探讨洗衣机电机轴承应用中的振动与噪声问题

Analysis of the Vibration and Noise Problem in Bearing Application in the Motor of Washing Machine

本文针对一种洗衣机电机用滚动轴承6202 2Z,应用阶次分析等故障诊断方法,对轴承应用过程中几种典型故障带来的噪声与振动问题进行分析。滚动轴承每一个部分都有相应的特征频率,由此推测与轴承组装使用方面的问题,查找原因,寻求解决方案。电机作为洗衣机的动力源,是噪声优化改善的关键部件,而作为重点高速部件的轴承,优化其振动与噪声问题.则显得尤为重要。所以,轴承在应用方面的振动与噪声的故障诊断和分析,对电机的设计、生产、应用有着重要的指导意义。

In this paper,one type of ball bearing 6202 2Z is analyzed,which is widely used in the motor of washing machine.The author used Order analysis for the diagnostics of motor,and analyzed some typical problems in the application of bearing.Every parts of ball bearing have their own frequencies,and from this result,we can find noise source and get solutions.The motor is the power supply of washing machine,and it is a critical part to improve noise problem.The ball bearing holds high in working,so,to improve its vibration and noise is vital important.So it is useful to analyze the noise and vibration in the application of bearing,and it gives more instructions to motor design,production,and usage.
