Bearing installation must be in a dry, clean environment under the premise. The installation should be carefully examined before the mating surfaces of the shaft and housing, processing quality of the convex surface of the shoulder of the end face of the trench and connected. All the surface of the mating connector must be carefully cleaned and deburred, bearing casting surface necessary raw Ex molding sand.
Bearing installation should be preceded with gasoline or kerosene clean and dry before use, and to ensure good lubrication, bearings are generally lubricated with grease, oil lubrication can be used also. Greased, should be used without impurities, anti-oxidation, anti-rust, extreme pressure grease functional advantage. Grease filling is 30% -60% of the bearings and bearing capacity of the container, not too much. With sealing structure double row tapered roller bearings and pump shaft bearings filled good grease, the user can be used directly, not cleaning.
Bearing installation, bearing necessary equal pressure is applied to the circumference of the ring face pressed into the ferrule the not hammer first class tools directly for percussion end bearings, so as not to damage the bearings. At room temperature in the case of the small amount of interference, with a sleeve onto the end face of the bearing rings, with the hammer beating sleeve, through the sleeve will be pressed into the ring balanced. Bulk installation, to be used in the hydraulic machine. Press-fitting, should ensure that the end face of the outer ring face and shell shoulder, inner ring end face of the end face of the shaft shoulder pressed, does not agree there is a gap.
Oil bath can be used when a large amount of interference, heating or induction heating bearings way to install, bearing heating temperature range 80 ° C to -100 ℃, the maximum can not exceed 120 ° C. The APPLIED nut or other suitable method of fastening the bearings, in order to prevent the bearing cooling after shrinkage in the width direction of the ferrule and the shaft shoulder a gap is generated between the.
Single row tapered roller bearings installed last clearance adjustment should be carried out. Clearance value should be determined in detail according to the different conditions of use and the amount of interference with the size. When necessary, should be determined experimentally. Double row tapered roller bearings and pump shaft bearing has been adjusted at the factory, good clearance, do not have to re-adjust installation.
Rotation test should be carried out bearing after installation, the first for a rotating shaft or bearing housing, bearing without exception, they no-load power, low speed, then gradually progress depending on the functioning of the rotation speed and load, and detects noise, vibration and temperature liter, abnormal, should repose operation and check. Normal operation test before delivery.
Bearing principle we all know, the bearings removed inherit the appropriate removal tool should be used. Removing the interference fit ferrule, only the tension applied to the ferrule, without dismounting force promised to pass through the immobile body, or move the body and the raceway will be crushed.
