Hy-Vo齿形链, 导板变异, 连结牢固度, 装配间隙, 有限元分析

Based on the assembly of a new type Hy-Vo silent chain and force analysis, a concept that the assembly clearance of chain can be compensated by reasonable shape design and the guide plate parameters was introduced. Elongation variables of the guide plates with different shapes in elongating procedure were analyzed and researched, and a new design method of butterfly-shape guide plate was proposed. By experiments the conclusion that butterfly-shape guide plate can compensate assembly clearance with smaller tension of chain is obtained. During that process, the pin and working plates can fully contact and bear the load together so that the bearing situation of the new Hy-Vo silent chain is also changed. The method is proved to be reasonable, from which important evidence for guide plate design can be acquired.
