摘要： ：在曲柄连杆机构设计中，为了实现曲柄到曲轴中心距离适时可调，对曲轴
结构进行了创新设计。通过凸轮槽与圆盘在同步转动产生相对转动，实现了平面连杆机构在
连续运转情况下实现曲轴偏心距调整；同时采用特殊中间凸轮结构实现了可以带动有多个相
位差曲拐同步转动，使整台机构在运动过程中具有适时调节运动参数的能力。通过ADAMS
仿真分析表明，该结构完全能满足系统无级调速的需要；同时曲柄上曲拐位移与原动件蜗杆
的转动角度基本呈线性关系，为产品调速部分的刻度分度打下了基础。

Abstract: In the design of crank connecting rod mechanism, in order to timingly adjust
the distance from the crank to the center of the crankshaft, an innovative design of the
crankshaft structure is given. Through the CAM slot with relative rotation disc in synchronous
rotation, the planar linkage mechanism in the circumstance achieves the adjustment of the
crank shaft eccentricity, and can bring crank which was realized using the middle CAM phase
synchronous rotation. ADAMS simulation analysis shows that the structure can meet the
needs of the stepless speed regulation system, the crank displacement and the original
dynamic basic linear relation.
