导语:轴承处于良好的连转状态时会发出低低的“呜呜”或“嗡嗡”声音,而在我们工业生产中,轴承异响时常发生,且故障排除并非易事,今天就由小编来帮大家找到原因及处理方法。
异常轴承响声
大的金属噪音
原因1:异常负荷。
对策:修正配合,研究轴承游隙,调整与负荷,修正外壳挡肩位置。
原因2:安装不良。
对策:提升轴、外壳的加工精度,改善安装精度和安装方法。
原因3:润滑剂不足或不适合。
对策:补充润滑剂或选择适当的润滑剂。
原因4:旋转零件有接触。
对策:修改曲路密封的接触部分。
规则噪声
原因1:由于异物造成滚动面产生压痕、锈蚀或伤痕。
对策:更换轴承,清洗有关零件,改善密封装置,使用洁净的润滑剂。
原因2:(钢渗碳后)表面变形。
对策:更换轴承,注意使用状况。
原因3:滚道面剥离。
对策:更换轴承。
不规则噪声
原因1:游隙过大。
对策:研究配合及轴承游隙,修改预负荷量。
原因2:异物侵入。
对策:研究更换轴承,清洗有关零件,改善密封装置,使用洁净润滑剂。
原因3:球面伤、剥离。
对策:更换轴承。
检测方法与仪器
目前检测轴承异常声有两种途径。一种是基于声学的噪声检测法,另一种是基于振动的检测法。此外,还有相关仪器可进行诊断。
噪声检测法
是在基础噪声小于20db的消音环境下,使用高质量的麦克风以一定的距离和方向提取轴承声压信号,并经一定的分析方法提取其中的异常声成分,是异常声的直接测量方法。
震动检测法
是异常声的间接检测方法,又可分为定性检测法和定量参数检测法。其中,定性检测法又分为监听异常声法和观察振动波形法。定量参数检测法是指用被测轴承振动信号中与异常声有关的实测参数值如:振动的峰值,波峰因数来评价轴承的异常声。
测量仪器
测量轴承异常声的测量仪器很多,例如:杭州轴承试验研究中心的BANT-1型轴承异常声监测仪;上海轴承技术研究所的S092轴承振动(异常声)测量仪;洛阳轴承研究所与大连轴承仪器厂联合研制的S0910-Ⅲ。这些轴承测量仪器可以测量轴承振动的有效值又可以测量反映轴承异常声参数的峰值,峰值因数和脉冲数等。
总结
轴承异响主要由以下因素导致:
油脂有杂质
轴承润滑不足
轴承的游隙太小或太大
混入砂粒或碳粒等杂质,起到研磨剂作用
混入水份、酸类或油漆等污物,起到腐蚀作用
轴承被座孔夹扁
轴承座的底面的垫铁不平
轴承座孔内有杂物
密封圈偏心
轴承受到额外载荷
轴承与轴的配合太松
轴承旋转时过紧
