KOYO cylindrical roller bearing cleanup and maintenance method

When KOYO bearing rotation, the bearing inner ring and outer ring raceway surface with rolling body is rolling contact, as the dark side, thus orbit trajectory are attached to the raceway surface does not belong to abnormal, the change can be learned that load conditions, so when the removal of cylindrical roller bearing, please keep close attention and observation on the surface of the raceway. If you look closely at orbit, will know that only bear radial load, bear the axial load of big, inherit the torque load, or extreme rigid in bearing box is not equal. Can check if the bearing with accidents such as whether the load and the installation error of kingdoms, and shall be investigated for KOYO bearing damage and you will become a reason for clues. Correct installation of cylindrical roller bearing is a guarantee 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, prone to accidents, mechanical operation of the as a professional mechanical maintenance engineers must with KOYO bearing installation. In general bearing installation is in accordance with the 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 bearings installed more general method is as follows: with shaft bearing ring with way more for transition fit, KOYO bearing seat with bearing hole with more is clearance fit, such cooperation way 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 turn, 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. Cylindrical roller 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 first, and then with shaft, KOYO bearing installed on 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. Because the lubricating oil is the protection of the bearing cannot little material, lubricating oil it can completely into the bearing internal space, cover the cage and rolling body, not only the operation of cylindrical roller bearing and working without any influence, but also greatly prolong the service life of bearing. But due to the frequently used lubricating oil, will produce certain oil, and oil pollution if not keep clear of in time will affect the service life of the lower bearing, so to remove grease. First, when clean the bearing KOYO bearing, should put the ball, pearl frame transverse transfer from the outer ring, internal ring into hot oil, again after a short cylindrical roller bearing when cleaning roller, beads, also should be the inner ring and outer ring off. Remember that in hot oil when cleaning, the oil temperature should not exceed 20 ℃. Second, soft dry oil or rust cream hardening bearing, should dip in 100 ℃ ~ 200 ℃ hot oil, clamp bearing with forceps, brush with wool clean oil bearing. Soft dry oil or rust creams are heated to 100 ℃ ~ 200 ℃, melting, easily washed out of the bearing gap. Sometimes as long as KOYO bearing repeatedly shaking in the oil. The oil into crevices from. Using the above two methods can easily remove the oil on the cylindrical roller bearing, in order to better play to the utility of lubricating oil, protect the bearing, extend the service life of bearing.
