Title:
TURBOCOMPRESSOR ROTOR AND TURBOCOMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2012/010514
Kind Code:
A3
Abstract:
The invention relates to a turbocompressor rotor (TVR), comprising at least one shaft (SH) extending along an axis of rotation (AX), wherein said shaft (SH) comprises a plurality of axial regions: at least one radial bearing region (RBA1, RBA2) for mounting by means of a magnetic bearing, at least one shaft sealing region (SSA1, SSA2) for sealing a gap between the rotating shaft (SH) and a stationary part, at least one aerodynamic region (AERA) bearing blades or impellers (IMP) which are used for fluid compression. For better mounting, cost reduction, and reducing the expenditure on maintenance with the same or improved efficiency, according to the invention the shaft has an axial separation point (DP1, DP2) between two axial regions, namely the shaft sealing region (SSA1, SSA2) and the radial bearing region (RBA1, RBA2), wherein the separation point (DP1, DP2), the shaft sealing region (SSA1, SSA2) and the radial bearing region (RBA1, RBA2) are designed such that a shaft seal (SS1, SS2) and a radial bearing (RB1, RB2) can be removed from the shaft sealing region (SSA1, SSA2) or the radial bearing region (RBA1, RBA2) when the separation point (DP1, DP2) is separated from the shaft (SH).
