ABSTRACT:
A multiple link drive belt for use in a Reeves-type drive has each link molded as an integral nylon plastic unit. Sloping edges of each link frictionally engage sloping flanges on driving and driven shafts to transmit power. Side surfaces extending between the sloping edges have recesses therein. Hinged members in each of these recesses engage hinged members of adjacent links. The hinges are held together by a pin extending through a bore in each hinge. Each link rotates about the axis of the pin so as to enable the belt to curve around the driving and driven shafts. The hinged members of adjacent links are longitudinally spaced from one another to provide a first gap along the axis of the pin. The diameter of the bores is greater than the diameter of the pin to provide a second gap in a direction perpendicular to the axis of the pin. The outer surfaces of the hinged member of one length are spaced from the recessed surface of the adjacent link when the links are pinned together to provide a third gap in a direction perpendicular to the axis of the pin. These three gaps make it possible for the drive belt to accommodate misalignment between the set of driving flanges and the set of driven flanges.
