Spherical roller bearing type, bearing corrosion how

Mechanical equipment, bearing failure occurs, in the bearing is removed for maintenance, to record the appearance of the bearing, check the bearing lubricant inside the residual stock, to save lubricant sampling, kerosene or gas bearing for easy cleaning. Improper installation, About %) Use brute force: when installation, directly with a hammer percussion bearing to bearing damage, is the main cause of deformation; Installation does not reach the designated position, install a deviation or failure to bearing, bearing clearance is too small. Cylindrical hole bearing installed a, will be installing a good combination of inner ring and outer ring, angel from center to produce deviation, will slowly inside and outside the circle together is very important. Centigrade meter mounted on the host side of the benchmark half-coupling on special fixture, measuring platform and fabrication and installation, the magnetic table installed on the measuring platform, make the dial indicator of contact points to the prime mover and the cylindrical side half coupling end face, including the coupling end equidistance diagonal set up two pieces of dial indicator. The selection principles of the grease: work environment with water vapor, choose calcium base grease; High working temperature, choose sodium base grease; Work of moisture and temperature, choose the lithium base grease. A common way of configuration on the axial movement of the bearing is installed on the shaft end set of axial bearing with set ', and on the other side install set of axial movable bearing 'walk', in order to prevent the result of the axial heat bilges cold shrink stuck phenomenon. (date) (month) (year), class C repair smoke generator rotor is found that the generator excitation end bearing severe wear and shaft neck also serious wear and tear, damage to the oil film between the shaft and tile, increase the friction between the shaft and tile. This kind of bearings mainly take radial load, the bear radial load at the same time, can also carry a small amount of axial load, usually is not used for pure under axial load, such as pure axial load, only column of steel ball bearing roller, spherical roller bearing has two columns is mainly used to bear radial load, but also can withstand the direction axial load. Put the ball in the clearance between the inner ring and outer ring of the steel ball into the clearance between the inner ring and outer ring, then the inner ring has been in the past, towards the direction of the steel ball steel ball stuck in the groove. Example: RSR, bearing rust bearing encounter water will rust, if after water, will continue to slide, wheel is moisture volatilizes quickly, taxi meters about volatile completed. But for the instrument bearing or bearing for high-speed rotation, the application of clean cleaning oil washed away anti-rust oil, when the bearing is easy to rust, not for a long time. This is called needle roller, this USES the curve groove groove ball bearing, through the bearing can put the existing rotary motion into reciprocating linear motion bearings.
