SELF-POSITIONING FIVE-CONTACT ROTARY KINEMATICS PAIR Russian patent published in 1999 - IPC

FIELD: mechanical engineering. SUBSTANCE: this relates to joining of machinery components. Kinematic pair incorporates self-positioning three-motion kinematic pair which is made up of movable link in the form of ball interacting with three-face recess. Movable link is made in the form of two balls which are rigidly interconnected by stem. Second ball interacts with two-face trough which is integral with three-faced recess. Aforesaid embodiment of kinematic pair prevents turning of movable link relative to axes which are perpendicular to axes of preset rotation. EFFECT: higher efficiency. 1 dwg
