In conclusion the higher problem of the maintenance cost for how efficiently solving mechanical equipment, is current art technology
Personnel's urgent problem.
Utility model content
In view of this, first of the utility model is designed to provide a kind of gear, the structure design of the gear can be with
Efficiently solve the higher problem of maintenance cost of mechanical equipment.
In order to reach above-mentioned first purpose, the utility model is provided the following technical solutions：
A kind of gear, the flank of tooth and the tooth heart including coaxial arrangement are fixed after the flank of tooth and the independent machine-shaping of the tooth heart to connect
It is connected together, the flank of tooth is set on the outside of the tooth heart and the excircle of the flank of tooth and is provided with multiple teeth.
Preferably, in said gear, the flank of tooth and tooth heart interference fit.
Preferably, in said gear, the hardness of the material of the flank of tooth is greater than the hardness of the material of the tooth heart.
Preferably, in said gear, the intensity of the material of the tooth heart is greater than the intensity of the material of the flank of tooth.
Preferably, in said gear, the flank of tooth and the tooth heart are formed by two kinds of steel manufacture processing of different model respectively.
Preferably, in said gear, the middle position of the tooth heart offers axis hole.
Gear provided by the utility model includes the flank of tooth and the tooth heart, and the flank of tooth and the tooth heart are coaxially disposed.The flank of tooth is set in
The outside of the tooth heart, and multiple teeth are provided on the excircle of the flank of tooth.Focus on, it is solid after the flank of tooth and the independent machine-shaping of the tooth heart
Surely it links together, i.e., first independently processes the tooth heart and the flank of tooth, after the tooth heart and the flank of tooth are processed into type, then by molding tooth
The heart and the flank of tooth are fixed together.So set, when gear and the flank of tooth one of them when something goes wrong, can be individually replaced
The flank of tooth or the tooth heart, it is not necessary to which integral replacing gear again greatly reduces maintenance cost.

Specific embodiment
First of the utility model is designed to provide a kind of gear, and the structure design of the gear can efficiently solve
The higher problem of the maintenance cost of mechanical equipment.
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Please refer to Fig. 1-Fig. 4, gear provided by the embodiment of the utility model includes the flank of tooth 1 and the tooth heart 2, and 1 He of the flank of tooth
The tooth heart 2 is coaxially disposed.The flank of tooth 1 is set in the outside of the tooth heart 2, and multiple teeth are provided on the excircle of the flank of tooth 1.With emphasis on
In being fixed together after the flank of tooth 1 and the independent machine-shaping of the tooth heart 2, i.e., first process the tooth heart 2 and the flank of tooth 1, the tooth heart 2 respectively
After being processed into type with the flank of tooth 1, then the molding tooth heart 2 and the flank of tooth 1 be fixed together.So set, working as gear and tooth
One of them of face 1 when something goes wrong, can be individually replaced the flank of tooth 1 or the tooth heart 2, it is not necessary to which integral replacing gear again substantially reduces
Maintenance cost.
Preferably, the flank of tooth 1 can realize being fixedly connected for the two by interference fit with the tooth heart 2.It, can be in process
250 DEG C or more are heated uniformly to the molding flank of tooth 1, then the tooth heart 2 is packed into one heart to the flank of tooth 1, finally cools down the flank of tooth 1
Make the tooth heart 2 together with 1 obvolvent of the flank of tooth.
Certainly, the flank of tooth 1 and the tooth heart 2 can also be fixed together otherwise, such as clamping etc., not made herein
It limits.
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, therefore the flank of tooth 1
The hardness of material is greater than the hardness of the material of the tooth heart 2.
In addition, gear is in actual use, the intensity requirement to the flank of tooth 1, therefore tooth are higher than to the intensity requirement of the tooth heart 2
The intensity of the material of the heart 2 is greater than the intensity of the material of the flank of tooth 1.In this way, can be selected according to the specific requirement to the tooth heart 2 and the flank of tooth 1
It selects two kinds of different materials and processes the tooth heart 2 and gear respectively.
Preferably, the toughness of the material of the tooth heart 2 is not limited thereto also above the toughness of the material of the flank of tooth 1.
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
At 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 be formed, is not limited thereto by same material.
For the ease of with axis connection, wherein the middle position of the tooth heart 2 is also provided with axis hole 2a.Axis hole 2a can be circular hole,
It can certainly be waist-shaped hole.
Each embodiment in this specification is described in a progressive manner, the highlights of each of the examples are with other
The difference of embodiment, the same or similar parts in each embodiment may refer to each other.
The foregoing description of the disclosed embodiments can be realized professional and technical personnel in the field or using originally practical new
