Motor-to-Gearbox Coupling Thermal Scan

Motor Shaft & Coupling

Coupling misalignment or improper lubrication of flexible coupling insert.

1.) Elevated heat at shaft connection point 2.) Heat dissipates unevenly along shaft axis 3.) No external signs of leakage or smoke

Asymmetrical heat signature at motor shaft-coupling junction with peak heat radiating at the coupling hub.

1.) Laser alignment check of motor-to-gearbox shafts 2.) Remove coupling guard and inspect insert for wear 3.) Perform vibration analysis to detect angular or parallel misalignment

1.) Schedule motor-to-gearbox alignment verification 2.) Grease coupling insert if applicable 3.) Monitor temperature trend weekly using IR route 4.) Conduct vibration test on horizontal and axial planes
