When the TIMKEN bearing equipment is regularly inspected, worked, and the parts that are removed during the conversion of the external parts are interrupted, it is necessary to sequentially distinguish whether the secondary bearing parts can be reused and the application conditions are better or worse. Query the remaining amount of access to the lubricant; sample it backwards; remove the bearing well.
1. There are cracks and fragments in the inner and outer rings, the rolling body, and the holding frame.
2. Any one of the inner and outer rings and the rolling body is stripped.
3. The raceway surface, the ribs and the rolling body have obvious card injuries.
4. The wear of the frame is severe or the rivet is loose and fierce.
5. The raceway surface, the rolling body is rusty and flawed.
6. There are obvious indentations and marks on the rolling surface and the rolling body.
7. There is creep on the inner diameter surface of the inner ring or the outer diameter of the outer ring.
8, overheating and discoloration.
9. The sealing ring and dust cover of the grease sealed bearing are severely damaged.
In the use of TIMKEN bearings; sometimes we can hear the noise of the bearing; in fact; in theory; the bearing itself does not produce noise; and the noise we hear is the bearing directly or directly with the surrounding layout Oscillation sound effect. So; why does the bearing oscillate?
When the number of loaded tumblers is changed; the excitation that occurs when a radial load is applied to an imported bearing; the number of tumblers that carry the load will change during operation; this causes a shift in the load direction. The resulting oscillations are inevitable; however; today's bearing oscillations and noise are reduced as much; why? Because today's TIMKEN bearings are selected for preloading to reduce; loading on all rolling bodies; then reducing the oscillation; also reducing the noise. Although the preload is selected; however; the oscillation and noise are not completely eliminated. Confusion. So; how to further reduce the noise?
1. Block the encouraging oscillation between the agitating component and the resonant component.
2, change the stiffness; and reach the intention to change the critical frequency.
3. Remove the critical encouragement oscillation.
