Description

  The present invention relates to a ladder propeller propulsion device and a ladder propeller propulsion method according to the premise of claim 1.

  For example, in particular, a rudder propeller propulsion device, which is specified in the preamble of claim 1 and has a driving prime mover, is known from German utility model DE 200 21 466 U1. It is also well known in practice to use a fluid clutch that is connected to the marine propulsion device, that is, incorporated in the power transmission of the propulsion unit. However, the fluid clutch is also an independent element and has its own filling fluid such as a sealed casing and oil.

  The present invention has and aims to improve known ladder propeller propulsion devices in a particularly inexpensive manner to manufacture and operate.

  The purpose of this is a ladder propeller propulsion device having a drive prime mover, the output shaft of the drive prime mover being operatively connected to the shaft of the propeller via a power transmission device, the propeller shaft being provided outside the hull A propeller shaft housed in a possible rudder propeller housing and provided on the propeller shaft is provided outside the rudder propeller housing and lubricates for the propeller shaft and / or the power transmission device region upstream of the propeller shaft And / or a cooling device, wherein the power transmission device further includes a fluid clutch or a fluid torque converter, and the power transmission device has a functionality common to the fluid clutch or the fluid torque converter and the lubrication and / or cooling device. In a mode where fluid is used, This is achieved by a ladder propeller propulsion device combined with or integrated with the lubrication and / or cooling device.

  Thus, the functional fluid of the lubrication and / or cooling device and the functional fluid of the fluid clutch or fluid torque converter are advantageously realized by supplying the same fluid.

  An advantageous improvement is that the lubrication and / or cooling device comprises the interior of the ladder propeller housing, that the functional fluid is contained within the ladder propeller housing, and / or that the fluid clutch or fluid torque converter is in the ladder propeller housing. More preferably, a fluid contact is made in the interior of the substrate. The latter can be advantageously realized by providing a fluid clutch or a fluid torque converter within the ladder propeller housing or in an extension within the ship hull of the ladder propeller housing. Such an extension is structurally referred to as a conical support tube or support cone.

  Yet another preferred configuration of the present invention provides for the fluid clutch or fluid torque converter to lubricate and / or cool the device in such a manner that the fluid clutch or fluid torque converter ensures delivery of the functional fluid within the lubrication and / or cooling device. Or combining the lubrication and / or cooling device with the lubrication and / or cooling device.

  It can also be advantageously performed that the fluid clutch comprises several fluid clutch units or that the fluid torque converter comprises several fluid converters. Alternatively or additionally, an elastic clutch and / or a shiftable clutch may be provided in the power transmission device.

  Furthermore, the drive prime mover can be advantageously arranged in the hull.

  In the ladder propeller propulsion method according to the present invention, the output shaft of the driving prime mover is operatively connected to the shaft of the propeller via a power transmission device, and the propeller shaft is in a ladder propeller housing arranged outside the hull. And the propeller shaft is disposed on the propeller shaft outside the ladder propeller housing, and the propeller shaft and / or the power transmission device region upstream thereof is lubricated and / or cooled with a functional fluid, and the power The transmission device includes a fluid clutch or a fluid torque converter, which is used to lubricate and / or cool the propeller shaft and / or the power transmission device region upstream of the propeller shaft. Some functional flows of the same functional fluid There is supplied.

  An advantageous improvement is that the lubrication and / or cooling device includes the inside of the ladder propeller housing and that the fluid clutch or fluid torque converter is in fluid connection with the inside of the ladder propeller housing, these improvements. In particular, a functional fluid may be contained within the ladder propeller housing, and more preferably, a fluid clutch or fluid torque converter is provided within the ladder propeller housing, or an extension within the ladder propeller housing, for example, It is arranged in a conical support tube or support cone in the hull.

  Preferably, the fluid clutch or fluid torque converter is combined with the lubrication and / or cooling device in such a manner that the fluid clutch or fluid torque converter ensures the transfer of the functional fluid within the lubrication and / or cooling device or It is further adapted to be integrated into a lubrication and / or cooling device.

  According to a particular configuration, the present invention forms a ship propulsion device of the ladder propeller type, which propulsion device has, for example, an integrated vertically arranged drive prime mover and particularly preferably lubrication and cooling. It has a fluid clutch or fluid torque converter integrated within the ladder propeller housing, which is a component of the device, or within an extension of the housing. Integration of the fluid clutch or the fluid torque converter into the inside of the ladder propeller housing or an extension of the housing enables the construction of a compact propulsion system.

This obviates the need for a fluid clutch or fluid torque converter seal to the surrounding environment that is required for a conventionally arranged fluid clutch or fluid torque converter. The extension described above is referred to as a conical support tube or support cone.

  A fluid clutch or fluid torque converter has a naturally occurring pumping effect from the inside to the outside. This pumping effect is used by the present invention to provide an underwater portion of the ladder propeller propulsion device that is very well cooled by the surrounding water during a voyage, such as seawater, and an upper portion that is cooled little or not at all. In the meantime, a fluid exchange, in particular a lubricating oil exchange, can take place. In currently known designs, a separate pump is required for this purpose.

  The fluid clutch or fluid torque converter may be configured as what is referred to as a double clutch or double converter, which produces twice the transmittable torque for the same clutch or converter diameter. Torque in a given rotational direction is also increased by using a fluid clutch or a fluid clutch turbine wheel having blades angled in the tangential direction in the pump. This preferably takes place in the forward direction with respect to the propeller propulsion. The blade tilt condition results in low transmittable torque in reverse rotation or reverse propulsion, but reverse propulsion is only required in the limited operating situation of the ladder propeller propulsion device.

Further advantages of the present invention are:
-Vibration isolation between the driving machine and the working machine in a compact space;
-Particularly quiet operation is possible by isolating the drive motor from the mechanical structure;
-Reduction of the starting torque of the driving prime mover, i.e. achieving a preferred or particularly low starting torque of the driving prime mover,
-Reduction of types of operating elements by lubrication / cooling of the ladder propeller and filling of the fluid clutch or the fluid torque converter with a single fluid,
-Removal of the pump device by circulating the lubrication / coolant or lubrication / cooling fluid, utilizing the pumping effect of the fluid clutch or the fluid torque converter,
-As little maintenance and inspection as possible by removing seals and removing worn parts of the clutch,
-Protection of ladder propellers against heavy shock caused by ship landing, underwater foreign matter, ice, etc.
