Adjustable coupling between a rotary component and a cylindrical shaft

摘要

A rotary assembly for attachment to a rotary shaft includes a rotary body; and a bore hole extending in the rotary body from one end thereof for coaxially receiving a rotary shaft. The bore hole has a longitudinal axis coinciding with a rotary axis of the shaft when received in the bore hole. A parting split defining a clearance extends in the rotary body from one end thereof. The parting split extends in a plane which contains the longitudinal axis. A slot extends in the rotary body from the parting split on either side of the bore hole. The slot defines a dividing plane which traverses the longitudinal axis and which divides the rotary body into first and second axially adjoining body parts. The bore hole extends consecutively in the first and second body parts, and the bore hole which extends in the first body part is circumferentially closed. Two clamping wings are defined in the second body part by the parting split, the slot and the bore hole extending in the second body part. Two clamping bolts pass through the second body part and traverse the parting split for tightening the clamping wings to a rotary shaft passing through the bore hole.
