OPPOSITE SLIDER-CRANK MECHANISM Russian patent published in 2000 - IPC

FIELD: mechanical engineering. SUBSTANCE: opposite slider-crank mechanism has support with rectilinear guide, two identical sliders installed in support, double-arm crank with axle of rotation fixed on support, two identical connecting rods and two identical rockers. Spherical hinge joints are used to connect connecting rods with corresponding arms of rocker and to connect both rockers with support and with connecting rods. Connecting rods are connected with corresponding sliders by means of kinematic pairs, each made for translation along flat axle arranged in connecting rod. Flat axle is square to slider guide. Kinematic pairs can rotate around relatively perpendicular axes one of which is directed square to connecting rod plane and the other coincides with longitudinal axis of slider guide. EFFECT: prevention of side pressure on crank arms and sliders. 2 cl, 3 dwg
