与外接不完全齿轮机构相比,内接不完全齿轮机构由于其结构紧凑,运动平稳,动作时间设计范围广和齿面承载能力强而得到应用。下面结合这些特点讨论内接不完全齿轮机构的运动设计。一、啮合特点,K值和外齿轮h(?)值的确定如图1所示,设相啮合的两个齿轮都是标准齿轮而没有变位。从动内齿轮2为完全齿轮,齿数Z_2,分度圆半径r_2,顶圆半径r_(a2),齿顶高
Compared with the incomplete gear mechanism, the internal incomplete gear mechanism is applied due to its compact structure, stable motion, wide range of design time and high bearing capacity. The following combination of these characteristics to discuss the internal incomplete gear mechanism movement design. First, the meshing characteristics, K value and external gear h (?) Determination of value As shown in Figure 1, set the two gears engaged are standard gear without displacement. The driven internal gear 2 is a complete gear, the number of teeth Z_2, the radius of the indexing circle r_2, the radius of the top circle r_ (a2), the tooth top height
