After the slewing ring flange is installed, abnormal noise may occur in many projects? Why? Today, Shanxi Haokun flange Group Co., Ltd. mainly introduces the problem of abnormal noise of slewing ring flange. This angle of analysis is multifaceted and needs comprehensive research and analysis. It is normal that some slewing ring flanges that have just left the factory will make even steel ball rolling sound when idling. When the slewing ring flange operates after installation, another abnormal and large noise is called abnormal noise.
(1) The slight abnormal noise of new slewing ring flange when idling will generally disappear after tens of revolutions. If it does not disappear, it may be caused by the slight deformation of the slewing ring flange during transportation. However, if it operates flexibly and normally, it can be installed and used with confidence. It will disappear naturally after a period of use.
(2) If there is abnormal noise during the trial run after the slewing ring flange is assembled, check whether the mounting surface is smooth and meets the requirements. If the roughness of the mounting surface fails to meet the requirements, abnormal noise will occur due to the negative clearance of the raceway. The treatment method is the same as "inflexible operation after installation"; Or the engagement of the big and small gears is poor, sometimes tight and sometimes loose, and the abnormal noise is caused by the over tight engagement at the position with large tooth skipping.
(3) Abnormal noise occurs during the use of slewing ring flange. There are several reasons: the grease in the raceway is insufficient, and the noise caused by the collision between the rolling element and the spacer ring can be eliminated after timely refueling; Foreign matters, such as sand and iron filings, are mixed in the raceway. It is often accompanied by difficult rotation (which is usually easy to occur in the environment with poor working conditions).
