Turntable bearing is currently used in large-scale machinery, one of the key power components, and his normal operation is directly related to the stability of the relevant machinery. A customer reaction found in the use of turntable bearing operation is not smooth phenomenon, Luoyang Yu Jie Slewing Bearing Manufacturing Co., Ltd. to share with you a brief look, the use of turntable bearings may encounter three kinds of turntable bearing failure response plan.
Option One, the newly assembled slewing ring bearing product is not smooth running
① Check the turntable bearing production date, if longer, the climate is cold, there may be a large grease sticky rolling Road, resulting in poor operation, more prominent in cold winter.
② The newly assembled rotary turntable bearing products do not smooth the solution is not smooth If afterburner operation and no other abnormalities can be used normally, such as with abnormal sound, check whether there is serious trauma in the transport process, and feedback to our sales Out of service department processing.
Option two, re-assembly turntable bearing operation is not flexible
① excluded is not because the host installation surface and the turntable bearing mounting surface with poor, resulting in the installation of the turret bearing axial clearance can not compensate for the turntable bearing deformation. Turntable bearings in a negative gap state, the rolling element in the raceway operation difficulties (sometimes accompanied by abnormal sound); large and small gear meshing or foreign objects within the gear.
② re-assembly turntable bearing operation is not flexible approach
(1) re-processing the host installation plane, so that the installation plane to meet the requirements; or use pads to enrich the law.
(2) re-adjust the size of the gear meshing backlash, in particular, pay attention to the maximum gear beating position.
(3) check to ensure that the size of the gear meshing position no foreign body.
(4) Exchange a slightly larger turntable bearing.
Option three, daily use in the process of using the disc bearing operation is not flexible
① lack of grease, filled as required
② seal rupture, causing foreign matter into the raceway (such as the use of poor conditions, the raceway intrusion of dust, etc.).
③ check the size of gear meshing, with or without foreign objects broken teeth.
