摘　　要：双曲柄机构在工程实际中应用非常广泛,主要是利用主动曲柄等速转动,推动从动曲柄变速转动而产生的运动不均衡性。根据双曲柄机构从动曲柄单向转动的运动特性,在双曲柄机构运动特性研究的基础上,定义双曲柄机构行程速比系数K,给出行程速比系数K的参数方程及其定义域,通过几何分析推导,重点讨论K值为定值,设计、制造及安装对K值的影响最小时从动曲柄所在位置的时候,双曲柄机构的设计方法,提出一种综合优化双曲柄机构的新思路。Double‐crank mechanism has a vast practical engineering application , w hich involves the movement unevenness created by the driven crank’ s non‐uniform rotary impelled by driving crank’ s uniform rotary . According to the one‐way rotary property of the driven crank in the double‐crank mechanism ,the stoke speed ratio K of the double‐crank mechanism is defined ,and the parameter equation and its domain of definition are provided based on studies of the movement characteristics of the double‐crank mechanism .It focuses on the designing method to be applied w hen K value is a fixed value and the position of the driven crank is determined with the K value having a minimum influence from the designing ,manufacturing and installing process .And it presents a new idea of an integrated optimized double‐crank mechanism .
