摘　　要：本文分析了平行对称传动的曲柄滑块机构双侧运动学参数存在误差时所引起的不对称传动特性,进而提出一种衡量这类机构传动不对称性的指标。研究了曲柄长度、曲柄位置角和连杆长度存在误差时不对称度的变化规律,并从概率的角度,分析了运动学参数的分布对机构不对称度分布的影响。This paper makes an analysis in the asymmetry transmission character caused by the existing error of kinematic parameter for the double sides of crank-slider mechanism of parallel and symmetric transmission. Then proceed to propose a kind of index for measuring the transmissive asymmetry of this kind of mechanism. The variational rule of asymmetry is being studied while error is existing in crank length, in positional angle of crank and in length of connecting rod. And from the probability point of view analysis is made on the effect of the distribution of mechanisms asymmetry caused by the distribution of kinematic parameter.
