Information on bevel gears and their applications is comprehensive where external bevel gears are concerned but proves to be more scarce when related to internal bevel gears, despite the fact that there are isolated practical examples of the use of such gears that have demonstrated their effectiveness in demanding transmission situations.
In what follows a unique family of transmissions is examined, based solely on a particular layout of internal and external bevel gear combinations, that aims to demonstrate the wide ranging, largely unexploited, potential of transmission systems of this kind.
