Abstract
Abstract A drive train for ships with plural engines, plural input and common output reduction gearing coupled to the propeller shaft. Resilient shift clutches couple each engine to the reduction gear. Each reduction gear input is received by a hollow shaft and coupled to the input of the respective shift clutch. The hollow shaft is geared to an auxiliary shaft for driving auxiliary equipment.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
211 words
Drive for ships having at least one drive engine, propeller shaft and reduction gear, disposed in a housing and having a pinion shaft with pinion journalled in the housing and meshing with a gear wheel connected to the propeller shaft, the combination comprising: a resilient shift clutch having input and output parts, and disposed between engine and reduction gear, the input part being concentrically disposed to the output part and to the pinion shaft, further connected to the drive output of the engine, the output part of the clutch connected to the pinion shaft of the reduction gear; a hollow shaft, receiving and traversed by the pinion shaft, but being journalled in the housing independently from the pinion shaft and from the shift clutch, and carrying a gear wheel; a coupling having input and output, the input thereof being concentrical to the hollow shaft and axially connected directly to and driven by the input part of the shift clutch, the output of the coupling connected to and driving the hollow shaft; and an auxiliary shaft journalled in the housing of the reduction gear and having a pinion, meshing with the gear wheel on the hollow shaft so that the auxiliary shaft is driven via said clutch, input coupling and hollow shaft.
Claim 2
Dependent Claim
211 words
Drive for ships having at least one drive engine, propeller shaft and reduction gear, disposed in a housing and having a pinion shaft with pinion journalled in the housing and meshing with a gear wheel connected to the propeller shaft, the combination comprising: a resilient shift clutch having input and output parts, and disposed between engine and reduction gear, the input part being concentrically disposed to the output part and to the pinion shaft, further connected to the drive output of the engine, the output part of the clutch connected to the pinion shaft of the reduction gear; a hollow shaft, receiving and traversed by the pinion shaft, but being journalled in the housing independently from the pinion shaft and from the shift clutch, and carrying a gear wheel; a coupling having input and output, the input thereof being concentrical to the hollow shaft and axially connected directly to and driven by the input part of the shift clutch, the output of the coupling connected to and driving the hollow shaft; and an auxiliary shaft journalled in the housing of the reduction gear and having a pinion, meshing with the gear wheel on the hollow shaft so that the auxiliary shaft is driven via said clutch, input coupling and hollow shaft.
Claim 3
Dependent Claim
11 words
Drive as in claim 1, the coupling being a resilient coupling.
Claim 4
Dependent Claim
11 words
Drive as in claim 1, the coupling being a jaw coupling.
Claim 5
Dependent Claim
19 words
Drive as in claim 1, the hollow shaft journalled by two bearings in the housing of the reduction gear.
Claim 6
Dependent Claim
19 words
Drive as in claim 1, the pinion shaft journalled by two bearings in the housing of the reduction gear.
Claim 7
Dependent Claim
73 words
Drive as in claim 1, there being a second engine, a second shift clutch for driving a second pinion shaft, a second hollow shaft on the second pinion shaft, a second auxiliary shaft geared to the second hollow shaft, and a second coupling for coupling the input of the second clutch also to the second hollow shaft, the two shift clutches operating selectively, the second pinion shaft likewise coupled to the propeller shaft.
Claim 8
Dependent Claim
169 words
Drive for ships having at least one drive engine, propeller shaft and reduction gear disposed in a housing, the combination comprising: a pinion shaft journalled in the housing and geared to the propeller shaft; a shift clutch having (a) a rotatable output part concentrical on the pinion shaft, (b) an operable shift element coupled by resilient elements to the output part, (c) a rotatable input part concentrical to the output part selectively connectable to the shift element, and having first axial end flange coupled to the engine and second axial end flange extending in opposite direction along the axis of the pinion shaft; a coupling having input axially flanged to the second axial end flange of the clutch and rotating therewith, further having output coaxial therewith; a hollow shaft telescoped in the pinion shaft and being journalled in the housing independently from the pinion shaft by means of two bearings, the hollow shaft axially coupled to the coupling for rotation therewith; and auxiliary equipment geared to the hollow shaft.
Claim 9
Dependent Claim
