Abstract

The high-speed shaft coupling is a critical component of the power transmission system, with its safety and durability directly impacting the overall system’s stability. Traditional manufacturing methods for high-speed shaft couplings primarily involve bonding fiberglass spacers to the flange. However, there have been instances where parts of the bonded spacer detach from the lower part of the flange, potentially leading to coupling failure. This issue can result in equipment downtime and reduced safety. In this study, we propose a method to reinforce the spacer by inserting pins, aiming to improve the safety of the high-speed shaft coupling. Through structural and fatigue analyses, we verify whether this approach can maintain structural stability even if part of the bonded spacer detaches. The findings of this study are expected to enhance the reliability of high-speed shaft couplings for 6MW wind turbines and contribute to securing the long-term operational safety of the equipment.
