(1) Scars acoustic control method
Rolling bearing rolling surface if cracks, indentation, or corrosion occurs as riveting rivets as periodic vibration and noise, the cycle may be fixed mostly related to speed into a certain relationship to the injuries occurred in succession on the channel, the scars on the ball hidden now, but this noise there are some changes with the installation and lubrication conditions.
The type of noise control methods are: installation can not tap the bearing, the bearing and shaft assembly and then into the bearing to prevent bearing mounted oblique; inventory to prevent bearing corrosion and transport to prevent shock and vibration; the use of high viscosity grease.
(2) Dust acoustic control methods
Dust and other foreign matter within the Rolling occur periodic vibration and the so-called dust acoustic, vibration and noise size uncertain, and with or without.
Dust acoustic control methods: the cleaning methods to improve the bearing, installation bearing, shaft, bore and match all the parts clear the lubricant within the foreign body; to improve the bearing seal; avoid the use of materials, impure or embedded foreign body in the plastic cage.
(3) Lubrication caused by noise and its countermeasures
Lubricant selection error, lubricants, or aging indurations can lead to bearing vibration and noise, and this noise does not have certain regularity. In this case, only the selection of a suitable lubricant, and adjust their amount of lubricant to extend the life of the lubricant and to reasonably determine the replacement cycle.
Host-related noise and its countermeasures
This noise is not simply caused by the bearing, thus the single from the bearing to find the cause is futile, response to host full attention, if necessary, to improve the performance of the host.
