Unlike a rigid gear, a harmonic drive relies on elastic deformation. The flexspline flexes with every rotation. This flexibility has a limit; eventually, the material will fatigue and crack. The harmonic drive market provides life data and design guidelines to ensure reliability. The Mechanism of Fatigue The flexspline is made of high-strength steel (e.g., maraging steel). The strain...
