An assembly for transmitting power to an appliance, is disclosed. The appliance is placed upon a counter top that defines an aperture. The assembly includes an electric motor, a rotatable shaft driven by the electric motor, and a drive mechanism removably coupled to the rotatable shaft. The electric motor and the rotatable shaft are located below a first side of the counter top and are hidden from view. The drive mechanism is removably coupled to the rotatable shaft. The drive mechanism includes a first portion removably coupled to the rotatable shaft and a second portion that defines a drive socket shaped to receive a male portion of the appliance. At least a portion of the drive mechanism extends through the aperture in the counter top and is located above a second side of the counter top.

A method for producing a shaft-hub connection having a secondary bearing seat that is on the shaft and that is axially at a distance from the shaft-hub connection includes determining a dimensional deviation relative to a final dimension of the bearing seat as a derivative action for a deformation of the bearing seat. A final machining of the bearing seat is performed with the dimensional deviation before assembly of the shaft-hub connection. Then, the shaft-hub connection is produced by a press-fit connection. The deformation of the shaft caused by the shaft-hub connection deforms the bearing seat to the final dimension, in that the deformation of the shaft compensates for the dimensional deviation of the bearing seat.
