A spiral joint, also known as a helical joint, is a mechanical connection that enables rotational movement between two components. This type of joint utilizes a spiraling or helical design, allowing for smooth and seamless rotation. Synonyms for spiral joint include twisted connection, coiled coupling, and helix linkage. These terms describe the repetitive winding or twisting nature of the joint, indicating its ability to twist and rotate effortlessly. Be it in mechanical engineering, fluid dynamics, or other industries where rotational movements are crucial, these synonyms emphasize the fundamental concept of a spiral joint, highlighting its elegance and efficiency in facilitating rotational motion.
