Abstract: A spur gear arrangement includes a spur gear, and two flange bushings configured to rotatably support the spur gear on a shaft, with each flange bushing including a flange. A lubricating film is provided between an inner side of the spur gear and each of the flange bushings. Two supporting bodies are arranged on the shaft, with the flange bushings being respectively arranged with their flange on the supporting bodies for axially bracing the spur gear.

Abstract: A planetary gear train for a wind power plant includes a planetary stage rotating in a gear train housing, a spur gear stage downstream of the planetary stage, a sun wheel shaft which is non-rotatably connected to a sun wheel of the planetary gear stage, and a hollow shaft which is coaxially surrounded by a spur gear of the spur gear stage and is non-rotatably connected to the spur gear. The sun wheel shaft and the hollow shaft are non-rotatably connected to each other by a toothed coupling, with an outer toothing of the sun wheel shaft meshing with an inner toothing of the hollow shaft. The planetary gear train includes oil-guide ducts which produce a connection between an oil inlet connected to the gear train housing, on the one hand, and the toothed coupling and the axial contact surface, on the other hand.
