Description
Technical field
The present invention relates to gear technique field, more particularly to a kind of automobile engine hydraulic pump wear-resistant 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 is occurred in that very early.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.
Hydraulic pump is that the gear in the important component in automobile engine, hydraulic pump plays gearing, but gear is carried out effective
Wear-resistant protection be it is very necessary, how cause gear preferably it is wear-resisting be we need in face of the problem of.
The content of the invention
The invention aims to solve shortcoming present in prior art, and a kind of automobile engine hydraulic pressure proposed
Pump wear-resistant gear.
To achieve these goals, present invention employs following technical scheme：
A kind of automobile engine hydraulic pump wear-resistant gear, including gear, the gear center are provided with centre bore, institute
Centre bore side is stated provided with neck, the gear edge is provided with arc back-up ring, the arc back-up ring is provided with fuel feed hole,
The gear between cog is provided with oil outlet, and flowline is communicated between the fuel feed hole and oil outlet.
It is preferred that, it is located in the gear on the outside of centre bore and is provided with lightening hole, and lightening hole is on the centre bore center of circle
For annular array.
It is preferred that, the number of the arc back-up ring is two, and is symmetrically distributed in gear positive and negative.
It is preferred that, the teeth in the gear pass through Carburization Treatment.
It is preferred that, the neck inwall, which is provided with clamping in groove, the groove, block rubber.
It is preferred that, the block rubber outer wall protrudes from groove inner wall.
It is preferred that, the arc back-up ring is set with centre bore for concentric circles.
Compared with prior art, the beneficial effects of the invention are as follows：The present invention, can be in gear by the setting of arc back-up ring
During rotation so that lubricating oil stopped by convolution, can cause lubricating oil via fuel feed hole by flowline so as to by oil outlet
The between cog of gear is entered, the between cog of gear is constantly lubricated, while the block rubber on neck inwall can
To reach more preferable snap action after fixing between gear and rotating shaft, reduce gear and rock so that gear sheet
Body is rotated and more smoothed out, so as to reach more preferable abrasion resistant effect.
