Embodiment
It is an object of the invention to provide a kind of manufacturing process of gear, the structure design of the manufacturing process of the gear can be with
Efficiently solve plant equipment maintenance cost it is higher the problem of.
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
Fig. 1-Fig. 4 is referred to, the manufacturing process of gear provided in an embodiment of the present invention includes step：
S1 the flank of tooth 1 and the tooth heart 2) are individually processed；
I.e. it is separately machined go out the flank of tooth 1, it is separately machined go out the tooth heart 2, the flank of tooth 1 and the independently machine-shaping of the tooth heart 2.So add
Work, the processing of the flank of tooth 1 and the tooth heart 2 are independent of each other, and operation is more flexible.
S2) flank of tooth 1 and the tooth heart 2 are fixed together, and the flank of tooth 1 after being fixedly connected and the tooth heart 2 are coaxially disposed.
The flank of tooth 1 of machine-shaping and the tooth heart 2 are fixed together and to form gear.Also, the flank of tooth 1 after being fixedly connected
It is coaxially disposed with the tooth heart 2 and the flank of tooth 1 is set in the outside of the tooth heart 2, multiple teeth is provided with the excircle of the flank of tooth 1.
During the gear processed using gear manufacturing technology provided in an embodiment of the present invention, when gear and the flank of tooth 1 wherein
One when going wrong, can be individually replaced the flank of tooth 1 or the tooth heart 2, it is not necessary to integral replacing gear again, greatly reduce maintenance into
This.
In one embodiment, step S2) be specially：
The flank of tooth 1 and the tooth heart 2 are linked together by interference fit, and the flank of tooth 1 after being fixedly connected and the tooth heart 2 are coaxially set
Put.
The flank of tooth 1 can be realized into both be fixedly connected with the tooth heart 2 by being interference fitted.
Further, in process, the flank of tooth 1 of shaping can be heated uniformly to more than design temperature, then by tooth
The heart 2 loads in the centre bore of the flank of tooth 1, finally cooling down together with the flank of tooth 1 can make the tooth heart 2 and the obvolvent of the flank of tooth 1 with one heart.
Wherein, design temperature is 250 DEG C, naturally it is also possible to the concrete numerical value of design temperature is set according to actual conditions,
This is not construed as limiting.
Certainly, the flank of tooth 1 and the tooth heart 2 can also be fixed together otherwise, such as clamping etc., not made herein
Limit.
Gear is higher than the hardness requirement to the tooth heart 2 in actual use, to the hardness requirement of the flank of tooth 1, thus be accordingly used in plus
The hardness of the material of the work flank of tooth 1 is more than the hardness for the material for being used to process the tooth heart 2.
In addition, gear is in actual use, the intensity requirement to the flank of tooth 1 is higher than to the intensity requirement of the tooth heart 2, therefore use
It is more than the intensity for the material for being used to process the flank of tooth 1 in the intensity of the material of the processing tooth heart 2.In this way, can be according to the tooth heart 2 and tooth
The specific requirement in face 1, two kinds of different materials are selected to process the tooth heart 2 and gear respectively.
Preferably, for process the tooth heart 2 material toughness also above the material for processing the flank of tooth 1 toughness, herein
It is not construed as limiting.
During processing gear, the flank of tooth 1 and the tooth heart 2 can be respectively by two kinds of steel manufacture processing shapes of different model
Into to meet the hardness requirement to the flank of tooth 1 and the intensity requirement to the tooth heart 2 in actual use.Certainly, the tooth heart 2 and the flank of tooth 1
It can also be processed and formed, is not limited thereto by same material.
For the ease of being further opened with axis hole 2a with the centre position of axis connection, wherein the tooth heart 2.Axis hole 2a can be circular hole,
It can certainly be waist-shaped hole.
Each embodiment is described by the way of progressive in this specification, what each embodiment stressed be and other
The difference of embodiment, between each embodiment identical similar portion mutually referring to.
The foregoing description of the disclosed embodiments, professional and technical personnel in the field are enable to realize or using the present invention.
A variety of modifications to these embodiments will be apparent for those skilled in the art, as defined herein
General Principle can be realized in other embodiments without departing from the spirit or scope of the present invention.Therefore, it is of the invention
