V-belts are important for transferring power in industrial machines for pumping systems, HVAC systems and mining equipment, amongst others.

This makes them an efficient and adaptable component needed for your machine.

However, even the most efficient mechanical parts are prone to wear and failure over time.

While you cannot maintain a pristine condition for your V-belts because they will wear out over time with each use, understanding the failure symptoms and implementing solutions early can help you from frequent and premature breakdowns.

This article will discuss symptoms of v-belt failure in machines and offer solutions to keep operations running smoothly.

1. Premature V-Belt Failure

Neglecting a belt will cause its abilities to falter and slip, leading to premature failure that could disrupt your operation.

Examples of common premature failures are load-carrying failure and edge cord failure.

1.1 Load Carrying Failure

When a V-belt is unable to withstand the designed weight, load-carrying failure happens, resulting in premature failure.

Excessive stretching, cracking, or tearing of the belt's material commonly causes this type of failure.

Symptoms:

• A sign of cracks, tears or fraying along the length of the belt.

• The belt grooves or ribs have significant wear or damage.

• Visible distortion or elongation of the belt.

1.2 Edge Cord Failure

2. Severe or Abnormal V-Belt Wear

The constant transfer of power between shafts will definitely show an inevitable sign of wear for the V-belt over time.

Similarly, ijedr.org also added that signs of wear can be caused by the influence of environmental conditions such as extremely high or low temperatures during an operation.

However, it is important to monitor any abnormal signs of wear to prevent the V-belt from deteriorating and failing.

Symptoms:

• Stiff or hard on the sidewalls of the belt.

• Bottom wear that are more excessive as compared to other parts.

• Cracks or splits on the belt surface.

  
  

3. Solution to V-Belt Failure and Abnormal Noise.

3.1 Load-carrying Failure

• Reduce Overloading: Distribute loads evenly across multiple belts or consider upgrading to a higher-rated belt if necessary.

• Inspect Pulleys and Sheaves: Check for worn or damaged pulleys that may cause uneven loading on the V-belt.

• Optimise Tensioning: Use tension gauges or tensioning tools to adjust belt tension within recommended levels based on manufacturer guidelines.

  
  

  
  

3.2 Edge Cord Failure

• Address Misalignment: Misaligned pulleys can cause edge cord failure because of increased stress on the belt's edges.

• Inspect Pulley Grooves: Smooth out any imperfections in the pulley grooves or consider using belt guides to prevent edge wear.

• Use belt guard: Protect the V-belt from damage by using a belt guard. This will prevent it from touching rough surfaces, making it more vulnerable to damage.

  
  

  
  

3.3 Abnormal Wear

• Address Misalignment and Tension: Misaligned pulleys or improper tensioning can cause abnormal wear patterns on V-belts. Address these issues promptly to ensure even wear across the belt's surface.

• Check the environment: Extreme heat, humidity, or chemicals can make V-belts wear out faster. Implement measures to mitigate these conditions or use specialised belts designed for challenging environments.

• Correct Belt Type: Use V-belts specifically designed for the application's operating conditions and environment. Different belt materials and constructions offer varying levels of resistance to wear, ensuring optimal performance and longevity.
