Spherical roller bearing vibration signal analysis and diagnosis by spectral analysis of vibration signals can detect hidden reason precision rolling bearing fault diagnosis
1, from the point of view of frequency
As can be seen in different vibration frequencies corresponding to the different causes of failure frequency simply because the assembly structure caused when a small spherical roller bearing elements of manufacturing defects or serious injury serious vibration frequency will be significantly improved.
2, the pulse energy from impact analysis
When the spherical roller bearing element having a small pulse value minor damage with the development of the fault pulse value increases of intensity also increased significantly.
3, monitoring methods
For the spectrum can be used to judge whether the device is properly relative criteria
Lubrication time interval has a simple premise: the spherical roller bearings to keep the equipment running, without reasonable cause drying and collapse stopped conditions. This is a fixed concept of prevention. However, we must maintain a balance and a lot of hungry lubrication between excessive lubrication.
Traditionally, the lubrication plan is based on the time given. Equipment suppliers often lubricated plan to develop according to the operating time. And equipment suppliers are often added to the guidance on the amount of lubricating oil in their service planning process.
