Abstract:
1. A transmission arrangement for translating movement of a plurality of prime motors into a rotational movement for rotating a shaft in a rotational direction, the transmission arrangement comprising: (a) a first prime motor arrangement comprising a first prime motor, a first gear wheel, a first bevel gear wheel and a first freewheel bearing, the first gear wheel being engaged with the first prime motor and being integrally formed with the first bevel gear wheel to form a first unit, the first unit being concentrically attached to the shaft via the first freewheel bearing with the first freewheel bearing engaging the shaft only when the first gear wheel rotates in the rotational direction such that the first gear wheel can translate a movement of the first prime motor into a rotational movement of the shaft if the first gear wheel is rotating in the rotational direction but not if the first gear wheel is rotating in a direction opposite to the rotational direction; (b) a second prime motor arrangement comprising a second prime motor, a second gear wheel, a second bevel gear wheel and a second freewheel bearing, the second gear wheel being engaged with the second prime motor and being integrally formed with the second bevel gear wheel to form a second unit, the second unit being concentrically attached to the shaft via the second freewheel bearing with the second freewheel bearing engaging the shaft only when the second gear wheel rotates in the rotational direction such that the second gear wheel can translate a movement of the second prime motor into a rotational movement of the shaft if the second gear wheel is rotating in the rotational direction but not if the second gear wheel is rotating in a direction opposite to the rotational direction; and (c) means for engaging the respective first and second bevel gear wheels to cause the second unit comprising the second bevel gear wheel and second gear wheel to rotate in a direction opposite to the rotational direction when the first gear wheel is rotating in the rotational direction and to cause the first unit comprising the first bevel gear wheel and first gear wheel to rotate in a direction opposite to the rotational direction when the second gear wheel is rotating in the rotational direction.
