Summary:1292858 Coupling parts of a gas turbine rotor KONGSBERG VAPENFABRIKK AS 24 Nov 1969 [25 Nov 1968] 57454/69 Heading F2U Two sections 1, 2 of a gas turbine rotor are clamped axially by a projection 8 on the hub 3 of one section passing through a bore 10 in the hub 4 of the other section to which it applies a clamping force via a compression sleeve 13. The sleeve 13 may be clamped between a shoulder 12 and a washer 15 under the head of a bolt 14 screwed into a tension sleeve 9 screwed on to the projection 8. The sections 1, 2 may be centred by teeth 7. There may be two compression sleeves one inside the other and separated by a tension sleeve, the sleeves having clearances between them smaller than that between the outer sleeve 13 and the bore 10.
