  • Patent number: 7140456
    Abstract: A cutting auger has a main auger blade and a front subsidiary coaxial blade each having a drive core and a helical auger flight carried on the drive core for rotation about a longitudinal axis of the drive core with a cutting edge at an axial end face of the auger flight, such that when rotated the cutting edge cuts a hole equal in diameter to the helical flight and the helical flight carries the cut material away from the cutting edge. The second auger blade having a smaller diameter than the first, is shorter than the first and is arranged with the helical turns thereof in opposed angular direction. A planetary drive system is arranged to rotate the first and second cutting augers in opposed direction with the first driven at a slower angular velocity than the second so as to balance the torque.

  • Patent number: 6796922
    Abstract: A planetary gear 5 is contacted at its at least one tooth of all its teeth 51n with an end edge 23d facing an inner releasing part 23c of an inner peripheral surface of a receiving hole 23a irrespective of a rotational position of the planetary gear 5. By doing so, the planetary gear 5 is prevented from moving in the radial direction. As a result, the planetary gear 5 can be prevented from vibrating in the radial direction. Thus, vibrations of a planetary gear apparatus can be reduced, and the planetary gear and a carrier can be reduced in damage.

  • Patent number: 6164812
    Abstract: The electric food processor has a housing in which there is disposed an electric motor with a motor shaft. The motor shaft, via a gear mechanism, drives three or more concentric output drives at different rotational speeds. The common axis of rotation of the output drives is spaced a distance from the motor shaft. Working tools are selectively coupled to the output drives and the working tools rotate in a working container which is placed on the housing. In order to expand the possible uses of the food processor, the fastest output drive rotates at a speed that is suitable for a mixing tool, and the gear mechanism has at least two sets of input gear teeth that are rotatably mounted independently of each other, so that the fastest output drive can be driven out of direct engagement with the slower output drives.

  • Patent number: 6122984
    Abstract: A phase control mechanism controls phase relationship between two shafts. The phase control mechanism may be used to control various mechanical devices such as the pitch of propellers of aircraft and boats, the pitch of power producing windmills, opening and closing lathe and drill chucks and controlling the eccentricity of some forms of continuously variable transmissions when the mechanisms are not only stationary but also in normal operational motion. The phase control mechanism includes first gears 3,4; 56,64 coupled to the output shafts which are to be phase controlled. A transfer gear 5; 16,17; 52,54 is provided for rotation or operation independent of the input and is coupled to the first gears 3,4; 56,64 to allow rotary motion to be transferred between the first gear members and a phase adjuster 10; 80 causes the first gears 3,4; 56,64 to advance or regress relative to one another to change the phase relationship between the outputs.

  • Patent number: 5711740
    Abstract: The present invention is directed to a two-speed gear reduction unit and a shift mechanism for establishing two distinct speed ratio drive connections between an input member and an output member. More specifically, the shift mechanism includes a clutch apparatus for stopping relative rotation between the input and output members prior to shifting the gear reduction unit from its neutral operating state into either of its high-range or low-range operating states. Thus, the present invention is adapted for use in the transfer case of a four-wheel drive vehicle for shifting between four-wheel high-range and low-range drive modes.

  • Patent number: 5674147
    Abstract: A sub-transmission of a transfer unit includes a shift sleeve that moves to a neutral position N where it does not engage with a high-speed gear set to an input shaft or a low-speed gear set to a deceleration system, and thereafter engages with the high- or low-speed gear to transfer the driving force of the input shaft to an output shaft in the form of a high-speed or low-speed driving force. The output shaft has an outer periphery provided with an annular friction member in contact with the input shaft, for reducing the rotational speed of the input shaft, and thereby decreasing gear screeches during a changeover between low- and high-speed positions, even if a free-running torque is transferred to the input shaft from a hydrodynamic automatic transmission.

    Abstract: An improved transmission for transferring torque. First and second gears are each configured for integral, rigid attachment to first and second torque-bearing bodies, respectively. A third gears is disposed in simultaneous meshing engagement with the first and second gears such that said first and second gears are disposed in substantial co-axial orientation. The gears are configured such that rotation of a first of the three gears relative to a second of the three gears causes rotation of the remaining third gear via the various meshing engagements to thereby accomplish a transfer of torque from the first gear to the third gear.

  • Patent number: 5540629
    Abstract: A reversible hand operated rotary power tool contains an internal mechanism for reducing the reaction torque that would otherwise be exhibited directly upon the housing, and hence imposed upon the hand of the operator. The mechanism is bidirectional, and reduces reaction torque to the same extent whether the tool is being operated in a forward direction or in a reverse direction. The mechanism includes a planetary differential mechanism having an input driven from a powered rotor, one separate output that is drivingly coupled to an output shaft, and another separate output that is drivingly coupled to an offset shaft that is laterally offset from the axis of the powered rotor. A lever system is employed to inhibit rotation of the offset shaft in either direction relative to the housing and thereby reduce reaction torque exhibited on the housing.
