摘要

The compressor has a main rotor (1) and an auxiliary rotor including shaft projections (2) arranged at a axial slide bearing (25) that consists of a main bearing (26) and an auxiliary bearing (27), which have tilting segment carriers (12) equipped with tilting segments and joined at both sides of an axial-bearing slide ring (13). An axial force compensation device is arranged on a shaft end of the main rotor. A bearing play ring is arranged in periphery of the axial bearing. Axial extension of the axial bearing is joined axially to support rings that hold the axial-bearing slide ring.
