摘　　要：针对双曲柄环板式针摆行星传动中的平行四杆机构,运用动力学原理分析了机构中杆长尺寸误差和运动副侧隙等随机变量对转臂轴承载荷的影响,并建立了力分析模型,为在设计双曲柄环板式针摆传动时,更好地计算各构件的强度、动力性能及机构可靠性等提供了一定的理论基础。Aimed at the parallel four-bar linkage in ring-plate-typed pin-cycloidal epicyclic drive and by utilizing the dynamics principle the influence on bearing load in rotary arm affected by the stochastic variables of dimensional error on bar-lengths of the mechanism and of side clearance of moving pairs etc. was analyzed. The force analysis model was established as well, thus provided certain theoretical basis for a better calculation on the strength, kinetic property of each component and reliability of mechanism while designing the double-crank ring-plate-typed pin-cycloidal drive.
