HYDRAULIC WINCH Russian patent published in 2004 - IPC

FIELD: mechanical engineering; load lifting devices. SUBSTANCE: invention can be used in mechanisms of winches powered by high-torque hydraulic motors. Winch contains shaft installed on bearing supports which carries cable drums, pressure rollers mounted on axles for rotation and at least one high-torque hydraulic motor mechanically coupled with shaft. Roller supports are made in form of leaf springs some ends of which are rigidly coupled with roller axles and other ends are rigidly coupled with frame. Mechanical coupling of hydraulic motor and shaft is provided by rotor installed directly on which shaft. Stator of hydraulic motor is coupled with winch frame by means of lever rigidly connected with stator, and guide hinge-coupled with lever and frame. EFFECT: increased efficiency, improved reliability in operation, simplified design. 2 dwg
