Abstract
Official abstract text for this publication.
A geared compressor rotor for cold gas applications is provided. The geared compressor rotor includes a pinion shaft having a gear tooth segment having gear teeth. The rotor further includes at least one impeller wheel having an impeller wheel hub and a sealing segment arranged between the gear tooth segment and the impeller wheel hub that bears a seal. The impeller wheel hub and the sealing segment form a common, continuously coherent region composed of a first material. The toothing segment is formed from a second material. The first material is tougher at subzero temperatures than the second material.
First claim
Opening claim text (preview).
The invention claimed is: 1. A geared compressor rotor for cold gas applications, comprising: a pinion shaft comprising a toothing segment having a toothing, at least one impeller wheel comprising an impeller wheel hub, a sealing segment arranged between the toothing segment and the impeller wheel hub and bearing a gasket, wherein the impeller wheel hub and the sealing segment form a common, continuously coherent region composed of a first material, wherein the toothing segment is formed from a second material, and wherein the first material is tougher at subzero temperatures than the second material, wherein a pair of separate and different material regions is defined by the first material and the second material, wherein a rotationally fixed connection is arranged between the pair of separate and different material regions by way of a Hirth coupling effective to transmit an axial force or torque between the pair of separate and different material regions. 2. The geared compressor rotor as claimed in claim 1 , wherein the impeller wheel is mounted in a cantilevered fashion. 3. The geared compressor rotor as claimed claim 1 , wherein the second material is harder than the first material. 4. The geared compressor rotor as claimed in claim 1 , wherein a rotor bearing is arranged in the region of the second material. 5. The geared compressor rotor as claimed in claim 1 , wherein a rotor bearing is arranged between the sealing segment and the toothing segment. 6. The geared compressor rotor as claimed in claim 1 , wherein the pair of separate and different material regions is arranged between the sealing segment and a rotor bearing.
