Abstract (en)

[origin: EP0607999A2] In order to prevent, in a shaft cooling system, the gearing from being cooled in an unacceptable manner, the radial heat flow is reduced in the gearing region (7v) of the shaft, with respect to the heat flow in shaft regions to be cooled (7), for example by an insulating air chamber (19). <IMAGE>
