Second, when using the device, you must carefully and forcefully not allow strong punching; do not use the hammer; directly tap the FAG bearing; do not allow the pressure to pass through the rolling body.
Third, use appropriate and precise equipment to try to use special things; try to prevent the use of cloth and short fibers and the like.
Fourth, to prevent the corrosion of FAG bearings directly when taking the bearings by hand; to wash away the sweat on the hands; and apply high-quality mineral oil before operation; especially in the dry season and summer to pay attention to rust. However; Under special operating conditions; the bearing can obtain a better life than the traditional accounting; especially in the case of light loads. These special operating conditions are; when the rolling surface (track and roll) is effectively separated by a smooth oil film And constrained pollutants can be caused by external damage. In fact; under ambition; the so-called Eternal FAG bearing life is able.
According to the application site, operating conditions and environmental conditions, the standard scale and accuracy are selected. The suitable bearing is the condition for ensuring the bearing life and feasibility.
The industrial design of the top and bearing is reasonable and perfect, and it has a world-class level. The strong quality ensures the life of the bearing. Bearing casting has to undergo careful process such as casting, bearing heat treatment, turning, grinding and bearing equipment; The processing life of the bearing will be affected by various processing steps. In the meantime, it affects the quality of the imported bearing; it is directly related to the bearing failure. With the continuous improvement of the technology detection, FAG bearing appearance inspection found that the grinding process of the enamel layer is fish. FAG bearing appearance is closely related to the second, 2FAG bearing used in the production of metal lottery; once was a primary factor affecting bearing failure; now with the continuous advancement of metallurgical skills; the original data extraction has been improved; The quality has also been greatly promoted; today's original data quality elements have been significantly reduced in the bearing failure; at this stage, the problem still exists.
Third, whether the selection of bearing production is qualified or a factor of bearing failure must be considered; in the detection of general bearing failure, it is based on a lot of Beijing data; data analysis; failure environment; casting process; The primary element; and deal with it; facilitate the continuous optimization of the bearing; the use of the number of life; and the progress of efficiency. The service life of the extended bearing; prevent the sudden early failure of the bearing attack. The device condition is one of the primary elements of the application factor. FAG bearings often cause changes in the force condition between the various FAG bearing parts due to the unsuitable device; the bearing works under abnormal conditions and fails in advance. According to the bearing device; application; protection; protection skills demand; The load accepted by the bearing in operation; the speed; the operating temperature; the oscillation; the noise and the smooth condition are monitored and viewed; the abnormality is immediately found; the adjustment is made; the rehabilitation is normal.
But not all machines are equipped with this leading equipment. In this case, it is necessary for the machine operator or repair engineer to adhere to the FAG bearing fault signal.
The smooth and loud sound of the work; the sharp noise can be caused by the lack of smoothness of the bearing gap and the formation of metal sound. The dent on the outer ring track of the FAG bearing will cause oscillation. As for the device that strikes the flaw There will be noise; this kind of noise bearing has different speed grades. If there is intermittent noise; then some of the tumbling; it can be damaged; this sound is presented; when the appearance is damaged, the date of the launch; if it is the sound of the bearing 嘶嘶Pollution often forms a severely hazardous FAG bearing; and creates irregular large noise.
However, it is generally unnecessary to replace the FAG bearing at this time. Therefore, the bearing is damaged; of course, it can also be heard through listening. For example, using a better method; such as electronic safety monitoring equipment; operation before bearing injection.
