POM pulley roller
Problem Phenomenon
POM pulleys show indentation deformation on the wheel surface under heavy load
Cause Analysis
POM creep accumulates under continuous heavy load, and the wheel surface indents when the contact stress is high; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience; this mechanism has been repeatedly verified by industry data and should be confirmed first during troubleshooting
Solution
Select reinforced grades for heavy-load pulleys; increase the wheel surface width to reduce contact stress; verify according to the load spectrum; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Key Takeaway
Heavy-load pulleys are selected according to contact stress and creep; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a reference for troubleshooting similar problems in the future
