Abstract
Official abstract text for this publication.
In a wave gear device, similarity-curve tooth profiles BC and AC are adopted as addendum tooth profile shapes for gears, the tooth profiles being derived from a movement trajectory M 1 of an external tooth of a flexible externally toothed gear having zero deviation (κ=1), in relation to an internal tooth at a main cross-section. Profile shifting is performed on the external tooth along the tooth trace for a movement trajectory M 3 of the external tooth to share a bottom portion with the movement trajectory M 1 at the main cross-section from the main cross-section to an inner edge. Profile shifting is performed on the external tooth along the tooth trace for the movement trajectory of the straight-line tooth-profile portion of the external tooth from the main cross-section to the outer edge to be consistent with the movement trajectory of the straight-line tooth-profile portion of the main cross-section.
First claim
Opening claim text (preview).
The invention claimed is: 1. A wave gear device having a three-dimensional contact tooth profile, comprising: a rigid internally toothed gear; a flexible externally toothed gear disposed coaxially on an inner side of the internal gear; and a wave generator fitted into an inner side of the external gear, wherein the flexible externally toothed gear has a flexible cylindrical barrel part, a diaphragm extending in a radial direction from a rear edge of the cylindrical barrel pa…
