Reasonable properly installed FAG thrust ball bearing effectively extend the service life

The installation of thrust ball bearing is reasonable, whether it is right, will directly affect the service life. Reasonable properly installed thrust ball bearing will greatly extend its service life, so the installation of assembly department for FAG bearing should fully study, carried out in accordance with the operation standard. Specific methods are as follows: the installation of the thrust ball bearing, due to the bearing structure, cooperate, conditions vary, due to the more commonly as the axis of rotation, so the inner ring need interference fit. Cylindrical hole bearing, multi-purpose press pressure into, or hot charging method. Taper hole, fixed on the cone shaft directly, or set set of installation. When installation, use the clearance fit, the outer ring has interference quantity, usually use the pressure into the press and or use after cooling installation method of the cold. Use dry ice as coolant, the cold installation, the moisture in the air condenses on the surface of FAG bearings. So you need to take rust prevention measures. Thrust ball bearings cylindrical hole in the mounting press press it into: widely used in miniature bearing press press it into. Block to inner ring, press gently pressure to the inner ring end face close to shoulder. Install inner ring, outer ring to resist pad will cause the roll channel of indentation or crushed, so absolutely forbidden. Furthermore, operation, should be greased the mating surfaces in advance. Installed with a hammer knock occasions, as a last resort to mat mat, circle piece of work. The practice repeatedly FAG bearing damage, so, only small amount of interference, the interference cannot be used for the large or medium and large amount of bearings. The separation type bearing inner and outer ring needs to be interference installation, as shown in figure 2, with a screw or hydraulic, using block will pressure into the inner and outer ring simultaneously. Outer ring is easy to lean, if not interference fit, also the best mat block installation. The separation type bearing inner and outer ring can be installed on the shaft and bearing seat. Will be installed inner ring and outer ring, the key is firmly closed, to prevent the center deviation, barely membership roll to surface abrasion. Hot charging method of large bearings, pressure fashionable takes a lot of power, so it is difficult to work. Therefore, widely used in hot pack: in oil heating FAG bearing, expansion, and then loaded on the shaft. Using this method, the force of improper installation will not happen, can shorten the operation time. Heating temperature of the bearing to the bearing size, the required amount of interference, refer to figure 3. Hot charging work related matters needing attention, as follows. ( a) Shall not exceed 120 bearing heating & # 65439; C。 ( b) Don't touch the bottom of the tank for the bearing, bearing should be put on the metal rack, or lift. ( c) In order to prevent operation, because of the inner ring temperature drop and difficult to install, heating FAG bearing should be higher than the temperature required 20 ° C - 30°C。 ( d) After installation, bearing cooling, the width direction also will shrink, so want to use the method of shaft nut or other appropriate, lock it, in case of clearance between inner ring and bearing retaining shoulder. Thrust ball should be heating device in addition to the oil hot charging, using the electromagnetic induction principle of thrust ball should be heating device is also widely used. Thrust ball should be heating device, excitation coil is installed inside, because of the electromagnetic induction effect, after the power supply current to the heating body ( Bearing) , the heat produced by the impedance of the bearing itself. So you can in a short period of time, without fire, oil evenly heating. Bearing hot charging high work efficiency, clean. Packing and unpacking the frequent occasions, such as roll bearing, railway vehicle axle box with cylindrical roller bearing, thrust ball special induction heating device can be used for installation, remove the inner ring. Finally talk about thrust ball bearing grease filling grease lubrication in general, not to clean FAG bearing, directly filled with grease. Oil lubrication, generally don't have to clean, however, instrument or high-speed bearing etc, to clean with clean oil, remove rust inhibitor) on the bearing. Remove the rust inhibitor of bearing, easy to rust, so can't put randomly. Also, has the bearing grease sealed, not directly use cleaning. Reasonable properly installed thrust ball bearing will greatly extend its service life, reduce FAG bearing cost for the user.
