On the FAG bearing vibration to deal with

In general, as without excitation FAG bearings the world's top bearing the, but if there is a vibration, there must be a good check, because the operation or installation error, a small part of the bearing raceways and rolling elements may be damaged. In the operation, rolling across the damaged bearing components will produce a specific vibration frequency. Vibration frequency analysis can identify the damaged bearing components.
According to the size specifications, accuracy of location and conditions of use and environmental conditions, with the appropriate FAG bearing is the precondition of guaranteeing the bearing life and feasibility.
1, using the site: combined load of tapered roller bearings for radial and axial radial load to bear mainly the, usually bearing two pairs to use, mainly in the automotive front and rear wheels, a driving bevel gear, gear, reducer and other transmission parts.
2, allow the speed: correct installation, lubrication good environment, allowing for 0.3-0.5 times FAG bearing limit speed. Under normal circumstances, the limit of 0.2 times the speed of the most desirable.
3, allow the tilt angle: tapered roller bearings are generally not allowed to tilt axis relative shell hole, if tilt, is less than 2'.
4, allow the temperature: under normal load, and the lubricant has high resistance to high temperature, and the full lubrication conditions, general FAG bearing allows operation at -30 ℃ -150 ℃ temperature environment.
Operation need to check the machine state, the bearing is the focus of attention, and prepare inspection plan thoroughly has become more and more important. Because it is the most important components of rotating machinery condition monitoring, to prevent the FAG bearing damage, to prevent unscheduled repair equipment downtime during early bearing damage caused by the discovery of an important part in the home.
