(57) [Abstract] [Purpose] Involved in propulsion blades (screws, propellers) of ships, aircraft, rotorcraft, etc., and projected perpendicularly to the propulsion rotor surface of the screw with a radius from the axial center of the screw. A single line or multiple rows of propulsion stabilizing ribs are integrally provided in the direction of rotation for the role of straight line propulsion so that there is no rolling (longitudinal or horizontal shaking) in either direction from the axial center to the straight line. An object of the present invention is to provide a screw that can perform stable propulsion, prevent the load from collapsing, improve propulsion performance, steering performance, and stability performance, and can perform safe and stable propulsion. [Structure] Radius R1 based on the axial center of the screw,
R2, R3 ...- The propulsion rotor blade surface (0
A screw having a structure in which a propulsion stabilizing rib (01) is provided in a circular shape protruding perpendicularly to 2) and in a rotational direction in a single row or a plurality of rows.
Description
この実用新案は、特に船舶や航空機、ヘリコプターなどの推進翼（スクリュー 、プロペラ）に関わり、推進物体が安定して一直線性の推進ができる事を目的と するスクリューを提供するものである。 スクリューの軸芯を基点にしての半径Ｒ１、Ｒ２、Ｒ３・・で This utility model is concerned with propulsion blades (screws, propellers) of ships, aircraft, helicopters, etc. and aims to provide a screw for the purpose of stably propelling a propelling object in a straight line. With radii R1, R2, R3 ...
【図３】に示す 如く円形状に且つ矢印ＲＶの回転方向に単列または複数列にスクリューの推進負 荷側の推進回転翼面（０２）に垂直に突起した推進安定リブ（０１）を設けてあ り、前記ＲＶの回転方向において、軸芯から放射状のいづれの方向にもローリン グ（縦、横揺れなど）をせずに一直線性の推進ができるため、積み荷の荷崩れを 防止し、推進性能、操縦性能と安定性能を向上させ、安全で且つ安定した推進を 可能にして、従来のスクリューの様相を完全に変貌するスクリューを提供するこ とを特徴とします。As shown in FIG. 3, a propulsion stabilizing rib (01) is provided in a circular shape and in a single row or in a plurality of rows in the rotational direction of arrow RV, the propulsion stabilizing rib (01) protruding perpendicularly to the propulsion rotor blade surface (02) on the propulsion load side of the screw. In the rotation direction of the RV, straight line propulsion can be performed without rolling (longitudinal or horizontal shaking) in any of the radial directions from the axis, preventing the load from collapsing. It features a screw that improves propulsion performance, steering performance and stability, enables safe and stable propulsion, and completely transforms the aspect of conventional screws.
