Abstract
The utility model discloses a kind of formula to rivet nozzle ring assembly, including bonnet, spacer sleeve and blade seat, the bonnet and the blade seat rivet to form an entirety by described spacer sleeve two, it is characterized in that, the bonnet is straight mouth cylindrical structure, the internal diameter of the straight mouth cylindrical structure is more than the internal diameter of the spacer sleeve, and the bonnet forms the step surface coordinated with the seam face of turbine box towards the end face inner edge of turbine box.The utility model compared with prior art, reduces the difficulty of processing of bonnet, reduces the range intervals of intersecting point dimension, improves the uniformity of product, while reduces cost, improves efficiency of assembling.
Description
Technical field
It the utility model is related to turbo-charger technical field, more particularly to a kind of integral type suitable for turbocharger
Rivet nozzle ring assembly.
Background technology
With the continuous upgrading of discharge, there is increasing main engine plants' selection to use variable-area turbocharger.Compare
In common booster, variable-area turbocharger can effectively improve transient response, hoisting power fuel economy and power,
It is to meet one of maximally efficient means that state more than V discharges.
Nozzle ring assembly is the core part of variable-area turbocharger.With the change of engine operating condition, nozzle ring
Blade under ECU instruction can the suitable aperture of adjust automatically to meet the requirement of engine.
As shown in Figures 1 and 2, it is main that it includes bonnet 1, spacer sleeve 2, blade seat 3 etc. to existing nozzle ring assembly
Part.Bonnet 1 and blade seat 3 rivet to form an entirety by the two of spacer sleeve 2.Bonnet 1 has axial cylinder portion 1a and circumference
Ring portion 1b.Nozzle ring assembly is assembled as shown in figure 3, axially by the A end faces rigid contact and heat shield of turbine box 9 booster
5 Elastic Contacts position, and are radially limited by 2 or 3 alignment pins 6.To prevent exhaust gas leakage, bonnet 1 axial cylinder portion 1a with
One sealing ring 7 is installed between turbine box 3.The endoporus of bonnet 1 is processed into the size of R profiles 8 and matched with the appearance and size of turbine rotor 4
Close.
Problems be present in said structure：1st, booster is higher for the fit dimension area requirement of profile, R overall sizes
Covered after being put into and add quantity again when calculating dimension chain, cause size section bigger, cause the bad control of homogeneity of product,
The difficulty of processing of bonnet is complicated simultaneously；2nd, sealing ring is installed between bonnet and turbine box causes cost to increase, while adds one
Road station, efficiency of assembling are relatively low.
Utility model content
The purpose of this utility model is above-mentioned deficiency and defect for prior art, there is provided a kind of integral type riveting spray
Mouth ring assembly, to solve the above problems.
The technical problem that the utility model solves can be realized using following technical scheme：
Integral type rivets nozzle ring assembly, including bonnet, spacer sleeve and blade seat, the bonnet and the blade seat pass through
Described spacer sleeve two rivets to form an entirety, it is characterised in that the bonnet is straight mouth cylindrical structure, the straight mouth cylinder
The internal diameter of structure is more than the internal diameter of the spacer sleeve, and the bonnet forms the seam with turbine box towards the end face inner edge of turbine box
The step surface that face coordinates.
As a result of technical scheme as above, the utility model compared with prior art, reduces the difficulty of processing of bonnet,
The range intervals of intersecting point dimension are reduced, improve the uniformity of product, while reduce cost, improve efficiency of assembling.
Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, drawings in the following description are only

Fig. 2 is Fig. 1 A-A sectional views.
Fig. 3 is structural representation of the nozzle ring general assembly of prior art in turbocharger.
Fig. 4 is a kind of structural representation of embodiment of the utility model.
Fig. 5 is Fig. 4 A-A sectional views.
Fig. 6 is the structural representation that a kind of embodiment of the utility model is assemblied in turbocharger.
Embodiment
In order that technological means, creation characteristic, reached purpose and effect that the utility model is realized are easy to understand, under
The utility model is expanded on further in face.
Nozzle ring assembly, including bonnet 10, spacer sleeve 20 and blade seat 30 are riveted referring to the integral type shown in Fig. 4-6, after
Lid 10 and blade seat 30 rivet to form an entirety by the two of spacer sleeve 20.Bonnet 10 is straight mouth cylindrical structure, straight mouth cylinder
The internal diameter of structure is more than the internal diameter of spacer sleeve 20, and bonnet 10 forms the seam with turbine box 40 towards the end face inner edge of turbine box 40
The step surface 11 that face 41 coordinates.
When the utility model and turbocharger are used cooperatively, the utility model is axially by the B end faces of turbine box 40
The rigid contact of seam face 41 and the positioning of the elastic deformation of heat shield 50, are radially limited by 2 or 3 alignment pins 60, seam face 41
The dimensional fits of R profiles 80 of inner face and the form fit of turbine rotor 70.The utility model compared with prior art, reduces bonnet
Difficulty of processing, reduce the range intervals of intersecting point dimension, improve the uniformity of product, while reduce cost, improve
Efficiency of assembling.
The advantages of general principle and principal character of the present utility model and the utility model has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification
Simply illustrate principle of the present utility model, on the premise of the spirit and scope of the utility model is not departed from, the utility model is also
Various changes and modifications are had, these changes and improvements are both fallen within claimed the scope of the utility model.The utility model
Claimed scope is by appended claims and its equivalent thereof.
