In order to check for proper installation, run checks to. Small mechanical hand rotation, to confirm that the rotate smoothly. Check the project due to foreign body, caused by scars, indentation to seize up, because of the bad installation, mounting process arising out of the bad moments are not stable, owing to the clearance is too small, caused by installation errors, seal friction torque is too large, and so on. Without exception you can start power function.
Bearing temperature, generally according to the external temperature of the bearing seat to speculate. Uses of oil hole direct measurement of the temperature of the bearing outer ring is more accurate. FAG bearing temperature, from a running start rising, usually temperature-stable after 1-2 hours. Bad if the bearings are mounted, the temperature rises dramatically, exception occurred at high temperature. The reason such as excessive lubricant, bearing clearance is too small, poor installation, sealing device too much friction. Occasions of high speed rotation, selection of bearing structures, lubrication is also the cause of the error.
To fully meet the carrying capacity of FAG bearings, bearings inner and outer rings (or after the shaft washer of the thrust bearing washers) the entire circumference must be completely solid and uniform support, seating can be cylindrical or conical surfaces, in order to check for proper installation, run checks to. Small mechanical hand rotation, to confirm that the rotate smoothly. Check the project due to foreign body, caused by scars, indentation to seize up, because of the bad installation, mounting process arising out of the bad moments are not stable, owing to the clearance is too small, caused by installation errors, seal friction torque is too large, and so on. Without exception you can start power function.
A. noise and vibration random;
B. vibration frequency of more than 1kHz;
C. regardless of the speed change, noise main frequency is almost unchanged while the sound pressure levels increase with the speed increase;
D. when radial internal clearance increases, sharp increase in the sound pressure level;
E.FAG rigid bearing increases, lower the overall sound pressure levels, even if the speed increased, the overall sound pressure levels also increase is unlikely;
F. lubricant viscosity higher sound pressure levels lower, but for grease lubrication, its viscosity, SOAP shape size can affect the noise values of the fiber.
