When existing flange coordinates with axle, flange is individually processed with axle, when mounted, due to being generally between axle and flange
For interference fit, it is necessary to be fitted the shaft into using external equipment on flange, assembly difficulty is big, can cause flange or axle during misoperation
Damage.
The utility model is elaborated with reference to Fig. 1.
The problem of the utility model is for existing flange and difficult axle assembling, is carried out to the processing mode of flange and axle
Improve, disclose a kind of novel flange, including inner circle 101, backplate 102 and cylindrical 103 composition set gradually from inside to outside
Aluminium alloy outer layer flange, the inner side of described inner circle 101 is provided with steel shaft 104, described steel shaft 104 is embedded in described inner circle
101 inboard portion are to be set on the described inner side casting of inner circle 101, described steel shaft 104 and the described side wall of inner circle 101
The corresponding screwed hole in position is equipped with, described steel shaft 104 and described inner circle 101 are threadedly attached in described screwed hole
Interior bolt 105 is connected with each other.In the utility model, steel shaft is formed for casting processing, there is inner circle, backplate and cylindrical casting shape
Into outer layer flange, outer layer flange is integrally formed mould overall structure with outer mold, inner circle is integrally formed with outer mold and adds
The mould of work steel shaft, the part that steel shaft is embedded in interior inner round side casts and formed, during casting, steel shaft and inner circle
Between can be brought into close contact, and then make it that binding ability between steel shaft and inner circle is more preferable, make the combination between steel shaft and inner circle strong
Degree is bigger, and then makes integrally-built intensity more preferable.
During due to flange connection rotating shaft, flange is by twisting force caused by rotating shaft, and the utility model is by rotating shaft in flange
Inner side casting, geometric form between the two can be strengthened, during then causing axis of rotation, flange is not easy due to turning
Twisting force caused by axle and produce defect.
Outer layer flange and rotating shaft casting are made the assembling between flange and rotating shaft simpler by the utility model, are saved
The independent assembling of flange and axle has been gone, and then has effectively saved assembly cost, has reduced flange caused by being slipped up due to assembling or axle damage
Bad the problem of.In processing, preformed hole can be set in steel shaft and inner circle, be processed in preformed hole and form internal thread, by spiral shell
Bolt is threaded in screwed hole, makes bolt connection steel shaft and inner circle, steel shaft and inner circle is interfixed from side, to improve steel
The being firmly combined with property of axle and inner circle.
Embodiment 1：
In order to improve the bond strength between steel shaft and flange, in the present embodiment, it is provided with the outside of steel shaft and is used to connect
The structure of steel shaft and outer layer flange, it is preferable that outer tube 111, described one end of outer tube 111 are set with described steel shaft 104
It is sleeved on the described outer wall of inner circle 101, the described inside side of the other end of outer tube 111 is bent to form gear along 107, described gear edge
107 are sleeved on the described outer wall of steel shaft 104.In the present embodiment, make gear that through hole is set along middle part, steel shaft is interference fitted and installed
In through hole of the gear along middle part, outer tube bolt connection or interference fit is set to be arranged on inner circle outer wall.
By setting outer tube structure, connection can be realized to inner circle and steel shaft from outside, steel shaft is stretched out into inner circle position leads to
Cross outer tube to fix, the opposing force that can disperse between steel shaft and inner circle, inner circle is by active force mistake when avoiding the steel shaft from rotating
The damage caused by concentration.
It is further preferred that in order to reduce the twisting force that inner circle is subject in steel shaft rotation process, in the present embodiment, in institute
