电机的轴承噪声是小型异步电机的主要噪声源之一。电机轴承噪声和振动的大小取决于所用轴承动态特性之优劣——即单个轴承的振动加速度大小,这已是众所周知的。但是电机轴、轴承室加工对于电机的噪声、振动的关系,尚有不同看法。为此我们进行了一些验证,以供讨论、分析。一、轴承工作游隙对电机噪声、振动的影响每一个符合要求的轴承,均有一个符合国家标准要求的径向游隙。当它与电机轴、轴承室配合后,径向游隙要发生一些变化。这个变化后的游隙称为安装游隙。轴承在规 Motor bearing noise is one of the major noise sources for small asynchronous motors. Motor bearing noise and vibration depends on the size of the bearing dynamic characteristics of pros and cons - that is, a single bearing vibration acceleration, which is well known. However, the motor shaft, bearing chamber processing for the motor noise, vibration, there are different views. For this reason we conducted some verification for discussion and analysis. First, the bearing clearance work on the motor noise, vibration impact Each meet the requirements of the bearings, have a radial clearance in line with national standards. When it is with the motor shaft, bearing room with the radial clearance to be some changes. This change of clearance is called the installation of clearance. Bearing in the gauge
