Diagnostic Method for Transmission Belt Noise

Transmission belt noise may be one of the common problems in mechanical systems. Here are some methods for diagnosing drive belt noise:

Observation and auditory examination

By observation and auditory examination, it is possible to preliminarily determine the source of noise from the drive belt. Here are some observation and auditory considerations:

Appearance inspection: Check the belt for cracks, wear, or other obvious damage.

Tension: Check the tension of the belt, whether it is too tight or too loose may cause noise.

Foreign objects: Check if there are any foreign objects or impurities attached to the belt.

Auditory examination: Use a stethoscope or bare ear to listen to the running belt, paying attention to any abnormal friction or abnormal sounds.

Steering noise

Check the steering noise in the drive belt system, which may be caused by the following reasons:

Sliding: The sliding between the belt and the rollers may produce harsh noise.

Misalignment: Belt and roller misalignment may cause additional friction and noise.

Bearing failure: Check if the bearings in the transmission system are faulty, as damaged bearings may cause noise.

vibration analysis

Use vibration analysis tools to diagnose belt noise by monitoring and analyzing the vibration of the transmission system. Here are some methods for vibration analysis:

Spectrum analysis: Using spectrum analysis tools to detect vibrations of different frequencies and determine possible fault sources.

Phase analysis: Analyze the phase of vibration signals to determine whether the relative motion between different components is normal.

Vibration mode: Study the vibration mode under different working conditions and identify the source of abnormal vibration.

temperature monitoring

Monitor the temperature of various components in the transmission system, as overheating may be one of the indicators of noise issues. Pay attention to the following aspects:

Friction generates heat: Excessive friction may cause local heating.

Lubrication issue: Insufficient or excessive lubrication can cause temperature abnormalities.

The combination of the above methods can provide a more comprehensive diagnosis of transmission belt noise issues and take appropriate maintenance measures.
