Definitions
- the invention relates to a ship propulsion system with a drive machine and a rudder double propeller which is driven by the drive machine via drive shafts, angular gears and transmission output shafts, the propellers being connected in a rotationally fixed manner to the output shafts.
- a ship propulsion of this type is known from DE 870 655.
- the power of the inboard engine is introduced into a vertically arranged drive shaft, the lower end of which is led through the ship's floor to the outboard, drives horizontally arranged output shafts there via angular gears, each end of which is turned away from the respective angular gearbox, which is used to propel the ship serving propeller.
- Such a system can be designed as a rudder propeller in that not only is the drive power introduced at the upper end of the vertically arranged shaft, but an actuating motor can be brought into effect in such a way that a cladding tube concentrically surrounding the drive shaft the longitudinal axis of the drive shaft can be pivoted up to 360 ° or all around. If the servomotor is activated, the propellers will eventually turn
- ERSA ⁇ ZBLA ⁇ T (RULE 26) the longitudinal axis of the drive shaft is pivoted, and not only is the power of the prime mover converted into thrust power, but the possibility is also provided of using the power for the maneuvering of the ship by swiveling the underwater part of the propulsion system through 360 °.
- each propeller is assigned an angular gear and an output shaft. The two propellers can thus be driven independently of one another.
- the technical complexity of this drive is not in relation to the benefit that can be achieved from the separate functioning of the two propellers.
- the invention is based on the object of developing a ski drive of the type mentioned at the outset, which is simple in terms of production technology with a high degree of efficiency.
- a guide device is known from DE 293 611, but it is a propeller arrangement with a horizontal drive shaft, i.e. a propeller system without rudder function.
- the angular gear and the output shaft are usually surrounded by a housing that serves to support the output shaft and the angular gear.
- this housing forms a fixed unit with the guide device, while the housing tube surrounding the drive shaft is preferably designed as a guide vane. This means that the intermediate area between the two propellers is optimally used in terms of flow technology for an effective control device.
- the guide device can be formed from two guide vanes which are arranged at 180 ° around the axis of rotation of the propellers and which extend radially from the axis of rotation of the propellers. It is of course also possible to provide more than two guide vanes which are arranged in a rotationally symmetrical arrangement about the axis of rotation of the propellers.
- the guide vanes preferably have curved airfoil profiles, it being fluidically very advantageous if the curvature consists of a pre-swirl and a post-swirl curvature. The re-spin of the front propeller can thus be directed effectively and the energy lost during the re-spin of the front propeller can be recovered by the propulsive force generated during the flow around the guide vane.
- the longitudinal extension of the guide vanes is largely equated to the radius of the tip circle of the propellers.
- FIG. 3 shows a section along the line III-III in Fig.l
- FIG. 5 shows another example of the control device.
- 1 shows a ship drive designed as a rudder double ropel with a drive machine arranged in the ship's hull with a vertical drive shaft 1 and drive propellers outside the ship's hull.
- a drive machine comprising a motor and gear acts on the upper end of the vertical drive shaft 1 in order to set the drive shaft 1 in rotation about its longitudinal axis 2 at a variable speed.
- the lower end of the drive shaft 1 has the input cone ad 3 of an angular drive 3, 4 rotatably associated, which is in operative connection with the output bevel gear 4 of the angular drive 3, 4.
- the output bevel gear 4 rotatably supports a horizontal output shaft 5 which extends in both directions and at the free ends of which a propeller 6, 7 is arranged in a rotationally fixed manner.
- the propellers will generally be structurally different, although tip circles 14 with the same diameter and similar wing geometries may be possible. Due to the common assignment to the output shaft 5, they have the same direction of rotation and the same speed and, for example, flow in the same direction according to arrow A.
- the angular gear 3, 4 is surrounded by a housing 9 in which the output shaft 5 is rotatably mounted by means of two bearings 10, 11.
- This housing 9 is carried by a housing tube 9a concentrically surrounding the vertical drive axis 1 and pivotable about its longitudinal axis for the rudder function.
- the underwater part of the drive system can be arranged within a nozzle 12.
- the front propeller 6 generates a residual or post-swirl in its outflow, which represents lost energy.
- the downstream, co-rotating propeller 7 is acted upon by the outflow of the front propeller. Without a guide device between the two propellers 6, 7, the above-mentioned unfavorable outflow would lead to increased cavitation and increased energy losses.
- a guide device 8 is provided between the two propellers 6, 7, with which the re-spin of the front propeller 6 is directed.
- lost energy is recovered by generating a propulsive force in the flow around the device.
- a pre-twist is generated for the downstream propeller 7 so that it can implement a higher energy gradient.
- the second propeller 7 will preferably have a structural design that differs from the first propeller 6.
- the guide device 8 consists of two guide vanes 8a and 8b, one guide vane 8a being formed by the housing tube 9a surrounding the vertical drive shaft 1.
- the second guide vane 8b is located on the lower side 9b of the housing 9 surrounding the horizontal output shaft 5, i.e. offset by 180 ° from the first guide vane.
- Both guide blades 6, 7 form a structural unit with the overall housing 9, 9a.
- FIGS 2 and 3 each show a cross section of the upper guide blade 8a and the lower guide blade 8b. Thereafter, the guide vanes 8a, 8b have curved ones
- Wing profiles which have a pre-swirl curvature ⁇ for deflecting the flow for the second propeller 7, and a post-swirl curvature ⁇ for straightening the re-swirl of the first propeller 6.
- the longitudinal extent L of the guide blades 8a, 8b corresponds, as shown in FIG. 4, to the radius R of the tip circle 14 of the propellers 6, 7.
- FIG. 5 shows another example of a guide device in the same section as in FIG.
- three instead of two guide blades 15, 16, 17 are provided in a rotationally symmetrical arrangement about the common axis of rotation 18 of both propellers 6, 7.
- the guide device can of course also consist of more than three guide vanes.
