Definitions

  • the invention relates to a boat drive for gliding boats, consisting of a drive motor with a leading to the propeller, at an acute angle to the water surface emerging from the transom drive shaft with an internal and an external universal joint, the propeller in a tunnel-like laterally pivotable, after open bottom housing is mounted and the tunnel-like housing at the bottom / rear edge starting from the direction of travel to the propeller bearing gradually extending upwards to about half the diameter of the propeller.
  • a known boat drive of this type is shown in DE-PS 30 42 197.
  • Boat drives designed in this way have already proven themselves in practice, since the given engine power can be used with a high overall efficiency, thereby resulting in high boat acceleration and high top speed can be achieved.
  • the object of the invention is to further improve this boat drive described in DE-PS 30 42 197, in particular to maximize the sliding properties of the boat to be driven, which are determined by the drive.
  • the gliding boat in motion experiences a dynamic buoyancy, which lifts the boat out of the water with increasing speed, so that from a certain speed it only touches the water with the stern or with the step and stern.
  • Decisive for achieving this high speed is the reduction in resistance when the boat is gliding. It must therefore be avoided everything that could impair this resistance reduction or generate avoidable resistance by any drive parts.
  • a further reduction in resistance can be achieved in that the parts of the boat floor still touching the water slide on the water surface at the lowest possible angle.
  • this angle is determined by the location and the Form of the drive.
  • the drive element i.e. the ship's propeller, as in DE-PS 30 42 197, is at approximately the same height as the boat floor, but the drive shaft is at an acute angle to the boat floor given by the design, and that is over the Propeller plane in the direction of travel extending rearward is arranged parallel to the propeller shaft.
  • This optimum is achieved according to the invention in that an upper housing part, which extends from about the propeller bearing against the direction of travel and can be pivoted about an approximately horizontal axis, is sealed against the side housing parts, that between the bottom / rear edge and the At the beginning of the tunnel-like housing an open gap remains in the direction of travel and that another joint (gearbox) is inserted between the cardan shaft and the propeller bearing.
  • the joint is a synchronized shaft joint combined with the propeller bearing, expediently a homokinetic joint or, if only a small angle has to be compensated, a double tooth coupling (curved tooth coupling).
  • the external universal joint is expediently combined with a gear transmission arranged on the housing, in which the drive-side gear lies over the output-side gear which is connected to the propeller via a propeller shaft.
  • the gear transmission can be a spur gear or, at larger angles, a bevel gear.
  • the housing it is again proposed according to the invention to increase the efficiency that it begins with an approximately the contour of the lip following the bottom / rear edge and expands essentially inside and outside following a hyperbolic function (sinh). This results in the lowest flow resistance for the water column to be accelerated by the propeller, combined with a uniform, efficiency-increasing flow to the propeller.
  • sinh hyperbolic function
  • the water flowing in above the housing through the gap which is open in the direction of travel can also be used to cool the gear transmission and to soundproof the exhaust if the space above the housing encloses the external universal joint and the exhaust pipe of the drive motor, including a spray cover is.
  • a water mist then forms in this room with relatively large water droplets, which have an excellent sound-absorbing effect, so that the exhaust noise can hardly be heard outside.
  • the boat still has to be trimmed with regard to its relative position to the water level.
  • this can be achieved roughly by pivoting the tunnel-like housing about a horizontal axis lying on the outside universal joint until the ideal line of action to the boat bottom is established.
  • a fine trim results from the fact that the upper housing part, which extends from about the propeller bearing against the direction of travel, is pivoted about an approximately horizontal axis, this housing part being sealed against the lateral housing parts. This accelerates the accelerated water jet more or less strongly against this housing part or against this trim tab, and will thus adjust the relative position of the hull to the water level.
  • a bearing body (2) is attached to the transom (1) of a gliding boat, in which a gimbal (3) is arranged so as to be pivotable via vertical axle bolts lying parallel to the transom (1). Inside this gimbal (3), a tunnel-like housing (4) is attached to horizontal axle bolts arranged outside the center, which, starting with a knife-like lip (15), extends beyond a propeller (6) and follows a hyperbolic function.
  • the outer universal joint (7) of a drive cardan shaft (8) is also accommodated in the bearing body (2).
  • An intermediate shaft (9) leads from the universal joint (7) to the propeller (6) via a synchronous shaft joint (10).
  • the entire tunnel-like housing (5) can be pivoted about its horizontally lying articulation axis by a hydraulic cylinder (11). This pivoting serves for rough trimming of the boat as well as for lifting the entire housing during road transport or when changing propellers. Fine trimming is carried out by an upper housing part (12) which is attached to the end of the housing and lies horizontally around one axis (13), for example via a further hydraulic cylinder (not shown), is pivotable.
  • the drawing also shows a spray cover (14) which covers the space above the housing (5) starting from the housing lip (15) until the articulation of the hydraulic cylinder (11).
  • the external universal joint (7) is located in this room.
  • the exhaust (16) of the drive motor also opens into this space.
  • the propeller plane of the propeller (6) is not at an angle to the water level, but exactly in the normal plane, which results in a good efficiency of the propeller ( 6) results. This is achieved by the constant velocity shaft joint (10), which is attached inside the housing (5).
  • the propeller (6) sucks water into the space of the tunnel-like housing (5) and expels this water column to the rear (arrow 17).
  • the fact that the lip (15) of the housing (5) is located somewhat below the bottom (18) of the sliding boat means that water also flows into the gap (19) open in the direction of travel, which not only effectively prevents Air can be sucked in, but it also cools the shaft bearing (7) running in oil.
  • This inflowing water splashes against the spray cover (14), so that the entire space above the housing (5) fills with a coarse droplet of water mist, which has a very good sound-absorbing effect, so that the exhaust noises from the exhaust (16) can hardly be heard to the outside are.
  • a gear (20) is arranged after the outer universal joint (7), from which the propeller shaft (21) leads to the propeller (6).
  • the gear (20) lowers the propeller shaft and thus also the propeller so that its line of action lies approximately at the bottom (18) of the sliding boat.
  • the gear (20) is a spur gear, so that the propeller plane of the propeller (6) is not exactly in the vertical plane or in the normal plane to the water level. A slight angular misalignment is achieved by the universal joint (7). If the propeller plane (6) is to be placed exactly in this normal plane to the water level, a bevel gear is expediently used instead of the spur gear.
