Abstract
Nach der Erfindung wird ein Rotationsverdichter, wie ein Schraubenverdichter (1), angegeben, bei dem eine zuverläs sige Zentrierung der Rotoren (5, 6), insbesondere der Lage rungen (13, 14) der Wellenenden (10, 11) der Rotoren (5, 6) am druckseitigen Ende (8) des Schraubenverdichters (1) ohne großen fertigungs- und montagetechnischen Aufwand da durch erreicht wird, daß der Gehäusemantel (2) in axialer Rich tung so verlängert wird, daß er sich wenigstens über die Wel lenenden (10, 11) der Rotoren (5, 6) erstreckt und einen Auf nahmeraum (12) für die Lagerungen (13, 14) der Wellenenden (10, 11) bildet. Zur Lagerung der Wellenenden (10, 11) werden Lagerhülsen (15, 16) in dem Aufnahmeraum (12) angeordnet, die sich relativ zueinander und in der Öffnung (18) des Aufnah meraums (12) für die Lagerungen (13, 14) selbsttätig zentrie ren. Zur axialen Lagefixierung der Lagerhülsen (15, 16) wird ein Abschlußdeckel (20) am Gehäusemantel (2) befestigt. Die Öff nung (18) für den Aufnahmeraum (12) der Lagerungen (13, 14) ist hierbei eine unmittelbare Verlängerung der Öffnung(en) (3) des Arbeitsraums (4), in dem die Schraubenrotoren (5, 6) an geordnet sind. According to the invention, a rotary compressor, such as a Screw compressor (1), indicated, in which a reliable sige centering of the rotors (5, 6), in particular the location stanchions (13, 14) of the shaft ends (10, 11) of the rotors (5, 6) on pressure-side end (8) of the screw compressor (1) without great manufacturing and assembly costs is achieved by that the housing jacket (2) in the axial direction tion is extended so that it at least over the world lenenden (10, 11) of the rotors (5, 6) extends and an up receiving space (12) for the bearings (13, 14) of the shaft ends (10, 11) forms. To support the shaft ends (10, 11) Bearing sleeves (15, 16) arranged in the receiving space (12), which are relative to each other and in the opening (18) of the receptacle meraums (12) for the bearings (13, 14) automatically center ren. For the axial position fixing of the bearing sleeves (15, 16) is a End cover (20) attached to the housing jacket (2). The public tion (18) for the receiving space (12) of the bearings (13, 14) is an immediate extension of the opening (s) (3) the work area (4) in which the screw rotors (5, 6) are ordered.
