PA6 Product Friction Abnormal Noise
Sorun Belirtisi
PA6 gears/sliders made abnormal noise during operation and wore quickly.
Neden Analizi
Dry friction on mating surfaces, dimensional changes after water absorption changing clearances; or wear powder shedding; PA6 water absorption expansion changes the mating clearance; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience.
Çözüm
①Design clearances according to wet-state dimensions;②select self-lubricating grades;③surface texturing to store oil;④establish regular wear monitoring and wearing part replacement system;⑤optimize mating materials.
Temel Çıkarım
PA6 friction parts 'design according to wet-state dimensions': water absorption expansion changes clearances; the clearance of nylon friction parts must be designed according to the use state (wet state), not the dry state.
