Definitions
- the invention relates to a jet drive, in particular for watercraft with a rotor, on the inside of which blades are arranged and a housing in which the rotor is rotatably mounted.
- Such a jet drive is known, for example, from DE 39 12 910 C2, in which case the rotor is designed in the form of a tube with an internal screw.
- the motor can be driven mechanically or in the form of an electric ring motor in which the rotor thus forms part of the electric motor.
- the invention is therefore based on the object of proposing a bearing for the jet drive described above, which ensures a long service life.
- the storage should also enable the realization of large rotor diameters for powerful jet drives.
- This object is achieved in that the bearing between the rotor and the housing has seawater-resistant carbide.
- seawater-resistant carbide means that the bearing no longer has to be sealed, so that the bearing damage is eliminated from the outset if the leakage occurs.
- Silicon carbide or aluminum carbide is preferably used, since these two materials, in particular silicon carbide, have high seawater resistance and, on the other hand, the necessary strength.
- the bearing between the rotor and the housing exclusively from carbide, since the materials used for the bearing are either not corrosion-resistant or have a lower resistance to sea water, which would lead to premature wear of the bearing.
- the bearing is advantageously designed as a plain bearing.
- the bearing in the rotor and / or the bearing in the housing is formed from a plurality of bearing segments.
- the bearing is formed by a plurality of bearing segments, it is advantageous to form the bearing segments at least on the rotor, so that the centrifugal force causes this Water between the bearing segments is pressed outwards, resulting in a pumping effect.
- the housing encloses the rotor in such a way that there is a cavity between the outside of the rotor and the inside of the housing.
- the bearing segments are advantageously fixed to the rotor or housing by positive locking, for example with the aid of a trapezoidal geometry and possibly subsequent gluing.
- FIG. 1 shows a side view of the jet drive according to the invention
- FIG. 2 essentially section AA from FIG. 1, the holder and blades not being shown,
- FIG. 3 shows the lower part from FIG. 2 in an enlarged representation
- FIG. 4 shows an enlarged perspective partial view of the bearing in the housing
- Figure 5a and 5b forehead and side view of a bearing segment for the rotor
- Figure 6 shows a pitch circle of the side-by-side bearing segments on the rotor.
- FIG. 1 shows a side view of a jet drive for watercraft, which is based on the drive concept
- Electric ring motor is based.
- part of a boat hull 19 is also shown with an opening 20 through which the jet drive can be extended and retracted.
- a shaft 21 is formed in the boat hull 19, in which the jet drive is received in the retracted state.
- the jet drive has a rotor 1, on the inside of which are arranged inwardly directed blades 2.
- the blades 2 are clamped on the rotor 1 and can also be replaced individually.
- the rotor 1 is accommodated in a housing 3, which in turn is connected to a holder 4.
- the holder 4 has a flange 5 towards the housing 3 and is connected to the housing 3 via the flange 5.
- the holder 4 is designed as a hydraulic cylinder, which is fixed at its upper end via a screw 6 on a cover 7 of the shaft 21.
- a generator (not shown) or another power source, usually a diesel generator, which supplies the jet drive with the necessary current via a line 8.
- the hydraulic cylinder 4 is accommodated in a sleeve 22 with a groove 23 into which a bolt 24 engages, which in turn is firmly connected to the cover 7.
- the bolt 24 and the groove 23 form a link guide, so that the jet drive is extended in the straight part of the groove and the jet drive is rotated in the spiral-shaped part of the groove.
- a sealing plate 27 with a sealing bead 28 is arranged in order to keep the water from the upper part of the shaft.
- the opening 20 can be closed by a lamella roller 29 which is driven by a drive 30 e.g. can also be closed in the form of a hydraulic or pneumatic cylinder.
- the jet drive is shown in dashed lines in the extended state. Depending on the design of the jet drive, it can be used as the main drive and only as an additional maneuvering aid, since it can be swiveled through 360 ° without any problems and can also be easily extended and retracted due to its low weight.
- FIG. 2 essentially shows the section AA from FIG. 1, only the interior of the rotor 1 and the housing 3 being shown and the blades 2 not being shown.
- Figure 3 shows the lower part of Figure 2 in an enlarged view.
- the rotor 1 essentially consists of the two rotor parts 1 a and 1 b, which are screwed together and, between them, receive an electric motor rotor ring 9 centrally on its outside.
- the holding flanges 10a and 10b are provided on the sides of the rotor for fixing the blade segments.
- the rotor 1 is surrounded by the housing 3 in a shell-like manner, the housing 3 likewise being formed from two housing elements 3a and 3b, which together as well as the two
- Rotor parts la and lb are screwed and clamp 11 between them for the electric motor.
- the rotor 1 is mounted relative to the housing 3 via two slide bearings 12a and 12b so that there is between the electric motor
- Rotor ring 9 and stator ring 11 results in a minimal air gap 13.
- the bearings 12a and 12b are designed as carbide bearings in the form of silicon or aluminum carbide.
- carbide is resistant to sea water and, on the other hand, it has very good sliding properties in connection with water.
- a plain bearing 12a or 12b consists of one on its free
- the rotor bearing 14 and also the housing bearing 15 can be manufactured in one piece. With large diameters, it is almost only possible to realize a multi-part rotor bearing 14 and housing bearing 15.
- Figure 4 shows a schematic perspective view of the multi-part design of the housing bearing 15.
- Housing 3 set They can also be glued.
- the bearing segments 15 can be spaced apart by a certain distance d as shown in FIG. 4 or grooves 15 can be formed on the bearing segments.
- Figure 5a shows in cross section the rotor bearing 15, which has a trapezoidal recess 16 on its inside, so that the bearing can be attached to the rotor 1 on a trapezoidal bead.
- the bearing segments of the rotor bearing 14 are also advantageously glued in the trapezoidal recess 16 and then ground.
- Figure 5b also shows the side view of a bearing segment 14 wherein it can be seen that the sides of the bearing element 14 are each radially rounded.
- FIG. 6 A partial circle of the bearing elements 14 is shown in FIG. 6, wherein it can be seen that the roundings on the side of the bearing elements 14 result in narrowing and then widening gaps S.
- the liquid which is located in the gaps S, is pressed outwards by the centrifugal force during rotation and thus reaches the cavity 17 (see FIG. 3), which is formed between the rotor 1 and the housing 3.
- the housing bearing segments are also spaced apart, the water pumped into the cavity 17 can flow out again between the housing position segments 15. It is also possible to provide a bore 18 on the housing 3 through which the water pumped in via the rotor bearing 14 can exit again.
- an external pump can alternatively be connected to the bore 18, which pumps filtered water into the cavity 17 and thus generates a certain excess pressure and rinses the bearings with filtered water.
- the bearings exclusively from carbide, in particular silicon carbide, it is possible to provide the storage unsealed as a water bearing, thereby avoiding complex sealing and at the same time achieving excellent cooling by the water.
- the carbide bearing can also be used as an air bearing for an air drive.
- both the rotor and the housing including the bearing can be pre-assembled and ground.
- the housing only has to be loosened again for assembly and screwed in again after inserting the rotor.
