More Information
Summary:The invention provides a method for improving the contact ratio of internal gearing cycloidal gears. The method includes the following steps: during intermeshing engaging-out between an external gear and an internal gear, setting the diameter of the engaging circle during engaging-out to be a value between that of the pitch circle of the external gear and that of the pitch circle of the internal gear, so as to ensure that the tooth crest of the external gear is meshed with that of the internal gear; during intermeshing engaging-in between the external gear and the internal gear, setting the diameter of the engaging circle during engaging-in to be the difference value between that of the pitch circle of the internal gear and that of the engaging circle during engaging-out, so as to ensure that the tooth root of the external gear is meshed with the tooth crest of the internal gear.
