Main Points Analysis Of Oil Lubrication And Grease Lubrication For Maintaining FAG One-Way Bearing

wallpapers Environment 2020-11-19
The lubrication process is indispensable during the use of FAG one-way bearings. However, there are many lubrication methods. The problems that should be paid attention to in the lubrication process of various lubrication methods are also different, which leads to users’ Confused, here is what are the precautions for FAG bearing oil lubrication and grease.
1. Grease lubrication
The relubrication of FAG bearings is carried out during the planned equipment shutdown period and is regularly replenished. At the same time, the old grease is removed or the old grease is squeezed out through the drain. The grease nozzle should be wiped clean before adding fresh grease. If the one-way bearing box does not have an oil filling nozzle, the bearing box cover or end cover should be opened to take out the old grease. After cleaning, add fresh grease of the same model.
2. Lubricating oil
Regularly check the oil level and quality of the lubricating oil. In general, the normal oil level should be within the range of 1/3-2/3 of the equipment oil level window or mark. The oil replenishment method is an oil cup, and the displayed oil level only represents the oil replenishment capacity, while the oil level of the FAG bearing box meets the operating requirements. The oil level in the oil cup is less than 1/4 of its total volume.
Inspection and replenishment methods, take out a small amount of lubricating oil as a sample and compare it with fresh lubricating oil. Capable units may consider conducting an oil quality test to ensure that the oil quality is qualified. If the sample looks like a cloud, it may be the result of mixing with water, which is what we often call oil emulsification, and the lubricant should be replaced at this time.
If the sample path becomes darker or thicker, it may indicate that the lubricating oil has begun to be carbonized, and the old lubricating oil should be completely replaced. If possible, flush the oil circuit with fresh lubricant. When replacing the lubricating oil, make sure that the new and old models of the replaced lubricating oil are the same, and add the required oil level.
The grease used in the one-way bearing must have an anti-rust effect, and the anti-rust agent should preferably be insoluble in water. Grease should have good adhesion to form an oil film on the surface of the steel, which can be maintained even if the grease is filled with water. Grease will soften during machining, causing leakage. When there is an application example of vibration, grease will be thrown into the bearing from the FAG bearing seat.
