Abstract
The utility model provides a wear-resistant and high-temperature-resistant variable section nozzle ring component, which comprises a driving disc and a nozzle ring base, wherein three supporting shafts are evenly arranged on the nozzle ring base and are fixedly mounted on the nozzle ring base; the two ends of the supporting shafts are respectively connected with vanes and driven rocker arms; the vanes are in clearance fit with the nozzle ring base and are fixedly arranged on the nozzle ring base through a welded manner; the driving disc is mounted in clamping groove space among the three supporting shafts; meanwhile, a plurality of position limiting sheets are additionally arranged on a disc surface of the driving disc; and a plurality of poking pins are additionally and evenly arranged on the edge of the disc surface of the driving disc. The wear-resistant and high-temperature-resistant variable section nozzle ring component has the advantages of simplicity in process, convenience in machining, easiness in assembly and compactness in overall structure, and is not easy to deform and loosen even under the condition of high-temperature long-time working.
Description
Technical field
The utility model relates to a kind of vehicle engine booster equipment unit, is specially a kind of Wear-resistant, high-temperature resistant nozzle ring component with variable cross section.
Background technique
Turbosupercharging is one of world's internal-combustion engine technology developing direction, and turbocharging technology can increase substantially engine output, and energy saving reduces engine exhaust and pollutes.And nozzle ring component with variable cross section is the key component in the current advanced turbosupercharger, the operating characteristics when its quality and structure directly affect pressurized machine service behaviour and installation and maintenance.But the easily distortion in high temperature and the larger situation of loading of the drive plate of conventional driving nozzle ring assembly, simultaneously, its wear-resisting property is also relatively poor, and the axial twist distortion also occurs in its blade easily, thus it is not smooth even stuck to cause nozzle ring to rotate.
The model utility content
The technical problem that the utility model solves is to provide a kind of Wear-resistant, high-temperature resistant nozzle ring component with variable cross section, to solve the shortcoming in the above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions:
A kind of Wear-resistant, high-temperature resistant nozzle ring component with variable cross section, comprise drive plate and nozzle ring pedestal, wherein, on the nozzle ring pedestal, evenly be provided with three back shafts, back shaft is fixedly mounted on the nozzle ring pedestal, its two ends connect respectively blade and driven rocking arm, adopt Spielpassung between blade and the nozzle ring pedestal and be fixed on the nozzle ring pedestal by welding manner, drive plate then is installed in three draw-in groove spaces between the back shaft, simultaneously, on the card of drive plate, also be provided with some banking stops, and also evenly be provided with some pins of stirring at the card edge of drive plate.
In the utility model, be arranged in dislocation between described back shaft and the banking stop.
In the utility model, described back shaft and banking stop all adopt wear-resistant ceramic material to make, and scribble one deck high molecular abrasion-proof coating at its edge.
Beneficial effect: the utility model compact overall structure, the blade action consistency is good, assembly reliability under the high temperature high load is higher, it is compacter that drive plate and driven rocking arm are cooperated when work, thereby minimizing cooperates not smooth and stuck phenomenon because of drive plate with driven rocking arm, the conformity of blade rotation is better, is conducive to nozzle ring assembly stable operation and improves speed of response.
Description of drawings
Fig. 1 is the schematic representation of the utility model preferred embodiment.
Fig. 2 is the side generalized section of the utility model preferred embodiment.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Preferred embodiment referring to a kind of Wear-resistant, high-temperature resistant nozzle ring component with variable cross section of Fig. 1, Fig. 2, in the present embodiment, comprise drive plate 1, nozzle ring pedestal 2, embedding groove 3, driven Rocker arm 4, stir pin 5, banking stop 6, spacing axle 7, blade 8, liner plate 9 and back shaft 10.
Stirring pin 5 is welded on the drive plate 1, locate one by one with driven Rocker arm 4 and to cooperate, and back shaft 10 is fixedly mounted on the nozzle ring pedestal 2, its two ends connect respectively blade 8 and driven Rocker arm 4, driven Rocker arm 4 and blade 8 welding and nozzle ring pedestal 2 Spielpassung, spacing axle 7 one head threads are connected on the nozzle ring pedestal 2, and other end and liner plate 9 are welded and fixed, thereby form the whole nozzle ring capable of changing cross sections of a compact type.
More than show and described basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
