Joints, rod end bearing, high heat oil bearing black how to deal with

Suitable strength and good temperature characteristics for the use of machine tool main uranium from high temperature and thermal deformation in the machine tool, influence machining precision or make poor lubrication bearing, should according to the structure of the spindle bearing, speed and bearing clearance to choose a suitable doneness of lubricating oil Wells for oil has good temperature characteristics show concern and prevent a spindle working temperature and environmental temperature change is big, teaching degree changes which affect its lubrication performance. Thrust ball bearing type, code-named, mm axial spacing, slow down the inner ring and clamping ring end face and wear; Slow tilt of bending roll and the influence of the thermal expansion of bearing inner ring and bearing load. Line is the first step on the installation, mainly from the beginning to the end to set the position of the line, and then according to the installation position of a half coupling is different for specific Settings and analysis. When the lubricant quality bad, bad, or containing impurities such as dust, sand, dirt or insufficient filling quantity or bearing box cover, seat of the connecting bolt force is too large or too small, also can cause this problem; The boiler fan bearing grease package not stipulated in the standard to join. So if we want to extend the service life of bearing, eight, after will spray lubrication oil atomizing spray on the surface of the friction, lubrication method, suitable for high speed bearing. Processing: to find center, self-aligning ball bearing self-aligning ball bearing is just for two columns, there are two inner ring raceway, the outer ring raceway is spherical shape, with automatic self-aligning performance. Countermeasures: bearing box to clean clean, replace the new oil seal, sauvy carbon nanometer polymer technology is relatively mature and high cost performance of maintenance scheme. Can distinguish the automobile rear wheel bearing is broken, the car accelerated after the slide in a neutral state, if buzzing sound did not change, so is the rear wheel bearing is broken. Completely liquid lubricated bearing friction power loss is low, but for static pressure sliding bearing, with the pump power losses, the total power losses may be higher than the dynamic pressure bearing. Analysis technology to solve the loose must have solid filler to fit clearance, to solve the oil must be centrifugal fan to bearing the wind problems, then puts forward with high-pressure injecting into the collar with axial clearance between injecting solve loose sleeves up wind, shaft sleeve outer ring and guide ring bearing oil change direction. Mm, bad lubrication lubrication on the service life of bearing and friction, wear, vibration and so on have important influence, good lubrication is necessary for normal operation of the bearing condition. The cause of the problem analysis: check carefully before assembly, for of type bearing seat, bearing cover and joint surface and outer race of bearing base between cylindrical surface, should be set aside.
