High temperature bearing shaft bearing system requires both high rigidity, and asked for quality light as far as possible, in order to overcome this problem, can take such as lower surface roughness and improve surface strengthening measures to improve the stiffness, the use of hollow shaft to reduce system quality etc.
(1) in the high temperature bearing before installation, should use the appropriate measurement tools according to the design drawing the technical requirements of the regulation, check the shaft and a hole and the relevant parts processing quality (such as size accuracy, the shape accuracy and surface roughness, etc.
(2) axis and the bearing assembly on the surface such as holes have bruising, burr, rusty spot or solid particles, such as abrasive dust, dirt and sand) exist, not only can make FAG installation and bearing installation position is not correct, and solid particles such as fall into high temperature bearings inside will work abrasive, when bearing rotation FAG will abrasion or scratches the surface of high temperature bearing work, so before installing must be carefully checked, such as the discovery of the defect, be amended. For example using oil file to remove burr, convex touch the mark, rusty spot, and fine sand cloth lighting, and as cleaning solid particles, dirt etc.
(3) the assembly should be in a clean surface of gasoline, kerosene, toluene, xylene or cleaning solution clean, dry and clean duster cloth, besmear again putting a thin layer of oil, so can make installation operation more convenient.
(4) the installation open FAG bearing encapsulation, and dip it in the liquid such as gasoline to handle gently slow to turn, to ensure that maintains a, roller and groove surface the encapsulation of the oil to be cleaned thoroughly clean.
(5) of high temperature bearings cleaning, use first temperature of 90 ~ 100 ℃ hot oil pour hot to make packaging oil melting, at the same time use the seamless mouth and do not fall scurf dig net all old oil tool, drizzle hot a few minutes and then rinse with kerosene to oil, and finally to use gas cleaning it again. After washing clean, should wear gloves will FAG bearing on thin film on the clean cloth or the paper to dry.
(6) note with high temperature bearing seal not with this law cleaning, sealed internal should remain the same shall not cleaning.
