if a simple gear train has three gears, such that the input gear "g" meshes with an intermediate gear "g" which in turn meshes with the output gear "g", then the pitch circle of the intermediate gear rolls without slipping on both the pitch circles of the input and output gears. this yields the two relations









































the speed ratio of this gear train is obtained by multiplying these two equations to obtain
