ABSTRACT:
The connector includes a flanged clamping ring and an unflanged clamping ring. One ring is received within the other. Tightening screws tighten the connector by drawing the rings together in axial direction. Each ring has an inner and an outer surface. The inner surface of the outer ring and the outer surface of the inner ring are conical surfaces which engage each other when the rings are drawn together in axial direction. The other surface of at least one of the rings is a clamping surface adapted to engage with a clamp action a complementarily configurated surface of a shaft or collar when the rings are drawn together in axial direction. The unflanged ring at the axial end thereof facing towards the flange is provided, intermediate the inner surface of the unflanged ring and the outer surface of the unflanged ring, with an inclined conical intermediate surface. The flange has an inner surface which faces towards and is substantially parallel to the inclined conical intermediate surface of the unflanged ring.
