  • Gear assembly
    Patent number: 4719813
    Abstract: A gear assembly for high-speed transmission between either two parallel shafts or two intersecting shafts comprising two meshing gears, one mounted to a drive shaft and the other mounted to a driven shaft, each of the gears having coaxially disposed first and second toothed portions which differ from each other in that the teeth of the first toothed portion are cut at a first inclination angle and the teeth of the second toothed portion are cut at a second inclination angle different from the first inclination angle. One of the meshing gears is fixed to its shaft so as to be non-displaceable axially, while the other is mounted so as to be axially displaceable with respect to the fixed gear.
    Type: Grant
