ABSTRACT:
A synchronized drive and cable handling system is disclosed for a rotational element, such as a rotational gantry of a tomographic scanning machine, upon which element are carried load devices to which a medium, such as oil or electricity, is required to be supplied through the cables. A pair of spaced-apart sets of idler pulleys are disposed to either side of the rotational element with a cable being wound about the respective pulley sets to form an elongated loop, one end of each respective cable being attached to a load device which is disposed on the rotational element. One pulley set of each pair of sets is disposed about a translatable axis, the position of which is controlled by a lead screw drive to vary the distance between the pair of pulley sets and to thus vary the amount of cable which is played-out and taken-in therefrom. A single drive means is provided for effecting rotation of the rotational element and the load devices carried thereon, and for also simultaneously effecting movement of the translatable pulley axes of the cable handling system so that at each side of the rotational element, measured lengths of cable are played-out and taken-in with respect to the rotational element and in synchronism with the rotation of the rotational element, whereby the cables are smoothly and reliably fed during operation, and whereby the inertia of the rotational element remains relatively constant.
