Use of spherical roller bearing vibration - bearing maintenance technology knowledge

Spherical roller bearing vibration signal analysis and diagnosis method through the spectrum analysis of vibration signals of rolling bearing can be hidden danger in time precision diagnosis of rolling bearing fault reason 1, from the Angle of the frequency analysis can be seen that different frequency different just because of the failure reason of assembly structure caused by the vibration frequency is small when the spherical roller bearing components has serious manufacturing defects or damage in severe vibration frequency will be improved obviously. 2, from the impact pulse energy analysis when the spherical roller bearing components have a minor injury pulse value is small with the development of the fault pulse vibration intensity has obvious increase gradually. 3, monitoring method to determine whether the equipment normal spectrum graphics can use relative judgment standard lubrication time interval has a simple premise: in spherical roller bearing is not stopped by a dry and collapse operation under the condition of maintaining equipment reasonable running. This is a fixed concept of prevention. However, we must keep the balance between the lubrication excessive hunger and a lot of lubrication. Traditionally, the lubrication plan are set according to time. Equipment suppliers usually lubrication plan according to the operation time. And equipment suppliers in the process of their maintenance plan regularly for the amount of lubricating oil to join the instruction.
