Abstract
The utility model relates to a square shift block driving type nozzle ring with a variable cross section. The nozzle ring comprises a driving disc and a nozzle ring base, wherein the periphery of the nozzle ring base is uniformly provided with blades and driven rocking arms, the blades are respectively in clearance fit with the nozzle ring base, and the back part of the driving disc is connected with a lining plate structure through a distance sleeve; in addition, the nozzle ring base is uniformly provided with a plurality of clamp openings, and each clamp opening is respectively provided with one driven rocking arm and is connected with each blade by the driven rocking arm; and meanwhile, each driven rocking arm is provided with a square clamp opening groove, the inside of each square clamp opening groove is provided with a driven square shift block, the driven square shift blocks are serially connected through driven cushion sheets and driven shift shafts and then are welded and fixedly arranged on the driving disc, and the disc surface of the driving disc is provided with driving square shift blocks which are respectively in mismatch arrangement with the driven square shift blocks. The nozzle ring has the advantages that the process is simple, the processing is convenient, the assembly is easy, the energy loss is less, and the operation efficiency is high.
Description
Technical field
The utility model relates to the supercharging of internal combustion engine equipment unit, is specially a kind of side's shifting block drive-type nozzle ring capable of changing cross sections.
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 critical 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 component with variable cross section type of belt drive is conventional driving, drive plate was relaxed with connecting comparatively of inter-module, walked under the high temperature or blade skids off, the sunken trouble such as blade incoordinate movement, and the energy loss of airflow strikes on blade is larger, and efficient is not high.Thereby need to design a kind of novel nozzle ring assembly with since overcome this defective.
The model utility content
The technical problem that the utility model solves is to provide a kind of side's shifting block drive-type nozzle ring capable of changing cross sections, this variable nozzle ring can guarantee reliability when high temperature and high speed moves, resistance to motion is less with respect to traditional nozzle ring component with variable cross section simultaneously, the blade action consistency is also better, to solve the shortcoming in the above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions:
Side's shifting block drive-type nozzle ring capable of changing cross sections, 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, then be connected on the lining plate structure by spacer sleeve at the drive plate rear portion; In addition, on the nozzle ring pedestal, also evenly have some bayonet sockets, and be provided with driven rocking arm at each bayonet socket, and connect blade by driven rocking arm; Simultaneously, have square bayonet slot on the described driven rocking arm, be provided with driven side's shifting block in it, driven side's shifting block is by being weldingly fixed on the drive plate after the series connection of mobile gasket and driven shifting shaft, and at the card of drive plate master side's shifting block that also to be provided with driven side's shifting block be arranged in dislocation.
In the utility model, described driven side's shifting block, directly be enclosed within on the nozzle ring pedestal from mobile gasket and driven shifting shaft, can freely rotate.
In the utility model, adopt movingly between described driven side's shifting block and the driven rocking arm.
In the utility model, described blade and driven rocking arm are corresponding arranging one by one.
Beneficial effect: the utility model resistance to motion when work is less, the compacter blade action consistency of transmission is better, the higher relative friction forces that has reduced between drive plate and driven rocking arm of assembly high-temperature reliability, required driving force is less, is conducive to nozzle ring assembly stable operation and improves speed of response.
