Bearing is installed later, it is necessary to determine whether it is properly installed, to bearing operation of security, stability and long life. What about how to determine the bearing is installed correctly? From the following three sources said.
First, after installing the bearings, to run checks, fluency is normal. Small machine can rotate to confirm whether it rotates smoothly. You should check for foreign bodies, scar, indentation caused to seize up. In case of improper installation, mounting the torque produced is unstable, as the clearance is too small, of course, installation error, seal friction can also cause this problem.
Then, check the bearing temperature, you can through the external temperature of the bearing seat speculated. Directly measure the temperature of the bearing outer ring is more accurate, of course. Typically, bearing temperatures from the operation gradually began to rise, stabilized in 1-2 hours. If adverse bearing installation, temperature rises dramatically, unusual high temperatures. Perhaps due to excessive lubrication, the bearing clearance is too small, poor installation, such as excessive seal friction.
Best sound-check the bearing rotation. We usually use stethoscopes to check if bearing a strong noise when running, different sound irregular sound occurs. Due to poor lubrication, shaft or housing bore poor accuracy, bearing damage, foreign body invasion.
After the installation is complete, as long as a good grasp of these three aspects, will be able to determine the bearing is correctly installed.
