Combined hub, counterweight and crank arm with single piece steel body

摘要

A combination hub, counterweight and crank arm for a governor assembly in a ram air turbine is has a hub section with a cylindrical orifice, an annular collar section that surround the hub section, a counterweight section that extends out of the annular collar section and a crank arm section that extends out of the annular collar section, with all the sections formed in a single piece steel body.

主权项

1. A single piece steel body for a governor assembly in a ram air turbine that comprises:
a hub section that has a cylindrical hub orifice passing therethrough, the hub orifice having an axis of rotation and the hub section extending from a first planar surface along a first radial plane normal to the axis of rotation of the hub orifice to a second planar surface along a second radial plane normal to the axis of rotation of the hub orifice; an annular collar section that surrounds the hub section between a third planar surface along a third radial plane normal to the axis of rotation and a fourth planar surface along the second radial plane, the third radial plane between the first radial plane and the second radial plane and closer to the second radial plane than the first radial plane; a counterweight section in the form of a ring segment that extends out of the annular collar section axially between the second radial plane and the third radial plane and radially between a first surface of revolution about the axis of rotation that has a diameter larger than the hub orifice and a second surface of revolution about the axis of rotation of the hub orifice that has a diameter larger than the first surface of revolution, from a fifth planar surface along a first axial plane that includes the axis of rotation of the hub orifice to a sixth planar surface along a second axial plane that includes the axis of rotation of the hub orifice that is displaced from the first axial plane by a desired angle, axially from a seventh planar surface along the third radial plane to an eighth planar surface along a fourth radial plane normal to the axis of rotation of the hub orifice, the fourth radial plane farther from the first radial plane than the second radial plane and radially from a first curvilinear surface along the first surface of revolution to a second curvilinear surface along the second surface of revolution; and a crank arm section that extends out of the annular collar section axially between the second radial plane and the third radial plane in the form of a closed cylinder, with a cylindrical bore therein having an axis of rotation generally parallel to the axis of rotation of the hub orifice, displaced from the axis of rotation of the hub orifice by a desired distance along a third axial plane that includes the axis of rotation of the hub orifice.
