INA bearing inspection after the installation of the matters needing attention

Lubrication is very important, not only for bearing, also for all of INA bearings. But please note that the bearing should not add too much grease. And then replace the slide bearing lubricant. Use after xie used engine oil, engine oil lubrication bearing if possible, should be impregnated with fresh oil and let the machine in low speed rotation for a few minutes. As far as possible make the oil collecting residual pollutants, and then purging in addition to the oil. And the use of grease lubrication bearing in replacing grease, used by Joe in addition to the editor should avoid contact with cotton to any part of the spherical bearing. Because these residues fiber may wedged in between the scroll and damage, especially the application of small bearing more need to pay attention to this problem. Contact fatigue failure refers to the INA bearing working surface under the role of alternating stress and failure. Contact fatigue spalling occurred in sliding bearing working surface, often accompanied by fatigue crack, first of all, from the maximum cyclic shear stress under contact surface, and then extended to form a different flake shape, such as dot to pitting corrosion or pitting spalling, peel into small sheet according to the shallow flaking. In order to verify that the bearings have been assembled correctly, perform the test. 1. First of all, the axis of rotation or shell, to see if it detects something unusual. 2. Then, start to be applied load sliding bearing of the computer. Under the condition of low speed rotation in observation, gradually increase the speed and load, at the same time to stop any noise, vibration and temperature. 3. If there is anything unusual is found in the process of operation, stop the computer and perform the inspection. Review of unusual noise or noise levels should be produced by others properly installed and INA bearings under the condition of normal operation of sound familiar work. Check the INA bearing, don't let bearing exposure to pollutants or moisture environment. If the job is interrupted, should with oil film, paper or similar material by machine. If don't have to remove and may perform inspection of cleaning without masking of sliding bearing, for coating with brush with petroleum solvent cleaning, then dry with a lint-free cloth or with compressed air to blow dry, Be careful not to let the bearing component starting rotation) 。 With a little mirror, and the probe used in the similar to the dentist to check the bearing of the orbit plane, retainer and beads. Do not clean the encrypted block or dust bearing; You just wipe the outer surface. If the bearing is need to replace damaged situation. In regular maintenance downtime period change bearing is far better than the bearing damage of selected into a sudden stop loss is much more economical.
