Higher kinematic pair that converts rotary motion into helical motion is presented as an alternative to the screw joint which is a lower kinematic pair. First, the existence of a rolling (and hence desmodromic) transmission pair for a rotary to helical motion conversion is proven. Then, the corresponding pair of rolling surfaces and the position relative to each other is defined, and depends on the kinematic parameters of the transmission. Finally, a MATLAB ® code that calculates these surfaces for a given set of transmission parameters, and some examples are presented.
