Analysis of self-aligning ball bearings installed before the six major preparation projects
First, before IKO bearings are installed, ball bearings the appropriate measuring tools should be used to specify the machining quality (such as dimensional accuracy, shape accuracy and surface roughness, etc.) of the shaft and seat and related parts as specified in the design drawings.
Second, the presence of bumps, burrs, rust or solid particles (such as debris, sand, soil) on the mounting surface of the shaft and bearing housing holes will not only make the self-aligning ball bearing difficult to install and make the installation position incorrect , And solid particles such as falling into the IKO bearing will play the role of grinding, when the self-aligning ball bearings will be worn or scratched when the IKO bearing the surface of the bearing, so the installation must be carefully checked before, such as the above defects , ball bearings Should be amended. For example, the use of oil to remove burrs, bumps, rust, and fine sand cloth to light, such as cleaning solid particles, dirt and so on.
Third, the assembly surface should be clean with gasoline, kerosene, toluene or xylene and other solutions clean and clean with a clean cloth, and then coated with a thin layer of oil, so that the installation operation can be more convenient.
Fourth, the temporary installation of self-aligning ball bearing package, it is immersed in the gasoline and other liquids in the hand gently rotation, ball bearings to ensure that the cage, rolling body and the roller surface of the packaging oil thoroughly cleaned.
Fifth, the cleaning of a large number of IKO bearings, the first temperature of 90 ~ 100 ℃ hot oil oil hot to make the package of oil melting, while the use of seamless and do not fall off the tools to dig all the old oil, and then blush for a few minutes, ball bearings And then rinse with kerosene oil, and finally washed with gasoline again. After cleaning and cleaning, wear gloves on the self-aligning ball bearings on the table clean cloth or paper to dry.
Sixth, note with IKO bearings sealed with this method can not be cleaned, sealed inside should be kept as clean.
