Abstract
A milling machine can include a frame, a milling assembly coupled to the frame, the milling assembly including a rotor housing and a cutting rotor, the cutting rotor including a rotor shell positioned around a spindle, and a removable support ring positioned on an inner surface of the rotor shell, wherein the support ring is positioned between the rotor shell and the spindle, wherein the support ring is separate from the rotor shell and carries a load of the rotor shell from the spindle.
Claims20
A milling machine comprising:
- a frame;
- a milling assembly coupled to the frame, the milling assembly including a rotor housing and a cutting rotor, the cutting rotor including a rotor shell positioned around a spindle;
- and
- a removable support ring positioned on an inner surface of the rotor shell, wherein the support ring is positioned between the rotor shell and the spindle, wherein the support ring is separate from the rotor shell and carries a load of the rotor shell from the spindle.
A milling assembly comprising:
- a cutting rotor and a rotor housing, the cutting rotor including a rotor shell positioned around a spindle;
- and
- a removable support ring positioned on an inner surface on a drive side of the rotor shell, wherein the support ring is positioned between the rotor shell and the spindle, wherein the support ring is separate from the rotor shell and carries a load of the rotor shell from the spindle, wherein the rotor shell and the spindle do not articulate against each other such that the support ring is a load carrying surface and not a bearing surface.
A method of mounting a rotor shell to a spindle of a cutting rotor of a milling machine, the method comprising:
- attaching a removable support ring to an inner surface of a rotor shell;
- and
- positioning the rotor shell over a spindle such that the support ring is positioned between the rotor shell and the spindle, wherein the support ring is separate from the rotor shell and carries a load of the rotor shell from the spindle.
