After installation of the the IKO thrust ball bearings, 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, bearing temperature changes, lubricant leakage or discoloration. If abnormal, should be immediately discontinued operation, check the mechanical, if necessary, to remove the bearing check.
IKO thrust ball bearing temperature, and can be speculated that the external temperature of the bearing. However, the use of hole directly measuring the temperature of the bearing outer ring is more accurate. Bearing temperature gradually increased from the operation, usually 1 to 2 hours after temperature stabilization. If the bearing is bad installation, the temperature will soar, and abnormal high temperature. The reason lubricant such as excessive bearing clearance is too small, poor installation, and sealing devices friction is too large. Occasions of high-speed rotation, the bearing structure, the lubrication mode select error is also the reason.
Turn the sound with a stethoscope and other tests have strong metal noise, abnormal sound, irregular sound the IKO thrust ball bearings explain anomalies. The reason for poor lubrication, poor shaft or bearing accuracy, bearing damage, dust and debris.
Do not let the check bearing bearings exposed to the environment of contaminants or moisture. If the interruption of work should be based on the greaseproof paper of plastic sheeting or similar material to cover once the machine. Cleaning the exposed bearings without disassembling the case may perform a check, coated with a petroleum solvent cleaning to coating with the brush, then dry with a lint cloth or compressed air (be careful not to bearing assemblies starting rotation). Kind of probe used by a small mirror and similar dentist to check the track surface of the bearing retainer and beads. Not cleaning encryption cover or dust bearing; wipe the external surface can be. If the bearing was damage to the circumstances that need replacing. Replacement of bearing much more economical due to the array bearing damage selected as the sudden stop loss in the regular shutdown maintenance period.
The lubricant is very important not only for bearings, iko thrust ball bearings. Note, however, the Japanese bearings should not add too much grease. Then is to replace the bearing lubricant. The use of oil lubricated bearings diarrhea in addition to the old oil, if you can, it should be re-poured fresh oil and the machine a few minutes at low speed rotation. As much as possible so that the oil to the collection of residual contaminants, and then diarrhea among these oil. The use of grease lubricated bearings in the replacement of grease used Joe in addition to the device should be avoided with a cotton material come into contact with any part of the bearing. Because these residual fibers may be wedged in between the rolling elements and cause damage, especially bearing applications should pay more attention to this problem.
Is not only bad iko thrust ball bearings, the surface quality and workpiece resistance to intergranular corrosion decreased. When iko thrust ball bearings workpiece serious overheating of coarse grains, but also ferritic steel increased, and could easily lead to the deterioration of the workpiece thermal processing performance. lcrl8Ni9Ti stainless steel to accompany the body or flange when overheating, easy to produce orange peel-like surface defects.
