Part of chain systems, sprockets have toothed wheels and perforated tracks that facilitate motion. They naturally wear down over time, but some common problems can lead to premature failure. The guide below will help you recognize the signs of issues to keep your machinery in top shape.

What Wears Down Sprockets?

1. Excessive Weight

Too much weight places stress on the chain, pressing it down between the sprockets and forcing them to work harder to rotate. Over time, the force can wear down the gear’s teeth and pitch.

Weight also stretches the chain, making it looser. As a result, the system might produce grinding sounds and vibrations. Never exceed the weight limitations of the machine to avoid this issue.

2. Poor Lubrication

Chain systems generate a lot of friction, so they need to be lubricated. During routine inspections, technicians should check to see if there is brown discoloration on the chain.

If so, have them apply anti-corrosion lubricants to the system. Lubrication reduces friction that can grind down the sprocket’s teeth. As a rule of thumb, schedule this service once every few months, even if no discoloration is present.

3. Misalignment

Loose connections and impacts can knock sprockets out of alignment. The chain then pulls harder in one direction as it operates, stressing the sprocket's teeth. Over time the teeth might weaken and bend.

Misalignment typically causes vibrations and frequent chain slipping. In most cases, a technician can correct the issue by tightening the connectors on the system. However, if the affected unit is too damaged, you may need to have it replaced. Inspect for shiny edges and thin sprocket teeth for visual signs of wear.
