Misalignment of a slide gate operator can cause what due to chain feeding over sprockets?

• A. Premature wear
• B. Increased opening angle
• C. Decreased power consumption
• D. Reduced motor temperature

Answer: (A)

When the chain doesn’t track properly over the sprockets, it doesn’t contact the teeth evenly. This misalignment causes the chain to ride up, rub the sides of the sprockets, and experience binding or side loads. Those abnormal contacts create higher, uneven friction and stress on the chain, sprocket teeth, and associated guides, so parts wear out faster than they should. That’s why premature wear is the correct outcome. The other effects aren’t typically observed from misalignment. It won’t change the actual opening angle of the gate, since that depends on the limit stops and geometry rather than chain tracking. It also wouldn’t reduce power use or motor temperature; the added friction and resistance from misalignment usually increase both current draw and heat.
