Device for connecting a centerless auger to a rotatable member

摘要

An auger assembly according to one example embodiment includes an auger having a helical flight extending along a longitudinal axis. The auger has a central opening running along the longitudinal axis. The auger has an end that includes at least a portion of a turn having substantially zero pitch. A retaining member has a body including a groove on an outer surface of the body. The groove has a shape complementary to the helical flight at the end of the auger. At least a portion of the end of the auger is retained within the groove. A rotatable coupling member extends along the longitudinal axis. At least a portion of the rotatable coupling member is positioned within the central opening of the auger and presses the outer surface of the retaining member against an inner diameter of the end of the auger.
