一、参数间的基本关系 设计曲柄滑块机构需要决定的机构参数有:曲柄长度r、连杆长度l,曲柄转动中心相对于滑块移动导路中心的偏置量e、滑块初始位置x、滑块工作行程H、机构的行程速比系数K和机构工作时的最大压力角αmax等七项。若为对心曲柄滑块机构,则e=0,k= First, the basic relationship between parameters Design crank slider body mechanism parameters to be determined are: crank length r, connecting rod length l, crank center of rotation relative to the slider moving the center of the offset e, the slider initial position x , Slider work schedule H, the agency’s travel speed ratio coefficient K and the maximum working pressure angle αmax and other seven. If the heart crank slider mechanism, then e = 0, k =
