Abstract:
A variable speed change gear comprising:an input shaft and an output shaft arranged coaxially with each other;a plurality of first rotating bodies which rotate integrally with the input shaft;a plurality of second rotating bodies having an equal mass, each of which engages with the first rotating body so as to be movable straight in the radial direction, and in which the rotational center can become eccentric in the radial direction with respect to the input shaft;a third rotating body in which the rotational center can become eccentric in the radial direction with respect to the input shaft together with the second rotating bodies;a one-way transmission member for transmitting a rotational force in a predetermined direction of the rotating body whose angular velocity is the highest or the lowest in the second rotating bodies to the third rotating body;a support member for supporting the second rotating bodies and the third rotating body so as to be rotatable and capable of being eccentric arbitrarily in the radial direction; anda transmission mechanism for transmitting a rotational force of the third rotating body to the output shaft,characterized in that the second rotating bodies are arranged so that the movement direction with respect to the first rotating body is shifted so as to form equal angles with each other with the input shaft being the center.
