Claims

[Scope of utility model registration request]

A ring gear, a sun gear that rotates coaxially with the ring gear, a carrier that rotatably supports a planetary gear that meshes with the ring gear and the sun gear and rotates coaxially with the ring gear;
an engine crankshaft that drives and rotates one of the ring gear and the sun gear; an engine auxiliary machine that is driven and rotated by the output from the carrier; and any two of the ring gear, the sun gear, and the carrier. A one-way clutch that is provided on the other of the ring gear and the sun gear and that only allows rotation in the same direction as the other crankshaft and prevents rotation in the opposite direction. When the rotational speed of the crankshaft is below a predetermined value, the two elements are coupled by the coupling means and the rotational speed of one of the elements is transmitted to the carrier without changing the speed, and when the rotational speed of the crankshaft exceeds the predetermined value. 2 above by the coupling means.
In a variable speed auxiliary drive device in which the rotation speed of one of the elements is reduced and transmitted to the carrier by disengaging the elements and preventing rotation in the opposite direction with a one-way clutch, the rotation speed of the ring gear or sun gear When the rotation speed of the ring gear or sun gear is reduced to 1/i of the rotation speed of the crankshaft, and the rotation speed of the ring gear or sun gear is reduced to 1/i, the rotation speed of the engine auxiliary equipment driven by the carrier is calculated as follows: A variable speed accessory drive device characterized in that the speed is increased to i times the rotational speed of an engine accessory driven by a carrier when the engine accessory is rotated at the same rotational speed.
