Rolling bearings should be installed after the rotation test, the first for the rotary shaft or bearing box, without exception, they have no power to load, low speed operation, and then gradually increase as the functioning of the rotation speed and load, and to detect noise, vibration and temperature, abnormal, should stop and check. Test normal operation before delivery.
Rolling bearing installation: bearings must be installed in a dry, clean environment conditions. Before installation should check carefully with the axis and the shell surface, convex shoulder end, grooves and connecting surface processing quality. All connected with the surface must be carefully cleaned to remove burrs, casting is not processing surface must be the net sand.
Rolling bearing installation should be preceded with petrol or kerosene to clean, dry after use, and ensure good lubrication, FAG bearings the general use of grease lubrication, oil lubrication can be applied. With grease lubrication, should be used without impurities, antioxidant, anti-rust, extreme pressure grease such as superior performance. Amount of grease filled bearings and bearing box volume of 30%-60%, not too much.
Rolling bearing installation, must be applied equally in the circumferential ferrule end face of the pressure, will press into the ring, not directly strike the bearing end face to a tool, so as not to damage the bearing. Small amount of interference in the case, can be used to suppress sleeve bearing rings end at room temperature with a hammer, hammer sleeve, through the sleeve will be pressed into the ring balance. If the high-volume installation, use of hydraulic machine. Indentation, should ensure the outer end face and shoulder shell surface, inner end face and shoulder axis compression, does not allow a gap.
Rolling bearing the demolition: Bearing continue to be removed after use, should choose the appropriate removal tool. Interference with the demolition of the rings, can only increase tension in the ring, must not be allowed to pass through the rolling force demolition, otherwise the roller and raceway will be crushed.
Rolling bearing the use of the environment: selected according to the size, accuracy of location and conditions of use and environmental conditions, with the appropriate NSK bearings is the precondition of guaranteeing the bearing life and reliability of the.
1, using the site: joint load SKF bearings for radial and axial radial load to bear mainly the, usually with two sets of rolling bearings used in pairs, the main vehicle rear wheel, a driving bevel gear, gear, reducer and other transmission parts.
2, allow the speed: correct installation, lubrication good environment, allowing for 0.3-0.5 times the limit speed of rolling bearing. Under normal circumstances, the limit of 0.2 times the speed of the most desirable.
3, allow the tilt angle: tapered roller bearings are generally not allowed to tilt axis relative shell hole, if tilt, is less than 2′.
4, allow the temperature: under normal load, and the lubricant has high resistance to high temperature, and the full lubrication conditions, the general rolling bearing allows operation at -30 ℃ -150 ℃ temperature environment.
