ROTARY MECHANICAL DEVICE Russian patent published in 1995 - IPC

FIELD: mechanical engineering. SUBSTANCE: rotary mechanical device has at least two uniaxial casings. They are mounted for turning in complanar planes and are interconnected by kinematic coupling. In compliance with one version kinematic coupling is manufactured in the form of gear rings placed coaxially and directed in opposition with their teeth, driving member and at least two ratchet pawls. In agreement with the other version kinematic coupling is fabricated in the form of gear ring, rotary member and at least one ratchet pawl. With turning of driving member to one or the other side one casing turns relative to the other one or both casings turn together. EFFECT: simplified design, simplification of operations of turning of optical elements. 6 cl, 6 dwg
