Abstract
A mobile milling machine includes a cutting rotor disposed along a rotor drum delineating a drum rotation axis and accommodated in a rotor chamber delineated by chamber enclosure. To rotatably support the rotor drum with respect to the chamber enclosure, the rotor drum can include a bearing end and the chamber enclosure can include a bearing bore that are adapted to form a drum bearing assembly. The drum bearing assembly may include a bearing hub and a bushing configured to make a sliding frictional contact along complementary taper surfaces. The floating bushing may be floatingly retained in a chamber door of the chamber enclosure.
