Slewing Bearing doesn't turn how the slewing bearing causes and solutions to the sound

Abstract: Slewing bearing has a variety of functions such as rotation, transmission, fixation, etc., which is widely used in the real industry. But in the specific use, slewing bearing will sometimes rotate inflexibly, there are problems such as noise, we need to figure out the slewing bearing rotating and noise causes and solutions, the following is to introduce these aspects of knowledge, together with the understanding of the next.

First, the slewing bearing does not turn how the slewing bearing is able to withstand a comprehensive load of large bearings, can simultaneously withstand large axial and radial loads and tilting moments. However, in the use of slewing bearing bearings, we often find that slewing bearing bearings do not appear to turn the phenomenon, if you find slewing bearing bearings do not turn, how to deal with it? The following for you to introduce the slewing bearing bearings do not turn the reasons and methods of treatment: 1, the newly purchased products idle inflexible reason: please check the slewing bearing bearing production date, if the time is longer (such as half a year or more time), the climate is colder, it is possible that the raceway is mixed into the salt spray and other impurities, thus leading to the operation is not working (cold areas, winter is more prominent) to exclude: after the force such as can run and no other abnormalities can be used normally!

2, after the installation of the operation is not flexible reason: may be the host mounting surface and slewing bearing mounting surface is not good, resulting in the installation of slewing bearing bearing axial clearance can not compensate for the deformation of the slewing bearing bearing, slewing bearing bearing is in a negative clearance state, the rolling body in the raceway running difficulties (sometimes accompanied by a strange sound), or the size of the gear mesh, or the size of the gear card with a foreign body. Remedy: re-process the host mounting plane, so that the mounting plane meets the requirements, re-adjust the size of the gear meshing side clearance according to the requirements, in particular, pay attention to the position of the gear jump big, check to ensure that the size of the gear meshing position without foreign objects, exchange a slightly larger clearance slewing bearing.

3, the use of the process of running inflexible reasons: seal broken, resulting in foreign objects into the raceway (such as the use of poor working conditions, the raceway immersed in dust, etc.) to rule out the solution: check the size of the gear mesh situation, there is no foreign matter or broken teeth.

Second, the slewing bearing rattling what is the cause of the slewing bearing in the construction machinery has a good support, can safely and effectively ensure that the machinery can operate normally. However, in the face of the problem of slewing bearing noise, we do not know what causes, how to solve. The following is a comprehensive introduction to the causes of slewing bearing noise:1, the installation surface is not flat, the installation surface flatness is not up to the requirements, will cause the raceway to form a negative gap produce noise. In the installation, the installation is too tight and too loose will also trigger the slewing bearing rattling.2, slewing bearing raceway internal impurities, such as sand, iron filings, etc., these will cause the slewing bearing rattling, and at the same time, such a problem, in general, the machinery is difficult to run.3, the slewing bearing lack of lubricating oil, check whether the raceway is lack of lubricating oil, if it is the case of lubricating oil can be added to reduce the friction of the parts and components.

Slewing bearing rattling solution: 1, if the lack of lubricant, can be coated or added to the slewing bearing raceway, while the new slewing bearing to work every 100 hours, to be coated with lubricant, to ensure that the machinery will not be lack of lubrication in operation. 2, if there are internal impurities, it is necessary to clean it up. Note that in the cleanup must not use hard objects to clean up, will increase the defects on the surface of the slewing bearing, can be cleaned with soft objects, in order to effectively ensure the integrity of the surface of the product, and improve the service life. 3, if the installation is not flat, can be reinstalled on the slewing bearing. In the installation process to ensure that the installation surface is flat, and can not be too tight or too loose.
