Abstract

THE FRICTION MECHANICS OF VERY HIGH LOADED SLIDING AREA BETWEEN PISTON AND CYLINDER OF TILTED PLATE AXIAL PISTON MACHINES USED IN HYDROSTATICS HAVE BEEN EXPLORED.THIS REQUIRED AT FIRST THE DEVELOPMENT OF A NEW TEST STAND FOR THE DIRECT MEASUREMENT OF THE FRICTION FORCES.THE EXPERIMENTAL RESULTS CONFIRMED THE THEORETICAL EXPECTATIONS.THE FRICTION LOSSES FOLLOW THE LAWS OF THE STRIBECK CURVE, I.E.HIGH FRICTION IN THE STARTING PHASE, DECREASING FRICTION WITH INCREASING SPEED OF ROTATION UP TO A MINIMUM (RANGE OF MIXED FRICTION WITH IMPERFECT FLUID FILM) AND THEN SMOOTHLY INCREASING FRICTION AGAIN (RANGE OF FULLY DEVELOPED FLUID FILM LUBRICATION).RELATED TO THIS BEHAVIOUR, IT WAS POSSIBLE TO CONFIRM AN IMPORTANT SIMILARITY PARAMETER (TAKEN FROM JOURNAL BEARING THEORY) WHICH SUMMARISES THE INFLUENCES OF DYNAMIC OIL VISCOSITY, SPEED OF ROTATION AND LOAD.FURTHER EXPERIMENTS CONCERNED KINEMATIC AND GEOMETRICAL INFLUENCES.THE RESULTS ARE SO PRESENTED AS TO MAKE AVAILABLE A WHOLE RANGE OF RULES FOR OPTIMAL DESIGN OF THE INVESTIGATED PISTON-CYLINDER SLIDE PAIRING.(A.)
