Definitions

  • the present invention relates to a variable pitch boat propeller, of the type in which each blade is constrained, directly or indirectly, to the motor shaft of the boat in such a manner as to be able to rotate about an axis transverse with respect to the axis of the motor shaft, by means of an external cylindrical body.
  • the external cylindrical body of the propeller is fitted coaxially onto an internal cylindrical body, which in turn rotates integrally with the motor shaft of the boat.
  • Coupling of the external cylindrical body with the internal cylindrical body is generally produced using bolts, screws or other threaded securing means, with axis both transverse and parallel to the axis of the motor shaft, or of the propeller.
  • the external cylindrical body is usually constituted by several complementary parts, which are mutually secured using bolts, or screws, or other threaded securing means, also having axis transverse and/or parallel to the axis of the propeller.
  • the propeller is usually installed on the motor shaft by means of a lock nut which, at the rear (stem) of the propeller, is screwed onto a corresponding threaded end portion of the motor shaft and is shaped in such a manner as to keep the motor shaft and the internal body of the propeller coupled, preventing the mutual release thereof.
  • This propeller which has a lock nut positioned inside the internal cylindrical body, besides being somewhat difficult to install and remove, due to the specific arrangement of this lock nut, also has the drawbacks set forth above in relation to the presence of threaded means to secure the various parts constituting the external cylindrical body of the propeller.
  • These retaining means can, for example, be constituted by a front stop integral with the internal cylindrical body, and by one or more elastic sealing rings, with a relative "Seeger” ring, positioned at the rear of the propeller, and can act as constraining elements of the external cylindrical body to the corresponding internal cylindrical body.
  • a propeller of this type is described in the Italian patent application ITM12008A001667, by the same Applicant, wherein the use of these mechanical retaining means for interlocking of complementary parts, between the external and internal cylindrical body of the propeller, makes it possible to avoid the use of bolts, screws or other threaded securing means of the various parts forming the external cylindrical body.
  • variable pitch boat propeller according to the preamble of the annexed claim 1 is disclosed in EP 2 239 192 A1 .
  • the object of the present invention is to produce a variable pitch boat propeller which overcomes the drawbacks of prior art indicated above.
  • a further object of the present invention is to provide a variable pitch boat propeller which is highly reliable and at the same time easy to install and remove without the use of screws, pins, bolts and similar constraining elements between the various propeller components.
  • a further object of the present invention is to produce a variable pitch boat propeller which has a simple structure, which eliminates or minimizes the possibility of its components, including the nut that locks the propeller on the motor shaft, becoming disassembled during the step to remove/install it from/on the motor shaft.
  • variable pitch boat propeller according to the first independent claim and the subsequent dependent claims.
  • the variable pitch boat propeller according to the present invention comprises at least one internal cylindrical body and at least one blade pivoted to an external cylindrical body of the propeller constituted by one or more juxtaposed parts, and coaxial to the internal cylindrical body which is in turn fitted coaxially on a motor shaft and constrained thereto by means of a lock nut.
  • the propeller also comprises retaining means, which cooperate with the internal cylindrical body of the propeller, to maintain in assembled position, with interlocking of complementary parts, at least the internal cylindrical body, the external cylindrical body and the blades.
  • the propeller comprises means to constrain by coupling the lock nut - which as stated constrains the propeller to the motor shaft - to the external cylindrical body of the propeller, or at least a part thereof.
  • the presence of retaining means, which cooperate with the internal cylindrical body, allow the components of the propeller to be kept in assembled position, with interlocking, so that it is particularly simple to install on/remove from the motor shaft.
  • the constraining means with which it is provided also keep the nut inside the propeller, coupled with the external cylindrical body of the propeller. In this manner, the nut used to constrain the propeller to the motor shaft also remains in assembled position inside the propeller following operations to remove it from the motor shaft.
  • the internal cylindrical body of the propeller comprises at least one abutting portion for the external cylindrical body, or at least for a part thereof.
  • the constraining means are constrained in a removable manner to the external cylindrical body of the propeller, or at least to a part thereof, and comprise, according to a possible embodiment, a circular flange constrained in the part positioned at the rear of the external cylindrical body.
  • the retaining means to keep the propeller in assembled position comprise at least one elastic element, positioned between the internal cylindrical body and the external cylindrical body, or at least a part thereof, which cooperates in retaining and keeping the components of the propeller mutually assembled.
  • This elastic element is a Seeger type metal circlip, or a not open and elastically deformable metal ring, positioned at the external surface of the internal cylindrical body of the propeller.
  • the retaining means comprise, additionally to one or more elastic elements, at least one abutting surface of the lock nut on the external cylindrical body of the propeller, or on at least a part of the external cylindrical body of the propeller.
  • the nut that allows the propeller to be constrained to the motor shaft comprises a lateral skirt and the abutting surface on the external cylindrical body is positioned at the end of this lateral skirt.
  • all the components of the propeller remain in assembled position by means of the retaining means, and preferably by means of at least one elastic annular element and/or at least one abutting surface of the nut, cooperating with the internal cylindrical body of the propeller.
  • the constraining means with which the propeller is provided also allow the nut for locking the propeller to the motor shaft to be kept in assembled position, and in particular, coupled with at least part of the external cylindrical body of the propeller, In this manner, during removal of the propeller, even if loosened, this nut will remain coupled with the external cylindrical body.
