1. Visual inspection: Visual inspection is the most basic method to detect the degree of wear of planetary reducers. First of all, the exterior of the reducer should be regularly inspected to observe whether there are obvious physical damages such as cracks, dents, deformation, etc. The external inspection should also include the inspection of fasteners, seals and other external parts to ensure that they are not loose or damaged. When conducting internal inspections, the reducer needs to be disassembled and the key components such as internal gears, bearings, and housings need to be carefully inspected. Whether the tooth surface of the gear is worn, peeled, or cracked; whether the bearing has raceway wear, rolling element damage, cage damage, etc.; whether the inside of the housing is worn, cracked, etc. are all areas that need special attention. In addition, it is also necessary to check whether the lubrication system is normal, whether the lubricating oil is clean, and whether there are contaminants. Through these intuitive inspections, the wear of the reducer can be preliminarily judged, and necessary maintenance measures can be taken. 2. Vibration analysis: Vibration analysis is a method of judging the state of the equipment by detecting the vibration signal during its operation. During the operation of the planetary reducer, the worn gears or bearings will produce abnormal vibrations, and these vibration signals can be captured by vibration analysis instruments. Vibration analysis usually includes two aspects: frequency analysis and amplitude analysis. Through frequency analysis, vibration components of specific frequencies can be identified, which may be related to specific mechanical faults (such as gear wear, bearing failure, etc.); through amplitude analysis, the intensity of vibration can be evaluated, and changes in intensity are usually related to the degree of wear. When using vibration analysis, the vibration data of the reducer should be measured and recorded regularly, baseline data should be established and compared and analyzed. Abnormal vibration patterns and significant changes in amplitude are early warning signs of wear, which need to be taken seriously and further inspected and maintained.

3. Temperature monitoring:
Temperature monitoring is a method of judging the state of the reducer by measuring its temperature during operation. Worn gears or bearings usually increase friction, which causes the operating temperature of the reducer to increase. By using equipment such as infrared thermometers or thermocouples, the temperature distribution of the reducer can be monitored in real time. If an abnormal increase in temperature is found, especially if the local temperature is significantly higher than the normal level, it is likely that the wear is caused by increased internal friction or insufficient lubrication. In addition, the working state of the lubrication system can also be checked by temperature monitoring. Deterioration of the lubricating oil or insufficient lubrication can also cause temperature increases. Regularly recording temperature data and comparing and analyzing it with historical data can help identify trends in temperature changes and detect potential wear problems early.

4. Noise detection:
Noise detection is a method of judging the state of a device by listening to the noise it makes during operation. Worn gears or bearings usually make abnormal noises, which can be captured by tools such as acoustic detection equipment or listening sticks. When performing noise detection, professional equipment should be used to record noise signals and perform spectrum analysis under the condition that the reducer is operating normally. Abnormal noise spectra and characteristics can reflect specific wear problems. For example, gear wear may cause increased meshing noise and frequency changes, while bearing wear may cause increased rolling noise and noise. In addition, attention should be paid to the changing trend of noise, and noise data should be detected and recorded regularly. Inspection and maintenance should be carried out in time when abnormal changes are found. Noise detection, as a non-invasive detection method, can be carried out during the operation of the equipment, with the advantages of real-time and high efficiency.

5. Lubricant analysis:
Lubricant analysis is a method of judging the state of the equipment by detecting the components in the lubricant. Wear inside the planetary reducer usually produces metal particles and other wear substances, which are mixed into the lubricant. By taking samples regularly and performing oil analysis, the metal particle content, particle size, composition and other parameters in the lubricating oil can be detected to determine the degree of wear of the reducer. Oil sample analysis usually includes spectral analysis, particle counting, viscosity test, water content detection, etc. Spectral analysis can identify different metal components in the oil, particle counting can evaluate the number and distribution of particles in the oil, viscosity test can detect the degree of deterioration of the lubricating oil, and water content detection can evaluate the contamination of the lubricating oil. Through these analyses, the state and wear of the lubricating oil can be fully understood, and timely measures can be taken to replace the lubricating oil or perform maintenance.

6. Torque and power test:
Torque and power test is a method of judging the state of the reducer by measuring the output torque and power of the reducer under different loads. Worn gears or bearings will cause the efficiency of the reducer to decrease, thereby affecting the performance of the output torque and power. By testing the torque and power output of the equipment under different working conditions and comparing them with the rated values, its performance changes can be evaluated. If the actual output is significantly lower than the rated value, it may be due to reduced efficiency caused by wear. Torque and power tests usually require the use of dedicated test equipment and are carried out under standardized conditions. The test results can help identify the cause of performance degradation and provide reference data for subsequent maintenance and repair. In addition, regular torque and power tests can establish a historical record of equipment performance and analyze its changing trends, so as to better predict and prevent wear problems.

7. Gear meshing analysis:
Gear meshing analysis is a method of judging the state of gears by detecting their meshing conditions. The gears of planetary reducers will wear out during long-term operation, resulting in problems such as changes in tooth shape and increased tooth gap. Using a gear meshing analysis instrument, you can detect parameters such as gear meshing accuracy, tooth shape, and tooth gap. Changes in meshing accuracy usually reflect the degree of gear wear. Abnormal changes in tooth shape may be caused by wear or deformation of the tooth surface. Increased tooth gaps can lead to increased transmission clearances and unstable meshing. By performing gear meshing analysis regularly, you can timely discover and evaluate the wear of gears and take necessary adjustments and repair measures. In addition, gear meshing analysis can also help optimize gear design and manufacturing processes and improve the wear resistance and service life of gears.

8. Periodic inspection and recording:
Periodic inspection and recording are important measures to maintain the normal operation of planetary reducers and extend their service life. By establishing detailed maintenance and inspection records and conducting regular comprehensive inspections of reducers, wear problems can be discovered and resolved in a timely manner. Periodic inspections should include visual inspections, vibration analysis, temperature monitoring, noise detection, lubricant analysis, torque and power testing, gear meshing analysis, and other aspects. The results of each inspection should be recorded in detail, including the inspection time, inspection method, inspection data, problems found and their treatment measures. By comparing and analyzing inspection records from different time periods, the development trend of wear can be evaluated, possible problems can be predicted, and a scientific maintenance plan can be developed. Good record and management systems can help companies improve equipment management, reduce downtime, and reduce maintenance costs.
