During the engine assembly, the injection pump gear need be with injection pump connection pad assembly together work, in the assembling process, because the existence of injection pump connection pad, often can bring not little degree of difficulty for the cooperation assembly of injection pump gear, lead to its assembly process loaded down with trivial details, on the other hand, under more and more car factories are devoted to the trend of vehicle lightweight, the injection pump connection pad has the whole weight that can increase the vehicle undoubtedly.
Therefore, it is desirable to provide a fuel injection pump gear that can reduce the difficulty of assembling an engine and satisfy the requirement of light weight of a vehicle.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a can reduce the engine assembly degree of difficulty to satisfy vehicle lightweight injection pump gear.
The utility model provides a technical problem adopt following technical scheme:
the utility model provides an injection pump gear, includes gear body and connecting portion, connecting portion set up in gear body one side to with gear body integrated into one piece.
Furthermore, the gear body comprises a wheel disc, a central through hole is formed in the wheel disc, gear teeth are formed in the disc edge of the wheel disc, a weight reduction groove is formed between the gear teeth and the central through hole, and a plurality of weight reduction holes and connecting holes are formed in the weight reduction groove.
Further, the shape of the lightening hole includes, but is not limited to, a kidney-shaped hole.
Further, connecting portion are including connecting body, connecting body is cylindrically, and has seted up the mounting hole along its axial direction, the axis of mounting hole and connecting body's axial direction coincidence, connecting body one end still is formed with the flange, flange and rim plate coaxial coupling.
Further, the diameter of the mounting hole gradually increases along the axial direction of the connecting body, and the flange is formed at one end of the mounting hole with a smaller diameter.
The utility model discloses following beneficial effect has: the utility model discloses a fuel injection pump gear has alleviateed the weight of engine fuel injection pump front end on the one hand through redesign original fuel injection pump gear and fuel injection pump connection pad, makes whole car satisfy lightweight requirement better, and on the other hand can also reduce the process of commentaries on classics joining in marriage, has improved production efficiency greatly.

Detailed Description
The technical solution of the present invention will be further explained with reference to the following embodiments and accompanying drawings.
Example 1
The embodiment provides a fuel injection pump gear is used for solving the problem of the assembly difficulty that the existence of fuel injection pump connection pad brought, simultaneously can also be fine for engine body weight reduction, further make whole car satisfy the lightweight design.
As shown in fig. 1-2, the fuel injection pump gear comprises a gear body and a connecting portion, wherein the connecting portion is arranged on one side of the gear body and is integrally formed with the gear body.
The utility model discloses an in the embodiment, the gear body passes through flange and is connected with the signal disc, and connecting portion replace the direct and transmission shaft connection of injection pump connection pad to constitute the injection pump front end jointly.
Specifically, the gear body comprises a wheel disc 1, a central through hole 2 is formed in the wheel disc 1, gear teeth 3 are formed in the disc edge of the wheel disc 1, a weight reduction groove 4 is formed between the gear teeth 3 and the central through hole 2, and a plurality of weight reduction holes 5 and connecting holes 6 are formed in the weight reduction groove 4.
In the embodiment of the present invention, the lightening holes 5 are used to lighten the weight of the gear body, so that the gear body can satisfy the lightening of vehicle parts; the connecting hole 6 is used for fixedly connecting the gear body with the signal panel. On the other hand, a plurality of lightening holes 5 and connecting holes 6 are uniformly arranged in the lightening grooves 4, so that the center of gravity of the gear body is not deviated, and the stability of the gear body in rotation is ensured. Preferably, the shape of the lightening hole 5 includes, but is not limited to, a kidney-shaped hole.
Connecting portion are including connecting body 7, connecting body 7 is cylindrical, and has seted up mounting hole 8 along its axial direction, the axis of mounting hole 8 and connecting body 7's axial direction coincidence, connecting body 7 one end still is formed with flange 9, flange 9 and rim plate 1 coaxial coupling.
In the embodiment of the present invention, the mounting hole 8 is used for connecting the oil injection pump gear with the transmission shaft; the diameter of the mounting hole 8 gradually increases along the axial direction of the connecting body 7, and the flange 9 is formed at the end of the mounting hole 8 with the smaller diameter.
The utility model discloses a fuel injection pump gear has alleviateed the weight of engine fuel injection pump front end on the one hand through redesign original fuel injection pump gear and fuel injection pump connection pad, makes whole car satisfy lightweight requirement better, and on the other hand can also reduce the process of commentaries on classics joining in marriage, has improved production efficiency greatly.
The sequence of the above embodiments is only for convenience of description and does not represent the advantages and disadvantages of the embodiments.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
