Jarring sound and its control method LNSERTED bearing jarring sound cylindrical roller bearings the harsh metal friction sound may occur on all occasions, mostly in the larger models bearing grease lubrication in base oilmore susceptible to performance degradation of the grease, and almost no oil lubrication.
In addition, more likely to occur in the winter, when exposed to pure radial loads, radial clearance occasions prone, and comes with a seat different size models of spherical bearings, likely to occur within a certain speed range both occur consecutively will intermittent. Outer ring raceway special processing method can prevent jarring sound appear necessary choice of such bearings or appropriate to reduce the radial clearance of the bearing, use the excellent performance of the grease and increase the rigidity of the bearing match parts .
(1) correct installation, spherical bearings are used for the seat belt is very important. I hope that we can use the correct installation method.
(2) the installation, according to their type and size, select machinery, such as heating or hydraulic methods. Bearing installation LNSERTED applied force, must not pass through the rolling elements from a bearing ring to the other bearing ring raceway otherwise it might be caused by the damage. But in any case, do not directly hit the bearing ring and the cage, the rolling body or the seal member.
(3) Replace the eccentric sleeve. First eccentric condom sleeve bearing eccentric steps, and smooth shaft rotation direction of tightening by hand. Then a small iron bar into or withstand the eccentric sleeve counterbore. To hand hammer along the axis of rotation direction percussion small iron bar. So that the socket head cap screws the eccentric sleeve securely installed, the last eccentric locking sleeve.
