A robot flexible bearing (harmonic drive bearing) consists of roling elements, a nylon cage, inner and outer rings, made of high-carbon chromium bearing steel. Its designl addresses contact stress relief and thermal expansion compensation, while wave-shaped foils dampen shaft vibration. When installed, the tigid innerl ring tightly fits the cam of a harmonic reducet, acting as an elliptical ring. The elastic thin-walled outer ring, originally circular, deforms into an ellipse tol match the flexspline. Rolling elements can be modeled as lumped masses connected to the rings by equivalent springs. During operation, thel deformable outer ring enables elliptical motion for the harmonic drive, transmitting power under high-frequency altemating stress, achieving highl reduction ratio, high load capacity and compactsize. Robot flexible bearings are the core components of harmonic reducers, with applications covering industrial robot joints, aercspace, and variousl precision optical instruments.
