Use Of Tapered Roller Bearings
Although the quality of tapered roller bearing is good, but the rolling bearing is a precision part, its use must be carefully carried out accordingly. No matter how high-performance the bearings, if used improperly, will not get the expected high performance.
Attention to the use of bearings are as follows: (1), keep tapered roller bearings and surrounding cleaning. Even small dust, which is invisible to the eye, can have a bad effect on the bearing. So, keep the surrounding clean so that the dust does not invade the bearing. (2), use carefully. In the use of a strong impact of tapered roller bearings, will produce scars and indentation, the cause of the accident. Serious case, will crack, break, so must notice. (3), the use of appropriate operation tools. Avoid replacing with existing tools, and you must use the right tools. (4), should pay attention to the rust of tapered roller bearing. When the bearing is operated, the sweat on the hand becomes the cause of the rust.
Pay attention to clean hands operation, preferably with gloves. Tapered roller Bearings The use of hearing to identify irregular operation is a very common method, examples such as the use of electronic stethoscope to find that 10 of abnormal noise is experienced operators. If a bearing is in good working condition, it emits a low whine sound, if a sharp hissing tapered roller bearing, creak and other irregular sound, usually indicates that the bearing is in bad condition. 1, Tile surface corrosion: The concentration anomaly of nonferrous metals was found in the spectral analysis, and there were many submicron grade wear particles in the iron spectrum, such as excessive water content and acid value. 2, the axle neck surface pulls the wound: The iron spectrum has the iron to cut the abrasive grain or the black oxide particle, the metal surface has the tempering color. 3, the surface corrosion of the axle neck: The spectral analysis found that iron element concentration anomaly, iron spectrum has many submicron particles of iron, lubricating oil water or acid value exceeded. 4, Surface tensile injury: Iron Spectrum found in the cutting abrasive grains, abrasive components of non-ferrous metals. 5, the back fretting wear: The spectral analysis found abnormal iron concentration, iron spectrum has many submicron wear particles, lubricating oil moisture and acid value anomalies. Under the condition of liquid lubrication, the sliding surface is separated from the lubricating oil without direct contact, but also can greatly reduce the friction loss and surface wear, oil film also has a certain vibration-absorbing ability of sharp creak noise may be due to improper lubrication caused. Improper bearing clearance can also cause metal sound. Tapered roller bearings in the outer ring of the track will cause vibration, and the smooth and crisp sound, if the installation of the percussion caused by the damage will also produce noise, this noise will vary with the speed of the bearing. If there is intermittent noise, it means that the rolling piece may be damaged, tapered roller bearings This sound occurs when the damaged surface is rolling out of date, the bearings in the case of contamination often cause hissing sound, serious bearing damage will produce irregular and huge noise.
