Regularly inspecting the transmission components of an Automatic Elliptical Printing Machine is key to establishing a comprehensive system that includes daily inspections, periodic in-depth inspections, and condition monitoring, with a focus on the wear of gears and bearings.
Daily inspections are fundamental and must be performed daily. Check the reducer for oil leaks and cracks. Touch the casing to check for abnormal temperatures (it should be warm but not hot). Listen to the running sound for smoothness and any unusual noises or impacts. Also check that the lubricating oil level is within the standard range, and that the oil is clean, without emulsification, deterioration, or impurities.
Periodic in-depth inspections should be performed monthly or quarterly. Use oil analysis to detect the content of metal particles (such as Fe and Cr) in the lubricating oil to determine the degree of wear on gears and bearings. Regularly disassemble and inspect the gear teeth for pitting, scuffing, uniform wear, or tooth root wear, and measure whether the tooth thickness has decreased by more than 10%. Inspect the bearing rolling elements and raceways for scratches and corrosion, ensure smooth rotation, and measure the bearing clearance to ensure it does not exceed 0.15mm.
Condition monitoring can be performed using specialized equipment. Vibration sensors monitor vibration amplitude; abnormal vibration may indicate gear wear or bearing failure. Temperature sensors monitor bearing temperature; a warning is needed if the temperature rises too quickly or exceeds 75℃. Laser displacement sensors monitor shaft misalignment; attention is required if radial deviation exceeds 0.03mm or axial runout is greater than 0.08mm.
If, during inspection, gear tooth thickness reduction exceeds 10%, bearing clearance exceeds 0.15mm, or abnormal vibration or temperature is found, worn parts should be replaced promptly to avoid affecting printing accuracy and equipment lifespan. Simultaneously, maintain equipment cleanliness and regularly change lubricating oil to ensure proper lubrication; this is crucial for preventing abnormal wear of transmission components.
