【摘要】：双节距齿形输送链链板结构是内外复合啮合标准齿形链链板的变异结构,在齿形链啮合原理中,内外复合啮合齿形链的链板结构参数伸出量没有明确的数值关系,导致设计的链条无法最优地实现内外复合啮合机制的功能。基于Solid Works/motion软件创建了双节距齿形输送链链板的参数化模型及与特定链轮齿数相对应的简化的运动分析模型,以伸出量的高度Y与数值δ为变量,以实现内外复合啮合过程与最小啮合冲击力为目标进行仿真分析。结果表明,链轮齿数一定时,伸出量是影响链条实现内外复合啮合过程的重要参数;综合比较,当链轮齿数为38齿,伸出量取值高度Y为0.25P_S,数值δ为0.013P_S时,能够实现双节距齿形输送链与渐开线链轮的内外复合啮合过程,且啮合力最小,结构最优。
[Abstract]:The double pitch tooth transmission chain chain structure is a variant structure of the internal and external composite meshing standard tooth chain chain plate. In the meshing principle of the tooth chain, there is no definite numerical relation between the chain plate structure parameters of the inner and outer composite tooth chain and the chain plate structure parameter. The designed chain can not realize the function of internal and external composite meshing mechanism optimally. Based on Solid Works/motion software, the parametric model of double pitch tooth conveying chain plate and the simplified kinematic analysis model corresponding to the specific number of sprocket teeth are established. Taking the height of extension Y and the value 未 as variables and taking the process of internal and external composite meshing and the minimum meshing impact as the target, the simulation results show that the sprocket teeth number is constant. When the number of sprocket teeth is 38 teeth, the protruding height Y is 0.25 PSP, and the value 未 is 0.013P_S. It can realize the internal and external composite meshing process of double pitch tooth conveying chain and involute sprocket, and the meshing force is minimum and the structure is optimal.
