Endoscopic-Gear-Inspection

Endoscopic gear inspection is a non-destructive testing (NDT) technique that uses a flexible or rigid endoscope (borescope or videoscope) to visually inspect internal surfaces of gears and gearboxes without disassembly. It’s especially useful in aerospace, power generation, and heavy industry, where downtime and teardown costs are very high. Uses an optical device with a camera, fiber optics, or digital sensor to enter tight spaces inside gearboxes. Provides real-time video and high-resolution images of gear teeth, surfaces, and lubrication conditions. Can be paired with measuring tips or software overlays to evaluate defects like pitting, scuffing, or spalling.
