ABSTRACT:
A rotary body fixing device capable of mounting and removing a rotary body on a shaft easily and rapidly. The device has inner and outer elastically deformable rings and a pair of oppositely tapered rings for wedging between the inner and outer rings in a clamping position. Extraction bolt holes 4F for threaded engagement with extraction bolts 7 are formed axially through one tapered ring 4. The extraction bolts 7 come into abutment at their tip ends against an end face of the other tapered ring 5 to move both tapered rings away from each other. In an axially medial part of the outer peripheral surface of the inner ring 2 and of the inner peripheral surface of the outer ring 3, annular grooves respectively form stepped portions on both sides of the annular groove. At or adjacent the opposite ends of the paired tapered rings, retaining flange portions engage the stepped portions when the rings are displaced outwardly a predetermined distance from the clamping position so that outward displacement of the retaining flange portions is limited by the stepped portions. Registering annular cylindrical flats are provided between the flanges and the tapered surfaces of the tapered rings, and between the grooves and the tapered surfaces of the inner and outer rings.
