The preparatory work of the bearing routine inspection is completed in 6 steps
1. rotation of the outer ring and cage, carefully washed 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 bearing can be removed from the oil seal before delivery of the Convention and immerse it in the washing gasoline or the acid free kerosene containing 3% oil.
2. the oil should be dripped into the lubricating oil and delivered immediately to the 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 immediately delivered or used for antirust inventory treatment, and the whole inspection process should be completed and the bearings are finished after inspection. In order to avoid corrosion over a long period of time. The use of pure gasoline without oil can also cause rust.
Bearing 4. 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., after the inspection is completed, the bearing shall be delivered immediately or the rust proof stock shall be disposed. The whole inspection process shall also be closely completed, so as not to cause corrosion for a long time. The use of pure gasoline without oil can also cause rust.
A metal plate used in the inspection and check before 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.
Obviously, only the above preparation work is done strictly in order to ensure the accuracy of the inspection, and the bearing is not corroded during the whole inspection process.
