BED TO MEASURING VIBRATIONS OF OUTPUT LINK OF CAM-GEAR-LEVER MECHANISM Russian patent published in 1996 - IPC

FIELD: mechanical engineering, experimental studies. SUBSTANCE: invention is aimed at experimental study of dynamics of cam-gear-level and gear-level mechanisms of single-side intermittent motion of output link. Bed for this purpose incorporates two mechanism placed in parallel one above other having equal lengths of links, number of teeth and common driving crank. Each mechanism includes four-bar linkage, four gears put on axle of joints of four-bar linkage. One of them is rigidly coupled to crank and two gears are put on mobile joint of rocker. One interacts with gear rigidly coupled to crank, the other one - with output gear placed on to immobile joint of rocker. One mechanism is additionally fitted with restoring element two-way preload intercoupling two gears freely mounted on to mobile joint of rocker and capable of turning with reference to each other. It has fixing arm interacting both with cam put on rotation axle of crank and rigidly coupled to it and with output gear of mechanism. Gears put on mobile joint of rocker in the other mechanism are rigidly intercoupled. EFFECT: expanded range of experiments. 8 dwg
