This study evaluated a new coupling system for low rotation and minimal power transmission from an electric drive to a propeller in fish ponds, focusing on performance across various bend angles and rotational speeds while measuring noise generation. The methodology included using brass and polyethylene shafts tested with and without grease at rotational speeds up to 2200 RPM. Findings revealed that the bend angle significantly impacts performance, establishing a maximum operational angle of 25 degrees for effective power and rotation transmission, and that grease application results in a 2% noise reduction, underscoring lubrication's importance in enhancing system efficiency and reducing noise. Brass was found inadequate for high-load applications despite its noise reduction and corrosion resistance advantages, suggesting carbon steel with medium carbon content as a superior alternative, given its strength and wear resistance properties. The study emphasizes the need for further research to explore energy losses and environmental impacts to optimize transmission systems in aquatic environments. Future work should also focus on developing specialized design strategies that consider shaft diameter, support spacing, friction resistance, and temperature management for improved long-term performance and reliability.
