Description

Technical Field

[0001] This utility model relates to small vessel technology, and more particularly to an outboard motor angle lock structure. Background Technology

[0002] Currently, a propeller is a device that converts engine power into propulsion by rotating blades in air or water. It typically has two or more blades connected to a hub, with the rearward-facing surface of the blades being a helical or nearly helical surface. Propellers come in many types and have a wide range of applications, such as propulsion systems for airplanes and ships.

[0003] Patent document with application number "CN201310626569.4" discloses a radial turbulence-resistant ship propeller. One to two turbulence-resistant strips are integrally formed on each propeller blade. These strips include blade-surface turbulence-resistant strips and blade-back turbulence-resistant strips. The centerline of each strip is a spatial helix with radius R2 and the propeller shaft axis as the center. Compared to ship propellers without turbulence-resistant strips, this invention offers several advantages. The turbulence-resistant strips effectively reduce the speed and extent of radial turbulence on the propeller blade surface, reduce blade tip cavitation, reduce vibration, noise, and whistling, improve efficiency, and thus save energy. Simultaneously, they enhance the comfort of shipboard living and, for naval vessels, improve their stealth capabilities.

[0004] Patent document with application number "CN200710146668.7" discloses a marine propeller with excellent wear resistance. The marine propeller of the present invention comprises a propeller body (27b) formed by casting aluminum alloy having a blade portion and a hub portion, and an anodized film (27c) provided to cover the surface of the propeller body, wherein the anodized film (27c) is obtained by anodizing the surface of the propeller body after grinding.
