本発明は、特許請求の範囲第１項の上位概念に記載の羽
根車に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an impeller according to the preamble of claim 1.
高速回転羽根車を軸、例えばターボ機械の羽根車の軸に
固定することはいるいるな問題を伴う。Fixing a high speed rotating impeller to a shaft, for example the shaft of a turbomachine impeller, is fraught with considerable problems.
２その際、次の点に注意しなければならない。2 In doing so, the following points must be noted.
即ち、なめらかな回転を保証するために羽根車を軸に対

て大きくなる。冒頭に述べた種の羽根車はスイス特許第
１０５７７４号により知られている。That is, in order to ensure smooth rotation, the impeller is installed at the same distance as D with respect to the shaft, by transmitting the rotational moment from the shaft to the impeller or from the impeller to the shaft, and by supporting the directional force. be. Expansion of the impeller caused by centrifugal forces, especially in the boss area, makes fixing the impeller difficult. In many cases, the impeller is heated more strongly than the shaft, so that the expansion of the impeller or the boss of the impeller is much greater than that of the shaft. An impeller of the type mentioned at the outset is known from Swiss Patent No. 105,774.
この場合、羽根担持体がボスとは無関係に膨張して危険

スから張出している。本発明の課題は、運転温度の影響
下で羽根車の熱が固定部に伝わらないように、冒頭に述
べた種の羽根車を提供することである。In this case, the vane carrier overhangs the hub in order to be able to expand independently of the hub and avoid dangerous stresses. The object of the invention is to provide an impeller of the type mentioned at the outset, such that, under the influence of the operating temperature, the heat of the impeller is not transferred to the fixed part.
この課題は、固定部と羽線担持体との間に断熱部によっ
て被われた冷却通路が設けられていることによって解決
される。This object is solved in that a cooling channel is provided between the fixing part and the wire carrier, which is covered by a heat-insulating part.
これによって、羽板担持体から固定部へ熱が伝わらない
ので固定部が膨張してプレスばめ部が弛くなることがな
い。図には本発明の実施例が略示されている。As a result, heat is not transferred from the wing plate carrier to the fixed part, so that the fixed part does not expand and the press-fit part becomes loose. The figure schematically shows an embodiment of the invention.
１で示した軸は鞠方向ストッパー２と、車由方向ガイド
部３と、プレスばめ部として形成された軸帯４を備えて
いる。The shaft designated by 1 is provided with a stopper 2 in the raceway direction, a guide part 3 in the vehicle direction, and a shaft band 4 formed as a press fit part.

る。The blade carrier 5 includes blades 6, a heat insulating part 7 formed to be easily deformable, and a post-shaped fixing part 8. The blade carrier 5 is mounted on the shaft 1 by connecting the boss-like fixing part 8 to the shaft band 4, for example by a shrink fit, in a relatively non-rotatable manner. According to the invention, a cooling channel 11 is provided between the press-fit part of the boss-shaped fixing part 8 and the paper carrier.

。A cooling medium line 10 is provided in the shaft 1 and flows into a cooling channel 11 which is open toward the shaft. Coolant pipe line 10
is in communication with a cooling medium supply unit (not shown). Since cooling air, cooling gas or cooling liquid can be supplied to the cooling channel 11 from a cooling medium line, additional cooling of the boss-shaped fixing part 8 is achieved. When the blade carrier 5 is heated, heat is not transferred to the boss-like fixing part 8 due to the action of the cooling passage 11 and the heat insulating part 7, so that the fixing part does not expand. It is therefore avoided that the fixing part 8 expands due to the action of the far-D force or due to thermal expansion of the vane carrier 5 and that the press fit on the ball becomes wet. The simplified illustrations in the drawings illustrate embodiments of the invention.
