SPIRALVERDICHTER, INSBESONDERE ZUM EINSATZ BEI DER DRUCKLUFTERZEUGUNG FÜR SCHIENENFAHRZEUGE
摘要:
In a totally oil-free spiral compressor (1) with high suction volume flows and compression ratio, useful in particular to generate compressed air for rail vehicles, the spirals are arranged on one side only and measures are taken to compensate for the high axial forces that act on the spiral bearings. Compression chambers (35) arranged with an axial gap between the spirals (7, 9) of the spiral compressor (1) are fed by compression pockets (45) and support the nested spirals against each other. The compression chambers (35) are preferably arranged between a compression crown (15) joined to the driving spiral (7) and a ring wheel (37) of the forcibly driven second spiral (9), so that axial counterforces compensate for the axial forces that act upon the bearings (29, 33) of both spirals.
