Abstract
A drum for a roller compactor has an outer shell providing an exterior peripheral compacting surface and an interior for housing an excitation system used to vibrate the drum. The outer shell includes a non-elastic polymer with embedded reinforcing fibers.
Claims19
A drum for a roller compactor, comprising:
- an outer shell providing an exterior peripheral compacting surface;
- and
- an interior for housing an excitation system used to vibrate the drum,
- wherein the outer shell comprises:
- a non-elastic polymer;
- reinforcing fibers embedded within the non-elastic polymer;
- and
- at least one reinforcing component at least partially embedded within the non-elastic polymer.
5 more elements
A roller compactor, comprising:
- at least one drum configured to compact construction materials, the drum comprising:
- an outer shell providing an exterior peripheral compacting surface,
- wherein the outer shell comprises a polymer with reinforcing fibers;
- and
- an excitation system at least partially within the outer shell for vibrating the drum,
- the excitation system comprising an eccentric mass whose moment is selected based upon a mass of the drum.
3 more elements
A method of making a drum for a roller compactor, comprising:
- performing an additive manufacturing process to build an integral, one-piece drum body from a fiber reinforced polymer, the drum body comprising an outer, substantially cylindrical shell with at least one head plate extending from an interior surface of the shell;
- pausing the additive manufacturing process prior to completion of the drum body;
- adding one or more reinforcing components to the partially completed drum body;
- completing the additive manufacturing of the drum body, wherein the one or more reinforcing components is at least partially embedded within the drum body.
