Spherical roller bearing vibration signal analysis and diagnostic methods through the spectrum analysis of vibration signals can be found hidden in a timely manner of sophisticated diagnostic Rolling the cause of the malfunction

1, from the perspective of frequency analysis

When the spherical roller bearing components can be seen that the frequency of different reasons for the failure of the corresponding frequency vibration caused just because the assembly structure small serious manufacturing defects or damage severe vibration frequency will be markedly improved.

2, the pulse energy from the impact analysis

With the failure of development pulse values ??gradually increase the vibration intensity when the pulse is very small spherical roller bearing components have minor damage also increased significantly.

3, the monitoring method

Whether it is normal for the spectrum in Fig judge equipment relative criteria

The lubrication interval has a simple premise: to maintain a reasonable operation under conditions of spherical roller bearings stops running dry and crash. This is a fixed concept of prevention. However, we must maintain a balance between the lubrication thirst and excessive lubrication.

Traditionally, the lubrication program is scheduled. Equipment suppliers usually depending on the operating time to develop lubrication plan. And equipment suppliers often added to the amount of lubricating oil in the maintenance plan process guidance.
