Abstract

A gear device for which a commercially available bearing can be used, in which a tooth jump does not occur, and which has small moment of inertia. A rocking gear device (10) has a rigid internally toothed gear (20), a flexible externally toothed gear (30), and a rocking generator (40). The rocking generator (40) has two circularly outlined eccentric rollers (41) each provided with an eccentric cam (42) rotating on the center thereof eccentric a specific amount, a bearing (43), and a wheel (44). The eccentric rollers (41) are arranged overlapped on each other such that the centers of the circular outlines of the eccentric rollers (41) are spaced from each other a predetermined amount from the rotation axis XX in the directions opposite to each other. When the outer peripheral surface of an eccentric roller (41) makes contact with the inner peripheral surface of the flexible externally toothed gear (30) to deflect the flexible externally toothed gear (30) so that the flexible externally toothed gear (30) partially meshes with the rigid internally toothed gear (20), the curvature radius R at the point of meshing of the flexible externally toothed gear (30) satisfies the expressions of 2 (ε + R) = m Zc and 2 π R + 4 ε = π m Zf (where R is the curvature radius the flexible externally toothed gear measured at the point of meshing, ε is the amount of eccentricity of the eccentric rollers, m is a module, Zc is the number of teeth of the internally toothed gear, and Zf is the number of teeth of the externally toothed gear).
