Abstract:
A flexure washer bearing for enabling alternating unidirectional movement of a top plate relative to a bottom plate fastened together by a fastening means extending through the flexure washer bearing for providing a loading force on the top plate relative to the bottom plate, the flexure washer bearing comprising,a plurality of flexures unidirectionally aligned in parallel and aligned orthogonal to the top and bottom plates, the flexures extending vertically between the top plate and the bottom plate supporting the loading force, the flexures being thin for elastic bending back and forth in alternating unidirectional motion parallel to the top and bottom plates,top surface means for connecting together the plurality of flexures and for buttressing the top plate,bottom surface means for connecting together the plurality of flexures and for buttressing the bottom plate, andan aperture extending between the top surface means and bottom surface means for receiving the fastening means, the aperture being larger than the fastening means for providing space around the fastening means for enabling the fastening means to move relative to at least one of the top and bottom plates as the flexures bend back and forth as the top plate alternately and unidirectionally moves back and forth relative to the bottom plate.
