Firstly

basic operating principle of Pearl Rope Chain Actuating Machanism to actualize constant proportion driving between capstan shaft and driven shaft that are distance and interspace in illuminated.Moreover

mechanism design including location relation between drive and driven shaft and guide wheel shaft

and between drive and driven wheel central plane and guide wheel external cylinder plane are analyzed.At the same time

refined calculation of pearl strip length was studied profoundly.Finally

a conclusion is successly reached that pearl rope chain actuating machanism is a sort of late-model driving form.
