Device for mounting a speed-increasing gear for driving a centrifugal compressor

摘要

A speed-increasing gear 3 is interposed between an electric motor or a turbine with a shaft 10 and a compressor wheel mounted on the front end of a shaft 11. The gear comprises a wheel 14 and a pinion 58. The invention particularly relates to adjusting the axial play between the thrust bearings 18, 60 on either side of a collar 22 at the end of the shaft 11 carrying the compressor wheel and the lubricating system 16 for the pinion 58 on the shaft 11 carrying the compressor wheel. <IMAGE>
