Abstract
A rotary member () of an endless loop power transmission system can have a hub () for a centered connection to a shaft. The hub () can have a central aperture () extending therethrough and a plurality of radially inwardly projecting and axially extending flutes () formed on an inner circumferential surface () of the central aperture () defining reduced circumferential surface areas () for machining a central bore () through the hub (). An interrupted finishing machining cut along the reduced circumferential surface areas () of the central aperture () provides increased coolant flushing, while reducing finishing machining cycle times, and reducing load and wear on a bore cutter.
