Development of Harmonic Drive Combining Four Arcs for Conventional Kinematic Application

This paper proposes a modified harmonic cam, which is used to design drive. Conventional drives using sinusoidal cam type pertain an elastic body concept and are thus difficult evaluate. Unlike the conventional proposed involves combination of four arcs. Such cams can be designed based on rigid concept, thus, tooth profile analyzed established gear theory. The novel by exploiting four-arc combinations, guides for designing with involute cycloid angular teeth presented. A drive difference two between circular spline flex designed. operation, engagement, interference validated through mock-up production 3D printer simulation program. findings facilitate facile manufacturing drives.
