What are the ways to flush bearings?
The test, can be used to clean the remaining oil scraping feeler, apply the thumb, index finger back and forth slowly rubbing fingers if there is research, the rustling sound, it indicates that the bearing is not clean, should wash again. The bearing in hand, pinch the inner ring, the outer ring (toggle horizontal rotating large bearings can be placed in the assembly stage, the inner pad, the outer ring is suspended, pressing within the circle, rotating outer ring), with flexible rotation, no block, no beating for qualified. After cleaning the bearings, fill in the lubricant, it should be placed on the assembly table, the next pad with a net cloth or paper pad, covered with plastic cloth, pending assembly, not allowed on the ground or box. When moving bearings, it is not allowed to use the hand directly, Dafanb gloves or net cloth should be used to pack the bearings before they are taken. Otherwise, because of the sweat and moisture in the hands, it is easy to cause the bearings to be rusted. On both sides of the bearing with shields or seals, and bearings coated with anti rust, lubrication and oil, because at the time of manufacture have been injected into the grease, so do not wash before installation, for example, 51708ZHS - 12, and - 12 type tractor and redguards Dongfanghong 20 tractor clutch (original code 688808) bearing.
2. shaft and bearing housings, holes and other parts of the cleaning, first with gasoline or kerosene cleaning, dry cloth clean, and then coated with a small amount of oil in order to install. These parts after cleaning, should pay attention to where the casting sand is to completely remove all burrs and sharp edges; bearing parts, must be removed, to avoid residual sand and metal debris when installed into the inner part of the bearing, affecting the quality of assembly. 1., attention to the internal, outer ring separable bearings, do not change the outer ring each other wrong, so as not to affect the quality of contact. On the ball and roller bearings, roller bearings shall be arbitrarily put out in the mix, so as not to affect the accuracy of the installation position. When installing the bearing, in order to easily observe the bearing code number, not to be wrong, the bearing rings should be typed outside and installed. The shell hole 2. bearing and bearing seat heating for a large amount of surplus and large bearing, in order to facilitate the installation, must be installed before heating; for light metal bearing shell hole tight fit (such as aluminum bearing), due to very low hardness, surface to prevent bearing outer ring press bearing shell hole the scratch and galling, should also be heating installation. Heating method, usually bearing or separate bearing ring into the tank with clean oil, so that oil flooded bearings, uniform heating. When the temperature reaches 80 - 90 degrees, remove the heat and install it while the heat is hot. The tank made available 2 3mm thick plate, from the bottom 50 70mm height with a porous plate, bearing in porous plate heating. The aim is to prevent the precipitation of impurities in the oil into the bearings. However, for both bearings with a dust cover or seal ring, the lubricant cannot be heated at the beginning of the installation because of the lubricant used in the manufacture.
