Description
Technical field
The present invention relates to turbocharger production field, more particularly to a kind of reduction initial computing ballance correction of core component
Assembly technology.
Background technology
Dynamic balancing is most important for turbocharger rotor, and the assembling of turbocharger core component is to its first initiating
Balance mass has significant impact, and initial magnitude height will influence to remove amount efficiency, reduce production efficiency, and the amount of going excessively can also influence
Service life to booster etc., so a kind of efficient assembly technology is needed to reduce the initial unbalance of turbocharger
Amount.
Invention content
The technical problems to be solved by the invention are to provide a kind of assembly technology for reducing the initial computing ballance correction of core component,
The initial computing ballance correction of core component is significantly reduced or even within tolerance, without the amount of going.It is simple for process, substantially increase life
Produce efficiency.
The technical solution adopted by the present invention to solve the technical problems is：A kind of reduction initial dynamic balancing of core component is provided
The assembly technology of amount, is as follows：
(I) detection of amount of unbalance is carried out to pressure impeller and turbine part, unbalanced angle is found out and carries out duplicate removal；
(II) it is marked in pressure impeller and turbine part with the corresponding position of residual unbalance, angle；
(III) amount of unbalance mark position on pressure impeller is staggered with the amount of unbalance mark position on turbine part impeller
180 ° of angles are assembled.
Further, the label in step (II) is made on the blade of pressure impeller and turbine part or on end plane.
Advantageous effect：The present invention relates to a kind of assembly technology for reducing the initial computing ballance correction of core component, by adjusting pressure
The angle that impeller, turbine part residual unbalance, position are staggered, assemble simultaneously dynamic balancing duplicate removal, reduces to greatest extent entire
The amount of unbalance in core component radially each section, improve probability of the turbocharger rotor dynamic balancing within the margin of tolerance or compared with
Few removal product quality improves core component dynamic balancing efficiency.
Description of the drawings
Fig. 1 is the structure chart of pressure impeller of the present invention；
Fig. 2 is the structure chart of turbine part of the present invention.
Specific embodiment
With reference to specific embodiment, the present invention is further explained.It should be understood that these embodiments are merely to illustrate the present invention
Rather than it limits the scope of the invention.In addition, it should also be understood that, after reading the content taught by the present invention, people in the art
Member can make various changes or modifications the present invention, and such equivalent forms equally fall within the application the appended claims and limited
Range.
As shown in Figs. 1-2, embodiments of the present invention are related to a kind of assembler for reducing the initial computing ballance correction of core component
Skill is as follows：
(I) detection of amount of unbalance is carried out to pressure impeller and turbine part, unbalanced angle is found out and carries out duplicate removal, examine
The amount of unbalance of pressure impeller small end is measured as 0.055gmm, 12.1 ° of corresponding angle, the amount of unbalance for pressing wheel backface is
0.043gmm, 354.4 ° of corresponding angle；The amount of unbalance of turbine part small end be 0.046gmm, 7.5 ° of corresponding angle, turbine portion
The amount of unbalance at the part back side be 0.084gmm, 353.4 ° of corresponding angle, (gmm i.e. gmm pronounce a gram millimeter).
(II) it is marked in pressure impeller and turbine part with the corresponding position of residual unbalance, angle, such as Fig. 1 and 2
It is shown, it is marked, marked respectively in pressure leaf with the marker pen of white or black on the blade of pressure impeller and turbine part
The uneven angle of the blade end of wheel is at 12.1 ° and the uneven angle of the blade end of turbine part is at 7.5 °；
(III) residual unbalance, mark position and residual unbalance, marker bit on turbine part impeller on impeller will be pressed
Put the assembling that the 180 ° of angles that are staggered carry out core component entirety.
After the completion of assembling, the detection of amount of unbalance is integrally carried out to core component, under lower-speed state, fixed rotating speed corresponds to
Amount of unbalance for 23mg, at high speeds, for 10mg, (dynamic balancing machine corrects out the corresponding amount of unbalance of fixed rotating speed
Unit is mg, is converted to g, and it is exactly gmm to be multiplied by correction radius).
If pressure impeller and turbine part are not staggeredly arranged, but angle coincidence assembling, then under lower-speed state, Gu
The corresponding amount of unbalance of rotating speed is determined for 29mg, and at high speeds, the corresponding amount of unbalance of fixed rotating speed is 31mg, it is seen that is staggered
Arrangement pressure impeller and turbine part, which carry out assembling, makes core component initial unbalance, have substantial degradation, particularly in high speed shape
Under state.
Specifically see following table：
Alternatively, the label in step (II) is made on the blade of pressure impeller and turbine part or end is put down
On face.
The angle that the present invention is staggered by adjusting pressure impeller, turbine part residual unbalance, position, is assembled and is moved
Duplicate removal is balanced, the amount of unbalance in entire each section of core component radial direction is reduced to greatest extent, improves turbocharger rotor and move
The probability within the margin of tolerance or less removal product quality are balanced, improves core component dynamic balancing efficiency.
