JOINING DOWELS REMOVING METHOD

摘要

FIELD: removal of joining dowels out of pin type joining device used for mounting blades on rotor of turbine. ^ SUBSTANCE: method comprises steps of drilling in dowel first hole having first diameter and passing in axial direction approximately along 1/3 of dowel length; drilling in dowel second hole having second diameter less than first diameter and passing in axial direction from first hole approximately along 1/2 of dowel length; drilling in dowel third hole whose diameter is equal to that of second hole and that passes from second hole in axial direction approximately along 3/4 of dowel length; removing dowel. ^ EFFECT: possibility for removing dowel without damaging rotor. ^ 5 cl, 6 dwg
