Abstract

A compressor includes a shaft assembly including a thrust disk disposed on a main shaft and a housing having a first portion and a second portion, the first and second portions adapted to receive the shaft assembly and enclose the shaft assembly therebetween, wherein the shaft assembly is rotatably disposed within the housing, and wherein at least one of the first portion and the second portion includes a shaft assembly retention feature for receiving the thrust disk to regulate a motion of the shaft assembly.

Description

technical field [0001] The present invention relates to fuel cell systems, and more particularly, the present invention is directed to a compressor for a fuel cell system and a method of manufacturing the compressor. Background technique [0002] One instance of fuel cell compressor technology is typically fitted with air bearings in order to create an oil-free air bearing for the fuel cell stack. Axial air bearings (thrust bearings) are located close to the compressor stage and require a stationary housing portion disposed adjacent the front side of the thrust bearing and between the rotating compressor wheel and the rotating thrust disk. [0003] Typically, all rotating parts of the compressor are positioned together on a common shaft assembly, which is balanced with high precision, prior to compressor assembly. Once the shaft assembly has been balanced, the shaft assembly must not be disassembled to maintain its balance. One problem is that the stationary front side of ...
