Turbocompressor

Abstract

A turbocompressor with an impeller rotatable about an axis of rotation for conveying a fluid, a diffuser downstream of the impeller in terms of flow, and a clamping ring for fixing a thrust bearing axially mounting the impeller in a bearing receptacle. The diffuser and the clamping ring are formed integrally and in a single piece with each other as a unit.

1 . A turbocompressor comprising:
 an impeller rotatable about an axis of rotation for conveying a fluid,   a diffuser downstream of the impeller relative to a flow of the fluid,   a clamping ring for fixing a thrust bearing to axially mount the impeller in a bearing receptacle, and   an inner housing for receiving a mount formed by the thrust bearing and/or a radial bearing, the inner housing providing the bearing receptacle,   wherein the diffuser and the clamping ring are formed integrally and in a single piece with each other as a unit,   wherein the unit consisting of the diffuser and the clamping ring forms an end-face housing cover of the inner housing,   wherein the thrust bearing is an aerodynamic thrust bearing with at least one thrust bearing washer, and wherein the unit consisting of the diffuser and the clamping ring forms a clamping section protruding in the axial direction for abutting one of the thrust bearing washers, the clamping section having an annular projection extending peripherally in the circumferential direction.   
     
     
         2 . The turbocompressor according to  claim 1 ,
 wherein the inner housing has a pot as a bearing receptacle for receiving the mount, and   the housing cover formed by the unit consisting of the diffuser and the clamping ring is connectable to the pot by at least one fastening element, and the mount is fixable in the pot by an axial clamping force generatable across the housing cover.   
     
     
         3 . The turbocompressor according to  claim 1 ,
 wherein the inner housing is also formed to receive an electric motor driving the impeller and forms cooling elements for cooling the electric motor,   wherein the unit consisting of the diffuser and the clamping ring is configured to direct the fluid conveyed by the impeller into and/or onto the cooling elements of the inner housing.   
     
     
         4 . The turbocompressor according to  claim 1 ,
 wherein the annular projection is perforated by channels running in the radial direction for decoupling the flow.   
     
     
         5 . The turbocompressor according to  claim 1 ,
 wherein the unit consisting of the diffuser and the clamping ring has a plurality of guide elements and/or cooling elements for cooling and pressure conversion of the fluid conveyed by the impeller.   
     
     
         6 . The turbocompressor according to  claim 1 ,
 wherein the unit consisting of the diffuser and the clamping ring has at least one aligning element for concentric alignment with respect to the axis of rotation and/or for concentric alignment of the thrust bearing with respect to the axis of rotation and/or for concentric alignment of an inflow nozzle arranged on an inflow side of the impeller with respect to the axis of rotation.   
     
     
         7 . The turbocompressor according to  claim 1 ,
 wherein the turbocompressor is a radial compressor or an axial compressor or a diagonal compressor.
