ABSTRACT:
A novel torque exchange coupling for transmitting rotational mechanical power is described. The coupling includes a torque receiving member, a torque transmitting member and means for conveying rotational mechanical power between the torque transmitting and receiving members. Typically, the torque receiving member is a housing, a cam or other suitable structure which has a surface comprising a circuitous track. The linear circumference of the track is undulant with respect to its axis of rotation. The torque transmitting member is any suitable rotatable mounting means such as a rotor which is positioned in a rotational power conveying relationship with the undulant track of the torque receiving member. Alternatively, the function of the torque receiving and torque transmitting members can be reversed. In this regard, the torque transmitting member is a housing, a cam or other suitable structure having a surface comprising a circuitous track, the linear circumference of which is undulant with respect to its axis of rotation. The torque receiving member is any rotatable mounting means such as a rotor which is positioned in a rotational power conveying relationship with the undulant track of the torque transmitting member. Where a rotor is employed as the rotatable mounting means, a preferred means for conveying power between the rotor and the undulant track is a variably extendible member attached to the rotor and typically comprises an arm which is pivotally attached to the rotor in a manner such that it is capable of making contact with the undulant track at any point in its linear course. This member is made variably extendible either by centrifugal force, centripetal force, or mechanical, electrical or hydraulic means. The novel coupling of this invention is highly efficient, is easily maintained, is not significantly affected in operation by the presence of heat, and is capable of operation without its components being in close alignment. It contains few moving parts and is strong, durable, and comparatively inexpensive to manufacture. It can be utilized as a clutch, as a transmission, in a braking application, or in practically any other application where a rotational coupling is indicated.
