Bearing material: hot pack commonly used motor bearing installation

On the basis of theoretical model and using the existing experimental conditions, design a set of experiments, respectively with the design and measurement of the magnetic field experiments with experiment, magnetic fluids, magnetic viscosity measurement experiments in different operating conditions. Exerted pressure in some cases to rolling bearing in order to increase rigidity, this program is typically used for deep groove ball bearings, angular contact ball bearings and tapered roller bearing inner and outer circle of bias, shaft bending, shaft or the bearing box tolerance changes, cooperate with the mistake could lead to the eccentricity of the inner and outer ring. & micro; 米,HRC - , ceramic is incredibly sensitive in their pore impurities, so any contaminants may lead to premature failure. Is outside of tolerance, along with the increased amount of grease filling, bearing linear temperature increase, the same filling amount, sealed bearing temperature rise is higher than the open bearings. Burning-out sliding bearing low melting point alloy shaft current from the metal contact point of bearing and shaft through, because the metal contact point is very small, so the current density is big, in the instant high temperature, the local burning-out, bearing the burning-out bearing alloy under the action of ground pressure, splash, and so on the bearing inner surface burn out small pits or bearing inner surface is extruded bars arc scars. Cage of low vibration and low noise plastic cage bearings and rolling contact with body, smooth operation, flexible, no metal cage noise produced when in contact with the roller, can significantly reduce the noise to the db. Grease choice: the choice of grease as NSK bearings is according to the rotating speed, heat resistance, such as noise and aerodynamic moment for choice, requires us to grease the west can understand. P— — Glass fiber, nylon, after making crack section metallographic specimen observation, crack is fine, perpendicular to the surface, which did not see material mixed, scale, such as distribution, shape as shown. How to select and design suitable material according to different situations is a complex problem, although it was slight bumps, bumps, etc. , if you have to fine sandpaper to remove stone or oil. Baffle cer is annular parts, used in between the two bearing ring or bearing washer or two and a half between bearing ring or two and a half bearing washer to keep by axial distance between them. We see a lot of things at ordinary times, such as car, the door on many fields such as, where they use in the middle of the bearing is different, so the classification will be different. Equipped with nylon cage bearing can in - °- ° under long-term continuous stable work, work should not be more than hours when °, short peak temperature should not exceed °.
