Abstract
An engine driven shaft is connected to an input gear of the transmission which, in turn, is geared to a power branching cascade, providing either for axial branching first followed by lateral branching or a reverse sequence of branching, obtaining in either case four outputs provided by pinions which mesh in pairs two large spur gears for re-combining all branches. These large spur gears are on a common shaft which is the transmission output.
Claims13
A transmission for a ship's drive system having a first, engine-driven shaft as input of the transmission and a second shaft as output thereof, comprising:
- a pair of relatively large diameter spur gears, drivingly connected to the second shaft for driving the second shaft;
- first and second pairs of pinions, the pinions of each pair being coaxially arranged and respectively meshing the spur gears of the pair so that each spur gear meshes with two of the pinions;
- first gear means connected to be driven by the first shaft;
- and
- second gear means which includes cascaded transmission means (a) and (b), one of the transmission means (a) and (b) providing for axial power branching, the other one being gear means providing lateral power branching, the transmission means (b) including four driven shafts respectively connected to the pinions of said first and second pairs, the transmission means (a) including gear means drivingly connected to and gearingly meshing with the first gear means.
Transmission as in claim 4, the pinions being hollow and respectively traversed by said shafts, there being four clutch means for respectively connecting the shaft ends to the pinions.
A transmission for a ship's drive system having a first, engine-driven shaft as input of the transmission and a second shaft as output thereof, comprising:
- a first gear, drivingly connected to the first shaft and being driven by the shaft;
- first means geared to the first gear to obtain lateral power branching, including two gears driven by the first gear:
- second and third means respectively drivingly connected to the two gears, each of the second and third means providing for axial power-branching resulting in four driven outputs, said four driven outputs including respectively four pinions, of which two rotate in a common plane and the other two rotate in another common plane;
- and
- two large spur gears on the output shaft and respectively disposed in said common planes for driving the output shafts, each of the large spur gears meshing with respective two of the four pinions so that the four pinions drive the spur gears in pairs.
A transmission for a ship's drive system having a first engine drive shaft as input of the transmission and a second shaft as output thereof, comprising:
- a first gear drivingly connected to the first shaft and being driven by the first shaft;
- a shaft for the first gear and extending axially from the first gear;
- second and third gears on the shaft to obtain axial power branching;
- first and second means respectively geared to the second and third gears and providing for lateral power branching, there being four driven outputs accordingly, said four driven outputs including respectively four pinions, of which two rotate in a common plane and the remaining two rotate in another common plane;
- and
- two large spur gears on the output shaft for driving the output shafts, each of the large spur gears meshing with respective two of the four pinions which rotate in a common plane so that the four pinions drive the spur gears in pairs.
