nsk operation and peripheral parts change
2015-11-09 by zysbearing
Nsk bearings in use, sometimes we can hear in fact, theoretically, the bearing itself does not produce noise, and the noise we heard was bearing directly or indirectly arising from the surrounding structure vibrating sound effect. So, why would the fatigue testing machine bearing vibration it? Today, it is for me to explain something simple for everyone, please read carefully!
When changes in the number of rolling loads, will produce excitation when a radial load on a load of imported bearings, its load bearing rolling element number will be some changes in the operation, which caused the load shift direction . The resulting vibration is inevitable, however, now seems to have a bearing vibration and noise are reduced, which is why? Nsk bearings due to the current use of the design to reduce the pre-load, rolling load at all, thereby reducing vibration, but also reduces the noise. Although the use of the pre-loaded, but can not completely relieve the vibration and noise problems. So, how to further reduce the noise it?
nsk operation and peripheral parts change when the suspension is removed check the bearings, the demand in turn determine whether the second bearing parts can be re-applied and recorded using the good in bad condition. In order to understand and query visit remaining amount of lubricant, the sample back to a good wash bearings.
a. inner and outer rings, rolling elements, any of a confrontation between Hydrodynamic Bearing the two frame cracks and rendering debris.
