Abstract:
A gear train assembly for an engine, comprising:(a) a first scissor gear rotatably coupled to the engine, said first scissor gear including a first rotational center;(b) a second scissor gear rotatably coupled to the engine, said second scissor gear including a second rotational center; and(c) an adjustable idler gear mechanism 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 including a third rotational center, said mechanism further including a first pin fixed relative to said third rotational center and a guide surface slidably engaged by said pin to define a pathway to adjustably position said third rotational center, said pathway defining 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 further providing a range of backlash adjustment between said idler gear and said second scissor gear.
