Circumferential channel is diffused.
Further, the fair water cone body is disposed radially mounting hole, and the mounting hole communicates with the through hole, the stern tube shaft
It is upper that the screw that is adapted with mounting hole is set so that fair water cone body is socketed on stern tube shaft, can by external bolt through mounting hole,
Screw is engaged, and fair water cone is fixed on stern tube shaft, and fair water cone is with stern tube shaft synchronous axial system when stern tube shaft rotates.
Further, the aft edge of the stub end of the fair water cone body sets chamfered section so that the tail of fair water cone body
Seamlessly transitted between end margin and stern tube shaft.
Further, the fair water cone body is by polytetrafluoroethylplastic plastic integrated injection molding, and corrosion-resistant, coefficient of friction is small.
The technique effect of utility model：（1）Yacht stern tube shaft fair water cone of the present utility model, relative to prior art,
The fair water cone of truncated cone-shaped is set before propeller so that current meet obstructions when axially flowing, and are spread to radial direction, realization point
Dissipate the purpose of water conservancy diversion；（2）The setting of water conservancy diversion conduit and circumferential channel so that circumferentially groove when current flow through the tail end of water conservancy diversion conduit
Road is diffused, and reduces axial resistance of the current to propeller, improves the efficiency of propeller；（3）Fair water cone body is by polytetrafluoro
Vinyl plastics integrated injection molding, corrosion-resistant, coefficient of friction is small.
Brief description of the drawings
The utility model is described in further detail with reference to Figure of description：
Fig. 1 is the assembling schematic diagram of yacht stern tube shaft fair water cone and stern tube shaft of the present utility model.
In figure：Stern tube shaft 1, propeller 2, gear-box 3, fair water cone body 4, small head end 41, stub end 42, water conservancy diversion conduit 43,
Circumferential channel 44, mounting hole 45, chamfered section 46.
Embodiment
Embodiment 1 is as shown in figure 1, the yacht stern tube shaft of the present embodiment is included by polytetrafluoroethylplastic plastic one with fair water cone
The fair water cone body 4 of injection molding, fair water cone body 4 are in truncated cone-shaped, including small head end 41 and stub end 42, the fair water cone body
