Abstract
The utility model discloses a variable section nozzle ring component of a compact type low-position driving disc. The variable section nozzle ring component comprises a driving disc and a nozzle ring base, wherein blades on the periphery of the nozzle ring base and the nozzle ring base are in gap fit and the blades are fixed on the nozzle ring base through welding; the driving disc is installed under a driven rocker arm; a spacing shaft is further arranged on the nozzle ring base; in addition, limiting sheets, side pins and an embedding groove are further arranged on the nozzle ring base; the limiting sheets are fixed on the nozzle ring base in an interference fit manner; the side pins is transversely fixed on the edge of the nozzle ring base in an interference fit manner; and the embedding groove is fixed on the driving disc in a welding manner. The variable section nozzle ring component is simple in process, convenient to process, easy to assemble, compact in whole structure and good in blade movement consistency.
Description
Technical field
The utility model relates to a kind of vehicle engine booster equipment unit, is specially a kind of compact type low level drive plate 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.Existing nozzle ring capable of changing cross sections is not in the reliable location that axially and directly makes progress, driven rocking arm comes off in drive plate easily in the large situation of at high temperature loading, and existing drive plate is installed in driven rocking arm outside, so drive plate deforms or position movement after will cause driven rocking arm to come off or stuck phenomenon, thereby job failure occurs.
The model utility content
The technical problem that the utility model solves is to provide a kind of compact type low level drive plate 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 compact type low level drive plate nozzle ring component with variable cross section, comprise drive plate and nozzle ring pedestal, wherein, be distributed with blade and driven rocking arm at nozzle ring pedestal even circumferential, adopt Spielpassung between blade and the nozzle ring pedestal and be fixed on the nozzle ring pedestal by welding manner, and drive plate is installed in driven rocking arm below, be positioned on the step of pedestal, and on the nozzle ring pedestal, also be provided with the spacing axle, described spacing axle is connected with pedestal by a hook bolt, other end and liner plate are welded and fixed, in addition, on the nozzle ring pedestal, also be provided with banking stop, limit pin and embedding groove, described banking stop interference fit is fixed on the nozzle ring pedestal, the limit pin then laterally is fixed on the edge of nozzle ring pedestal by interference fit, embedding groove is weldingly fixed on the drive plate.
In the utility model, described spacing axle is four, and evenly arranges at the liner plate marginal position.
In the utility model, the external wormwheel liner in described liner plate rear portion.During work, blade on the nozzle ring pedestal can rotate jointly around axle center separately, along with nozzle ring upper blade Angulation changes, angle and speed that the minimum actual internal area of turbo machine and exhaust enter turbine all will change, thereby change the rotating speed of turbo machine and the boost pressure of blower outlet end.
Beneficial effect: utilize nozzle ring pedestal and position limit pin drive plate to be carried out axially the location that makes progress with the footpath in the utility model, can prevent that drive plate is subjected to displacement and is out of shape under high temperature and high load, thereby avoided the driven rocking arm of nozzle ring assembly from drive plate, to deviate from and caused driving malfunction and stuck phenomenon, and because drive plate is in driven rocking arm below, another side has the step support of pedestal, the phenomenon that drive plate can not be come off, structure are more compact.
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 compact type low level drive plate 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, limit pin 5, banking stop 6, spacing axle 7, blade 8, liner plate 9 and some shifting shafts 10.
Drive plate 1 is placed in the space of nozzle ring pedestal 2 and banking stop 6 formations, and embedding groove 3 is welded on the drive plate 1, and limit pin 5 and banking stop 6 directly insert in the nozzle ring pedestal 2 fixing, so drive plate 1 has obtained axially and location radially.
Shifting shaft 10 is welded on the drive plate 1, locate one by one with driven Rocker arm 4 and to cooperate, 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, 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.
