A device for introducing a high-temperature fluid into a rotating body, comprising a pipe (2) through which said fluid passes, and which is solidly connected to said rotating body. The pipe is rotatably coupled to a support (6) by means of bearings (7). In order to reduce the heat stress on the bearings (7) a cooling fluid is fed to an annular cooling conduit (11) which is interpositioned between the bearings (7) and the pipe (2) and is solid in rotation with the pipe (2). The cooling conduit (11) exhibits an inlet (12) and an outlet (13) for the cooling fluid. The device is especially useful in the paper industry for introducing a heat transferring fluid into a drying cylinder or calender. |
