ROTOR OF SCREW COMPRESSOR, AND ITS MANUFACTURING METHOD |
摘要 |
FIELD: machine building.SUBSTANCE: rotor 1 of screw compressor includes working part 2 and shaft 6. At least some part of shaft 6 is located in central or almost central longitudinal hole or channel 5 of working part 2 of rotor. Shaft 6 includes extending element 7. Working part 2 of rotor or at least some part thereof is retained on shaft 6 by means of straining elements 11 and 12, which are fixed along longitudinal axis of the shaft and connected to each other through the above extending element 7 that during installation of working part 2 of rotor on shaft 6 is pre-extended. After fixation of straining elements 11 and 12 and relief of tension load element 7 is retained in the state of preliminary longitudinal tension. Preliminary strain is performed by means of straining elements 11 and 12, which are separated from each other with working part 2 of rotor or with some part thereof.EFFECT: reduction of material consumption and providing rotor cooling.32 cl, 11 dwg |
