To detect the gear damage of the SAT87-Y5.5KW-96 reducer, you can use the following methods:
Appearance inspection:
Direct observation: Use the naked eye or magnifying glass to carefully check the surface of the gear to check for obvious cracks, fractures, peeling, and wear marks, and also pay attention to color changes, such as whether there are color changes caused by oxidation, rust or overheating.
Coating method: Apply a thin color coating to the surface of the gear, and then let the gear run in normal working conditions for a period of time. Remove the gears and check the wear of the color coating. Where the color coating disappears is usually the area with more severe wear.
Measurement check:
Dimension and geometric shape measurement: Use tools such as calipers, micrometers or gear measuring instruments to measure the gear's teeth thickness, tooth pitch, tooth surface roughness and radial jumping, etc., and compare it with the new product standard value to analyze whether there is wear or deformation.
Tooth shape inspection: Use a projector to enlarge the tooth shape and observe and compare the changes in the tooth profile, the distribution of wear and the amount of wear. This method is suitable for larger gears. The tooth profile can also be measured using a precision tooth profile or a stylus inspector.
Run check:
Vibration and noise monitoring: Vibration monitoring is performed on the lead end of the moving gear through sensors, analyze the noise spectrum, and determine whether there are problems such as eccentricity, tooth pitch error, tooth shape error, etc. Fierce wear gears often produce more noise and vibration.
Loading test: Perform a load test on the gear to check its operating condition under load. If there is unstable transmission, increased noise or abnormal temperature increase, it may be a manifestation of gear wear.
Lubrication system inspection:
Oil level and oil quality inspection: Check whether the oil level of the lubricant is normal and whether the oil quality has deteriorated or is contaminated. Deteriorated or contaminated lubricating oil may affect the lubricating effect of the gear and aggravate wear.
Metal Particle Analysis: Regular sampling and analysis of the metal particles content in the lubricant oil. The metal chips produced by wear will be mixed into the lubricant oil. The increase in the number of particles usually means that the wear of the gears is intensified.
