To provide a vessel propulsion apparatus capable of absorbing a bidirectional torque fluctuation.SOLUTION: A torque fluctuation absorbing mechanism TFA includes a first outer helical spline 31, an intermediate member 4, an outer member 5, a first spring 6, and a second spring 7. The first outer helical spline 31 rotates integrally with a torque transmission shaft TT. The intermediate member 4 is movable in a first axial direction X1 and in a second axial direction X2. The intermediate member 4 is linked with the torque transmission shaft TT through a first helical spline coupling HC1 including the first outer helical spline 31. Axial movement of the outer member 5 with respect to the torque transmission shaft TT is regulated. The outer member 5 is linked with the intermediate member 4 through a second helical spline coupling HC2. The first spring 6 biases the intermediate member 4 in the first axial direction X1. The second spring 7 biases the intermediate member 4 in the second axial direction X2.SELECTED DRAWING: Figure 7
【課題】双方向のトルク変動を吸収できる船舶用推進機を提供する。【解決手段】トルク変動吸収機構TFAが、第1アウタヘリカルスプライン31と中間部材4とアウタ部材5と第1ばね6と第2ばね7とを含む。第1アウタヘリカルスプライン31はトルク伝達軸TTと一体回転する。中間部材4は、第1軸方向X1および第2軸方向X2に移動可能である。中間部材4は、第1アウタヘリカルスプライン31を含む第1ヘリカルスプライン結合HC1を介してトルク伝達軸TTと連結される。アウタ部材5は、トルク伝達軸TTに対する軸方向移動が規制される。アウタ部材5は、第2ヘリカルスプライン結合HC2を介して中間部材4と連結される。第1ばね6は、中間部材4を第1軸方向X1に付勢する。第2ばね7は、中間部材4を第2軸方向X2に付勢する。【選択図】図7
