Preferably, the liquid outlet is the ipsilateral of inlet by the pipeline configuration of bending.
Preferably, the engaging portion of the pump housing and the rear cover is sealed by sealing ring.
Preferably, the diameter ratio of first reduction gearing and the second reduction gearing is 1 to 2.5.
Preferably, the herringbone driven gear is configured in the pump housing by pin shaft.
Preferably, the herringbone driving gear and herringbone driven gear include left-half helical gear and right half part
Helical gear, left-half helical gear and right half part helical gear, which fit together, to form the herringbone driving gear and herringbone is driven
Gear is equal.
Preferably, first reduction gearing, the second reduction gearing, motor base, the pump housing, herringbone driving gear, people
Word driven gear and rear cover are plastic material.
The utility model has the beneficial effects that
The miniature magnetic driving gear pump of the utility model can be widely used in small household appliances, so to cost control and processing
Simplification is high, and gear pump case and gear use the precise injection molding one-pass molding of PPS food grade plastic, has that the processing is simple, dress
With convenient feature；Mating DC brush micro machine forms gear pump assembly, guarantees wanting for the high torque slow-speed of revolution using gear ratio
It asks, using double helical spurgear, has gear pump axial load small, the characteristics of bearing capacity is big, stable working.
Detailed description of the invention
Fig. 1 is that the miniature magnetic of the utility model drives the structural schematic diagram of gear pump；
Fig. 2 is that the miniature magnetic of the utility model drives the decomposition texture schematic diagram of gear pump.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing, as depicted in figs. 1 and 2, a kind of miniature magnetic driving
Gear pump, including minisize dc brush motor 1, the first reduction gearing 2, the second reduction gearing 3, motor base 4, axle envelope 5, the pump housing
6, herringbone driving gear 7, herringbone driven gear 8 and rear cover 9；
The shaft of the minisize dc brush motor 1 connects first reduction gearing 2, first reduction gearing 2 with
Second reduction gearing 3 engages, and the diameter of first reduction gearing 2 is less than the diameter of second reduction gearing 3, specifically
The diameter ratio of ground, first reduction gearing 2 and the second reduction gearing 3 is 1 to 2.5；The motor base 4 is bathtub construction,
First reduction gearing 2 and the second reduction gearing 3 are closed in the motor base 4, and one end of the motor base 4 passes through
The pump housing closing, the shaft 10 of second reduction gearing 3 are extend into the pump housing 6 by the axle envelope 5, and axle envelope 5
In in the motor base 4；The pump housing 6 is similarly bathtub construction, and the herringbone driving gear 7 and herringbone driven gear 8 are logical
It crosses the pump housing 6 and rear cover 9 is closely configured in the pump housing 6, the herringbone driving gear 7, which is configured at, is deep into the pump
In the shaft 10 of second reduction gearing in body 6, the herringbone driven gear 8 passes through pin shaft 11 and the herringbone driving tooth
7 engagement of wheel, inlet 12 and liquid outlet 13 are located at the pump of 8 engagement place two sides of the herringbone driving gear 7 and herringbone driven gear
On body, for convenience of connecting, the liquid outlet 13 is the ipsilateral of inlet 12 by the pipeline configuration of bending.6 He of the pump housing
The engaging portion of the rear cover 9 is sealed by sealing ring 14.
The herringbone driving gear 7 and herringbone driven gear 8 include left-half helical gear and right half part helical gear,
Left-half helical gear and right half part helical gear fit together to form the herringbone driving gear 7 and herringbone driven gear 8.
First reduction gearing 2, the second reduction gearing 3, motor base 4, the pump housing 6, herringbone driving gear 7,8 and of herringbone driven gear
Rear cover 9 is plastic material.Here herringbone bear is equivalent to that two helical angles are equal in magnitude, and the opposite helical gear of the hand of spiral is simultaneously
Get up to be driven, so that the axial force that both sides generate mutually balances counteracting.Because herringbone bear processing is relatively difficult, herringbone
Gear separately designs, and driving gear top is that left-hand helical gear lower part is dextrorotation helical gear, and driven gear top is dextrorotation helical teeth
Wheel lower part is left-hand helical gear, and combination installation after processing is completed forms herringbone bear.This side is installed in separately design, combination
It is relatively difficult not only to have solved herringbone bear processing, but also can reach the high performance effect of herringbone bear for formula；Simultaneously as pump is whole
Size Control is smaller, so DC brush micro machine can only be used.But the characteristics of this motor be high revolving speed, low torque,
It is not able to satisfy gear high torque slow-speed of revolution job requirement.It works under high revolving speed easily to each parts depreciation of gear pump, low torque
Operating pressure needed for being then unable to reach gear again.Using 2.5:1 reduction gearbox, 2.5 times of motor of revolving speed is reduced, is greatly improved
The torque of motor.
