1, IKO bearing cleaning
When removing the IKO bearing for inspection, first record the appearance of the bearing, confirm the residual amount of the moisturizer, and then wash the bearing after sampling and checking the moisturizer. As a cleaning agent, gasoline and kerosene are commonly used.
The cleaning of the removed bearing is divided into coarse cleaning and fine fine washing. In the container, the metal mesh bottom is placed first, so that the IKO bearing does not directly contact the container. During rough cleaning, if the bearing is rotated with dirt, it will damage the IKO bearing rolling surface and should be noted. In the rough cleaning oil, use a brush to remove the moisturizing grease and sticks. After it is almost clean, transfer it to a fine wash.
Fine washing is to carefully clean the IKO bearing while rotating it in the cleaning oil. In addition, the cleaning oil should always be kept clean.
2. Overhaul of IKO bearings
In order to judge whether the removed IKO bearing can be reused, check the bearing after cleaning, carefully check the raceway surface, the rolling surface, the state of the mating surface, the wear of the cage, the increase of IKO bearing clearance and whether there is any Damage and abnormality with reduced dimensional accuracy. For non-separable ball bearings, use one hand to support the inner ring and rotate the outer ring to check if it is smooth.
1, oil bath moisturizing
Oil bath moisturizing is the most common moisturizing method in IKO
bearings, suitable for moisturizing low and medium speed bearings. Part of the bearing is immersed in the groove, the moisturizing oil is brought up by the rotating bearing parts, and then flows back to the oil groove. The oil level should be slightly lower than the center of the lowest rolling element.
2, dripping oil moisturizing
Drip oil moisturizing is suitable for bearing parts that need to supply moisturizing oil quantitatively. The amount of dripping oil is generally one drop per 3-8 seconds. Excessive oil quantity will cause the bearing temperature to increase.
3, circulating oil moisturizing
The filtered oil is transferred to the IKO bearing component by an oil pump, filtered and cooled by the moisturizing oil after the bearing. Since the circulating oil can take a certain amount of heat to cool the bearing, this method is suitable for bearing parts with higher rotational speed.
4, spray moisturizing
The dry compressed air is mixed with the moisturizing oil through a sprayer to form an oil mist. The IKO bearing is sprayed, and the air flow can effectively cool the bearing and prevent the intrusion of impurities. This method is suitable for the moisturization of high-speed, high-temperature bearing components.
5, spray moisturizing
The high-pressure oil is injected into the bearing through the nozzle by the oil pump, and the oil injected into the IKO bearing flows into the oil groove through the other end of the bearing. When the bearing rotates at a high speed, the rolling elements and the cage also form a flow of air around the air at a relatively high rotational speed. It is difficult to send the moisturizing oil to the IKO bearing by the general moisturizing method. At this time, the moisturizing oil must be sprayed by high pressure. Spray into the bearing and the position of the nozzle should be between the inner ring and the center of the cage!
