What causes excessive noise in a geared motor?

Mechanical Structure Issues

Gear Damage:
Excessive wear and vibration between gears may result from low gear precision, manufacturing errors, pitch accumulation, or tooth profile errors. Pitting on the gear surfaces is another significant cause of noise, where small metal pieces may detach near the tooth line after the gears have been under load for a period, increasing operational noise and impact.

Bearing Issues:
Improper bearing clearance (too large or too small) or misalignment during installation can lead to noise during operation.

Insufficient Housing Stiffness:
If the gearbox housing lacks sufficient rigidity, it may deform during operation, causing noise.
