1.差动式锥齿分度盘的结构(附图) 固定在主轴6上的齿盘1由内齿圈一组成,齿盘2、3由内齿圈和外齿圈组成,齿盘4由外齿圈组成。在啮合副A、B、C处,内外齿因具有相同的齿数及锥度(包括齿高方向和齿侧方向),所以在A、B、C处理论上形成无侧隙啮合。齿盘从一端固接波纹管5,波纹管可以 1. Structure of differential beveling indexing plate (drawing) The chainring 1 fixed on the main shaft 6 is composed of an inner ring gear, the chainring 2,3 consists of an inner ring gear and an outer ring gear, and the chainring 4 Composed of external gear. At mating pairs A, B and C, the internal and external teeth have the same number of teeth and taper (including tooth height direction and flank direction), so there is no backlash in A, B, C theory. Gear teeth from one end of the fixed bellows 5, bellows can be
