Self-aligning ball bearing the preparing work before install

Bearing shaft bearing system ( 系统) Both require high rigidity, and require quality ( Mass) As light as possible in order to overcome the contradiction, can take measures such as reducing the surface roughness and improve the surface strengthening the support stiffness, in order to improve the use of hollow shaft to reduce system quality, etc. ( 1) In SUNTHAI bearing ( 轴承) Installation ( ān zhuāng) Before, should use the appropriate measuring tools according to the design ( Design) Drawing on technology ( 技术) Requirement, inspect shaft and hole and machining quality of parts ( Mass) ( Such as dimensional accuracy ( Accuracy) , shape accuracy and surface roughness, etc. ) 。 Thin wall bearings manufacturer of angular contact ball bearings can match the optimal number of balls and the contact Angle of 30 °. They support radial load is higher than contact bearing deep groove ball bearings or four o 'clock, and can support comes from the same direction of axial load. In view of the special demand, ( 2) Shaft and the bearing hole assembly there such as bruising, burr, rust stain on the surface or solid particles ( Such as abrasive dust, sand, clay) Such as existence, not only can make the self-aligning ball bearing installation difficulties and make the installation position is not correct, and solid particles such as falling into IKO bearings grinding effect, when self-aligning ball bearing rotating grinding or bruising IKO bearing work ( 工作) Surface, so must be carefully checked before the installation, if found to have the above defects, should be revised. For example using oil file to remove burrs, bump touch mark, rusty spot, with fine abrasive cloth lighting, and like a clean solid particles, dirt, etc. ( 3) Assembly shall be ( 组装) Surface with a clean gasoline, kerosene, toluene and xylene solution washing clean, again with dry clean duster cloth, coated with a thin layer of lubrication, lubrication) Oil ( 润滑油) , this can make the installation, operation 经营) It is more convenient. ( 4) In the installation, ān zhuāng) When open the self-aligning ball bearing, 轴承) Packaging and put it into the liquids such as gasoline with handle gently gently turning, to ensure the cage, encapsulated oil on the surface of the rolling element and raceway thoroughly washed clean. Bearing the use of clean environment for bearing is very important. Such as cross section thin-walled bearing ring rotation surface and rough surface precision of the rolling element is about 1/10 microns, this smooth surface of the ball if polluted, its influence is very serious. ( 5) Cleaning a lot SUNTHAI bearing ( 轴承) When use temperature (first 温度) Is 90 ~ 100 ℃ heat oil pour hot to melt encapsulated oil, at the same time with seamless all mouth and no net exfoliation tools to dig the old oil, then pour hot a few minutes, then use kerosene wash oil, clean with gasoline last again. After washing clean, should put on film ( Thin and soft transparent sheet) Gloves will be self-aligning ball bearing on the worktable of dry clean cloth or paper. ( 6) Note that with seal ( 密封) IKO bearings do not clean with this law, sealed internal cleaning should remain the same.
