After the IKO bearing equipment is completed; in order to check whether the equipment is correct; to check the work. The small machine can be rotated by hand; to recognize whether the rotation can be smooth. Check the project for the work caused by foreign objects, scratches and indentations; Poor equipment; the torque generated by the equipment seat is not stable; the torque is too large due to too small clearance, equipment error, seal conflict, etc. If there is no abnormality, the power can be started.
Large machinery can't be rotated manually; therefore, the power is blocked immediately after the no-load start; the machine is idling; check whether there is oscillation, noise, whether the rotating parts can touch, etc.; after acknowledging that there is no abnormality; enter the power work.
Power work; starting from no-load low-speed; slowly progressing to additional work for the specified conditions. Check the items in the test work; can there be abnormal sound, IKO bearing temperature change, smoothing agent leakage or discoloration, etc. If found Abnormal; should work intermittently; view the machinery; if necessary, remove the bearing to view.
IKO bearing temperature; generally can be estimated according to the external temperature of the bearing housing. But the oil hole directly measures the temperature of the outer ring of the bearing more accurately. The bearing temperature; gradually rises from the beginning of the work; generally the temperature is stable after 1~2 hours. If the bearing Poor equipment; temperature will rise sharply; abnormal high temperature occurs. The reasons are such as excessive smoothing agent, too small bearing clearance, poor equipment, excessive conflict of sealing equipment, etc. High-speed rotation; IKO bearing layout, smooth method selection fault Etc. is also the reason.
The transition sound of IKO bearing is viewed with a stethoscope, etc.; there are strong metal noise, abnormal sounds, irregular sounds, etc. to clarify the abnormality. The reason is poor smoothness, poor accuracy of shaft or bearing housing, bearing damage, foreign matter intrusion, etc.
