Abstract

Disclosed is a gearbox having a central shaft (1), which is rotatably mounted relative to a stationary frame element (2) by means of at least one central shaft bearing (3), a first sun gear (4a) arranged concentrically around the central shaft (1) and fixedly secured to the frame element (2), a power transmission means (5) that is fixed in relation to the central shaft (1), and at least one first gearbox assembly (6a) rotating relative to the frame element (2) and comprising: a support plate (7), the first section (7a) of which is non-rotatably connected to the central shaft (1) and on the second section (7b) of which a planetary gear (8) is mounted by means of a planetary gear bearing (9), wherein the planetary gear (8) meshes with the first sun gear (4a) and a crank arm (10) engages rigidly with the planetary gear (8); and a driving crank (11), on which the crank arm (10) is hingedly mounted by means of a driving crank-crank arm bearing (12) and which is supported relative to the support plate (7) by means of a kinematic coupling means (13). The aim of the invention was to provide a gearbox which has the most compact dimensions possible in the axial direction of the central shaft…
