This article presents a real-diverd case study focusing on troubleshooting shaft failures and coupling failures in industrial machinery. It highlighs common causes, diagnostic steps, and solutions to prevent future issues.

Background of thee Case

Te machinery implived was part of a manufacturing line e that experienced frequent downtime due to unexpected shaft and coupling failures. Te equipment operated under high torque and variable loads, which contriced to mechanical stress.

Inicial Symptomy a d Inspection

Operators reportoded abnormal vibrations and noise during operation. Visual chection revealed signs of wear and misalignment in that e shaft and coupling consignents. No immediate signs of magaration failure or corrosion were observed.

Diagnostic Process

Te accessance team diadted a detailed analysis, including vibration analysis, alignment checs, and material testing. They identified excessive misalignment and signs of autigue in thoe coupling material. Te shaft showed provideence of bending and surface crags.

Root Cause and Solutions

Te primary cause was improper alignment combine with operating conditions exceeding design specifications. To address this, thee team realigned the shaft and substitud thae coupling with a high- torque, flexible type. They also implemented regular accesse checs and improvized guadd management.

  • Regular alignment verification
  • Use of high- quality, flexible couplings
  • Monitoring vibration levels
  • Training operators on propr operation
