摘要:研究和发展新的中高速卫生纸机烘缸轴承故障诊断技术是造纸装备行业研究的一项重要课题。本课题在中高速卫生纸机烘缸轴承振动机理的基础上,结合烘缸轴承的自身结构和失效形式,研究了烘缸轴承内、外圈滚道和滚动体表面存在缺陷时的时域及频域特征,并给出固有振动频率及各种故障的振动特征频率方程。利用自主开发的故障诊断系统对实际测试数据进行快速傅里叶变换红外光谱分析发现,通过对中高速卫生纸机烘缸操作侧轴承进行状态监测,可以提取中高速卫生纸机烘缸轴承的振动特征,用于对烘缸轴承是否存在故障的在线判断。
Abstract:Research and development of fault diagnosis technology of new medium and high speed tissue paper machine dryer cylinder bearings are an important topic in the paper equipment industry. Based on the vibration mechanism of medium and high speed tissue machine dryer bearings, combined with the structure and failure mode of the dryer bearing, The characteristics of time domain and frequency domain were studied when the fault existed in the inner and outer ring raceways and the rolling element surface of the dryer bearings, and the equations of inherent vibration frequency and various fault vibration specific frequencies were purposed. Using the self-developed fault diagnosis system to carry out fast Fourier transform analysis of the actual test data, it was found that the vibration characteristics of the medium and high speed tissue machine dryer cylinder bearings could be extracted by monitoring the condition of the medium and high speed tissue machine operation ride dryer bearings. It could be used for online judgment on whether existed a fault in the dryer bearings.
