Description
Technical field
This utility model belongs to field of mechanical technique, relates to a kind of deep well pump, particularly to a kind of deep well pump pump shaft.
Background technology
At present, the motor shaft in domestic deep well pump pump shaft and impeller axle are to realize split by the spline coordinated to connect
, this set has the pump shaft of spline in use to have the following disadvantages: on the one hand, owing to pump shaft upper spline starts
Place is provided with groove, thus in running, positioning groove is easily generated stress concentration, ultimately results in axle fracture；On the other hand, flower
Keyway arrangements is complicated, and processing time consuming is laborious, and Cutter wear is big, and manufacturing cost is high, and axiality is difficult to ensure that.
Summary of the invention
The purpose of this utility model is for the above-mentioned problems in the prior art, it is provided that a kind of intensity is high, rotates
Stable deep well pump pump shaft.
The purpose of this utility model can be realized by following technical proposal: a kind of deep well pump pump shaft, including motor shaft and
Impeller axle, it is characterised in that described motor shaft is followed successively by upper bearing (metal) linkage section, the upper location shaft shoulder, motor connection from top to bottom
Section, the lower location shaft shoulder and lower bearing linkage section, described impeller axle is fixed with one with the upper bearing (metal) linkage section on motor shaft, institute
The end of the impeller axle stated is provided with stopper slot, and the cross section of described impeller axle is regular hexagon, and described upper bearing (metal) connects
The diameter of section is more than the circumscribed diameter of impeller axle.
The hexagon impeller axle of this deep well pump pump shaft and motor shaft are integrally machined molding, the stopper slot of impeller axle upper end and upper
Multi-stage impeller can be limited on impeller axle by bearing linkage section, and upper bearing (metal) linkage section and lower bearing linkage section are respectively by upper location
Bearing is limited on its position by the shaft shoulder and the lower location shaft shoulder so that its structural strength is higher, rotates more stable.
In above-mentioned a kind of deep well pump pump shaft, the diameter of the described upper location shaft shoulder is straight more than upper bearing (metal) linkage section
Footpath, the diameter of the described upper location shaft shoulder is less than the diameter of motor linkage section.The setting of the upper location shaft shoulder of this dimensional standard is opened
Arrive the effect of spacing upper bearing (metal).
In above-mentioned a kind of deep well pump pump shaft, the diameter of the described lower location shaft shoulder is straight more than lower bearing linkage section
Footpath, the diameter of the described lower location shaft shoulder is less than the diameter of motor linkage section.The setting of the lower location shaft shoulder of this dimensional standard is opened
Arrive the effect of spacing lower bearing.
Compared with prior art, motor shaft and the impeller axle of this deep well pump pump shaft is formed in one so that it has intensity
Height, the advantage of slow-roll stabilization.
Accompanying drawing explanation
Fig. 1 is the perspective view of this deep well pump pump shaft.
In figure, 1, motor shaft；2, impeller axle；3, upper bearing (metal) linkage section；4, the upper location shaft shoulder；5, motor linkage section；6, under
The location shaft shoulder；7, lower bearing linkage section；8, stopper slot.
Detailed description of the invention
The following is specific embodiment of the utility model and combine accompanying drawing, the technical solution of the utility model is made further
Description, but this utility model is not limited to these embodiments.
As it is shown in figure 1, this deep well pump pump shaft includes motor shaft 1 and impeller axle 2, motor shaft 1 is followed successively by upper shaft from top to bottom
Hold linkage section 3, the upper location shaft shoulder 4, motor linkage section 5, the lower location shaft shoulder 6 and lower bearing linkage section 7, impeller axle 2 and motor shaft 1
On upper bearing (metal) linkage section 3 be fixed with one, the end of impeller axle 2 is provided with stopper slot 8, and the cross section of impeller axle 2 is positive six
Limit shape, the diameter of upper bearing (metal) linkage section 3 is more than the circumscribed diameter of impeller axle 2.
Describing in detail further, the diameter of the upper location shaft shoulder 4 in this deep well pump pump shaft is more than the diameter of upper bearing (metal) linkage section 3,
The diameter of the upper location shaft shoulder 4 is less than the diameter of motor linkage section 5, and the diameter of the lower location shaft shoulder 6 is straight more than lower bearing linkage section 7
Footpath, the diameter of the lower location shaft shoulder 6 is less than the diameter of motor linkage section 5.
Specific embodiment described herein is only to this utility model spirit explanation for example.This utility model institute
Belong to those skilled in the art described specific embodiment to make various amendment or supplement or use similar
Mode substitute, but without departing from spirit of the present utility model or surmount scope defined in appended claims.
Although the most more employing motor shaft 1, impeller axle 2, upper bearing (metal) linkage section 3, the upper location shaft shoulder 4, motor even
The terms such as the section of connecing 5, the lower location shaft shoulder 6, lower bearing linkage section 7, stopper slot 8, but it is not precluded from using the probability of other term.
Use these terms to be only used to more easily and describe and explain essence of the present utility model；It is construed as any one
Additional restriction is all contrary with this utility model spirit.
