Rotor support of different diametric sections

Abstract

The milling machine 50 includes a frame 12 and a milling assembly 20 coupled to the frame. The milling assembly 20 including a rotor housing 28 and a cutting rotor 22, the cutting rotor 22 includes a rotor shell 100 and a spindle 110, and a plurality of different diameter rings 202, 204, 206 arranged on the inner surface 208 of the rotor shell 100 at a drives side 120 of the rotor shell 100 and a corresponding plurality of different diameter rings 212, 214, 216 arranged on a outer surface 218 of the spindle 110 at a drive side 120 of the spindle 110. Wherein when the rotor shell 100 is mounted on the spindle 110 the plurality of different rings 202, 204 206 of the inner surface 208 of the rotor shell 100 contact the corresponding plurality of different diameter rings 212, 214, 216 of the outer surface 218 of the spindle 110.
