ROTOR AND COMPRESSOR EQUIPPED WITH SUCH ROTOR

摘要

FIELD: engines and pumps. ^ SUBSTANCE: rotor includes shaft 6 with axis A-A', in which in the direction of the above axis there is central inner cooling channel 8 with inlet 9 and outlet 10 for cooling agent. Channel 8 at least in its part is equipped with inward directed ribs 11. In channel 8 near inlet 9 there located are devices 24 providing tangential velocity component for cooling agent. Devices 24 include star-shaped insert-type element 25 with cone-shaped end directed from the above ribs 11 against cooling agent flow direction. ^ EFFECT: effective cooling of rotor. ^ 19 cl, 9 dwg
