Groove reversely intersects, bent above to form overhead structure to this spiral grooves of a sidewall of every described spiral grooves, and
Described overhead structure is partly suspended from this spiral grooves；Described plastic gear is formed at described power transmission shaft by Shooting Technique
Right part, two described spiral grooves are correspondingly arranged with described plastic gear, and are formed on described plastic gear and are filled in institute
State the spiral bar in spiral grooves, to increase the adhesive force of described plastic gear and described power transmission shaft, the right side of described plastic gear
End face is positioned at the left side of described power transmission shaft right side；It is provided with tubular gear chamber in described pump case, is provided with in described gear chamber
Axle sleeve, sleeve and spacer pin, the right part of described power transmission shaft coordinates with described axle sleeve, the left part of described power transmission shaft and described sleeve
Coordinating and described power transmission shaft is through described sleeve, the left end of described power transmission shaft is positioned at the outside of described pump case, described plastic gear
It is positioned at described gear chamber and described plastic gear is provided with the annular groove being slidably matched with described spacer pin, described to limit
Gear shaft displacement in the lateral direction, described annular groove is caved inward by the periphery of described plastic gear and forms.
Further, the periphery of the left end of described power transmission shaft is provided with plane, is formed flat with the left end at described power transmission shaft
Axle construction.
Further, described pump case is provided with mounting ear, with through hole on described mounting ear.
In this utility model, pump shell structure is simple, realizes the axial limiting to gear shaft by spacer pin, easy to assembly；Mould
Material gear be formed on power transmission shaft by Shooting Technique, and be provided with on power transmission shaft the spiral grooves corresponding with plastic gear and
Overhead structure, is provided with spiral grooves and makes plastic gear the most firm with the combination of power transmission shaft, arrange overhead structure and reduce further
The probability that plastic gear comes off, the processing of spiral grooves and overhead structure is very simple, utilizes spiral grooves and barb knot
Structure fixes plastic gear, it is easy to accomplish, alleviate the weight of gear shaft, and have that working (machining) efficiency is high and processing cost is low
Feature.
