  • Patent number: 8506437
    Abstract: There is disclosed a mechanical two-speed drive system/gearbox for household appliances such as a blender or food processor. The gearbox comprises a motor, a motor shaft, a drive-outlet, and the installation of one-way bearings in suitable places in the gear-train. The drive-outlet can be driven at two different speeds in the same rotational direction. By operating the motor in the clockwise direction and counter-clockwise direction, a change in the drive-outlet rpm is achieved. When operating in the hi-speed mode, the drive-outlet is directly driven by the motor. When operating in the lo-speed mode, the drive-outlet is driven via the gear-train, with a resulting increase in torque. This gearbox is simple to construct, and operable without expensive control electronics. In particular applications with electronic motor speed and directional control, a much broader and useable drive-outlet speed range is achieved.

  • Patent number: 6117036
    Abstract: A split planetary gear assembly having a pair of helical gearsets. The first helical gearset includes a first sun gear, a first ring gear, and a set of first planet gears meshed with the first sun gear and the first ring gear. The second helical gearset includes a second sun gear, a second ring gear, and a set of second planet gears meshed with the second sun gear and the second ring gear. The components of the second helical gearset have the same number of teeth, helix angle, and tooth pitch as the components of the first helical gearset with the exceptions that their angular helix orientation (i.e., left-hand/right-hand) is reversed and they are circumferentially indexed by one-half tooth pitch. In addition, the first and second planet gears are arranged in paired sets and supported on a common pinion shaft which, in turn, is fixed to a planet carrier. The second sun gear is splined for rotation with and limited axial movement relative to the first sun gear.

  • Patent number: 5967934
    Abstract: A planetary transmission has a plurality of axially arranged planetary gear units each including sun gears, planet gears in mesh with the sun gears, and ring gears coaxial with the sun gears and in mesh with the planet gears, the arrangement being such that one of the ring gears in each planetary gear unit is blocked from being rotated while the other ring gear is made rotatable for allowing an output to be taken out, upon which the ring gear of which rotation is blocked is made selectable for changing over the reduction ratio, and a smooth bilateral change-over of speed change can be realized by executing the change-over between rotation-blocked and rotation-free states of the ring gear by means of a one-way clutch capable of releasing the rotation blocking.

  • Patent number: 5855530
    Abstract: The present invention relates to a speed-changing transmission hub for a bicycle comprising: a central shaft; a controlling device; a planetary gear system, which comprises a planet gear holder, holding several planet gears; a second ring gear; a first ring gear; and two sun gears. Variations of speed are realized by separately fixing the sun gears of different diameters. There is no switching of input and no reversal of the rotation of the sun gears. The sun gears only need to be controlled by a one-way clutch guided by the controlling device, which is mounted on the central shaft. Thereby the arrangement is simplified and its weight is reduced.

  • Patent number: 5787766
    Abstract: The invention relates to a torque-splitting gear having a driving shaft and axis-parallel driven pinion shafts running in the same sense which are coupled with each other by toothed wheels. The gear is to be designed in such a way that it can be built up in different dimensions and for different powers while maintaining a great number of its components without change. The coupling between the driving shaft and the main driving toothed wheels is realized by a herringbone gearing. For transmitting great torques the main driving toothed wheels and the pinions on the driven pinion shafts are additionally coupled with each other via intermediate pinions and hollow wheels.
