Therefore, the ball must be maintained regularly to clean the hinge support ministries, to be painted scroll bearing lubricants, ball bearing hinge combination even tighten the bolts, there are serious flaws in the hinge support to the timely replacement of the rocker shaft bearings should skew or tilt Even if the correction position, and so avoid the rolling surface is blocked. Ball bearing hinge routine maintenance, motor parts of the bridge abutment is under live load, temperature changes or other factors, to produce rotation, horizontal displacement, is the focus of the conservation of the site, taking into account the ball past highway bridge design hinge bearings, bearing a large extent, there is no set path of conservation work, the ball bearing hinge bearing maintenance personnel inaccessible parts of the long-term dystrophy, affecting the normal production of bridge maintenance work is not timely. So stressed Jiaqing for bearing maintenance, channel maintenance work to solve the problem of the working platform is necessary, therefore, ball bearing hinges in provisions for routine maintenance of the proposed bridge bearing a few requirements. Supports various components should be kept intact, clean, sweeping at least once every six months, oil and ball bearing hinge around, garbage, prevent water, snow, ensure the normal operation of the bearing. For the maintenance of a fixed ball bearing hinge hinge ball bearing, according to the highway bridge and culvert construction technology specification requirements, usually in trial operation period should be checked after a year, clearing debris and dust stand nearby, and carefully wipe with a veil of stainless steel dust plate surface. In other words, the ball bearing hinges year should such a style very necessary, between the rubber sheet is embedded in a spherical bearing hinge rubber layer prevents lateral expansion convex drum, while the shear stiffness of the bearing little impact in Under the horizontal force H effect, stiffening the amount of displacement of rubber bearings with rubber bearings produced by the level of non-stiffening deformation roughly the same. Ball bearing hinge meticulous long-term repair and maintenance work, check the ball bearing hinge bolt oil cut, ball bearing hinge cracking and aging rubber oil seals, bearing checking relative displacement is uniform, one by one discipline bearing displacement amount .
