The correct way to replace the slewing ring

2019-12-27

The slewing ring is a new type of mechanical parts, which is composed of inner and outer rings, rolling elements, etc. The slewing ring is a large-scale bearing that can withstand comprehensive loads, and can simultaneously bear large axial and radial loads and overturning moments.

Use such as ferrospectrometer or SPM or I-ID-1 bearing operating condition monitoring instrument to distinguish the bearing operating condition and determine the bearing

When to report for repairs, this is a more convenient and reliable method.

For example, when the HD-1 instrument is used, when the pointer approaches the danger zone from the warning zone, and the pointer does not come back after taking measures such as improving the smoothness, it can be determined that the bearing itself is the problem. At this moment, you can take advantage of the danger zone. , Report the bearing for repair. After all, how far away from the danger zone is to report for repair can be adjusted by experience.

Using such an instrument can make full use of the potential of bearing operation, report the bearing for repair in time, and prevent malfunctions. It is a safe and economic slewing bearing.

2) Use simple things to monitor

In the absence of the above instruments, the operator can hold a rod or wrench and other things that collide with the machine housing part closer to the bearing, and put the ear on the thing to listen to the sound of the bearing from the thing. Of course, it can also be modified with a medical stethoscope. .

Normal bearing working sound should be uniform, stable and not sharp sound, and abnormal bearing working sound has various intermittent, impact or sharp sounds. First, you must get used to the normal bearing working sound, and then you can grasp and distinguish the abnormal bearing working sound, and then through the accumulation of practical experience, you can further analyze what kind of abnormal sound corresponds to what kind of bearing abnormal phenomenon . There are many types of abnormal sound in slewing ring bearings, which are difficult to describe, mainly relying on experience accumulation.
