THREE-CONTACT KINEMATIC COUPLE Russian patent published in 2003 - IPC

FIELD: mechanical engineering, in particular, machine part connections. SUBSTANCE: three-contact kinematic couple has two links. First link is made in the form of washer with convex side surface. Second link is made in the form of surface with two cylinders rigidly fixed thereon. One contact of kinematic couple is defined by planar surfaces of both links and two other contacts are defined by convex side surface of first link and generatrices of cylinders on second link. Construction of kinematic couple provides for tree-contact engagement of two links for effecting only rotational motion and, if needed, of progressive motion. EFFECT: increased efficiency and simplified construction. 1 dwg
