involute gear coupling with a bevel gear root

摘要

The present invention relates to a gear coupling using a bevel gear, particularly by the coupling of the gear In the coupling gear for transmitting power by connecting the first rotation axis and the second axis of rotation, consists of a cylindrical side is coupled to the first rotation axis, along the other side of the internal circumference bevel gear having a tooth profile formed obliquely inwardly involute internal hub; Being made of a cylindrical spline formed on the outer peripheral side is coupled with the second rotation axis, along the other side of the circumscribed circumference bevel gear having an involute tooth profile circumscribed is inclined outwardly to be engaged with the internal bevel gear hub; The internal hub first pivot holder rotatably coupled by a first thrust bearing therein; Said external hub second pivot holder rotatably coupled by a second thrust bearing and the first pivot holder and the hinged therein; And the inner peripheral surface forms a cylindrical shape in the axial direction by a spline groove is formed, and the external hub and the spline spacer to guide the axial flow is placed between the second rotary shaft; consists of, a bevel gear circumscribed with the internal bevel gear backlash and being characterized in that the coupling for transmitting power in a state to form a first rotation axis and the second axis of rotation, forming a chukgak, this structure is not more excellent power density, and do not have a locking phenomenon also occurs bending moment transmission error rate not caught between the teeth, as well as due to the vibration of the slip is less tooth reduction gear lifetime escape to the outside of debris hit a long, because the centrifugal force.
