Description
Technical field
This utility model relates to turbine assembly attachment structure field, particularly to one utilize electron beam weldering connect turbine and
The structure of axle.
Background technology
The turbine of the most common turbocharger mostly is friction welding (FW) with the connection of axle and welds.This welding manner is mainly
First being linked into an integrated entity by friction welding (FW) with axis blank by turbine blank, weld can form the crator of projection, follow-up cuts on request
Ream crator, then machine axle.
Above-mentioned connected mode has the disadvantage in that
1) friction welding (FW) welding causes turbine and axle be not concentric, and axle machine adds the problem that surplus is big；
2) need to cut crator, technique duration, inefficiency.
Utility model content
The purpose of this utility model is the above-mentioned deficiency for prior art and defect, it is provided that one utilizes electron beam to weld
Connect turbine and the structure of axle, to solve the problems referred to above.
This utility model is solved the technical problem that to realize by the following technical solutions:
A kind of utilizing electron beam weldering to connect turbine and the structure of axle, including axle and turbine, described axial plane is to described turbine
One end has a big shaft part, and described big shaft part is the first solder side towards one end of described turbine, it is characterised in that described first
The outer peripheral face of solder side receives tapered slope in being set to first, and in the middle part of described turbine, the one end towards described big shaft part is the second weldering
Junction, the outer peripheral face of described second solder side is set to and receives the second joint face that tapered slope matches, institute in described first
State receive in first the minimum diameter of tapered slope identical with the maximum gauge of described second joint face or described first in receive and bore
The minimum diameter on shape inclined-plane, slightly larger than the maximum gauge of described second joint face, receives the maximum gauge of tapered slope in described first
Identical with the external diameter of described big shaft part, receive the outer peripheral face junction employing of tapered slope and described second joint face in described first
Electron beam weldering connects to be formed welds scar ring, and the external diameter of described welding scar ring is less than the external diameter of described big shaft part.
Owing to have employed technical scheme as above, compared with this utility model and friction welding (FW) weld, there is a following significant advantage:
1) can reduce the welding caused because of friction welding (FW) welding to misalign, axle machine adds the problem that surplus is big；
2) crator caused because of friction welding (FW), the problem of cutting crator can be removed from；
3) preparation is simple, can be prepared in advance and machine axle and turbine and assembling jig, convenient operation.

Detailed description of the invention
For the technological means making this utility model realize, creation characteristic, reach purpose and be easy to understand with effect, under
Face is expanded on further this utility model.
See shown in Fig. 1 to Fig. 4 a kind of utilizes electron beam weldering to connect turbine and the structure of axle, including axle 100 and turbine
200, axle 100 has a big shaft part 110 towards one end of turbine 200, and big shaft part 110 is the first weldering towards one end of turbine 200
Junction 111, the outer peripheral face of the first solder side 111 receives tapered slope 112 in being set to first.
In the middle part of turbine 200, the one end towards big shaft part 110 is the second solder side 210, and the outer peripheral face of the second solder side 210 sets
It is set to and in first, receives the second joint face 211 that tapered slope 112 matches.The minimum diameter of tapered slope 112 is received in first
The maximum dimension D 3 of D2 and the second joint face 211 identical or first in receive the minimum diameter D2 of tapered slope 112 slightly larger than the
The maximum gauge of two joint faces 211, the maximum dimension D 1 receiving tapered slope 112 in first is identical with the external diameter of big shaft part 110.The
Receive tapered slope 112 in one uses electron beam weldering to be connected formation welding scar ring with the outer peripheral face junction of the second joint face 211
300, the outer diameter D 4 of welding scar ring 300 is less than the external diameter (receiving the maximum dimension D 1 of tapered slope 112 in i.e. first) of big shaft part.
Owing to have employed technical scheme as above, compared with this utility model and friction welding (FW) weld, there is a following significant advantage:
1) can reduce the welding caused because of friction welding (FW) welding to misalign, axle machine adds the problem that surplus is big；
2) crator caused because of friction welding (FW), the problem of cutting crator can be removed from；
3) preparation is simple, can be prepared in advance and machine axle and turbine and assembling jig, convenient operation.
