- compressor stages can be connected in series.
- turbocompressors As types of turbocompressors, a distinction is made between radial and axial compressors.
- the fluid to be compressed for example a process gas
- the fluid to be compressed flows in a direction parallel to Axle (axial direction) through the compressor.
- the gas flows axially into the impeller of
- Such a transmission compressor a transmission compressor from Siemens called STC-GC, used for air separation, is out
- the single pinion shafts are in mesh geometry and pinion shaft center position (center ⁇ point or rotation axis of a pinion shaft) with the bull gear to and coupled to each other.
- pinion shaft center position center ⁇ point or rotation axis of a pinion shaft
- a significantly determining and limiting size is the available and / or realizable space, especially the outside of the housing - as

- D. h. Such a multi-toothed large gear has (axially) offset Verzah ⁇ calculations, which mesh with different pinion shafts.
- the assembly of the fourth pinion shaft is only by lateral insertion (plugging) possible (Steckritzelwelle).
- the pinion shaft center positions can be selected almost freely taking into account the volute casing of the first parting line. But here, too, the realization involves a considerable amount of extra work (assembly parts, assembly process).
- Housing element and a connected to the first housing member via ei ⁇ ne parting joint, second housing member and the at least two pinion shafts in the parting line can be accommodated.
- DE 10 2011 003 525 AI then further provides that the
- Parting line has a trained as a vertical step part of the joint gap, which forms two different horizontal levels in the parting line, wherein the at least two pinion shafts in the parting line on both sides of the parting joint jump in the two different horizontal levels can be accommodated.
- the partial joint jump or the vertical step in the transmission compressor housing from DE 10 2011 003 525 AI thereby sealed using a cylindrically shaped, screwed on the partial joint jump sealing lens.
- the invention has for its object to provide a housing for a transmission, in particular for a transmission of a gear ⁇ beverêtrs, which improves the disadvantages of the prior art, in particular space-optimized, a ⁇ fold and inexpensive to implement and also simple and inexpensive to assemble and allows different translation ratios of the transmission at low manufacturing ⁇ and cost.
