Abstract
A power take-off includes an input mechanism having an input gear that is rotatably supported on a housing of the power take-off portion. The input mechanism also has a portion that extends outwardly through the opening provided through the mounting surface of the housing of the power take-off portion and that is adapted to extend within and be rotatably driven by the source of rotational energy. The power take-off further includes an output mechanism that is disposed within the housing and includes a driven gear that is rotatably driven by the input gear of the input mechanism. A rotational axis of the input gear and a rotational axis of the driven gear are misaligned so as to minimize the transmission of torque transients and other vibrations therethrough during operation.

A power take-off that is adapted to be secured to a mounting surface provided on a source of rotational energy, the power take-off comprising:
- a housing including a mounting surface that is adapted to be secured to a mounting surface provided on a source of rotational energy, the mounting surface of the housing of the power take-off portion having an opening therethrough;
- an input mechanism including an input gear that is rotatably supported on the housing of the power take-off portion and that has a portion that extends outwardly through the opening provided through the mounting surface of the housing of the power take-off portion and is adapted to extend within and be rotatably driven by a driving gear contained within the source of rotational energy;
- and
- an output mechanism disposed within the housing and including a driven gear that is rotatably driven by the input gear of the input mechanism,
- wherein a rotational axis of the input gear and a rotational axis of either the driving gear or the driven gear are misaligned so as to minimize the transmission of torque transients and other vibrations therethrough during operation.
An assembly of a power take-off and a source of rotational energy, the assembly comprising:
- a source of rotational energy including a mounting surface having an opening and a driving gear;
- and
- a power takeoff including (1) a housing including a mounting surface that secured to a mounting surface of the source of rotational energy, the mounting surface of the housing of the power take-off portion having an opening therethrough;
- (2) an input mechanism including an input gear that is rotatably supported on the housing of the power take-off portion and that has a portion that extends outwardly through the opening provided through the mounting surface of the housing of the power take-off portion and is adapted to extend within and be rotatably driven by the source of rotational energy;
- and (3) an output mechanism disposed within the housing and including a driven gear that is rotatably driven by the input gear of the input mechanism,
- wherein a rotational axis of the input gear and a rotational axis of either the driving gear and the driven gear are misaligned so as to minimize the transmission of torque transients and other vibrations therethrough during operation.
