Description
Technical field
This utility model relates to the foundry goods in machine casting field, whole particularly to a kind of straddle-type single-track vehicle output shaft
Body formed steel-casting.
Background technology
Output shaft is a vitals of straddle-type single-track vehicle, and the quality of its quality directly influences light rail train
Properly functioning.Require according to output shaft technical standard: foundry goods general tolerance GB/T6414-CT8 level；Foundry goods must not have pore, contracting
The defects such as pine, crackle, burning into sand, misrun, cold shut；Foundry goods artificial aging processes, hardness HB220～270；Linear and Angular Dimension
Tolerance presses GB/T1804-m level；The tolerance of shape and position presses GB/T1184-G level；Balance quality of rigid rotor ISO 1940-1；
Perform by balance accuracy grade G16, initial unbalance,≤300g, during balance, use weighting procedure.
Being easily generated the defect such as shrinkage cavity, pore for this foundry goods its main body section in casting process, port, ring flange easily produce
The defects such as raw slag inclusion, misrun, cold shut.Miss additionally, be easily generated Concentricity tolerance, location floral disc etc. point when the later stage is processed
Difference, does not reaches design requirement, to such an extent as to floral disc difficulty of processing is big, yield rate is low in location, and production cost is higher.
Summary of the invention
The purpose of this utility model is to overcome drawbacks described above, it is provided that the output shaft of a kind of new structural design so that it is in casting
The generation of casting flaw can be greatly reduced during making.
This utility model is achieved through the following technical solutions: a kind of straddle-type single-track vehicle output shaft global formation cast steel
Part, including axis body, outer circumferential surface configuration one ring flange of described axis body, axis body is divided into long axis body and short axle by ring flange
Body, the outer circumferential surface configuration of described short axis body has 6 location floral discs, location floral disc is provided with floral disc groove.
Further, on described short axis body, hollow cylindrical rising head at its axis centre, it is provided with.
Further, described 6 location floral disc even angle at equal intervals are arranged.
Further, the degree of depth of described hollow cylindrical rising head is more than 1/2nd of short axis body height.
Further, described long axis body, short axis body, the concentricity of position floral disc three are not more than 0.1mm.
Compared with prior art, the beneficial effects of the utility model are:
Short axis body port is provided with hollow column type rising head, and the design of rising head can be to short axis body, ring flange and location floral disc
Carry out good feeding, decrease the formation of pore, shrinkage cavity, slag inclusion, misrun, cold shut；Meanwhile, flower is devised at location floral disc
Dish groove, is beneficial to alleviate short axis body overall weight first, is second prone to the position utilizing groove to confirm location floral disc, is beneficial to control
Location floral disc and short axis body, long axis body and the concentricity of ring flange, it is ensured that the casting accuracy of foundry goods.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Detailed description of the invention
Below in conjunction with the accompanying drawings and detailed description of the invention the present invention will be further described.
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing and enforcement
Example, is further elaborated to this utility model.Should be appreciated that specific embodiment described herein is only in order to explain this
Utility model, is not used to limit this utility model.
As it is shown in figure 1, the utility model discloses a kind of straddle-type single-track vehicle output shaft global formation steel-casting, including
Axis body, outer circumferential surface configuration one ring flange 2 of described axis body, axis body is divided into long axis body 1 and short axis body 3, institute by ring flange 2
The outer circumferential surface configuration stating short axis body 3 has 6 location floral discs 4, and location floral disc 4 is provided with floral disc groove 41.
As a preferred version of the present embodiment, on described short axis body 3, it is provided with hollow cylindrical at its axis centre and emits
Mouth 31.The degree of depth of hollow cylindrical rising head 31 is more than 1/2nd of short axis body 3 height, and the setting of hollow cylindrical rising head 31 is easy to mend
Contracting, reduces the formation of casting defect as far as possible.
As this utility model preferred embodiment, described 6 location floral disc 4 even angle at equal intervals are arranged.6 fixed
The uniformity of position floral disc 4 directly influences position and the dynamic balancing index of connecting hole.Therefore not core shift is ensured at styling step,
It is additionally arranged floral disc groove 41, it can be ensured that all indexing of location floral disc 4.
This utility model uses ZG25CrNiMo material disposably to cast global formation, uses metal pattern and the work of half essence casting
Skill scheme；Simultaneously for ensureing cast inside quality, strengthen dead head size, increase the sizing chill of axis body, make full use of metal
Self gravitation make it fill die cavity, increase cast-internal compactness, it is to avoid pore, the casting flaw such as loose occur.And rear
Phase, such global formation casting stress was evenly distributed, and has the highest damping property and resistance to impact through modifier treatment.
Shaped article after this casting, long axis body, short axis body, the concentricity of position floral disc three are not more than 0.1mm, warp
100% defect detecting test, after 100% ultrasonic examination inspection, credit rating can reach more than 2 grades, computing ballance correction≤17.6 g m.
This product can carry out industrialization, forms autonomous production ability, it is achieved exchange with imported product progressively substituting import one product.
Above description is to explanation of the present utility model, is not to restriction of the present utility model, and this utility model is limited
Scope see claim, in the case of this utility model basic conception, this utility model can make other shape
The amendment of formula.
