从平行四边形机构出发,综合得到了平面八杆机构联轴器。新的联轴器在确保输入、轴出轴之间的转速恒定相等的情况下,两轴之间的距离可在运转时作较大范围的调节。分析表明,其主要构件的惯性力能自身平衡,因而能适应高速场合,通过对机构的传动角分析得出结论,该联轴器具有较好的传动性能。最后,设计制造该联轴器的实物模型。 Starting from the parallelogram mechanism, a planar eight-bar mechanism coupling is obtained synthetically. The new coupling ensures that the input and output shaft at the same speed between the same circumstances, the distance between the two axes can be a wide range of adjustments during operation. The analysis shows that the inertia force of its main components can balance itself, so it can adapt to high speed applications. Through the analysis of the transmission angle of the mechanism, it is concluded that the coupling has better transmission performance. Finally, the physical model of the coupling is designed and manufactured.
