Definitions
- the invention relates to a multi-stage single-stage double gear driven turbo compressor, a so-called geared turbo compressor with the features of the preamble of Claim 1.
- a known turbo compressor of the generic type Art (DE-PS 9 74 418, DE-OS 21 15 331, Dubbel paperback for mechanical engineering 14. Edition, 1981, pages 920 - 921) has four compression stages on, whose impellers in pairs two pinion shafts arranged and via a central one Drive gear of a single-stage gear are driven.
- DE-OS 37 07 992 is a geared turbo compressor known, between the drive shaft and the one that carries the compressor impellers Pinion shaft arranged an intermediate gear is.
- This intermediate gear serves as a lock-up a large center distance between the Drive shaft and the pinion shaft so that at small Flywheels a low speed in one very high speed can be translated.
- the US-PS 23 13 205 shows a transmission for one Turbo compressor, the two arranged on a shaft Gear wheels of different diameters contains, via which the drive shaft with the compressor shaft connected is.
- DE 40 03 482 C2 and EP 0 440 902 B1 show a geared turbo compressor with a two-stage gearbox that has a double idler gear contains, with a smaller gear and a slightly larger gear together a wave shrunk and thereby one Unit connected, the smaller one Gear has the larger tooth module and engages with the main drive gear and the larger gear a much smaller one Has tooth module and the pinion shafts 3, 4 and 5 drives.
- the pinion shafts 1 and 2 are with and the main drive gear driven by this.
- the level of the achievable efficiency of a turbocompressor depends on whether the dimensionless "specific speed" ⁇ of each individual compressor stage can be kept in the optimal range despite strong changes in volume flow due to the compression from compressor stage to compressor stage.
- each one Compressor stage is according to the written relationship from the secondary Speed, the inlet volume flow and depending on the size Y, where Y from the gas data, the inlet temperature and especially from that pressure ratio the compressor stage becomes.
- Step pressure ratio only a little or can be constant, the inlet volume flow changes through the compression strong from level to level.
- the speed must increase from step Level or at the latest after two levels increase.
- Rising pressure ratios are inseparable from increasing flow velocities coupled When approaching take on the speed of sound the flow losses increase sharply and thus the efficiency, the step pressure ratios are therefore limited.
- Turbo compressor for high pressure conditions require a corresponding number of compressor stages.
- the intermediate gear requires a separate one Bearing (axial and radial), the bearing journal at about twice the drive speed (or more) circulate. Also add up at an input gear the input and output tooth forces and increase the bearing load. The generate relatively high peripheral speeds considerable additional mechanical losses. That engages with the main drive gear standing gear of the double idler gear has the same peripheral speed as that Main drive gear. The second with the smaller one Tooth module has a higher peripheral speed and like storage creates additional mechanical losses. The construction effort for the gearbox, including the Oil supply for the idler gear is considerable higher.
- the invention has for its object a Geared turbo compressor for high pressure ratios with optimal efficiencies or combination turbo compressors with strongly differing volume flows with optimal efficiencies build without the use of a double idler gear according to DE 40 03 482 C2 and EP 0 440 902 B1.
- the secondary ring gear By shrinking on a secondary ring gear (3) on a side cylindrical surface of the main drive gear (2), the secondary ring gear a much smaller tooth module has as the main drive gear, which increases its number of teeth becomes an integral gear for Turbocompressor created which besides moderate speeds for the first Compressor stages very high at the same time Speeds for the smaller compressor stages realized.
- FIG.1 to FIG.5 An embodiment of the invention is shown in the drawings FIG.1 to FIG.5 and is explained in more detail below:
- the drawings represent an integral Gratings for a multi-stage turbocompressor or for a combination turbo compressor
- About the drive shaft (1) become a main drive gear (2) and a shrunk-on secondary gear (3) driven.
- the root circle of the secondary gear (3) is larger than the tip circle the main drive gear (2).
- the tooth module of the secondary gear (3) is much smaller than the tooth module the main drive gear (2), accordingly the number of teeth is (3) much larger than the number of teeth from (2).
- the pinion shafts (4) and (5) are standing with the main drive gear (2) engaged, the pinion shafts (6) and (7) comb with the secondary ring gear (3).
- Combinations e.g. Basic compressor three or four-stage, first additional compressor two-stage, second additional compressor two-stage.
