Definitions
- the invention relates to a transmission compressor rotor for cold gas applications with a pinion shaft having a toothed segment with a toothing, at least one impeller with an impeller hub and a sealing segment arranged between the toothed segment and the impeller hub, which carries a seal.
- Turbo compressors are used in many ways in industry and power generation.
- gearboxes are used for air separation, in the oxygen and nitrogen from
- Ambient air are separated from each other.
- an air compressor sucks in the filtered air and compresses it to the required pressure. Thereafter, the air is cooled and decomposed into the main components, ie nitrogen and oxygen and a small proportion of noble gas.
- Compressor units then compress oxygen and nitrogen, for example, to feed them into a conduit system for further use.
- a labyrinth seal in particular a multi-chamber seal, is usually arranged for gas separation and for maintaining the process-side pressure between a bearing and an impeller causing the compression of the rotor.
- the impeller of the turbo-compressor is exposed to very low temperatures of below -30 0 C. In other gas separation processes temperatures below -150 0 C can be achieved. To a brittle fracture behavior at such low temperatures too avoid cold-hard materials for the production of the impeller. If low temperatures are realized in a gear compressor, not only the wheels but also the rotor shaft within the sealing areas up to the bearing points are to be protected from brittle fracture due to the low operating temperature.
- the impeller or impellers and rotor shaft in the sealing area are typically made from a high alloy cold-strength steel in cold gas applications. For reasons of manufacturability and mountability pinion shaft and wheels are made separately. So that the pinion shaft, or the rotor shaft in the toothing region, meets high mechanical requirements, it is known to produce the pinion shaft from a different material than the impeller or its hub.
- a gear compressor rotor of the aforementioned type form the sealing segment and the impeller hub, in particular the entire impeller, a common, integrally connected region of a first material and the toothed segment is formed of a second material.
- a large portion of the rotor is made of the first material, which is adapted in its properties to the operating conditions of the impeller. The risk of cold embrittlement can be avoided with this design.
- the joint between the two materials is moved very far inward in the warm-running area.
- the toothed segment is in the operating temperature range and can be made of a conventional toothing material. This leads to very small transmission dimensions and thus at low cost and also low mechanical losses.
- the turbocompressor is expediently a transmission compressor.
- the gear segment may be part of a transmission that mechanically connects the gear compressor rotor to a drive, such as an electric motor.
- the sealing segment may carry a part or a half of a seal, in particular a labyrinth seal for sealing an environment of the compressor region or impeller against a bearing of the rotor, in particular an oil bearing bearing.
- the impeller is expediently part of an overhang stage of the turbocompressor and is expediently mounted on the fly. As a result, the impeller must be sealed only on one side with respect to a rotor bearing, so that the sealing effort is kept low.
- the gear compressor rotor when the first material is a cold-tough material, which is cold-toughened than the second material.
- the impeller is thus particularly well protected against brittle fracture behavior, whereas the inner portion of the rotor shaft can be designed according to the requirements placed on it.
- the first material is in particular a cold-tough material, such as e.g. defined in the standard EN 10.269.
- the second material is harder or higher strength than the first material.
- the second material may be case hardened, nitrided or highly tempered steel, which accommodates the high mechanical requirements of a gear transmission.
- a rotor bearing is arranged in the region of the second material.
- the rotor bearing may be a radial bearing, which is designed in particular as a hydrodynamic sliding bearing.
- Such a bearing can be supplied with warm lubricating oil at the temperature of for example 45 ° C, whereby a high heat input from the rotor bearing takes place on the rotor.
- This heat input of the toothed area can be protected from the second material against a strong cooling. Due to the arrangement of the rotor bearing in the region of the second material also unnecessary greater heating of the first material and thus of the axially outer part of the rotor is avoided.
- the shaft bearing is advantageously arranged between the sealing segment and the toothed segment. Due to the bearing of the rotor outside of the teeth, a stable flying bearing of the rotor can be achieved.
- the two material areas are suitably rotatably connected to each other.
- This non-rotatable connection can be achieved by a cohesive connection, such as a weld, a frictional connection, such as a clutch, or a positive connection.
- this connection is formed by a spur gear, so that the two material areas engage one another positively. The risk of imbalance due to a welded joint or a slippage of the two areas against each other by an insufficiently strong frictional connection can be avoided.
- the rotationally fixed connection is advantageously arranged between the sealing segment and a rotor bearing, for example the radial bearing.
- Hirth connection Particularly suitable as a rotationally fixed connection between the two rotor regions or material regions of the rotor is a Hirth connection.
- Hirtharm a fixed, self-centering and detachable connection is achieved by simple means.
- the teeth of the Hirth toothing are in the sense of a non-positive Clutch static and surface to each other and are radially aligned, whereby the centering is achieved.
- a very compact connection between the rotor areas can be achieved. For traction axial tension is necessary, which in turn limits the power transmission from one area to another.
- Sealing segment 10 comprises a seal 12 in the form of a labyrinth seal.
- the impeller 6 is cantilevered and is part of an overhang stage of
- the gear compressor rotor 2 can be designed both with one and with two wheels.
- Fig. 1 can be viewed as a half-view with a mirror plane in the toothed area.
- the pinion shaft 16 ends with the lying behind the toothing second and not shown storage area.
- the gear compressor rotor 2 is part of a turbo transmission compressor with a gear that connects a drive, such as a steam turbine or an electric motor, for power transmission with the impeller 6 by a toothing 14.
- the toothing 14 of the rotor 2 is made on a pinion shaft 16, which can be divided into a toothed segment 18 and into a bearing region 20, which in turn form an inner region 22 of the rotor.
- the pinion shaft 16 carries a rotor bearing 24 in the form of a radial bearing, namely a hydrodynamic sliding bearing.
- the two areas 4, 22 are interconnected by a positive connection 26, which is indicated by an arrow. In the connection 26, the pinion shaft 16 and the impeller 6 are positively and rotatably connected to each other.
- connection 26 is designed as a Hirth connection, wherein a screw 28 presses the two areas 4, 22 of the gear compressor rotor 2 axially against each other, so that high forces and torques can be transmitted from one to the other area 4, 22 by the Hirth connection.
- the two areas 4, 22 are made of different materials.
- the impeller hub 8 and the sealing segment 10 in the outer region 4 are made of a cold-tough material, such as the cold-tough steel X8Ni9.
- the impeller hub 8 and the sealing segment 10 are made as an integral part, for example as a forging.
- a weld between the impeller hub 8 and the seal segment 10 has been omitted to avoid the risk of imbalance due to uneven stress distribution.
- the inner portion 22 and the pinion shaft 16 may be made of a case-hardened steel, for example 18CrNiMo7-6.
- a high-strength tempering steel for example 56NiCrMoV7, is also advantageous. Both the case-hardened steel and the high-strength tempering steel are particularly hard and resistant to abrasion, so that the toothing 14 has a long service life. However, these steels are only partially cold-resistant, so there is a risk of brittle fracture at very low working temperatures.
- a brittle fracture of the cold-tough steel of the outer region 4 is particularly suitable, so that the rotor shaft 2 for operation at particularly cold temperatures, for example below -30 0 C or below -120 0 C, for example, for air separation, is particularly suitable.
- the rotor bearing 24 is supplied with warm lubricating oil, so that the hydrodynamic sliding bearing of the rotor 2 is ensured. With the warm lubricating oil heat is transferred to the inner portion 22 of the rotor 2, so that it never cools in the intended operation in a temperature range, which carries the risk of brittle fracture behavior of the pinion shaft 16.
- the transmission can be designed to be particularly compact and wear-resistant.
