KOYO import bearing installation operation maintenance method is used

Installed correctly KOYO import bearings is the assurance of its service life extension, many people do not have the professional knowledge at the time of installation is not particularly in place, easy to cause the bearing to improper installation, mechanical operation of the prone to accidents, as a professional mechanical maintenance engineers must know something of the bearing installation. In general bearing installation is in accordance with, bearing structure, size, and part of the installation, and to determine the nature of the cloud, at the time of installation note when pressure is directly in the ring on the surface, must be vertical pressure, not by turning to pressure roller, bearing installed more general method is as follows: the bearing ring with shaft with way more for transition fit, KOYO import bearing seat and the bearing hole with more is clearance fit, the way the in general are relatively easy to install, in the center axis of the bearing should be on the shaft fixed well, lest the circumferential relative weeks rotation, lead to unnecessary wear and tear. Here bearing installation, rotating more some installation way, so that we can make inner ring can be more tight some axis. Bearing outer ring and bearing seat with relatively loose, the inner ring with shaft with relatively tight time, you can use to install bearing use professional press to the bearing pressure on the shaft, then install with shaft, bearing to the bearing seat, at the time of pressure installation note on crossroads to the face of the bearing inner ring, then pad made of a soft metal casing, the material is copper or mild steel is ok, the assembling casing diameter is greater than the diameter of a journal, outside diameter is larger than that of inner ring gear side was a little child, avoid pressure in the rack. KOYO import bearings after installation, in order to check whether installed correctly, check for running. Small mechanical can rotate with the hand, to confirm whether to rotate smoothly. Check project has caused by foreign bodies, scars, creasing seized up, due to bad installation, installation of seat processing bad moment is not stable, because the clearance is too small, installation error, seal friction caused by the torque is too big, and so on. If there is no abnormal can start power operation. Large machinery from manual rotation, so after no-load start immediately cut off the power, machine idle, check whether there is presence of vibration, noise, rotating parts contact, etc. , confirmed after no abnormalities, into power operation. Dynamic operation, from the beginning of the no-load speed, slowly up to the rated operating conditions. Test run to check the items, whether there is abnormal sound, the change of bearing temperature, lubricant leakage or discoloration, and so on. If discovery is unusual, should immediately stop, check machine, when it is necessary to remove the bearing inspection. Bearing temperature, average according to the external temperature of the bearing. But using the oil hole directly measure temperature more accurately KOYO import bearing outer ring. The bearing temperature, starting operation gradually increases, usually 1 ~ 2 hours after the temperature stability. If the bearing installation, the temperature will rise sharply, abnormal high temperature. The reason such as lubricant, bearing clearance is too small, too much bad installation, excessive friction sealing device, etc. High-speed rotation, the choice of the ways of bearing structure, the lubrication error and so on is also the reason. KOYO import bearing examination such as the rotation of the sound with a stethoscope, a strong metal noise, such as vision, irregular note that exception. Its reason has poor lubrication, shaft or precision bearing, bearing damage, foreign body intrusion, etc.
