Description
Technical field
The present invention relates to gear technique field, more particularly to a kind of automobile engine injection pump Noise-reducing gear.
Background technology
Gear is that with teeth can continuously engage transmits motion and the mechanical organ of power on wheel rim.Gear is mutually engageable
Machine components with teeth, application of the gear in transmission very early there have been.In 19 end of the centurys, transform into principle and the utilization of cutting method
The successive appearance of the special purpose machine tool and cutter of this principle cutting, with the development of production, the stationarity of gear operation is taken seriously.
Gear is also the important component on injection pump of engine, but when in use often occur gear occur in rotation it is larger
Noise, the noise for eliminating gear are the places that we should be noted.
The content of the invention
The invention aims to solve shortcoming present in prior art, and a kind of automobile engine oil spout proposed
Pump Noise-reducing gear.
To achieve these goals, present invention employs following technical scheme：
A kind of automobile engine injection pump Noise-reducing gear, including gear, centre bore, institute are provided with the gear center
State and be provided with neck in centre bore, groove is additionally provided with the center bore inner wall, in the groove clamping have sealing ring, the gear
Body front and back is equipped with annular groove, is provided with rubber strip in the annular groove, being additionally provided with stress in the gear disappears
Except hole, rubber column is provided with the stress elimination hole.
Preferably, the number in the stress elimination hole is 4, and is distributed on center central point of hole for annular array.
Preferably, it is interference fit between rubber column and the stress elimination hole.
Preferably, the rubber column both ends are below gear surface.
Preferably, the annular groove that the gear front and back is provided with is set for concentric circles.
Preferably, the neck inner surface passes through Carburization Treatment.
Preferably, the groove and the sealing ring number being engaged are three, and sealing ring is elastic wear-resisting rubber
It is made.
Preferably, the outer surface of the rubber strip is set with the outer surface of gear to be concordant.
Compared with prior art, the beneficial effects of the invention are as follows：The present invention can effectively weaken vibrations by annular groove,
Vibrations can be transmitted on rubber strip and be eliminated simultaneously, while stress elimination hole can eliminate internal stress, so as to reduce shake
It is dynamic, while rubber column can eliminate absorption vibrations, the setting of sealing ring can be when gear and rotating shaft coordinate to gear sheet
Body is preferably fixed, and reduces gap, so as to reduce vibrations, reaches the purpose of noise reduction.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention；
Fig. 2 is that A-A of the present invention cuts open structural representation；
Fig. 3 is mplifying structure schematic diagram at B of the present invention.
In figure：It is 1 gear, 2 centre bores, 3 necks, 4 annular grooves, 5 rubber strips, 6 stress elimination holes, 7 rubber columns, 8 recessed
Groove, 9 sealing rings.
Embodiment
