A hub mounting assembly for mounting a plurality of impellers onto a shaft has a first hub ring and a second hub ring. A first key piece is adapted to engage with the shaft and engage with at least one of the hub rings, and a first lock pin is adapted to engage with the shaft and engage with at least one of the hub rings. In the installed state, the first hub ring is adapted to be fastened to the second hub ring, to trap the key piece and lock pin in a position so that the hub rings together form a hub that is locked against rotation and axial movement with respect to the shaft.

Sanitary removable impeller hub and method

A hub for removable mounting onto a shaft has an inner sleeve having a first end and a second end, and having a substantially cylindrical inner diameter and having an outer surface having a threaded region and a tapered conical surface located substantially near the first end. An outer hub has an inner surface with a threaded region threadably engagable with the threaded region of the inner hub, and a inner tapered conical surface configured to cam along the tapered outer surface of the inner hub. The hub can be locked at a desired axial location or the shaft by engaging the threads to cause the cam surfaces to constrict the diameter of the first end so it frictionally locks onto the shaft.

Sanitary hub assembly and method for impeller mounting on shaft

A coupling assembly that can be used to quickly connect and disconnect an impeller shaft to and from a drive output shaft. A portion of the coupling assembly can be used to secure the impeller shaft inside a mixing vessel so that the impeller shaft can remain secure inside the mixing vessel when the drive is disconnected. The coupling assembly has a first and a second coupling half, a first group of locking pens that extend from the first coupling half and can pass through openings formed in the second coupling half, and second group of locking pins that extend from the first coupling half and can pass through openings formed in the top region of the mixing vessel.
