Claims (1)
プロペラと、該後方プロペラの前方で上記プロペラ軸に
遊嵌され後方プロペラと逆方向に回転する前方プロペラ
とからなる二重反転プロペラにおいて、上記前方プロペ
ラのボスと後方プロペラのボスの対向する面に環状に歯
を刻設し、該両歯に噛合して後方プロペラの回転トルク
を前方プロペラへ伝達する中間歯車を上記両プロペラ間
に介装し、該中間歯車を支持杆を介して船体に係止した
ことを特徴とする二重反転プロペラ。A contra-rotating propeller consisting of a rear propeller fixed to the tip of a propeller shaft and interlocking with the propeller shaft, and a front propeller that is loosely fitted to the propeller shaft in front of the rear propeller and rotates in the opposite direction to the rear propeller. Teeth are carved in an annular shape on opposing surfaces of the boss of the propeller and the boss of the rear propeller, and an intermediate gear is interposed between the two propellers, which meshes with the teeth and transmits the rotational torque of the rear propeller to the front propeller. A counter-rotating propeller, characterized in that the intermediate gear is locked to a ship's hull via a support rod.
