13、IGNED TO BE INSTALLED IN THE DRIVE SHAFT FEMALE SPLINEPRIOR TO INSTALLING THE DRIVEN ACCESSORY. NONMETALLIC SPLINE ADAPTERS ARE INTENDED TO FITTIGHTLY IN THE FEMALE SPLINE IN WHICH THEY ARE INSTALLED. TO AVOID DAMAGING THE DRIVE SHAFTOR ACCESSORY SHAFT BEARINGS AND SEALS, THE SPLINE ADAPTERS SHOULD

14、BE PRESSED INTO THEMATING SPLINES AND THE PRESSURE SHOULD BE REMOVED AS SOON AS THE SPLINE ADAPTER IS FULLYINSTALLED.7. RETENTION AND PRELOADTHE NONMETALLIC SPLINE ADAPTERS HAVE BEEN DESIGNED TO FIT TIGHTLY IN NEW FEMALE SPLINES. THE TIGHTNESS OF THE FIT WILL DIMINISH WHEN THE NONMETALLIC ADAPTER IS

15、 INSTALLED IN WORN ORUSED FEMALE SPLINES. THE SPLINE ADAPTER HAS BEEN DESIGNED TO FIT TIGHTLY TO ACHIEVE ACOMPRESSIVE PRELOAD WHICH EXTENDS THE OPERATING TORSIONAL RANGE OF THE NONMETALLICSPLINE ADAPTER. THE TIGHT FIT ALSO PROVIDES A RESISTANCE TO AXIAL MOVEMENT WHICH AFFORDSSOME DEGREE OF RETENTION

16、. HOWEVER, THE APPLICATION GENERALLY SHOULD REQUIRE SOMEPOSITIVE METHOD OF AXIAL RETENTION OF THE PART. POSITIVE RETENTION CAN BE ACHIEVED BY AVARIETY OF METHODS INCLUDING LENGTHENING THE NONMETALLIC ADAPTER, INCORPORATION OFFLANGES IN THE ADAPTER DESIGN, AND THE USE OF SNAP OR SPIRAL LOCK RINGS TO

17、LIMIT THE AMOUNTOF AXIAL CLEARANCE.8. MATERIAL SELECTIONTHE PLASTIC SPLINE ADAPTER SHALL BE FABRICATED FROM HIGH STRENGTH, SELF-LUBRICATINGPOLYMERIC MATERIALS HAVING ULTIMATE COMPRESSIVE STRENGTHS OF A MINIMUM OF 28,000 PSI. TYPICAL MATERIALS INCLUDE THE POLYIMIDE, ARAMID AND POLYAMIDE-IMIDE RESINS,

18、 BELONGING TO THEDUPONT VESPEL AND AMOCO TORLON FAMILIES. THE PROCESS OF MATERIAL SELECTION SHOULDCONSIDER STRENGTH, FATIGUE AND AGING PROPERTIES, FLUID COMPATIBILITY, THERMAL EXPOSURE,DIMENSIONAL STABILITY, AND FORMING PROPERTIES.9. SHEAR SECTIONTHE SHAFT SHALL INCLUDE A SHEAR SECTION ALLOWING THE
