  • FIG. 8 shows schematically a layout of flows of the cooling medium for an inner roller cooling with a separate inflow for each cross-beam 30 .
  • the cooling media is fed in a corresponding conduit element in the cross-beam 30 via a distributor 400 and an associate medium connector 40 .
  • the cooling medium passed through the rollers 10 it is picked up again by a distributor 420 provided on the opposite side and is removed. The process correspondingly is carried out for a row of separate roller devices.
  • FIG. 9 shows an example of cooling of the roller bearing 20 in particular the middle bearing 20 , analogous so that of FIG. 8 .
  • the cooling medium against is fed in respective cross-beams 30 via a distributor 410 and then is transported by the conduit element provided in the cross-beam 30 to the middle bearing 20 and then, by the conduit element to the outlet distributor 420 .
  • FIG. 10 shows schematically distribution of the cooling medium for the secondary cooling.
  • the layout corresponds essentially to that shown in FIGS. 8 and 9 , namely, the cooling medium for the secondary cooling is fed to the cross beams 30 via the distributor 410 and then to the nozzles 50 of the secondary cooling.
  • FIG. 11 shows a variant of the secondary cooling, here, the cross-beams 30 are so arranged that they contact each other, and have conduit elements with medium connectors 42 corresponding to medium connectors 42 shown in FIG. 5 .
  • the header 410 ′ inside the cross-beams 30 is formed.
  • Separate conduit elements for distributing the secondary cooling medium correspondingly branch from the header 410 ′.
  • the secondary cooling medium takes place over the entire width of the cross-beam.
  • FIG. 12 shows a modified embodiment of FIG. 11 in which there is provided a first header 410 ′ and a second header 410 ′′ for the secondary cooling, and wherein the first header 410 ′ supplies the central nozzle 50 ′ with the cooling medium, and the second header 410 ′′ supplies the outer nozzles 50 with the cooling medium.
  • the distribution of the second cooling medium can be purposefully controlled.
