摘要：
The method of planar four-bar mechanism movement precision analysis is proposed when the length errors and kinematical pair clearances are taken into account. The offset vector caused by the clearance of kinematical pair is analyzed and the position vector is used to describe the position of bodies. The structure for the two-hole swing deputy is studied. The magnitude and direction of rotary vice offset is seen as random variable. The calculating formula of two-hole effective lever length model is deduced. The output accuracy of four-bar mechanism with two-hole the clearance is analyzed.
