摘要：
In a milling drum (2) for a construction machine, in particular a road milling machine (1) or a recycler, with an interchangeable milling tube (4) arranged coaxially to the axis (20) of the milling drum, where the milling tube (4) is supported, by means of a support ring (8), on a support ring mount (12) of a rotating body coupled to a milling drum drive (16), it is provided that the support ring (8) and the support ring mount (12) of the rotating body display several complementary supporting surfaces (22, 24) arranged coaxially to the axis (20) of the milling drum, where the said supporting surfaces (22, 24) have different supporting circle diameters and are arranged behind one another axially with their diameters decreasing incrementally in the pulling direction.
