1.reverse the monitoring and diagnosis of roller bearings, is a long-term and periodic strong work, equipment under test needs to run under load conditions, and test equipment condition, measuring positions, apparatus Wanfang should be the same.
2.lf-aligning roller bearing vibration other than composition bearing vibration signal detection of sources of interference, is the greatest obstacle to implementation of the shock pulse method for diagnosis, to identify and eliminate the interference factors.
3. Establishment of discriminant standard size of the shock pulse amplitude associated with the bearing speed, size, also says that the severity of the injury. Current shock pulses after maintenance in good condition sold in shock pulse amplitude test instruments have to be normalized. Has nothing to do with the speed and size of the bearing, relevant only to the spherical roller bearing. Bearing fault diagnosis instrument to establish standards to determine if there is a failure of the bearing and gravity of the fault, pulse value relationships with bearing State.
