萬向接頭（U型接頭）

A univeal joint (U-joint) is a mechanical coupling connecting two shafts, enabling them to rotate in different directio while tramitting torque. Comprising two yokes and a cross-shaped member, it accommodates angular misalignment through its flexible design. Primarily used in automotive drivetrai, industrial machinery, and agricultural equipment, U-joints excel in scenarios requiring torque tramission and flexibility. In vehicles, they feature prominently in propeller shafts, steering systems, and marine applicatio. Industrial machinery benefits from U-joints in conveying and manufacturing systems. Their ability to smoothly tramit power despite misalignments makes them essential components in various mechanical systems, providing veatility in power tramission while accommodating angular variatio between connected components.
