Abstract:
A gear train assembly for an engine, comprising:(a) a first scissor gear rotatably coupled to the engine, said first scissor gear having a first rotational center;(b) a second scissor gear rotatably coupled to the engine, said second scissor gear having a second rotational center; and(c) an adjustable idler gear mechanism rotatably coupled to the engine, said mechanism including an idler gear forming a first mesh with said first scissor gear and a second mesh with said second scissor gear, said idler gear having a third rotational center, said mechanism including a guide defining a linear pathway for slidable adjustment of said third rotational center therealong, said pathway having a predetermined spatial relationship with said first rotational center to keep backlash between said first scissor gear and said idler gear at a predetermined minimum for a range of positions of said third rotational center along said pathway, said range of positions simultaneously providing a substantially greater range of backlash adjustment between said idler gear and said second scissor gear.
