Detection of bearing should pay attention to six issues, 1 rotation of the circle and carefully washing holder, at the junction of the rolling elements and raceways, require any hidden parts of the original residual oil washed out. The bearing should be attached in the dry cleaning oil spray cleaning, put the table with a clean paper in neutral lining on the dry, or slowly in the far-infrared oven drying. Self cleaning oil spray after drying or drying, the whole process may turn the bearing rings, rolling elements or any stick. The rolling bearings can be removed from their oil seals before they are delivered for routine inspection and immersed in a washing gasoline or acid free kerosene containing 3% oil.
2. The lubricating oil shall be dripped into accordance with the provisions and delivered immediately for inspection of bearings that have been dried or dried. No oil film bearing outer surface protection at this time, the entire inspection process shall not directly touch the hand skin, the operator should wear clean gloves, or hand coated with anti rust agent, but must avoid the appearance of rust on the rolling bearing with, otherwise it will make the measurement results deviation.
3, should be delivered immediately or use rust prevention inventory management, the entire inspection process should also pay attention to the completion of the bearing after the inspection is completed. In case it takes too long to cause rust. Note that the use of pure gasoline without oil cleaning will also cause corrosion.
4, the bearing has dry or drying, shall be lubricated and immediate delivery inspection, no oil film bearing at the outer surface of the protection, in the whole course of the examination shall not directly touch the hand skin, the operator should wear clean gloves, or hand coated with anti rust agent, but must avoid rolling surface rust hand with bearing, otherwise it will make the measurement results deviation.
5, bearings in the inspection should be delivered immediately after the use or rust prevention inventory management, the entire inspection process should also pay attention to completion, so as not to last too long, causing corrosion. Note that the use of pure gasoline without oil cleaning will also cause corrosion.
A metal plate used in the prior examination and inspection, also some 6 bearing gauge, standard parts and measuring instruments placed together in checking the place on which can quickly make the homogenization temperature and room temperature of the objects. |
