Analysis of correct maintenance method of IKO bearing
Cleaning: when the IKO bearing is disassembled for inspection, the appearance record shall be made by photography and other methods. In addition, confirm the amount of remaining lubricant and sample the lubricant before cleaning the maintenance method of IKO bearing.
The cleaning maintenance method of IKO bearing is divided into rough cleaning and fine cleaning, and the metal mesh frame can be placed at the bottom of the used container.
During rough cleaning, use a brush to remove grease or adhesion in the oil. At this time, if the IKO bearing is rotated in the oil, pay attention to damage the rolling surface due to foreign matters.
During the fine cleaning, the maintenance method of IKO bearing shall be slowly rotated in the oil, which shall be carefully carried out.
The commonly used cleaning agent is neutral water-free diesel oil or kerosene, and sometimes warm alkaline solution is used as required. No matter what kind of cleaning agent is used, always filter and keep clean. After cleaning, apply anti rust oil or anti rust grease on IKO bearing immediately.
In order to judge whether the removed maintenance method of IKO bearing can be reused, the dimensional accuracy, rotation accuracy, internal clearance, mating surface, raceway surface, cage and sealing ring shall be emphatically checked.
The judgment criteria vary according to the mechanical performance, importance and inspection cycle. In case of the following damage, IKO bearing shall not be reused and must be replaced.
Fracture and defect of IKO bearing parts.
Peeling of the rolling surface of the raceway surface.
Maintenance method of IKO bearing
Rolling bearing precision parts have high dimensional precision. If they are not installed properly, they will lose their precision and performance, and even cause bearing failure in serious cases. The bearing installation site and installation tools must be clean to prevent various particles from inside maintenance method of IKO bearing. The bearing may be easily damaged during operation. When installing and disassembling the bearing, the hammer shall not be directly hammered, but uniform pressure shall be applied. When the interference between the shaft and the bearing is large, the bearing shall be installed immediately after heating.
In order to prevent the bearing from rusting during transportation or storage under various environmental conditions, rust prevention treatment must be carried out. According to the national GB / ts597 standard. The antirust period of the maintenance method of IKO bearing is half a year.
Products are easily damaged by environmental conditions such as snow, dust, temperature and corrosive substances during these circulation processes. Therefore, it is required that the packaging of the maintenance method of IKO bearing should have multi clock performance, such as anti-corrosion, moisture-proof, shock proof, anti-collision, pressure resistance, etc.
There shall be no rain leakage in the warehouse, the bearing shall be stored in a place away from direct sunlight, and the indoor air shall be ventilated, but there shall be no dust invasion. Ventilation equipment and temperature regulating equipment shall be set in the warehouse. The warehouse shall be kept dry, the relative temperature shall be controlled below 80%, the indoor temperature shall be controlled at about 25 ° C, and there shall be no large temperature change in day and night.
If the temperature is too low, the maintenance method of IKO bearing is easy to crystallize and crack, resulting in the corrosion of some metals exposed. If the temperature is too high, the rust releasing agent is easy to be lost (evaporated) or deteriorated. If the temperature difference between day and night is large, it is easy to cause moisture to condense on the bearing surface and cause corrosion. In winter, the bearing should not be stored near the heating.
The ground in the warehouse shall be hard and not easy to dust. The bearing shall not be stored in the same warehouse with corrosive materials such as acid, alkali and salt, chemical raw materials and materials with large moisture content. When storing bearings, it is not easy to be disturbed by harmful gases around the warehouse.
