Abstract

In one aspect of the invention, a motorized machine comprises at least one rotary assembly supported by a frame of the machine. A rotary drive device is disposed within an inner diameter of the rotary assembly. The rotary drive device is configured to rotate the rotary assembly with respect to the frame.

Claims (27)

1 . A motorized machine, comprising:

at least one rotary assembly supported by a frame of the machine;

a rotary drive device disposed within an inner diameter of the rotary assembly; and

the rotary drive device is configured to rotate the rotary assembly with respect to the frame.

2 . The machine of claim 1 , wherein the rotary assembly is a degradation drum with a plurality of cutting elements.

3 . The machine of claim 1 , wherein the rotary assembly is a compactor.

4 . The machine of claim 1 , wherein the rotary drive device is an electric motor.

5 . The machine of claim 1 , wherein the rotary drive device is interlocked within an inner diameter of the rotary assembly.

6 . The machine of claim 1 , wherein the rotary drive device is an axial vector engine.

7 . The machine of claim 1 , wherein the rotary drive device is a wankel engine.

8 . The machine of claim 1 , wherein the rotary drive device comprises a connecting rod that connects to the inner surface of the rotary assembly.

9 . The machine of claim 1 , wherein the rotary drive device comprises a gear set that connects to the inner surface of the rotary assembly.

10 . The machine of claim 1 , wherein the rotary drive device is a hydraulic motor.

11 . The machine of claim 1 , wherein the degradation drum further comprises a hydraulic reservoir.

12 . The machine of claim 11 , wherein the hydraulic reservoir is connected to a hydraulic circuit supported by the frame of the machine.

13 . The machine of claim 1 , wherein the rotary drive device is in electrical communication with a power source supported by the frame of the machine via an electrically conductive medium.

14 . The machine of claim 13 , wherein the electrically conductive medium comprises a swivel joint located along a rotational axis of the rotary assembly.

15 . The machine of claim 1 , wherein the rotary assembly weighs at least 30 percent of the total weight of the motorized machine.

16 . The machine of claim 15 , wherein the machine comprises a light weight truss that supports the assembly, the truss comprising carbon fiber, aluminum, aerogels, metal matrix composites, or combinations thereof.

17 . The machine of claim 1 , wherein the rotary drive device is controlled by an operator via a control panel, remote control, or combinations thereof.

18 . The machine of claim 1 , wherein the rotary drive device is powered by an external power source.

19 . A milling machine, comprising:

at least one milling drum supported by a frame of the machine;

an engine disposed within an inner diameter of the drum;

the engine being configured to rotate the drum with respect to the frame;

a combined weight of the engine and the drum being amounting to at least half of the total weight of the milling machine.

20 . The machine of claim 1 , wherein the rotary drive device is held stationary with respect to the frame.
