第三讲滚动轴承的振动和噪声这个问题为大家所关心。因在生产和运行中,人们往往希望通过轴承的振动和噪声准确而简便地判断轴承的技术状态,对轴承进行技术诊断,预防失效,以便提高电机的可靠性。但由于轴承的振动和噪声现象相当复杂,影响因素也较多,因此在实际生产和运行中要想在这方面制订出一个明确的标准,目前仍有困 Lecture 3 Vibration and noise of rolling bearings This issue is of concern to everyone. Because in the production and operation, people often hope that the bearing vibration and noise through accurate and easy to determine the technical status of the bearing, the bearing technical diagnosis, to prevent failure, in order to improve the reliability of the motor. However, due to the bearing vibration and noise phenomena are quite complex and more influential factors, so in the actual production and operation in this area to develop a clear standard, there are still difficulties
