Title:
TRANSMISSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/131141
Kind Code:
A1
Abstract:
Provided is a transmission device provided with a first transmission member of which the center axial line is a first axial line, an eccentric rotation member in which a main shaft part capable of rotating around the first axial line and an eccentric shaft part of which the center axial line is a second axial line are integrally linked, a plate-shaped second transmission member rotatably supported on the eccentric shaft part, a third transmission member of which the center axial line is the first axial line and which faces the second transmission member, a first speed change mechanism between the first and second transmission members, and a second speed change mechanism between the second and third transmission members, wherein second and third transmission grooves (22, 24) provided to both sides of the second transmission member (8) do not overlap each other as seen in a projected plane orthogonal to the second axial line (X2), and one of these transmission grooves is arranged so as to surround the other. It is thereby possible to minimize the decrease in thickness of the second transmission member between the second transmission groove of the first speed change mechanism and the bottom of the third transmission groove of the second speed change mechanism, to avoid strength insufficiency in the second transmission member without setting the thickness of the second transmission member to be especially thick, and to reduce the axial size of the device.
