Endless belt assembly with improved insert coupling
Abstract
Abstract AN IMPROVED CONTINUOUS BELT ASSEMBLY SUITABLE FOR USE IN HIGH VELOCITY, MODERATE-LOAD POWER TRANSMISSION APPLICATIONS COMPRISING, IN COMBINATION, A NOVEL INTERNAL COUPLING MEANS AND A TOUGH EXTENSIBLE, FLEXIBLE AND TEAR RESISTANT POLYMERIC BELTING. THE COUPLING MEANS INCLUDES A CYLINDRICAL SHANK WITH A CONTINUOUS, CIRCULAR, EXTERNAL RIB HAVING AN OUTER HOLDING EDGE, PROXIMATE EACH OPPOSITE END THEREOF, SUCH EDGES BEING ADAPTED TO CUT INTO AND GRIP THE INTERIOR WALLS OF THE BELTING WHEN THE COUPLING MEANS IS INSERTED INTO HOLLOW ENDS OF THE BELTING AND THE BELTING IS SUBSEQUENTLY MOUNTED ON MACHINERY. WHEN MADE OF RIGID MATERIAL, THE SHARP EDGES ARE JOINED BY A CONNECTOR SHANK, OR SHAFT OF AT LEAST ABOUT 20% LARGER THAN THE INSIDE DIAMETER OF THE HOLLOW TUBULAR BELTING, THUS PROVIDING MEANS FOR MAINTAINING THE OUTER DIAMETER OF THE ELASTOMERIC BELT UNIFORM BETWEEN THE POINTS AT WHICH THE AFORESAID SHARP EDGES CUT INTO THE BELT. WHEN MADE OF FLEXIBLE MATERIAL, THE DIAMETER OF THE CONNECTOR SHANK OR SHAFT MAY BE EQUAL TO THE INSIDE DIAMETER OF THE TUBING.
