| 摘要 |
The invention relates to a geared compressor (GTC), comprising a gearing housing (GC), a drive shaft (DS), a plurality of radial fluid energy machines, at least a first radial fluid energy machine (CO1) having a first pinion shaft (PCO1) and a second radial fluid energy machine (CO2) having a second pinion shaft (PCO2), a gearing (GR) comprising a large gear (BW), wherein the large gear (BW) and the drive shaft (DS) have a common first axis of rotation (X1), wherein a set of external teeth (OTBW) of the large gear (BW) directly or indirectly drives the first pinion shaft (PCO1) and the second pinion shaft (PCO2). In order to reduce costs and space requirements, the drive shaft (DS) according to the invention is rigidly connected to a sun gear (SW) of a planetary gearing (EPG) and drives the large gear (BW) by means of planet gears (PW) of the planetary gearing (EPG), wherein the large gear (BW) is designed as a ring gear of the planetary gearing (EPG) and meshes with the planet gears (PW) by means of a set of internal teeth (ITBW) and is driven by the planet gears (PW). |
