kardán
Kardán, in Hungarian usage, most commonly refers to the Cardan joint, also known as a universal joint, a mechanical linkage used to transmit torque between two shafts that are inclined relative to each other. It consists of two yokes connected by a cross-shaped intermediary (the spider). As the input shaft rotates, the output shaft follows, but the angular velocity is not constant unless the shafts are aligned or two joints are used with proper phasing.
In terms of kinematics, a single Cardan joint at an angle beta relates the input angle and
The term kardán derives from Cardano, Girolamo Cardano, the 16th‑century Italian mathematician after whom the device
Other uses of the term in Hungarian technical vocabulary include generic references to universal joints or
