IKO Spherical roller bearings after installation, in order to check the installation is correct, the operation check. Small mechanical hand rotation, to determine whether the rotation smooth. Inspection items nick, indentation caused by dysfunctional torque instability, arising due to poor installation, mount processing bad due to the clearance is too small, installation errors, and seal friction torque and so on. If there is no exception, you can start the power operation.
Large machinery can not be manually rotated so cut off the power immediately after the no-load start, idle machinery, check for vibration, noise, rotating parts in contact to confirm that no abnormality, the power operation. Power operation, start from no-load low-speed, slowly increased to the conditions stipulated in the rated operation. Test run to check the matters, whether there is abnormal sound, temperature changes, lubricant leakage or discoloration. If abnormal, should be immediately discontinued operation, check the mechanical, if necessary, to remove the IKO Spherical roller bearings check.
Temperature can be speculated that under the external temperature of the bearing. However, direct measurement of the outer ring of the use of hole temperature is more accurate. The operation began gradually increased, usually 1 to 2 hours after temperature stabilization. Poor installation, the temperature will soar, and abnormal high temperature. The reason lubricant such as excessive clearance is too small, poor installation, and sealing devices friction is too large. High-speed rotation of the occasion, structure and lubricating the way the wrong choice of the reasons.
Rotation with a stethoscope and other examination, strong metal noise, abnormal sound, irregular, the sound of exception. The reason for poor lubrication, poor shaft or bearing accuracy, bearing damage, dust and debris.
