ABSTRACT:
A planetary gear assembly comprising a primary array (2) of co-axial planetary gear sets and a secondary array (3) of co-axial planetary gear sets, planetary gear set being provided with an associated gear engagement means (21), the arrangement being such that in use each planetary gear set and the associated gear engagement means are arranged for relative translational movement which is substantially parallel to the axis of the respective array of planetary gears and a rotational input drives a selected primary gear set which is engaged with the associated gear engagement means, the rotational output of the engaged primary gear set (2) being transmitted through the associated gear engagement means (21) to gear engagement means which is engaged with the associated selected secondary gear set (3), the output from the selected secondary gear set being transmitted to rotational output means (18, 49).
