Maintenance of non-standard bearing lubrication methods and how to detect running after installation?

Maintenance of non-standard bearing lubrication methods and how to detect running after installation? Source: bearing | last updated: - 2020 09 - 09 introduction to maintenance of non-standard bearing lubrication way according to the area of use and conditions of use and environmental conditions choose size, precision, with appropriate non-standard bearings is the prerequisite of bearing life and reliability. Use parts: non-standard bearing is suitable for predominantly radial load under the combination of radial and axial load, usually with two sets of non-standard bearing pair is used, should be mainly in car wheel hub, before and after active transmission parts, such as bevel gear, differential, reducer. Allows speed: under the correct installation, lubrication good environment, allowing for bearing limit speed of 0. 3 - 0. 5 times. Generally under normal circumstances, with 0. 2 times the limit speed for the most appropriate. Allows tilt Angle: non-standard bearings generally are not allowed to have tilted axis relative to the shell hole, if there are any tilt, no more than 2 'biggest. Allow temperature: under normal load, and lubricant has a high temperature resistant performance, and abundant lubrication conditions, general bearing in - are allowed 30℃- Work under the temperature 150 ℃. Non-standard bearing lubrication how to detect the power operation after installation, bearing temperature after the installation, in order to check whether the installation is correct, check for running. Small mechanical can rotate with the hand, to confirm whether to rotate smoothly. Check project has caused by foreign bodies, scars, creasing seized up, due to bad installation, installation of seat processing bad moment is not stable, because the clearance is too small, installation error, seal friction caused by the torque is too big, and so on. If there is no abnormal can start power operation. Dynamic operation, from the beginning of the no-load speed, slowly up to the rated operating conditions. Test run to check the items, whether there is abnormal sound, non-standard bearing temperature change, lubricant leakage or discoloration, and so on. If discovery is unusual, should immediately stop, check machine, when it is necessary to remove the bearing inspection. Bearing temperature, average according to the external temperature of the bearing. But using the oil hole directly measuring the temperature of the bearing outer ring more accurate. Rolling bearing temperature, from the beginning of the work gradually rise, usually 1 ~ 2 hours after the temperature stability. If the bearing installation, the temperature will rise sharply, abnormal high temperature. The reason such as lubricant, non-standard bearing clearance is too small, too much bad installation, sealing device too much friction, etc. Non-standard bearing examination such as the rotation of the sound with a stethoscope, a strong metal noise, such as vision, irregular note that exception. Its reason has poor lubrication, shaft or precision bearing, bearing damage, foreign body intrusion, etc.
