Fluid-driven ring saw

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.

本流体驱动环锯（fluid-driven ring saw）包含由流体支撑并驱动的环锯刀片（ring saw blade）。该流体驱动环锯可配置一对或多对流体喷嘴（fluid nozzles）：每对流体喷嘴均由间隔间隙分隔的第一流体喷嘴与第二流体喷嘴组成，环锯刀片可容纳于该间隙中。环锯刀片开设有多个通孔，所述多对流体喷嘴可喷射流体射流（fluid jets），冲击环锯刀片的多个通孔以驱动其旋转。该环锯刀片无需皮带、链条等机械联动装置（mechanical linkage）直接接触即可实现驱动，且相较于采用机械联动装置驱动的环锯刀片，其厚度相对更薄。
