Embodiment Construction

[0027] figure 1 A schematic perspective view of the first subhousing C1 with the joint SP is shown, wherein the joint SP is represented by the sealing surface SF. The first sub-housing C1 is constituted as a lower housing part CL, wherein the upper housing part—in figure 2 Shown in - installed on the lower part of the housing CL. Housing upper CU in figure 2 is visible in section. The sealing surface SF of the joint SP is interrupted at various points by the shaft passing from the housing interior CI to the housing exterior AMB, since the axis of rotation of the respective shaft lies in the plane of the joint SP. The outwardly directed shafts are the shafts SH1 , SH4 and SH3 , which rotate about the axes X1 , X3 or X4 . The shafts SH4 and SH3 are formed as so-called pinion shafts and lead outwards from the housing interior CI on both shaft end sides. The first shaft SH1 , which rotates about the first axis X1 , is also referred to as the gear shaft and is guided outward...

Abstract

The invention relates to an integrally geared compressor (GV) comprising a casing (C), which can be separated at a separating joint (SP) into a first partial casing (C1) and a second partial casing (C2), wherein said casing encloses a casing interior (CI), a first shaft (SH1), which supports a first gearwheel (GW1) and is mounted along a first axis (X1) in at least one first bearing (B1), and a second shaft (SH2), which supports a second gearwheel (GW2) and is mounted along a second axis (X2) in at least one third bearing (B3). The invention proposes that at least the third bearing (B3) has a third bearing block (LB3), which supports the bearing (B3) fully and that the third bearing block (LB3) is arranged entirely within the casing interior (CI) and that the third bearing block (LB3) is detachably mounted only on the first partial casing (C1), so that the construction design means with respect to the axle distances for the drives of the individual compressor stages and for the drive of the integrally geared compressor on the transmission can be designed more flexibly without losing the advantage of simplified disassembly of the transmission casing.

Description

technical field [0001] The present invention relates to a gear type compressor, which comprises a housing, which can be decomposed into a first sub-housing and a second sub-housing in a joint portion, and the housing encloses the inner chamber of the housing; and also includes a second sub-housing. a shaft carrying a first gear and supported in at least one first bearing along a first axis; and a second shaft carrying a second gear and supported in at least one bearing along a second axis in at least one third bearing. Background technique [0002] In the sense of the present invention, a gear compressor is a multi-stage turbo compressor in which the individual stages are kinematically coupled relative to one another by means of a transmission and at a drive. In this case, the transmission is usually mounted in a housing and the individual compressors or compressor stages are flanged to the transmission housing. In this case, the transmission provides drive shaft ends prot...
