Apparatus for transforming rotary motion into linear displacement and including a slip-type coupling
Abstract
Abstract AN APPARATUS FOR CONVERTING ROTARY MOVEMENT FROM A PRIME MOVER SUCH AS A GASOLINE ENGINE OR AN ELECTRIC MOTOR, TO LINEAR MOVEMENT FOR DISPLACING A LOAD WHEREIN A ROTARY SCREW MEMBER IS MOUNTED IN A CASING AND IS EITHER AN AXIALLY SHIFTABLE NUT OR A THREADED SPINDLE. THE MOTOR CASING TERMINATES IN A PROJECTING SHAFT. A TUBULAR CASING, WITH OPENINGS IN THE WALLS FOR THE THROUGHFLOW OF AIR, IS PROVIDED BETWEEN THE SCREW CASING AND THE MOTOR CASING AND IS FLANGED TO BOTH TO PRODUCE A HOUSING SEPARATED FROM THE SCREW AND MOTOR AND RECEIVING A SLIPTYPE COUPLING, THE PARTS OF WHICH ARE CONNECTED TO THE SHAFT OF THE SCREW ASSEMBLY AND TO THE MOTOR SHAFT. A BEARING OF THE COMBINED THRUST AND RADIAL TYPE IS PROVIDED IN THE PLATE OF THE TUBULAR HOUSING BETWEEN THE COUPLING AND THE SCREW ASSEMBLY WHILE A FLEXIBLE COUPLING IS PROVIDED IN THE HOUSING SPACE BETWEEN THE COUPLING AND THE MOTOR SHAFT. THE COUPLING BODY IS PROVIDED WITH AIR-DISPLACING ELEMENTS.
