Abstract: A gearing with duplex floating toothed portions for transmission between either two parallel shafts or two intersecting shafts comprising two meshing gears(12) and (14) one gears (14) having coaxially disposed toothed portions (16) and (18) interacting with component (20) by spiral joints (22) and (24) different characteristics and an arrangement limitative divided spiral motions of toothed portions (!6) and (18) relatively component (20) by parting plane “A” and arresting device (26). Both toothed portions (16) and (18) of gear (14) and meshing gear (12) have mating teeth whereby both toothed portions (16) and (18) are coupled positively with component (20). Even distribution of applied force between toothed portions (16) and (18) or elimination of the free angular displacement of the gear (12) and (14) with respect to each other within backlash are provided by choice of characteristics of spiral joints (22) and (24).
