The causes of wear in dozer track chains can be attributed to several factors:

  1. Improper Tension: If the tension of the dozer track chain is too low, it can lead to slack in the chain, increasing sliding friction and impact loads between components. This is particularly damaging to the chain link and pin bushing. Conversely, excessive tension increases pressure between the relative moving parts of the walking mechanism, resulting in greater friction and accelerated wear.

  2. Excessive or Uneven Load Distribution: Prolonged use and poor working environments can result in surface wear on the dozer track chain, affecting the smooth operation and transmission efficiency of the chain.

  3. Poor Lubrication: The wear and fatigue of the chain, as well as wear and corrosion of the sprocket, are related to lubrication. Insufficient lubrication of the dozer track chain can accelerate wear.

  4. Harsh Working Conditions: Operating in wet, dusty, or highly corrosive environments can speed up the wear and corrosion of the dozer track chain, shortening its service life.

  5. Metal Fatigue and Friction Wear: Long-term use can lead to wear on the hinge elements of the dozer track chain, which is one of the most common phenomena.

  6. Poor Engagement Between Chain and Sprocket: Improper tension of the dozer track chain can lead to poor engagement with the sprocket, further exacerbating wear.

  7. Excessive Wear at Chain Links and Rollers: Over-wear due to contact between the track links and the rims of single-sided and double-sided rollers is referred to as "rail scuffing," which can also lead to accelerated wear of the dozer track chain.

  8. Poor Quality or Inappropriate Selection of Chains: Using low-quality chains or choosing the wrong specifications can also contribute to increased wear.

  9. Severe Wear of Chain Pins: Significant wear on the chain pins can result in the chain jamming and increased wear.

Various factors contribute to the wear of dozer track chains, including improper tension, excessive or uneven load distribution, poor lubrication, harsh working environments, metal fatigue and friction wear, poor engagement between the chain and sprocket, excessive wear between the chain links and rollers, as well as poor quality or inappropriate selection of chains. These factors can significantly impact the lifespan and performance of the dozer track chain.
