the evaluation and amelioration of bearing‐generated noise, there has been a constant trend toward improvement of the methods. One promising step in this process is reported here. The present paper discusses the replacement of accelerometer radial testing by accelerometer axial testing, the new connecting link between bearing and accelerameter being a metallic exponential horn. The horn technique avoids problems of accelerometer strain sensitivity and dependence of results upon accelerometer angular orientation with respect to specific bearing anomalies.
