It is important for the strength design to clarify the impact strength of roller chains because they are applied to the repeating impact load for chain drives. Firstly in this study, the relation between the repeating impact energy and the number of repetitions to impact failure. In the next step, the distribution of the failure sections is exmained. They are compared with the results of the repeating impact test of roller link and pin link. Further, the effects of the number of links on the repeating impact strength is investigated, and studied statistically. The obtained results are as follows : (1) The results of repeating impact test of roller chains indicate that the repeating impact strength reduced as the number of links are increased. (2) When roller chains are applied to higher repeating impact energy, they are a failured in pin link-plates and in the case of lower ones, they are a failured in roller link-plates. (3) The repeating impact life distribution could be estimated statistically by using the life distribution of single roller link and pin link.
