Size reduces material cost.
The assembling of split bush and tapered sleeve first penetrates pump shaft and rotor axis of electric in open conical sleeve in assembling, so
Afterwards one end of pump shaft slowly seal in tapered sleeve, tapered sleeve is pressed into open conical sleeve using press machine or hammer, until
Until automatically lock, principle is, after external tapered sleeve enters open conical sleeve outer circle, since tapered sleeve is stepped into from the microcephaly of tapered sleeve
The major part of tapered sleeve closes its open slot slowly under the action of taper power, turns it tightly pump shaft joined together by locking and
The sub- diameter of axle forms an entirety, realizes that the Quick fastening between axis and axis connects.
When solving group holding water pump, the relatively difficult problem of the centering of pump shaft and rotor axis of electric.It is practical this has been reached
Novel purpose.
Compared with prior art, the utility model patent has the advantage that
1, the armature spindle of its pump shaft and motor tightly locked solid is made by the automatically lock of tapered sleeve self-locking connecting device
It is fixed, change and pump shaft and rotor axis of electric connected by shaft coupling in the past, while reduce pump shaft and rotor axis of electric end with
Shaft coupling keyseat process and shaft coupling axially fasten screw, reduce the centering process during shaft coupling installation, reduce
Labor intensity improves production efficiency；
2, by the secondary operation after the self-locking connecting shaft device clamp device of tapered sleeve and its self-locking fastening, make its open conical sleeve
Water pump shaft end by the cooperation of bearing inner circle, guarantee that the outside diameter of bearing rib increases, reduce the size of the entire water pump diameter of axle,
Reduce the material consumption of pump shaft；
3, by the convex-concave slot rolled to above and below stretcher casing and its middle part, case strength and rigidity are improved, simultaneously
Also enhance the aesthetics of casing.
4, by the way that bearing block and its bearing cover, water inlet joint uses stainless steel material, improves the shape of submersible motor
Beauty does not pollute water quality and its to conveying chemical liquid with corrosion resistant effect because the casting of the pig iron corrodes.
