MECHANISM FOR CONVERTING ROTARY MOTION INTO INTERMITTENT ROTARY AND RECIPROCATING MOTION Russian patent published in 2002 - IPC

FIELD: mechanical engineering. SUBSTANCE: invention can be used as hydromechanical system for robotic devices, for instance, flexible manufacturing systems. Proposed mechanism has housing accommodating two mechanically coupled intermediate shafts on one of which Geneve wheel is mounted. Driven shaft is spring-loaded relative to housing and is connected with second intermediate shaft for relative displacement. Driven shaft consists of two parts connected by universal joint. Mechanism is furnished with additional cam mechanically coupled with driving shaft. Pusher of additional cam is hinge-coupled with driven shaft and is installed for rotation around driven shaft axis. Pusher is secured on kinematic member, and additional cam is made enclosing relative to driven shaft axis. Driving shaft is mechanically coupled with auxiliary adjustable drive installed in housing. One of outlet members of drive is mechanically connected with additional cam. The latter is installed for reciprocating along driven shaft axis owing to provision of telescopic mechanically connected shafts. Additional cam is mounted on one of these shafts, and kinematic member mechanically coupled with driving shaft is mounted on other telescopic shaft. Other outlet members, in their turn, are connected with cam and pusher, being made adjustable. Outlet members are connected with movable parts by means of which adjustment is carried out in process of mechanism operation. Carrier and cam are coupled with installed for travel together with cam and releasing of carrier pin or engaging the pin with Geneva wheel. EFFECT: possibility of use of proposed mechanism as hydromechanical system of reprogrammable robot operating as automatic manipulator. 2 cl, 7 dwg
