    The present invention relates to a device for supporting a marine propeller shaft with a bearing housing which engages around the propeller propeller shaft and by means of at least one support strut protruding from a ship's hull part is supported, wherein in the bearing housing at least one the ship propeller shaft is rotatably mounted bearing shaft bearing.
    In the case of ship drives, which comprise a drive shaft which extends outwards from the ship's hull to the bottom / obliquely downwards, is mounted on the end value of a propeller or a propeller, the propeller shaft between ship propeller and propulsion engine respectively between ship propellers and hull exit is at least a supporting strut supported on the ship's hull, wherein through said supporting strut in particular transverse forces and bending moments can be absorbed on the drive shaft, which may, for example, originate from the ship's propeller. Optionally, axial forces can also be absorbed in order not to make the support length or buckle rod length for the shear-force reaction forces too long. Such supporting struts are usually of a vina-shaped design and have at the end of the ship's hull projecting a bearing housing which, in the manner of a bearing eye, grips the ship's propeller shaft and receives an axle bearing which is rotatably mounted on the drive shaft and, for example, as a liquid-cooled slide bearing or also on another one. carried out in a manner that is The end on the ship's hull side of the support strut is attached to the ship hull respectively a constructional part connected thereto to enable or support the said supporting forces. If the bearing housing is supported by a separate support strut, a corresponding supporting device is sometimes referred to as a P-brackets due to its shape, while supporting devices with two V-shaped supporting struts extending from the bearing housing to the ship's hull are sometimes referred to as a Y-bracket.
    With such support devices, the axle bearings accommodated in the bearing housing must be regularly exchanged or at least maintained, for example turned out or treated in another way, for which the axle bearing normally has to be removed from the drive shaft. For this purpose, the propeller's propeller must normally be mounted away from the drive shaft and the shaft bearing must be pushed out of the bearing housing, but both are difficult and time-consuming and sometimes also with special tools such as subtraction devices, since the propeller propellers and their fasteners are affected by environmental influences such as corrosion by salt water. , occupation with mussel and micro-organisms etc. are stuck. The same also applies to the shaft bearing, which should be pulled out over the propeller shaft, but can often only be released by cutting open. In any case, for this maintenance work, the ship in question must normally be brought immediately to shore or transferred to a dry dock, which causes high costs.
    Supporting devices for marine propeller shafts of the above-mentioned type are known, for example, from documents US 5,248,270, US 4,338,829 or US 3,286,681.
    Starting from this, it is an object of the present invention to provide an improved device for supporting propeller propeller shafts, avoiding disadvantages of the prior art and further developing the latter in an advantageous manner. In particular, simple maintenance and changing of the shaft bearing should also be made possible with a propeller screw fixed as such.
    According to the invention, the said object is achieved by a device according to claim 1. Preferred embodiments of the invention are subject of the subclaims.
    It is therefore proposed to divide the bearing housing of the support so that a bearing housing part of the ship's propeller shaft can be removed transversely of its longitudinal direction so that access to the shaft bearing exists axially from the bearing housing even without the shaft bearing to beat out. According to the invention, the bearing housing has a multi-part structure with at least two sub-shells which can be releasably mounted to each other in such a way that at least one part of the shell can be removed transversely of the longitudinal axis of the bearing housing from the ship propeller drive shaft. In particular, the at least one detachment part shell can form a sufficiently large circumferential sector of the bearing housing, so that after the at least one part shell the axle bearing and / or the ship propeller shaft can be taken transversely relative to the longitudinal axis of the bearing housing.
    For example, the bearing housing may consist of two substantially equal half-shell sizes, which completely enclose the marine propeller shaft when assembled. By removing one of the half shells, a circumferential sector of about 180 ° is released from the ship propeller shaft so that it can be moved outwardly from the other half shell to the longitudinal axis of the drive shaft. In a more alternative development of the invention, however, more than two half-shells, for example three sub-shells, which always extend over approximately 2/3 π, can also be present, of which two or more sub-shells are detachably designed, so that a larger circumferential sector is free of the drive shaft. and the access is once again simplified. On the other hand, a two-part embodiment comprising the above-mentioned two half-shells with regard to shape resistance and bearing stiffness as well as simple manufacture is advantageous, because here the bearing housing only has to be assembled from two parts.
    In order to make it possible to change the axle bearing even without dismantling the propellers without sawing off the axle bearing, it is provided in a more advantageous development of the invention that the axle bearing also has a multi-part structure and comprises several partial bearing shells, which always extend over a peripheral sector and complement each other such that they jointly support the bearing drive shaft radius. The bearing shells can thereby complement each other up to approximately 360 °. Depending on the bearing version, however, longitudinal gaps between bearing shells can also remain, so that the drive shaft is supported circumferentially over, for example, three times 100 °.
    The bearing housing which accommodates the shaft bearing can in principle comprise partial shells which can be completely detached from one another, for example in such a way that a half shell on both sides or opposite longitudinal sides can be detached entirely from the other half shell. In an advantageous further development of the invention, however, the sub-shells can also be hingedly connected to each other, wherein in an advantageous manner a corresponding sleeve hinge can be designed in the manner of a hinge that a substantially parallel to the longitudinal axis of the includes a sleeve-extending hinge pin which makes it possible to pivot a corresponding sleeve-part shell in a plane perpendicular to the longitudinal axis of the drive shaft or transversely of the longitudinal axis of the drive shaft.
    Such a hinged connection of the bearing shell sub-shells has the advantage that the removable shell can also not be lost when mounted under water. In particular, however, the closed or assembled position of the part shells of the bearing housing, in which the bearing housing must be aligned with the longitudinal axis of the drive shaft act, can be found more easily with such a hinged connection.
    In a further development of the invention, one of the bearing shell sub-shells can be rigidly and inseparably connected to the at least one support strut which supports the bearing housing on the ship's hull. It would, of course, also be possible to detach all of the sub-shells from the support strut. By a fixed connection of one of the sub-shells to the support strut, the exact adjustment position of the completed bearing housing can be found more easily.
    The part shells of the bearing housing can in principle be connected to each other in different ways or be held together in the position that is attached to each other, whereby form-fitting clamping and / or clamping means can advantageously be present, in particular in the shape of screw bolts. The sub-shells can have outwardly projecting connecting flanges on the edge parts thereof, which form the connecting place between two sub-shells, which can be clamped onto each other by means of said screw bolts or other clamping means.
    The part shells of the bearing housing can contain parts on the inner peripheral side bearing holder for the axle bearing to be received or the bearing shells thereof, in order to be able to precisely position the axial bearing or the bearing shell thereof and to fix it axially. Moreover, the mounting of a new axle bearing is considerably simplified by such bearing-scale mounting parts.
    The invention is explained in more detail below with reference to a preferred exemplary embodiment and accompanying drawings. In the drawings: figure 1 shows a diagrammatic perspective view of a device for supporting a ship propeller shaft according to an advantageous embodiment of the invention, wherein the bearing housing of the device in an open position is shown obliquely from below, in which a half-shell is shown Figure 2 shows several side views of the device of Figure 1 in visible directions transversely of the bearing, the partial view a) a top view from the top side, the partial view b) a side view approximately in a horizontal view direction and the partial view c) a top view from below, figure 3 shows a schematic view of the opened bearing housing from the previous figures in a view direction parallel to the longitudinal axis of the bearing housing and propeller propeller shaft, figure 4 shows a perspective view of a half-shell from the lower house from devoorga other figures and figure 5 show a perspective view of a half-shell of the shaft bearing, which can be used in the bearing housing of the preceding figures and which rotatably supports the drive sleeve.
    As Fig. 1 shows, the propeller propeller shaft 1, which can be attached to the end of a propeller or propeller propeller 2, can be supported by means of a bearing housing 3 which grips around the propeller propeller shaft 1 through a fin-like support strut 4 on a only designated hull part 5 is supported. In the drawings, a support in the form of a so-called P-bracket is shown, wherein said support sleeve 3 is supported on the ship's hull only by means of a support brace 4. Alternatively, however, multiple supporting struts 4 could extend away from the bearing housing 3 towards the ship's hull, for example in a V-shaped manner of fitting in the form of a so-called V-bracket.
    The bearing housing 3 in this case consists of a plurality of part shells 6, 7, in particular in the form of two half shells, which are always curved in the form of a part-cylinder shell and always enclose a peripheral segment of the drive shaft 1. The shell shells 6 and 7 complement each other so that they are completely, ring-locked, around the drive shaft 1.
    A first sub-shell 6 can thereby be rigidly attached to the support strut 4, for example welded or screwed or cast or fixedly mounted in another manner. For example, the support strut 4 may be in a longitudinal groove in the sub-shell 6 and fixed there by screws or the like.
    The other sub-shell 7 is hinged to the above-mentioned sub-shell 6 by a sleeve hinge 8, so that the two sub-shells 6 and 7 can be pivoted relative to each other. The sub-joint 8 can herein form a hinge, which comprises a joint shaft 9, which extends approximately parallel to the longitudinal axis of the sleeve or the longitudinal axis of the drive shaft, compare figures 1 and 3. For example, said sleeve joint 3 can be arranged in the manner of a piano hinge are performed.
    The sleeve pivot 3 makes it possible to pivot the sub-shell 7 transversely of the longitudinal axis of the bearing housing 3 or of the longitudinal axis of the drive shaft, so that a peripheral half of the drive shaft 1 becomes free, compare FIG. 3.
    An axle bearing 10 accommodated in the bearing housing 3 is also designed in several parts and can in particular be composed of two half bearing shells 11 and 12, which complement each other to an overall cylindrical axle bearing. Said shaft bearing 10 can be a sliding bearing, which is cooled by water and which drives the drive shaft 1 so that it can rotate. The half bearing shells 11 and 12 may be formed for this purpose from a suitable material.
    In order to be able to close the bearing housing 3 or to hold the sub-trays 6 and 7 in the pivoted position, the trays 6 and 7 can always comprise a mounting flange 13 at their ends remote from the sleeve joint 8 and at the sides remote therefrom, respectively. the connecting place between the two sub-scales 6 and 7 to the outside. By means of suitable clamping and / or tensioning means, the aforementioned mounting flanges 13 can be tensioned to one another in order to close the bearing housing 3 firmly. The aforementioned mounting flanges 13 may comprise bolt recesses for this purpose to be drawn against each other by means of screw bolts.
