Definitions
- the invention relates to a variable pitch propeller for motor and sports boats a hub, arranged thereon sealed in circumferential recesses Adjustment plates, which are adjusted by means of an adjustment device around radial axes are adjustable, and with wings with a in the associated recess engaging wing base detachable on the assigned adjuster plate are fastened, each adjusting plate having a screwable screw into the recess the retaining ring encircling the adjustment plate without play, but is rotatably held at the bottom of its recess.
- Such an adjustable propeller is known (EP 0 589 338).
- the one in operation Wing forces that occur are caused by the adjustment plate and the retaining ring transferred the hub construction.
- the adjustment device includes in the Hub axially displaceable adjusting plunger, each with a pin off-center engage on an adjustment plate and, in the event of axial displacement, the adjustment plate twist.
- the adjustment plungers are on both sides of the adjustment plate sealed so that no water from inside the hub to the adjustment plate can reach.
- the wings are screw-fastened over their wing feet attached to their adjuster plates.
- the wing feet are less Tolerance inserted in the assigned recesses and have seals on the one hand against the wall of the recess and on the other hand seal against the retaining ring, so that none from the outside Water can get to the adjustment plate.
- variable pitch propeller Sports boat If in a motor or equipped with such a variable pitch propeller Sports boat the blades of the variable pitch propeller are replaced should or must, e.g. after a wing deformation after a Ground contact, the wings with their wing feet can be removed from the adjuster plates must be solved when installing a new wing care must be taken to ensure that the seal between the wing base and Recess or retaining ring is inserted correctly.
- the object of the invention is to simplify the replacement of the propeller blades.
- the diameter of the wing base is smaller than the diameter of the recess and that the retaining ring on the one hand against the wall of the recess and on the other hand against the Adjustment plate is sealed. Then the sealing of the adjustment plate and the parts of the adjusting device acting on it independently of the wing or wing base. To replace a wing you only need the Screw fastening between wing base and adjustment plate to be loosened. When removing a wing and inserting a new wing needs no longer tolerances between the wing base and the recess to be respected. Because of the permanent sealing of the adjustment plate and the parts of the adjusting device acting on it can be the wings can also be replaced under water and even by laypersons.
- the recess is as Stepped bore is formed and the retaining ring has a to the Stage extending radial flange, between the and the stage one Seal is arranged.
- the Radial flange over a circumferential recess of the adjustment plate extend and a between the radial flange and the circumferential recess Seal be arranged.
- the retaining ring can have an axial flange surrounding the adjustment plate have, which in the assembled state to the bottom of the recess extends.
- the variable pitch propeller shown in the drawing includes a hub 1 and three wings 2 arranged thereon, of which only one in the drawing is reproduced.
- the hub 1 has a central hub body 3 with a receptacle 4 for a drive shaft, not shown.
- the hub body 3 is surrounded by a support ring 5 for one on it attached hub shell 6.
- Housing 7 arranged, which are supported on the hub body 3.
- the housings 7 have through-holes 8 parallel to the axis, in which adjustment plunger 9 are guided.
- the adjustment plunger 9 are opposite Housing 7 sealed, on the left side of the figure with a Sealing ring 10 and on the right side of the figure with a bellows 11, which extends with its closed end into the bore 8 and its open end with a radial flange 12 between the Housing 7 and a cover 13 which closes the bore 8 is.
- Each housing 7 has a recess designed as a stepped bore 14 on.
- the inner section with the smaller diameter of the recess 14 carries an internal thread 15 for one with an associated external thread provided retaining ring 16, 17.
- a radial flange 16 of the retaining ring extends to the step of the stepped bore. Between the level and the radial flange 16 is a seal 18 is arranged, the radial flange 16 seals against the recess 14.
- An inwardly directed portion of the radial flange 16 extends via a circumferential recess 19 of an adjustment plate 20, which is from the retaining ring 16, 17 is held on the bottom 21 of the recess 14 with tolerances.
- Through the bottom 21 extends into an associated eccentric Recess on the adjusting plate 20 engaging pin 22 of the adjusting plunger 9, so that the adjustment plate by axial movement of the adjusting plunger 9 20 can be rotated about a radial axis 23.
- the circumferential recess 19 of the adjustment plate 20 has a circumferential groove 25 for one therein Seal to be used, so that the retaining ring 16, 17 also opposite the adjustment plate 20 is sealed.
- the axial flange 17 of the retaining ring comprises the adjusting plate 20 and extends to the bottom 21 of the recess 14.
- the fits between the retaining ring 16, 17 and the adjustment plate 20 are selected that forces and moments occurring during operation from the adjustment plate 20 via the retaining ring 16, 17 on the housing 7 and thus the hub 1 be transmitted.
- a wing base 26 On the top of the adjustment plate 20 is a wing base 26 with one wing 2 adjoining it in one piece with at least one screw 28 releasably attached. At least one dowel 29 allows together with the Screw 28 an exact positioning of the wing 2 on the adjustment plate 20th
- the wing base 26 has a smaller diameter than the recess 14.
