When the TIMKEN bearing equipment is regularly inspected, operated, and the bearings removed during the replacement of the peripheral parts are stopped, it is necessary to determine whether the secondary bearing parts can be reused and the operation status is better or worse. In order to clarify and check the remaining amount of the visited lubricant, the bearing should be cleaned well after sampling.
a. The inner and outer rings, the rolling elements, and any one of the trusses are cracked and fragmented.
b. Any one of the inner and outer rings and the rolling elements are peeled off.
c. The raceway surface, the ribs, and the rolling elements have significant jamming.
d. The truss is severely worn or the rivets are loose and fierce.
e. The raceway surface, rolling elements are rusted and flawed.
f. There are significant indentations and marks on the rolling surface and the rolling elements.
g. There is creep on the inner diameter surface of the inner ring or the outer diameter of the outer ring.
h. Superheated and discolored.
i. Grease seal bearing seals and dust cover damage are serious.
When using TIMKEN bearings, sometimes we can hear the noise of the bearings. In fact, in theory, the bearings themselves will not produce noise, and the noise we hear is the direct or indirect bearing and surrounding structure. Vibration sound effect. So why does the bearing vibrate? Today, let me explain it briefly for everyone, please read it carefully!
When the number of loading rolling bodies changes, the excitation will occur. When a radial load is applied to an imported bearing, the number of rolling elements that carry the load will change during operation, which causes the load direction to shift. . The resulting vibration is unavoidable, but the current bearing vibration and noise seem to be reduced. Why? This is because the current TIMKEN bearings are designed to be preloaded to reduce and load on all rolling elements, reducing vibration and reducing noise. Although it is preloaded, it does not completely relieve vibration and noise. So how do you further reduce the noise?
1. Prevent excitation vibration between the excitation component and the resonance component.
2. Change the stiffness to achieve the purpose of changing the critical frequency.
3. Remove the critical excitation vibration.
