Abstract

In a duct apparatus for a radial-flow turbine of an exhaust gas turbocharger of a reciprocating piston-internal combustion engine, a shaft of a blade is supported to a housing portion of the duct apparatus turning toward the compressor side of a turbocharger. A spring element pushing the shaft is arranged to the front of the end of the shaft to make the top of the blade supported on a bearing surface of the housing portion.

Description

The guiding device of radial turbine
Technical field
The present invention relates to a kind of guiding device of radial turbine, be used for exhaust gas turbocharger, have and be arranged in the blade that can carry out Flow-rate adjustment in the housing by a controlling mechanism with the internal-combustion piston engine of heavy oil work.
Background technique
In the internal-combustion piston engine with heavy oil work, contain in the waste gas and might can disturb the proper functioning of adjustable vane thus attached to the solid particle on the guiding device.
Summary of the invention
Task of the present invention is the guiding device that proposes a kind of the above-mentioned type, the functional fault in the time of can avoiding blade adjustments largely.
According to the present invention, above-mentioned technical problem realizes by following measure: the neck support of blade is provided with elastic element at the guiding device housing in the part of turbocharger compressor and in the front, end of neck, and this elastic element presses neck that the upside of blade is abutted on the abutment facing of housing parts on opposite.
Be resisted against on the abutment facing with its upside constantly and the adjustment movement of blade by blade, may be scraped away attached to the solid particle on this face.In addition, can intercept and capture thermal expansion and its supporting of blade.And especially the heat load of elastic element reduces to minimum by the structure of the parts that work with neck one in the housing parts adjacent with compressor, thus the life-span of having improved elastic element.
Preferably each adjustable lever and the neck of the controlling mechanism between elastic element and blade link; Be arranged in a position of low heat loads as far as possible equally.
Preferably, insert a briquetting between the end of this elastic element facing of elastic element and neck, this briquetting plays the effect that makes elastic element and the further hot decoupling of neck.This measure can also have an axial bore by this briquetting and be strengthened, and this axial bore diameter is less than the face size of neck.
Description to embodiment provides further feature of the present invention by dependent claims with reference to accompanying drawing.
Description of drawings
Accompanying drawing shows the sectional view according to guiding device major part of the present invention.
Embodiment
In the accompanying drawing, in the face of the housing parts of unshowned turbocharger compressor represents that with 1 relative housing parts is represented with 2. Housing parts 1 and 2 defines the channel cross-section of flow channel, and waste gas flows through this flow channel along the flow direction shown in 8.In housing parts 1, fix a cushion block, constitute the bearing of a neck 4 of blade 5.Preferably, cushion block 3 and the same material of neck 4 usefulness are made.This has been avoided these parts to cause interference owing to the thermal expansion in the work is different.
In the free end front of neck 4, arranged a briquetting 6 in the housing 1.The side action that deviates from neck at briquetting 6 has an elastic element.This elastic element 7 preferably is made of a cup spring group.Briquetting 6 can be provided with a hole along the axis longitudinal extension of neck 4, and the diameter in this hole keeps minimum so that as far as possible neck 4 is arrived the heat flow of elastic element 7, thereby overcomes the interference heat affecting to this element less than the end diameter of neck 4.In the flange 9 that neck 4 has an annular towards the channel cross-section of waste gas, this flange arrangement circumferential annular groove in cushion block 3, flange surface is concordant with the respective face of housing parts 1 with cushion block 3 to the face in exhaust steam passage cross section.A groove in the outer periphery of flange 9 is embedded in a piston ring to realize sealing.
Also acted on an adjustable lever 10 on the free end that stretches out from cushion block 3 of neck 4, this adjustable lever 9 passes to adjustment movement on the blade 5 by a regulating ring 11 of controlling mechanism.Adjustable lever 10 stops moving axially of neck 4 by a nut 12 and underlaid lock washer.
Elastic element 6 is pushed the smooth rigidity abutment facing 14 that upside 13 that blade 5 makes its straight line flexibly comes to the support block 15 that is fixedly linked with housing parts 2 by neck 4.By upside 13 flexible being resisted against on the fixing abutment facing 14, when adjusting vane, scraped away attached to the solid particle on the abutment facing 14, and also irrelevant with the thermal expansion of blade 5.
