ABSTRACT:
A robotic clutch with central thrust bearing (10) having a robot adaptor (12) and robotic clutch with central thrust bearing (10) which further has a housing (18) with a housing central opening (18A) therethrough and a housing cavity (18C). The housing (18) further has a housing coupler (18D) in communication with the housing cavity (18C). A toggle breakaway (14) which has a toggle breakaway collar (14F) securely fastened thereto extending downwardly therefrom through the housing central opening (18A). The toggle breakaway (14) is securely connected to the robot adaptor (12). A thrust roller bearing (22) which has a thrust roller bearing central opening (22A) therethrough and a top thrust roller bearing (22T) is circumferentially positioned along an inner surface of the housing top (18T). The thrust roller bearing (22) further has a bottom thrust roller bearing (22B) securely connected to the toggle breakaway collar (14F). An isolation plate (26) which has an isolation plate central dowel (26A) extending upwardly therefrom rotatably positioned through the thrust roller bearing central opening (22A) within the toggle breakaway central opening (14I). The isolation plate (26) is non-rotational during use of the robotic clutch with central thrust bearing (10). A diaphragm (28) is positioned adjacent to and underneath the isolation plate (26). A pressure plate (30) is positioned adjacent to and underneath the diaphragm top (28T). A bottom plate (20) securely connected to the housing (18) having at least one bottom plate air port and at least one bottom plate vacuum port (20F) therethrough in communication with the housing cavity (18C). A biasing means positioned between the bottom plate top indent (20TA) and the pressure plate (30) functioning to maintain the diaphragm (28) in an expanded position.
