The invention relates to a Wolfrom gear comprising a driven sun gear (4) provided with two internal toothed ring gears (22, 24) and planet gears (8) which are mounted in an axially displaceable manner in a planet carrier (18) and which comprise two conically toothed geared areas (6, 10). According to the invention, the geared area of a ring gear (24) is nearly cylindrical and the geared area of the other ring gear (22) is conical. In addition, the planet gear axes (12) are inclined at an angle of inclination ( alpha ) of the axis. An axially effective planet carrier bearing (26) is provided between the planet carrier (18) and the ring gear (22), and the axial position of the planet carrier (18) can be adjusted with regard to the ring gear (22) in order to simultaneously adjust the backlash of the teeth of both ring gears (22, 24). |
