The ring gear assembly includes an output ring gear having a circular inner periphery and is sandwiched between two earth ring gears each having a circular inner periphery. The flex spline has a first number of radially outwardly extending teeth around its outer periphery; and wherein each earth ring gear has the first number of radially inwardly extending teeth to engage with the teeth of the flex spline; and wherein the output ring gear has a second number of radially inwardly extending teeth, wherein the second number is greater than the first number.
