Definitions
- the invention relates to a shaft bracket for a ship drive with a drive shaft mounted in the shaft bracket and at least one propeller.
- the object of the invention is to equip a ship or a boat with counter-rotating propellers with little technical effort and in particular also to convert from a single-propeller drive to a drive with counter-rotating propellers.
- a reversing gearbox is accommodated in the shaft bracket, which is coupled on the input side to the drive shaft and on the output side to a hollow shaft surrounding the drive shaft, both shafts being led out downstream of the shaft bracket, and in that the front propeller is at the end of the hollow shaft and on the end of the drive shaft the rear propeller of a pair of counter-rotating propellers.
- a reversing gear can easily be accommodated in a shaft bracket without affecting its aerodynamic shape. Since the reversing gear is no longer arranged directly behind the drive machine in the ship's hull, but closer to the propeller, the hollow shaft and its bearings can also be made simpler.
- connection elements of the shaft bracket are adapted to the particular shape of the ship.
- the reversing gear can be a mechanical gear.
- An embodiment is characterized by a bevel gear, the input bevel gear is arranged on the drive shaft and the output bevel gear is arranged on the hollow shaft, wherein a reversing bevel gear meshing with the input bevel gear and the output bevel gear is rotatably mounted in the shaft bracket.
- a spacer bush can be arranged on the drive shaft between the input bevel gear and the output bevel gear, which results in a very compact, stable construction.
- the reversing gear can also be a liquid gear and in particular have a pump driven by the drive shaft and a motor driving the hollow shaft.
- the pump and the motor can be in separate chambers of the shaft bracket connected by flow channels be arranged.
- One embodiment is characterized by a gear pump, the driving wheel of which is arranged on the drive shaft, and a gear motor, the driven wheel of which is arranged on the hollow shaft.
- the shaft bracket 1 shown in the drawing has devices at its upper end, in the illustrated embodiments screw connections 2, for connection to a ship's hull, not shown.
- a reversing gear is housed in the shaft bracket 1, which is a bevel gear in the embodiment according to FIG.
- the bevel gear transmission includes an input bevel gear 4 seated on the drive shaft 3, which is connected to an annular spring tensioning set 5 braced with the drive shaft 3.
- the ring spring tensioning set 5 runs in a bearing 6 supported in the shaft block 1 and is sealed on the outside with a seal 7. In front of the seal 7 is a zinc sacrificial anode 8.
- a combing bevel gear 9 meshes with the input bevel gear 4, the shaft journal 10 of which is rotatably mounted in bearings 11, 12 in a blind bore 13 of the shaft bracket 1.
- the reversing bevel gear 9 also meshes with an output bevel gear 14, which is supported by a bearing 15 on the continuous drive shaft 3 and is connected to a hollow shaft 16 surrounding the drive shaft 3 or, as in the exemplary embodiment according to FIG. 1, is integrally formed with the latter.
- the hollow shaft 16 is supported by bearings 17, 18 in the shaft bracket 1 and sealed at the end of the shaft bracket 1 with a seal 19.
- a spacer bush 20 is arranged on the drive shaft 3, on which the two bevel gears are axially supported.
- the hollow shaft 16 has at its free end a seat, not shown, for the front propeller 21 of a pair of counter-rotating propellers, the rear propeller 22 of which is arranged on an associated seat of the drive shaft 3 and is secured in the usual way with a screw fastening 23.
- the drive shaft 3 and the hollow shaft 16 run in opposite directions at the same speed.
- the diameter and the pitch distributions of the two propellers 21, 22 are designed in accordance with the propeller theory.
- the reversing gear is a fluid transmission with a gear pump driven by the drive shaft 3, the driven wheel 24 of which sits on the drive shaft 3 and is connected to the ring spring tensioning set 5.
- the other wheel 25 the gear pump is mounted on both sides via bearings 26 in the shaft bracket 1.
- the gear pump 24, 25 is housed in a separate chamber of the shaft bracket 1, which chamber is connected via flow channels 27, 28 to a further chamber in which a gear motor is housed, the driving wheel 29 of which sits on the hollow shaft 16 surrounding the drive shaft 3 or is connected in one piece with this.
- the other wheel 30 of the gear pump is supported on both sides via bearings 31 in the associated chamber of the shaft bracket 1.
- the drive shaft 3 is supported in a bearing 33 in a partition 32 between the two chambers, which is only penetrated by the flow channels 27, 28.
