Definitions
- the present invention relates to a propulsion arrangement for a marine vessel, which propulsion arrangement comprises an internal combustion engine, a shaft arrangement and a steerable thruster unit, whereby the marine vessel further comprises an electric generator or a combined electric generator and motor in connection with the propulsion arrangement.
- Conventional marine vessels with the above type of propulsion arrangements and thereto related machinery may be provided with an additional device, particularly an electric generator or a combined electric generator and motor for generating e.g. hotel load electric power or for improving flexibility and redundancy in propulsion power.
- an electric generator or a combined electric generator and motor for generating e.g. hotel load electric power or for improving flexibility and redundancy in propulsion power.
- Such devices are often called shaft generators which, depending upon their location, may be used only as an electric generator or as an electric generator and an electric motor in combination.
- an electric generator may be connected to the free end of the internal combustion engine, i.e. opposite the main shaft of the internal combustion engine, whereby no extra gear is necessary.
- This solution requires surplus space at the free end of the engine.
- a generator can not provide power through the engine, i.e. it can not function as an electric motor.
- This type of single function arrangement is usually called a PTO (Power Take Off) arrangement.
- a combined electric generator and motor may be connected to the main shaft of the internal combustion engine by means of a so-called step-up gear.
- the step-up gear necessitates additional equipment with thereto related costs.
- the step-up gear also causes transmission losses.
- this known solution requires sufficient and suitable space along the main shaft.
- This type of dual function arrangement is usually called a PTO/PTI (Power Take Off / Power Take In) arrangement.
- the additional device should be clearly understood as having three separate functions, i.e. firstly the additional device may installed to be used as an electric generator (PTO), secondly to be used mainly as an electric motor (PTI), and thirdly to be used as a combined electric generator and motor (PTO/PTI), whereby it may coupled so that it in a first mode functions as an electric generator and in a second mode as an electric motor.
- PTO electric generator
- PTI electric motor
- PTO/PTI combined electric generator and motor
- the object of the present invention is to achieve a propulsion arrangement for a marine vessel by which the above disadvantages are avoided and which provides a multifunctional operation by way of a simplified arrangement.
- This object is attained by a propulsion arrangement according to claim 1.
- the basic idea of the invention is to provide a propulsion system that includes an electric generator or a combined electric generator and motor and that may be directly employed also to the steerable thruster unit.
- the shaft arrangement comprises a main shaft extending from the internal combustion engine to a first angle gear and a drive shaft extending from the first angle gear to a second angle gear in the steerable thruster unit.
- the electric generator or the combined electric generator and motor is connected to the drive shaft of the shaft arrangement, after the main shaft and the first angle gear connected thereto.
- the main shaft is thus free of any installations relating to the electric generator or the combined electric generator and motor.
- the electric generator is directly coupled to the drive shaft, above the first angle gear with respect to the steerable thruster unit. This eliminates any space requirements around the internal combustion engine or the main shaft.
- the electric generator is directly coupled to the drive shaft, above the first angle gear with respect to the thruster unit, and a coupling is provided on the drive shaft, between the electric generator and the first angle gear.
- this allows the internal combustion engine to drive the steerable thruster unit without turning the generator.
- the electric generator is directly coupled to the drive shaft, directly above the first angle gear with respect to the steerable thruster unit, and a coupling is provided on the drive shaft between the first angle gear and the second angle gear.
- this allows the internal combustion engine to turn the electric generator without driving the steerable thruster unit.
- the combined electric generator and motor is directly coupled to the drive shaft, above the first angle gear with respect to the steerable thruster unit, and a coupling is provided on the main shaft, between the internal combustion engine and the first angle gear. This allows the combined electric generator and motor to drive the steerable thruster unit without turning the internal combustion engine.
- an auxiliary coupling may be provided between the combined electric generator and motor and the first angle gear. This additionally allows the internal combustion engine to drive the steerable thruster unit without turning the combined electric generator and motor.
- an auxiliary coupling may be provided between the first angle gear and the second angle gear. This additionally allows the internal combustion engine to turn the combined electric generator and motor without driving the steerable thruster unit.
- the combined electric generator and motor may also be provided with a shaft section and a gear transmission, whereby it is connected to the drive shaft through the first angle gear by means of the gear transmission.
- the combined electric generator and motor is then preferably arranged on either side of or aft of the steerable thruster unit or the drive shaft, substantially in the plane of the main shaft and the first angle gear.
- the main shaft is substantially horizontal or generally horizontally oriented, the drive shaft substantially vertical or generally vertically oriented, and the propeller shaft of the steerable thruster substantially horizontal or generally horizontally oriented, whereby transmission is provided through the first angle gear and the second angle gear as well as the angle transmission, when appropriate.
- the main shaft may as well be inclined.
- the coupling and auxiliary couplings are preferably so-called disconnecting couplings or flexible couplings and may be deployed according to the desired operational mode.

- the second angle gear 34 connects the drive shaft 33 to a propeller shaft 41, with a propeller 42, in the steerable thruster unit 4.
- Power is thus transmitted from the internal combustion engine 2 by means of the substantially horizontal or generally horizontally oriented main shaft 31 to the first angle gear 32, from the first angle gear 32 to the substantially vertical or generally vertically oriented drive shaft 33, which drives the second angle gear 34, which in turn drives the substantially horizontal or generally vertically oriented propeller shaft 41 with the propeller 42.
- An arrangement of this type with steerable thruster units 4 is generally called a Z- drive due to its configuration.
- the marine vessel 1 is provided with an electric generator 51 which is directly coupled to the drive shaft 33 and arranged directly above the first angle gear 32 with respect to the steerable thruster unit 4.
- the electric generator 51 always turns when the propeller 42 is turning, i.e. when the steerable thruster unit 4 is driven by the internal combustion engine 2.
- the electric generator 51 is coupled to the drive shaft 33 after the main shaft 31 and the first angle gear 32 connected thereto in the direction of transmission of power from the internal combustion engine to the propeller 42.

- An additional auxiliary coupling 62 may be provided on the drive shaft 33, between the combined electric generator and motor 52 and the first angle gear 32. This auxiliary coupling 62 allows the internal combustion engine 2 to drive the steerable thruster unit 4, i.e. the propeller 42, without turning the combined electric generator and motor 52.
- the combined electric generator and motor 52 is coupled to the drive shaft 33 after the main shaft 31 and the first angle gear 32 connected thereto in the direction of transmission of power from the internal combustion engine to the propeller 42. Thereby the main shaft 31 is free from any connections with the combined electric generator and motor 52, thus providing free space around the main shaft 31.

- the combined electric generator and motor 52 is situated aft of the steerable thruster unit 4, or the drive shaft 33, i.e. opposite the main shaft 31 substantially aligned or in the same plane as the main shaft 31.
- the combined electric generator and motor 52 also may be on either side of the steerable thruster unit 4, or in any in between position around the first angle gear 32, and that it need not be in the same plane as the main shaft 31.
