Bearing is an important part of the machinery, machinery, if there is no bearing, it means that people do not have joints, animals without joints, the car does not have the same tire, so our machinery is absolutely no bearings, so we have to think well The use of machinery, we must ensure that machinery bearings can be stable operation, otherwise, machinery is not work. Bearing is broken, the machinery is broken, so our machinery can not make the bearing broken. In case of bad words, then the machine must be timely for bearings, bearing change again, it is best to change the bearings, because the quality of imported bearings made of good quality. We also need to always check the operation of the bearing. After the bearing has been installed, check the operation to check that it is installed correctly. Small machines can be rotated by hand to confirm that they are rotating smoothly. Inspection items due to foreign body, scars, indentation caused by poor operation, due to poor installation, the installation of poor processing due to the uneven rotation torque generated by the clearance is too small, the installation of the error caused by friction and so on a large torque and so on . If there is no abnormality you can start the power running. Because large-scale machinery can not be rotated manually, turn off the power immediately after no-load startup, and perform inertial operation to check for any vibration, noise, contact of rotating parts, etc., and confirm that there is no abnormality and enter the power running. Power operation, starting from no-load low-speed, slowly raised to the rated conditions of operation. Test run during the inspection, whether there is abnormal noise, bearing temperature transfer, lubricant leakage and discoloration and so on. In the test run if found to be abnormal, should immediately stop running, check the machine, if necessary, remove the bearing inspection. Bearing temperature test generally speculate from the shell can be seen. However, the use of oil holes, direct measurement of bearing outer ring temperature, more accurate. Bearing temperature began to run gradually increased, if no exception, usually 1 to 2 hours after the stable. If due to poor bearing or installation, the bearing temperature will rise sharply, abnormal temperature. The reasons such as excessive lubricant, bearing clearance is too small, poor installation, sealing device friction is too large. High-speed rotation of the occasion, the bearing lubrication method selection error is also the reason.
