One of the important characteristics of the chain overrunning clutch is its higher carrying capacity than the conventional overrunning clutch. This paper analyzes various factors that affect the carrying capacity of the chain overrunning clutch. It points out that the contact stress is the most important factor that affects its carrying capacity and service life. The mechanical model of the overrunning chain clutch is analyzed and derived In order to calculate the contact stress of the chain overrunning clutch contact point and to consider the influence of the friction force, a corresponding calculation program is compiled according to the result, which is of certain reference value to the design and calculation of the chain overrunning clutch.
