Title: GEARBOX OF A WIND TURBINE
Abstract:
The present invention relates to a wind turbine gearbox having at least two gearing stages, comprising a first gearing stage (1) and a second gearing stage (2) coupled thereto, wherein the coupling of the two adjacent gearing stages (1, 2) is formed by means of a plug-in toothing (3) which comprises an at least partially internally-toothed hollow shaft (4) which has an at least partially correspondingly externally-toothed connecting shaft (5), wherein the insertion depth of the connecting shaft (5) is delimited by a stop shoulder (12) which extends radially inwards and is formed on the hollow shaft (4). A stop ring (14) attached to the end face of the hollow shaft (4) is provided on the axial end of the plug-in toothing (3), said axial end lying opposite the stop shoulder (12), and the stop ring is surrounded by a slide ring (16) which is floatingly mounted and secured against rotation on a stationary housing (9) or a planetary carrier.
