Abstract

The invention relates to a wind-power unit having a wind turbine with vertical shaft, a supporting pole, a generator and a vertical shaft (4). The shaft (4) is with its upper end connected to the turbine and with its lower end to the generator. According to the invention, between the upper and lower ends, the shaft (4) is supported by at least two axially separated supporting devices (13). Each supporting device (13) has at least three supporting components (15) that abut against the shaft (4) and that are connected to the supporting pole.
