Abstract
A fluid-driven ring saw includes a ring saw blade that is supported and driven by a fluid. The fluid-driven ring saw can include one or more pairs of fluid nozzles. Each pair of fluid nozzles can include a first fluid nozzle separated from a second fluid nozzle by a gap. The ring blade can be positioned within the gap. The ring blade can include a plurality of holes. The one or more pairs of fluid nozzles can deliver fluid jets that impinge upon the plurality of holes of the ring blade to drive rotation of the ring blade. The ring blade can be driven without direct contact of a mechanical linkage, such as a belt or chain. The ring blade can be relatively thinner than ring blades driven by mechanical linkages.
Claims21
A fluid-driven ring saw comprising:
- a housing comprising one or more pairs of fluid nozzles, wherein each pair of fluid nozzles comprises a first fluid nozzle separated from an opposite second fluid nozzle by a gap;
- and
- a ring blade positioned within the gap, the ring blade comprising:
- an annular body having an outer edge, an inner edge, a first peripheral side, and a second peripheral side, and
- a plurality of holes positioned around the annular body, each hole extending through the annular body from the first peripheral side and the second peripheral side,
- wherein the one or more pairs of fluid nozzles are configured to deliver fluid jets that apply forces to surfaces of the plurality of holes of the ring blade to drive rotation of the ring blade.
A saw blade that is configured to be driven by a fluid, the saw blade comprising:
- an body having an outer edge, an inner edge, a first peripheral side, and a second peripheral side, wherein a thickness of the saw blade, measured between the first peripheral side and the second peripheral side, is less than 0.02 inches;
- and
- a plurality of cutouts positioned around the body, each of the plurality of cutouts extending through the body from the first peripheral side and the second peripheral side, each of the plurality of cutouts comprising an annular opening formed on the first peripheral side and the second peripheral side and a cylindrical inner surface defining the each of the plurality of cutouts.
A method for driving rotation of a blade of a ring saw, the method comprising:
- directing fluid jets into a plurality cutouts on the blade of the saw to support and drive rotation of the blade without the use of a direct mechanical linkage connecting to the blade;
- and
- suspending the blade, while driving rotation of the blade, via the fluid jets being directed into the plurality of cutouts.
