Abstract:
An apparatus comprising;a gearbox housing; a first gear having a first axis of rotation about a first shaft; a second gear having a first end, a second end and a second axis of rotation about a second shaft, the first and second gears being rotatably mounted in the gearbox housing so that the first and second gears mesh with each other such that the first axis of the first gear is substantially perpendicular to the second axis of the second gear; and a gear isolator assembly disposed at at least one of said first end and said second end of said second gear said gear isolator including: an elastomeric member; a first washer having an annular planar section between a first washer inner flared edge and a first washer outer flared edge, the first washer disposed at a first axial end of said elastomeric member, a first width measured radially from the first washer inner flared edge to the first washer outer flared edge; a second washer having an annular planar section between a second washer inner flared edge and a second washer outer flared edge, the second washer disposed at a second axial end of said elastomeric member, a second width measured radially from the second washer inner flared edge to the second washer outer flared edge; wherein all radially measured outermost cross-sectional widths of the elastomeric member, from the first axial end to the second axial end, are less than the first width and less than the second width.
