Description
Technical field
Pump housing technical field is the utility model is related to, in particular to a kind of gear pump for clearing up load force.
Background technology
Gear pump is to convey liquid by the swept volume change and movement that are formed between pumping cylinder and meshing gear or make
Supercharging drum pump.Two enclosure spaces are formed by two gears, the pump housing and front and rear covers, when gear rotates, are out of gear
The volume in the space of side becomes larger from small, forms vacuum, draws liquid into, the volume in the space of gear engagement side from diminishing greatly, and
Liquid is squeezed into pipeline.
Gear pump is after a period of time is run, and the problem of oil leak between gear often occurs, annoyings the manufacture of gear pump
Business and user, and oil leak causes between gear often caused by the effect of pump inside and outside load force in the process of running
Cooperation go wrong, it is therefore desirable to consider gear pump load force resolution performance.
Utility model content

One mounting hole, is each provided with a pump case mounting screw at another diagonal, transmission shaft is additionally provided with the front pump cover
Mounting portion, be provided with around the transmission shaft mounting portion several circular load forces resolution grooves and be arranged at the same time it is described from
Auxiliary load force resolution groove above driving wheel.
As the preferred of above-mentioned technical proposal, the auxiliary load force resolution slot part envelopes a nearest load force
Clear up groove.
As the preferred of above-mentioned technical proposal, the pump case mounting screw is installed in the through hole of hexagon.
As the preferred of above-mentioned technical proposal, several card slots are provided with the front pump cover.
As the preferred of above-mentioned technical proposal, the transmission shaft mounting portion include the annular wall that raised annulus formed and
