Definitions
- the invention relates to the field of exhaust gas turbochargers for supercharged internal combustion engines.
- It relates to the housing of an axial turbine of an exhaust gas turbocharger and a method for producing such a turbine housing.
- Exhaust gas turbochargers are used to increase the performance of internal combustion engines, in particular reciprocating engines.
- an exhaust gas turbocharger usually has a centrifugal compressor and a radial or axial turbine.
- the turbine side is configured according to the requirements of the internal combustion engine.
- turbine blades with different blade heights can be provided, for example, for a given turbine size, that is to say a specific turbine wheel size and a corresponding turbine housing.
- shorter or longer blades are mounted on the blade carrier.
- turbine blades with deviating blade height are to be retrofitted into an existing exhaust gas turbine later.
- Gas outlet housing of axial turbines such as known from DE 101 37 899 C1 are usually formed as a collecting space, which has on one side in an approximately semicircular cross section, and on the opposite side a round or rectangular flange for connection to a discharge line includes.
- the object of the invention is to improve the outflow of an axial turbine with simple means fluidically.
- the housing in the outflow region, from the diffuser to the gas outlet housing is designed as a component with a combined inner and outer flow channel.
- the integration of the diffuser in the gas outlet housing a housing is created, which is aerodynamically optimized and ensures maximum flow delay with minimal pressure loss.
- the combined inner and outer flow channel is delimited by the gas outlet housing and a diffuser wall, wherein the point of intersection between the gas outlet housing and the diffuser wall according to the invention is along the circumference at different radii. This results in two, varying in the circumferential direction partial flow channels, which are responsible for the desired flow optimization.
- the diffuser has a replaceable insert in the area radially outside the rotor blades, which can be exchanged for another insert with other geometric dimensions as needed and depending on the selected turbine blade height.
- Fig. 1 shows a section through the outflow of an axial turbine with inventively integrated diffuser and gas outlet housing
- FIG. 2 shows an enlarged section of an exchangeable insert piece, which is arranged in the region radially outside the turbine blades in the diffuser.
- Fig. 1 shows the outflow region of an axial turbine.
- the housing 1 in the outflow region essentially comprises the turbine-near diffuser, which is delimited by an inner diffuser wall 12 and an outer diffuser wall 11, and the outer gas outlet housing 10, which accommodates the inner flow 13 emerging from the inner region of the diffuser and as an outer flow 14 leads to the outlet flange of the gas outlet housing.
- the task of the housing in the outflow area of the turbine is to delay the flow velocity of the exhaust gas without losing much pressure.
- the gas outlet housing 10 is integrally formed with the diffuser housing. This results in an aerodynamically optimal transition from the inner flow region 13 to the outer flow region 14.
- the region of the intersection between the gas outlet housing 10 and the outer wall 11 of the diffuser is T-shaped.
- the point of intersection T travels along the circumference of the diffuser wall, so that the outer flow channel has an unequal cross-section.
- the gas outlet housing with integrated diffuser optionally contains an insert piece 15, which is arranged in the region radially outside the turbine blades 3.
- Fig. 2 shows this area in an enlarged view. If a new blade height is provided in an axial turbine with a given housing size, ie a given integrated diffuser and gas outlet housing, the insert 15 can be exchanged to compensate for the distance between the blade tips and the housing. This can be easily, and especially without great logistical and assembly-technical effort to realize several turbine configurations with one and the same turbine size.
- the differing housing parts are only the small inserts. It does not need to be replaced large diffuser
- the insert 15 can be fastened between the diffuser outer wall and, for example, the nozzle ring 4 or the gas inlet housing 2.
- the insert can be attached to any housing piece, for example by means of screws.
- Fig. 2 it is indicated how for different lengths blades with correspondingly offset blade tips 32, the inner contour of the different inserts is moved radially inward.
- the outer fastening ring of the nozzle ring 4 is arranged upstream of the insert 15 in the flow direction.
- the inner diameter of the outer mounting ring of the nozzle ring is smaller than the inner diameter of the inner contour of the insert 15. The difference is advantageously 0.3 to 3 times the distance between the blade tips and the inner contour of the insert.
- the insert may optionally be arranged between two housing parts such that it has a certain range of motion in the radial direction. Thus, thermal stresses in the insert can be prevented. It should be noted that the insert by the adjacent housing pieces with respect
- the wall thickness of the insert is small compared to the adjacent housing parts. As a result, thermal tensions can be prevented during rapid temperature changes. Further, the difference in the thermal expansion of the insert and the turbine runner can be kept small.
- the transition between insert 15 and the outer diffuser wall 11 may be formed flat or provided with a positive or negative step.
