摘要
齿轮齿条机构具有传动精密,往复运动易于实现;导杆机构尺寸设计相对容易,输出位移的设计范围大、传动角在输入输出端均为90°,传动效率高。当满足一定复合函数的数学条件时机构在极限位置可达到四阶停歇,为此设计了一种可以实现四阶停歇的九杆机构,使之兼具上述两种机构的优点,并且给出了设计原理及公式。
Gear rack mechanism is featured with precision transmission and easy achievement of reciprocating motion;the guide-bar mechanism has the characteristics that dimension design is relatively easy,the design scope of output displacement is wide,the transmission angles on both the input and output end positions are 90°,and the transmission efficiency is high.When given mathematic conditions of composite function are satisfied,the mechanism can reach four-ordered intermittence at limit position.Therefore,a kind of nine-bar mechanism that can carry out four-ordered intermittence was designed,of the rocker,making it have the advantages of both mechanisms,and giving its design principle and formula.
