    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.

  • Publication number: 20110306456
    Abstract: A dual clutch transmission having improved packaging and reduced spin losses provides a five, six or seven forward speeds and reverse. An input shaft includes two or three gears which are in constant mesh with and directly drive associated gears freely disposed on a pair of parallel quills. Synchronizer clutches associated with these driven gears selectively synchronize and connect the gears to the quills which are, in turn, connected to countershafts residing within the quills. Additional gears which are in constant mesh with a pair of ring (output) gears are synchronized and connected to the countershafts by additional synchronizer clutches. Activation of two synchronizer clutches and one input clutch provides a selected gear ratio and transfers torque from the input shaft to the output ring gears.

  • Patent number: 7942079
    Abstract: A turbine engine power generation system includes a gearbox that receives rotational drive from a low spool through an input gear, in one example. The gearbox includes first and second clutches that are coupled to an input shaft of an auxiliary component, such as a generator. First and second output gears are driven at different rotational speeds by the input gear and respectively associated with the first and second clutches. An actuator selectively engages at least one of the first and second clutches to select between first and second rotational speeds in response to a command from a controller.

  • Patent number: 7882691
    Abstract: A turbine engine includes low and high pressure spools. A high power take-off shaft is coupled to the high spool. An auxiliary component, such as a generator, is configured to be driven by the high power take-off shaft at a first speed. The low spool, in part, drives the auxiliary component, for example, by interconnecting the high power take-off shaft to a lower power take-off shaft through a speed summing gearbox. The gearbox drives the auxiliary component and increases the rotational speed of the auxiliary component from the first speed to the second speed. The low power take-off shaft also drives another generator, in one example. The turbine engine can be started by the low pressure generator, for example, in response to a command from a controller, which transforms the generator into a starter motor.

    Abstract: An automated group transmission having a multi-stage main transmission (HG), a splitter group (VG) connected upstream from the main transmission (HG) and a two-stage range-change group (BG) connected downstream of the main transmission (HG), such that the splitter group (VG) is connected, via a controllable separator clutch, to a drive motor. The main transmission (HG) and the range-change group (BG) are of either a synchronized or an unsynchronized design and the shifting clutches of two respective transmission ratio steps, in at least one of the partial-transmissions (VG, HG, BG), are respectively combined in a common shifting packet with two shift positions and a neutral position. To speed up most range shifts, it is provided that in the main transmission (HG) the shifting clutches associated with the lowest transmission ratio step (G1) and with the highest transmission ratio step (G4 or G3) are combined in a common shifting packet (S1/4 or S1/3).

  • Publication number: 20100139453
    Abstract: A power transmission switching mechanism for office machine. The power transmission switching mechanism has simple structure and enables the office machine to commonly use a motor to execute scanning and printing works. The power transmission switching mechanism includes a rotary shaft, a drive gear mounted on the rotary shaft, an actuator reciprocally movable on the rotary shaft and a driving gear for transmitting power of a motor to the drive gear. The drive gear has an spline. The actuator can be selectively moved forward or backward to make the spline disengaged from a first gear mounted on the rotary shaft or engaged with the first gear. When the spline is disengaged from the first gear, the power of the motor is transmitted to a scanning module. When the spline is engaged with the first gear, the power of the motor is transmitted to the rotary shaft for printing work.

    Abstract: In a twin clutch transmission, a first main shaft transfers rotation power of a crankshaft that is provided in parallel, input via a first clutch, to a drive shaft via an odd-numbered transmission gear mechanism. A second main shaft transfers rotation power of the crankshaft that is provided in parallel, input via a second clutch, to the drive shaft via an even-numbered transmission gear mechanism. In a first power transfer path running from the crankshaft to the drive shaft via the first clutch and a second power transfer path running from the crankshaft to the drive shaft via the second clutch, back torque limiters are provided that, when reverse torque operates in a direction opposite the direction for acceleration of a rear wheel, limits transfer of the reverse torque.
