Deformation of flexible gear of harmonic drive

open access: yesJournal of Physics: Conference Series, 2020
Abstract Harmonic drives have high load capacity, kinematic accuracy, and small weight and dimensions’ parameters, compared to other transmissions. Due to the variable stiffness in the areas of the teeth and tooth sockets, the toothed rim of the harmonic drive during bending takes the shape of a polyhedron.
