Why Is My Industrial Gearbox Making Noise?

Why Is My Industrial Gearbox Making Noise?

Industrial gearboxes are essential in many applications, ensuring efficient power transmission and precise motion control. However, in some cases, these devices may emit noises that indicate technical or maintenance issues. Understanding the causes of noise is essential not only for solving the problem but also for prolonging the life of the gearbox, improving energy efficiency, and reducing maintenance costs.

Causes of Noise in Industrial Gearboxes

The main causes of noise in gearboxes include:

  • Incorrect alignment: Even a slight misalignment of the gears can cause high vibrations and noise.
  • Component wear: With continuous use, internal components of the gearbox may wear out, generating noise.
  • Insufficient or inadequate lubrication: Lubrication is essential for reducing friction; insufficient lubrication causes excessive noise.
  • Hertzian pressure effect: This phenomenon occurs when the gear teeth are subjected to high pressures, causing stress and noise.

Let’s see how Riduttori Italia addressed a real case of noise caused by the Hertzian pressure effect, using innovative techniques and precise calibration.

Case Study: Intervention on a Large Noisy Gearbox

Recently, Riduttori Italia was called to intervene on a large gearbox emitting abnormal noise. The primary cause was identified as the Hertzian pressure effect, a phenomenon that can occur when gear teeth experience excessive pressure during contact. This type of pressure, if not managed, can lead to not only high noise levels but also premature wear and potential malfunction of the entire machinery.

To solve the problem, we implemented a recalibration strategy for the gearbox. This operation allowed us to:

  • Recalibrate the alignment and pressure applied to the gear teeth.
  • Reduce the Hertzian pressure effect, thereby decreasing the noise level.

The intervention was successfully completed, providing the client with a perfectly functioning and significantly quieter gearbox, without the need to replace the entire unit.

Proposed Solution: Gear Tooth Optimization

For those wishing to prevent similar phenomena and further improve the gearbox's quietness, Riduttori Italia recommends gear tooth optimization. This technique allows:

  • Minimizing vibrations and noise: By optimizing the shape and geometry of the tooth, critical contact points that generate stress are reduced.
  • Increasing gearbox durability: An optimized tooth is less prone to wear, ensuring more durable performance.
  • Improved efficiency: Reduced vibrations allow for smoother operation with lower energy loss.

Noise in industrial gearboxes is not only annoying but may also indicate technical issues that, if ignored, could lead to severe and costly breakdowns. The experience of Riduttori Italia demonstrates that targeted interventions, such as recalibration and tooth optimization, can effectively resolve these issues. We recommend that anyone managing industrial plants constantly monitor the noise levels of their gearboxes and seek qualified professionals to maintain the performance and longevity of their machinery.
