F&F cone hole bearing is directly will ring in fixed on tapered shaft, or use tight set, remove the sleeve installation to cylinder shaft. Large self-aligning bearing multi-purpose hydraulic installation.

Operation check

Bearing installation ends, in order to check for installation is correct, to check for operation, small mechanical can by hand rotating confirm whether rotate smoothly. Check the item B: have due to foreign body, scars and creasing and cause operation, flawed because of installation is bad, the installation seat processing bad and the spin torque, clearance by uneven too small, installation error caused friction seal torque and so on. If there is no exception may start power operation. Because of the large machine can't manual rotation, so no load immediately after the start to turn off the power, for inertial operation, and examined for vibration and noise, rotating parts if there is contact, and so on, make sure no abnormalities into power after operation. Dynamic operation, from no load start at low speed, slowly to improve conditions for rated operation. The test run in to check the matters, whether to have abnormal sound, the transfer of bearing temperature of leakage and lubricant, color change etc. In the test run if abnormal, shall be immediately suspend operation, and check the machinery, has the necessary to remove bearing inspection. Bearing temperature check from shell that general appearance of the gods. But use of oil hole, direct measurement of bearing outer ring temperature, more accurate. Bearing temperature operation began to rise, such as no abnormalities, usually l, 2 hours stability. If because of bearing or installation and other bad, bearing temperature will be sharply, the abnormal high temperature. The reason such as lubricants too much, bearing clearance is too small, installation bad, sealing device too friction. High speed rotating occasions, bearing the lubrication to the choice of methods such as the reason is wrong.
