Methods of slewing ring failure detection and maintenance precautions
The slewing ring is an essential component of mechanical equipment; however, when it fails, it is likely to cause poor functioning of the complete mechanical equipment, compromising production efficiency and quality, thus slewing ring failure must be addressed promptly. Find out what it is and how to cope with it. So, what are the procedures for slewing bearing defect detection? What measures should be taken during maintenance?
I. Slewing bearing fault detection technique
1. Method of lubricant identification
The status of the lubricant can be used to determine if the slewing ring has failed. The specific approach entails taking a sample of the lubricant and analyzing it, as well as observing the degree of contamination and determining if it is contaminated with foreign matter or metal particles. This approach is very useful for grading slewing bearings or huge slewing bearings that are difficult to inspect.
2. Method for detecting temperature
The slewing ring's working temperature is used to identify it. When the operational condition of the slewing ring does not change considerably, this approach is employed as a comparative identification method. As a result, the temperature must be constantly monitored. When the slewing bearing fails, the temperature not only rises, but also fluctuates irregularly. Both functioning temperature recognition and voice recognition technologies should be used.

3. Method of voice recognition
Sound can be used to identify slewing bearing failures, but it takes a lot of practice and a lot of training to be able to distinguish between slewing bearing and non-slewing bearing noises. As a result, as much as feasible, a committed individual should be utilized to do this task. With a listening device or a listening stick attached to the shell, the sound of the slewing bearing may be plainly heard, allowing the failure and reason of the slewing bearing to be determined.
II. Precautions for slewing bearing overhaul
1. Take note of the slewing bearing's appearance.
When the slewing ring fails while using mechanical equipment, record the appearance of the slewing ring when disassembling it for maintenance, check the residual amount of lubricant inside the slewing ring, and after sampling and storing the lubricant, choose kerosene or gasoline for the slewing ring. It's only a matter of cleaning the support.
2. Do a rough wash first, then a delicate wash.
Clean the slewing bearing once it has been disassembled, and then clean it gently. Place the slewing bearing on the container and a metal mesh on the bottom to keep the slewing bearing from removing the dirt from the container's bottom. Avoid spinning the slewing ring with dirt when doing harsh cleaning to avoid harming the slewing ring's rolling surface. Proceed to the fine cleaning phase after removing the glue and oil with a brush. Clean the slewing bearing by dipping it in the cleaning oil and rotating it. Replace the cleaning oil when it becomes filthy to provide a great cleaning effect.
3. Make sure the slewing bearing is in good working order.
It is necessary to verify the dismantled slewing ring once it has been cleaned in order to confirm that it may be utilized again. Foreign matter, clearance, dimensional correctness, wear of the slewing ring frame, the state of the mating surface, the state of the rolling surface, the state of the raceway surface, the running state of the ball or roller, and so on are among the inspection items for the slewing ring.
The foregoing is an overview of slewing bearing defect diagnosis and detection methods. I hope it proves to be beneficial to everyone. If you want to boost equipment productivity, first and foremost, mechanical equipment performance must be high, and the slewing bearing has a stronger association with mechanical equipment performance. The mechanical equipment includes the slewing bearing. The slewing bearing in mechanical equipment must be recognized and examined throughout manufacturing and processing.
