1. The small machine can be rotated by hand; to admit whether it can rotate smoothly. Check that the project has poor work due to foreign matter, scars and indentation; the equipment is not stable due to poor equipment; If the gap is too small, the equipment is wrong, the seal conflicts, the torque is too large, etc. If there is no abnormality, the power can be started. The large machinery can't be rotated manually; therefore, the power is blocked immediately after the no-load start; the machine is idling; Whether noise, rotating parts can touch, etc.; admit that there is no abnormality; enter power work. Power work; start from no-load low-speed; slowly progress to additional work of the specified conditions. Abnormal sound, KOYO bearing temperature change, smoothing agent leakage or discoloration, etc. If it is found abnormal; should work intermittently; view the machine; if necessary, remove the bearing to view.
2, bearing temperature; generally can be estimated based on the external temperature of the bearing seat. But the oil hole directly measured KOYO bearing outer ring temperature is more accurate. Bearing temperature; gradually increase from the beginning of the work; generally 1~2 hours after the temperature is stable. If the bearing equipment is bad; the temperature will rise sharply; the abnormal high temperature will occur. The reasons are such as excessive smoothing agent, too small bearing clearance, poor equipment, excessive conflict of sealing equipment, etc. High-speed rotating occasion; selection of bearing layout and smoothing method Faults are also the reason. The transition sound of the 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 the shaft or bearing housing, bearing damage, foreign matter intrusion. Wait.
3. The reasons for the effectiveness of the bearing are taken from the two aspects of the application reason and the connotation factor; the application factor mainly depends on whether our application method can be reasonable; the connotation element is actually the level problem when we select KOYO bearing.
The application elements mainly refer to whether equipment adjustment, application protection, protection repair, etc. can meet the skill requirements. Equipment conditions are one of the primary factors in the application of factors; bearings often cause forces on the entire set of bearings due to improper equipment. Change; the bearing works under abnormal conditions and fails prematurely. According to the skill requirements of bearing equipment, operation, protection and protection; the load, speed, working temperature, oscillation, noise and smooth conditions accepted by the bearing in operation Monitor and view; find abnormalities and find the cause immediately; make adjustments; make them recover normally. In addition; it is also important to analyze the quality of smooth grease and surrounding medium and atmosphere.
Adhere to the hygiene of KOYO bearings and their surroundings, even small dust that is invisible to the naked eye; it will also have adverse effects on the bearings. Therefore, it is necessary to adhere to the surrounding hygiene; so that the dust will not invade the bearings.
Use it carefully.
In the application of the bearing impact; there will be scars or indentations; induced incidents. Severe; will lead to cracks, cracking; it is necessary to pay attention.
Use special tools for bearings.
It is necessary to use special tools;
Prevent the bearing from rusting.
When operating KOYO bearings; hand sweat will form rust. Pay attention to use clean hands; try to bring gloves; pay attention to corrosive gases.
