Definitions
- the invention relates to a water jet drive for watercraft.
- Water jet propulsion systems are commonly used today, especially for fast watercraft in various categories and applications.
- EP 0 657 348 A shows the principle of a conventional water jet drive in FIG.
- a pump wheel or impeller is mounted in a housing and driven via a coaxial shaft.
- Twist losses in the impeller are generally preceded by a distributor in the inlet.
- Shaft and diffuser are resistive interference attachments.
- Gap losses occur between the impeller and the housing wall and there is a risk of gap cavitation. Foreign bodies can wedge between the impeller and the housing wall, which can lead to blockages and damage.
- the invention has for its object a water jet drive for a
- Reduction and reversing gear is a common compact unit. This unit can be installed and removed when the ship is floating.
- Fig. 1 shows in a longitudinal section a jet drive with two impellers.
- Fig. 3 shows a section through the object of Fig. 1 in the section plane C-D.
- the water jet drive shown is intended for all types of watercraft, in which this propulsion system generally has advantages over other propulsion systems. It comprises a housing (1) which is preceded by an inlet channel (2) and an outlet nozzle (3). The housing accommodates two pump impellers (4.1) and (4.2) arranged coaxially one behind the other. Every impeller is one
- the ring gear (4.1.1) or (4.2.1) is enclosed and non-rotatable with it connected.
- the external mechanical drive (5) is also arranged in the housing 1. This comprises a common drive shaft (5.1) on which two drive gears are connected in a torsionally rigid manner.
- Gear (5.2) meshes with an intermediate gear (5.3), which in turn meshes with the ring gear (4.1.1) of the first impeller (4.1).
- Gear wheel (5.4) on the other hand, meshes with ring gear (4.2.1) of the second impeller (4.2). This results in a different direction of rotation for the two impellers and, in addition, impeller (4.2) maintains a higher speed than
- Impeller (4.1) to take into account the flow velocity induced by the impeller (4.1).
- Housing (1) is connected to parts (2) and (3) via flange connections and can therefore be mounted as a compact unit from the outside.
