FIELD: mechanical engineering. ^ SUBSTANCE: invention can be used in hoisting mechanisms, actuators of robots and manipulators, walking machines and other constructions. Proposed mechanism includes drive, transmission part and actuating part. Transmission part is made at least of two sections, each consisting of hinge unit and levers installed on hinge unit for rotation. Said hinge unit contains at least three axles or shafts whose axes of rotation lie in one plane and angles between said axes are equal. Number of axles in different hinge units of one mechanism is equal. Levers included into first and last sections are single-arm or double arm ones. Levers included into other sections are double-arm ones only. Each single lever is installed by one end for rotation on axle or shaft of hinge unit and is hinge coupled by other end with end of lever of adjacent section. Each double-arm lever is installed by its middle part for rotation on axle or shaft of hinge unit. Each lever in first section is hinge coupled by one end with end of lever of following section and by other end, with drive. Each lever in last section is hinge coupled by one end with end of lever or last but one section and is coupled with actuating part by other end of lever. On other sections each lever is hinge coupled by one end with end of lever of preceding section, and by other end, with end of lever of following section. Direction of rotation of levers of one section is opposite to direction of rotation of levers of adjacent sections. Invention is aimed at improving operating characteristics, simplifying design owing to reduction of total number of members and type of members included into articulated lever mechanism. ^ EFFECT: improved reliability, increased service life, reduced materials usage. ^ 5 cl, 12 dwg |
