Description
Technical field
Rotating shaft field is the utility model is related to, more particularly to a kind of automobile-used streamline intermediate rotary shaft.
Background technology
The common generally pylindrical rotating shaft of rotating shaft is arranged concentrically but the rotating shaft of various outer diameter with multistage, this rotating shaft
Raw material flow liner is cut off, and inside parts stress is easily concentrated after stress is assembled, and easily has crack fracture phenomenon.
Utility model content
The purpose of this utility model is above-mentioned deficiency and defect for prior art, there is provided turns among a kind of streamline
Axle, to solve the above problems.
The technical problem that the utility model solves can be realized using following technical scheme：
Streamline intermediate rotary shaft, it is characterised in that including from first end to the second end be sequentially coaxially provided with plush copper, axle journal,
Axle body, spacer flanger, axle tail, the external diameter of the axle journal are less than the external diameter of the axle body, and the external diameter of the axle tail is less than the axle
The external diameter of body but the external diameter for being greater than the axle journal, the spacer flanger are arranged between axle body and the axle tail, the axle journal
With smooth conical surface transition between axle body, flat groove is provided with the outside of the axle tail.
In a preferred embodiment of the present utility model, the plush copper include sequentially coaxially integrally formed cylinder portion and
Truncated hemisphere portion, the external diameter in the cylinder portion are equal with the external diameter of the axle body.
As a result of technical scheme as above, pivot structure of the present utility model is reasonable, by between axle journal and axle body
The technical scheme connected with smooth conical surface transition, it is streamlined, cold-heading easy-formation can be made, and inside parts should after assembling stress
Power does not have concentration, will not crack and fail.
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
It is some embodiments of the utility model, for those of ordinary skill in the art, is not paying the premise of creative work
Under, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is a kind of structural representation of embodiment of the utility model.
Fig. 2 is use state installation diagram of the present utility model.
Fig. 3 is Fig. 2 A-A to sectional view.
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.
Sequentially coaxially set referring to a kind of automobile-used streamline intermediate rotary shaft shown in Fig. 1 to Fig. 3, including from first end to the second end
Plush copper 100, axle journal 200, axle body 300, spacer flanger 400, axle tail 500 are equipped with, the external diameter of axle journal 200 is less than the outer of axle body 300
Footpath, the external diameter of axle tail 500 are less than the external diameter of axle body 300 but are greater than the external diameter of axle journal 200, and spacer flanger 400 is arranged on axle body
Between 300 and axle tail 500, with the smooth transition of the conical surface 600 between axle journal 200 and axle body 300, the outside of axle tail 500 is provided with flat
Rise as high as the banks 510.
Preferably, plush copper 100 includes sequentially coaxially integrally formed cylinder portion 110 and truncated hemisphere portion 120, cylinder portion
110 external diameter is equal with the external diameter of axle body 300.
Operation principle of the present utility model is as follows：
During assembling, pilot hole 1a and the axle tail 500 of metal plate connector 1 coordinate, and spacing by spacer flanger 400, while metal plate
Junction among the pilot hole 1a and axle tail 500 of golden connector 1 is by being welded and fixed, now because the outside of axle tail 500 is set
It is equipped with flat groove 510 so that leave assembly space 511 between the inner of flat groove 510 and metal plate connector 1, avoid interference with.And
The pilot hole 2a of rocking arm 2 coordinates with axle journal 200, by the inner jointly spacing with the front end of the smooth conical surface 600 of plush copper 100, passes through
The technical scheme connected between axle journal and axle body with smooth conical surface transition, raw material flow liner is continuous, continuous streamlined, can make
Cold-heading easy-formation, and inside parts stress does not have concentration after assembling stress, will not crack and fail.
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.
