P-306 FLUID POWER TRANSFER DEVICE ABSTRACT A fluid power transfer device includes a pair of rotors and vanes mounted for rotation in a hollow housing having an equatorial plane wherein conical faces of the rotors rollingly engage each other to form a line contact and wherein a hinge pin which hingedly connects the vanes is con- strained to rotate in the equatorial plane of the housing. A sun gear sector is connected to the side of each vane opposite the hinge pin. A ring gear sector is connected to the inner end of each output shaft to rotate therewith. A pinion planet gear connects each ring gear sector to each sun gear sector so that the pinion planet gears rock back and forth between their respective sectors as the vanes rock about the hinge pin. The pinion planet gears are elongated and confine the hinge pin to the equatorial plane. The pinion planet gears also act as splines to transfer torque. Each rotor includes a pair of rotor portions and an interconnecting outer band. The outer bands also have conical faces which rollingly engage each other to further form the line contact. The outer bands are slidably received within grooves formed on the inner surface of the housing. Each of the hinged vanes is received and extends towards its gear sector through a channel defined by its respective rotor portions. The conical faces of the rotors and the housing cooperate to define a working chamber which is divided into working compartments by the hinged vanes and the line contact. The rotors and the vanes transfer power between their respective shafts and an operating fluid introduced into one of the working compart- ments.
