Definitions

  • the present invention relates to a ship propulsion for controlling and propelling a ship according to the preamble of claim 1.
  • pod drives for ships which are also referred to as swivel ship propulsion or Rudderpropeller.
  • Such marine propulsion for simultaneously controlling and propelling a ship have a gear unit inside the fuselage and a control unit below the fuselage in the water.
  • At least one propeller is rotatably mounted on the control unit and is driven by a propeller shaft, which is rotatably mounted in the interior of the control housing.
  • the control unit is pivotable for controlling the ship about its vertical axis, which is substantially parallel to the vertical axis of the ship.
  • the transmission unit is coupled to a drive motor via an output shaft.
  • the drive motor is arranged like the gear unit within the hull.
  • an angle drive is arranged to transmit the drive power down to the propeller shaft.
  • gear units In the angle drive or in an optional translation stage a speed or torque conversion and a reversal of the shaft rotation are possible.
  • Prior art gear units have only one shaft connection, which is connected to the drive shaft or the motor. If a further drive machine is intended to drive the propeller, as is required, for example, in a hybrid drive in which an electric motor is additionally to be provided as an alternative drive machine, the gear unit requires a so-called auxiliary drive for this purpose.
  • the advantage of the electric motor in a hybrid drive is its possible use in operating areas in which the noise and / or exhaust emission is limited, or in low speed ranges such as _ when driving slowly or when maneuvering for loading or unloading.
  • the DE 69933288 T2 shows a pivoting ship propulsion, but at which no drive by an alternative drive machine is possible.
  • a new gear unit must be constructed or the existing gear unit redesigned and rebuilt.
  • a hybridization of an existing marine propulsion of the type described is thus required only with considerable effort.
  • the EP 1259423 B1 shows a twin-engine marine propulsion system.
  • a marine gearbox has two input shafts for each drive machine.
  • the input shafts can be coupled to the propeller shaft by means of several clutches or can drive the propeller shaft together.
  • both input shafts are present in the transmission, ie the transmission is more complex than it is required, which is noticeable, for example, in increased costs and assembly costs and weight.
  • the transmission is designed for a drive of only one drive motor, the second, unused, input shaft can be dispensed with during assembly of the transmission.
  • the object underlying the invention is to provide a designed as a rudder propeller ship propulsion, the transmission unit is easily convertible to be drivable by at least one other drive machine.
  • a pivotable ship propulsion which is designed as a rudder propeller, comprises a gear unit within the hull and a control unit outside the hull.
  • an input shaft of a drive device that can be driven by a drive machine is arranged rotatably about a first rotation axis at a connection point.
  • a coupled to the input shaft output shaft is rotatably disposed about a second axis of rotation.
  • the axes of rotation are neither parallel nor concentric with each other.
  • at least one further connection point is provided on the transmission unit, to which a further drive device drivable by a further drive machine can be arranged to drive the output shaft.
  • a drive device in each case comprises an input shaft with means for adaptation to a drive machine and bearing means for the rotatable mounting of the input shaft.
  • an input shaft of a second drive device is arranged coaxially to the output shaft and rotatably connected thereto, whereby the output shaft is supported by means of the bearing means of the second drive device. Since the output shaft is also in a prior art pivotable marine propulsion, i. without the possibility of a drive by an alternative drive machine, must be stored, the additional cost of means for adaptation to a prime mover is very low, because the auxiliary drive and output shaft require only a common camp. Thus, the creation of an option for a drive by an additional drive machine means only a very small construction effort.
  • the input shaft of the first drive device is coupled to the output shaft by means of an angle drive comprising at least two bevel gears.
  • the input shaft of another drive device is coupled by means of an angle drive with the output shaft.
  • an input shaft of the further drive device as well as the input shaft of the first drive device is rotatable about the first axis of rotation.
  • the gear unit comprises a gear housing in which a plurality of inner contours are formed for receiving a respective drive device.
  • the outer diameter of a bevel gear of a drive device is smaller than the inner diameter of the drive device associated inner contour of the transmission housing.
  • bearings for supporting the input shaft of the respective drive device are arranged in a bearing bush, wherein the bearing bush can be arranged in the respective inner contour of the gear housing. This makes it possible to pre-assemble a drive device outside the gear unit.
  • a section through a transmission unit 1 is shown.
  • the section takes place in a plane which is spanned by a rotation axis 5 of an input shaft 11 and a rotation axis 6 of an output shaft 3, wherein the rotation axis 5 lies in the longitudinal direction of the ship's hull and is cut by the rotation axis 6 at a right angle and wherein the rotation axis 6 is perpendicular to the axis of rotation 5.
  • the transmission unit 1 is arranged inside the hull.
  • a cylindrical inner contour 7, 8 and 9 are formed at three connection points A, B and C, wherein the position of the inner contours 7 and 9 coaxial with the axis of rotation 5 and the position of the inner contour 8 is coaxial with the axis of rotation 6 ,
  • a drive device 10 is arranged coaxially to the axis of rotation 5 at the connection point A.
  • the drive power of a main drive motor is introduced into the transmission unit 1, which is why the drive device 10 is also referred to as the main drive.
  • the drive device 10 comprises a bearing bush 14 with two tapered roller bearings 41 and 42, a flange 12, an input shaft 11, a cover 15 and a bevel gear 13.
  • the bearing bush 14 has a cylindrical outer contour 18, which results in a fit with the inner contour 7. As a result, the bearing bush 14 is arranged coaxially to the axis of rotation 5 in the transmission housing 4. On an inner contour of the bearing bush 14, the two tapered roller bearings 41 and 42 are arranged. In the tapered roller bearings 41 and 42, the input shaft 11 is rotatable about the axis of rotation 5 stored. At a first end of the input shaft 11, the flange 12 is disposed outside of the transmission housing 4 and rotatably connected to the input shaft 11. About the flange 12, the input shaft 11 is rotatably connected to the drive with a drive shaft of a main drive motor, not shown.
  • the bevel gear 13 is formed at a second end of the input shaft 11 and forms a component together with the input shaft 11.
  • the bevel gear 13 may be formed as a separate component and rotatably connected to the input shaft 11.
  • Between the bearing bush 14 and the flange 12 of the lid 15 is arranged, which is fastened by means of a plurality of screws 46 on the bearing bush 14 concentric with the axis of rotation 5.
  • a radial shaft seal 49 is fixedly disposed on the lid 15, whereby the interior of the transmission unit 1 is sealed against external influences, such as dirt, water, etc.
  • a drive device 20 is arranged in the inner contour 8 of the transmission housing 4.
  • the drive device 20 comprises a hollow shaft 21, a shaft driver 22, a bearing bush 24 with two tapered roller bearings 43 and 44, an adapter flange 26 with a cover 29 and a bevel gear 23.
  • the bushing 24 is analogous to the bearing bush 14 by means of several screws 48 rotatably connected to the transmission housing 4 and has an outer contour 28, which forms a fit with the inner contour 8 and is centered in the transmission housing 4 with respect to the axis of rotation 6.
  • the adaptation flange 26 is also arranged coaxially to the axis of rotation 6 on the bearing bush 24 and rotatably connected by means of a plurality of screws 47 with this.
  • the hollow shaft 21 is rotatably supported in the Kegetrollenlagern 43 and 44 about the axis of rotation 6. At a first end of the hollow shaft 21 is on an inner contour 27th the hollow shaft 21 a shaft drive 22 rotatably connected to the hollow shaft 21.
  • the shaft driver 22 has on its outer contour a toothing 22a.
  • the output shaft 3 is rotatably connected to the inner contour 27 with the hollow shaft 21.
  • a bevel gear 23 is formed so that the hollow shaft 21 and bevel gear 23 form a component.
  • the bevel gear 23 may be formed as a separate component and rotatably connected to the hollow shaft 21.
  • the output shaft 3 can be driven directly by another drive machine in addition to a driving the input shaft 11 driving machine, so that the drive device 20 forms a power take-off.
  • the standing part of the further drive train (not shown) is firmly connected to the adaptation flange 26.
  • a rotating, likewise not shown, driving part of the additional drive train is rotatably connected by means of positive engagement with the toothing 22 a with the shaft driver 22.
  • the output shaft 3 leads vertically down into the in Fig.2 shown control unit and drives there via a further angle drive to the propeller shaft.
  • couplings in the respective drive trains are to be provided, for example, outside the transmission unit 1.
  • the adaptation flange 26 is closed by the cover 29.
  • the wave driver 22 is then no longer needed. If this is rotatable in one embodiment, but arranged axially displaceable in the hollow shaft 21, the shaft driver 22 can be removed in a simple manner.
  • the drive device 20 two functions are combined in the embodiment shown, whereby the effort for the adaptation of an additional drive train is minimal.
  • a bearing for the output shaft 3 is required in a transmission unit according to the prior art.
  • the output shaft 3 is mounted in the drive device 20 by means of the same hollow shaft 21, with which the shaft driver 22 is non-rotatably connected.
  • the drive device 20 is designed so that the adaptation of an additional drive machine is possible in a simple manner. Only the adapter flange 26 and the shaft driver 22 are additionally required to form the drive device 20 as a secondary drive.
  • a drive device 30 therefore comprises neither bearings nor a hollow shaft.
  • a bearing bush 34 with an outer contour 38 is fitted into the inner contour 9 of the transmission housing 4 and connected in a rotationally fixed manner to the transmission housing 4 by means of a plurality of screws 51.
  • the bushing 34 is arranged as well as bearing bush 14 coaxial with the axis of rotation 5.
  • An adaptation flange 36 is rotatably connected by means of a plurality of screws 52 with the fixed bearing bush 24.
  • the adaptation flange 36 is closed by a cover 39.
  • the drive device 30 were designed like the drive device 20 without an additional drive of the gear unit 1 at the connection point C, a bevel gear and thus also hollow shaft and tapered roller bearing would idle with the output shaft 3, which causes, for example, losses in efficiency and wear.
  • parts would be mounted in the transmission unit 1, which are not needed, which is undesirable, for example, for reasons of cost, installation costs and weight.
  • the inner diameter of the inner contours 7, 8 and 9 advantageously chosen such that it is greater than the largest outer diameter of the respective bevel gear 13 or 23. Dienikantriebvorides 10 , 20 can thus be completely pre-assembled in the bearing bush 14, 24 outside the gear unit 1.
  • an output i. the drive of a device outside of the transmission unit 1 take place.
  • Fig.2 shows a perspective view of a marine propulsion of the type described, in which the transmission unit 1 and the corresponding arrangement of the respective power take-offs can be seen. Furthermore, the control unit 2 lying outside of the fuselage is shown in the approach. In the outer view of the drive device 20, the bearing bush 24 and the adapter flange 26, and the lid 29 and the corresponding screws visible. Similarly, in the drive device 30, the bearing bushing 34 and the adapter flange 36, and the lid 39 and the corresponding screws are shown. The drive device 10 with the input shaft 11 is hidden.
