检查单体轴承噪声通常是在隔声、隔振的试验室内将轴承装在驱动装置上(以下简称驱动器)施加一定数量的负荷,然后用声学仪器测试.显然,轴承噪声的测试和试验室条件、声学仪器性能、传声器位置(话筒位置)、驱动器性能以及施加负荷方法,轴承润滑方法等有关.从图1和图2两次装机试验看出:轴承噪声和电机噪声之间规律不一致,相差很大.这两次试验用的轴承都是分别在同一时间,同一地点及同一试验条件下按1963年提
Check the single bearing noise is usually in the soundproof, vibration isolation laboratory bearing installed in the drive (hereinafter referred to as drive) to impose a certain amount of load, and then use acoustic instruments test.Obviously, the bearing noise test and laboratory conditions , Acoustic instrument performance, microphone position (microphone position), actuator performance and method of applying load, bearing lubrication method, etc. From the two installed tests in Figure 1 and Figure 2, it can be seen that there is inconsistency between the bearing noise and the motor noise, Large. The two test bearings are at the same time, the same place and the same test conditions by 1963 to mention
