Abstract
The utility model discloses a novel fuel pump rotor comprising a rotor main shaft, a rotor winding, a rotor iron core and a gear wheel arranged on the rotor main shaft; the rotor iron core is provided with an oblique outer edge slot, the rotor winding is embedded in the outer edge slot of the rotor iron core, and an angle between the outer edge slot and the rotor main shaft is 4 degrees; one end of the outer edge slot is provided with an oil inlet, and the other end of the outer edge slot is provided with an oil outlet; the rotor main shaft and the gear wheel are arranged in one body; the rotor main shaft is provided with a protection layer; a protection layer is arranged outside the rotor winding, so the rotor can be formed to be a smooth cylinder; the outer edge slot in the technical scheme is arranged in the oblique slot so as to reduce rotation resistance force of the fuel pump rotor, the electric fuel pump is stable in rotation speed, and low in noise; the protection layer can reduce rotation resistance force of the fuel pump rotor, improves pump efficiency, and prolongs service life.
Description
Technical field
The utility model relates to fuel pump technical field, is specifically related to a kind of novel fuel pump rotor.
Background technology
Fuel pump rotor in known technology, comprises the rotor that is contained in rotating shaft and by the fixing gear of a keyboard.This gear is worked under long-term slow-speed of revolution high-torque environment, and easy generation detrusion built in a word, causes gear engagement displacement, makes the flank of tooth produce contact wear, causes the electric fuel punp life-span to reduce.Conventionally rotor turns round in fluid, and epitrochanterian straight-line groove is one of maximum resistance of rotor running, is also the major reason that reduces rotor operation efficiency.
Summary of the invention
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of reasonable in design, improve fuel pump useful life, reduce fuel pump rotor resistance, improves the novel fuel pump rotor of the efficiency of pump.
For achieving the above object, the utility model provides following technical scheme: a kind of novel fuel pump rotor, comprise rotor main shaft, rotor winding, rotor core and be arranged on the gear on rotor main shaft, on described rotor core, be provided with outer groove, the embedding of rotor winding is filled in the groove of the outer of rotor core, described outer groove is skewed slot, the angle of described outer groove and rotor main shaft is 4 °, and groove one end, outer is provided with fluid import, the outer groove other end is provided with fluid outlet, described fluid import and fluid outlet are truncated cone-shaped, described rotor main shaft and gear are wholely set, and on described rotor main shaft, be provided with one deck overcoat, described rotor winding is outside equipped with protective layer, described protective layer makes rotor form a smooth cylinder.
By adopting technique scheme, outer groove is arranged to reduce fuel pump rotor resistance after skewed slot, makes that electric fuel oil revolution speed is steady, noise is low; Rotor main shaft and gear are wholely set, and gear is fixing reliable, can not be shifted, and protective layer makes rotor form a smooth cylinder, reduce fuel pump rotor resistance, improve the efficiency of pump, have extended useful life.
The utility model is further set to: on described rotor core, be axially evenly provided with many outer grooves.By this setting, outer groove arranges rationally, and working rotor is more reliable.
The utility model is also further set to: described rotor core is overrided to form after by 0.3 thick silicon steel sheet punching press.By this setting, described rotor core arranges rationally, works more reliable.
The utility model is also further set to: described overcoat and protective layer are epoxy resin layer.By this setting, epoxy resin has high strength, makes rotor longer service life.
The utility model has the advantages that: compared with prior art, the setting of the utility model structure is more reasonable, outer groove is arranged to reduce fuel pump rotor resistance after skewed slot, makes that electric fuel oil revolution speed is steady, noise is low; Rotor main shaft and gear are wholely set, and gear is fixing reliable, can not be shifted, and protective layer makes rotor form a smooth cylinder, reduce fuel pump rotor resistance, improve the efficiency of pump, have extended useful life.
Below in conjunction with Figure of description and specific embodiment, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
Referring to Fig. 1, the disclosed a kind of novel fuel pump rotor of the utility model, comprise rotor main shaft 1, rotor winding 2, rotor core 3 and be arranged on the gear 4 on rotor main shaft 1, on described rotor core 3, be provided with outer groove 31, 2 embeddings of rotor winding are filled in the outer of rotor core 3 groove 31, described outer groove 31 is skewed slot, described outer groove 31 is 4 ° with the angle of rotor main shaft 1, be that the angle forming between the horizontal plane at axial line place of outer groove 31 inner surfaces and armature spindle 1 is 4 °, and groove 31 one end in outer are provided with fluid import 311, groove 31 other ends in outer are provided with fluid outlet 312, described fluid import 311 and fluid outlet 312 are truncated cone-shaped, described rotor main shaft 1 is wholely set with gear 4, and be provided with one deck overcoat 6 on described rotor main shaft 1, described rotor winding 2 is outside equipped with protective layer 7, described protective layer 7 makes rotor form a smooth cylinder.
For making the setting of the utility model structure more reasonable, as preferably, on the rotor core 3 described in the present embodiment, be axially evenly provided with many outer grooves 31.The quantity of outer groove 31 arranges according to actual needs.
Described rotor core 3 is overrided to form after by 0.3 thick silicon steel sheet punching press.Described overcoat 6 and protective layer 7 are epoxy resin layer.Epoxy resin layer has good adhesive strength and chemical-resistance.
The utility model structure arranges rationally, and outer groove is arranged to reduce fuel pump rotor resistance after skewed slot, makes that electric fuel oil revolution speed is steady, noise is low; Rotor main shaft and gear are wholely set, and gear is fixing reliable, can not be shifted, and protective layer makes rotor form a smooth cylinder, reduce fuel pump rotor resistance, improve the efficiency of pump, have extended useful life.
Above-described embodiment is to specific descriptions of the present utility model; only for the utility model is further described; can not be interpreted as the restriction to the utility model protection range, within the technician of this area makes some nonessential improvement according to the content of above-mentioned utility model to the utility model and adjusts and all to fall into protection range of the present utility model.
