THREE-DEGREE-OF-FREEDOM KINEMATIC PAIR Russian patent published in 2014 - IPC F16S5/00 

FIELD: machine building.

SUBSTANCE: invention relates to machine building and can be used to couple the members of mechanisms. A three-degree-of-freedom kinematic pair comprises two members (1 and 2) with geometrical elements in the form of cylindrical surfaces getting in lined contact. The geometrical elements of the pair are made as a male and female faces interacting with each other. The male face of the member (1) is made as a straight circular cylinder of specified diameter, and the female face of the second member (2) is made as a through curved groove. The groove height is equal to the diameter of the first member cylinder and the groove length is less than the cylinder length.

EFFECT: provision for required set of motions.
