What is a common cause of gear wear in drive systems?

• A. Misalignment
• B. Inadequate lubrication
• C. Overload
• D. All of the above

Answer: (D)

Gear wear in drive systems typically comes from three common factors: misalignment, inadequate lubrication, and overload. Misalignment causes uneven loading across gear teeth, which concentrates wear on the edges and can lead to early tooth damage. Inadequate lubrication reduces the protective film between teeth, increasing metal-to-metal contact, friction, and wear, sometimes causing scuffing or pitting. Overload pushes teeth beyond their designed contact stress, accelerating wear and surface damage. Any one of these issues can drive wear, and together they cover the main ways wear happens, so all of the above is the best answer. To prevent wear, ensure proper alignment, maintain adequate lubrication, and operate within the system’s load limits.
