Patent ID: 7475467

Claim:
A method of making a rotor for a threshing system of an agricultural combine, comprising steps of: providing an inlet segment having a rigid lip centered about a rotational axis, the lip having a predetermined shape and an axially tapered peripheral surface having a first predetermined transverse dimension measured through the rotational axis; providing a tubular main body segment having a first open end portion and a second open end portion, the first open end portion being configured and sized to be press fit to the tapered peripheral surface of the lip of the inlet segment concentric about the rotational axis, and the first open end portion of the tubular main body segment being configured and sufficiently compliant so as to be conformable to the predetermined shape and transverse dimension of the lip when press fit thereto; providing a disk shaped bulkhead including a center hub having a central axis therethrough and an outer skirt extending around the hub and centered about the axis therethrough, the outer skirt being configured to be press fit to the second open end portion of the main body segment; and assembling the inlet segment, the main body segment, and the bulkhead together, by press fitting the first open end portion of the main body segment onto the lip of the inlet segment so as to conform thereto, and by press fitting the skirt of the bulkhead to the second open end portion of the main body segment, such that the bulkhead, the main body segment and the inlet segment are concentric about the rotational axis.
