Description
Technical field
It the utility model is related to a kind of pump shaft, more particularly to a kind of pump shaft with endoporus.
Background technology
The pump shaft of compact end sucking pump and the connected mode of motor shaft mainly have two kinds.One kind is that pump shaft processes endoporus,
Motor shaft head is inserted in by endoporus, moment of torsion is transmitted by key connection, another kind is by pump shaft and motor axis clamping by shaft coupling
Carry out special delivery moment of torsion.
The first in the prior art, if pump shaft axis hole and motor shaft are easier using gap cooperation, dismounting, but reliably
Property is bad.Pump easily produces shock and vibration in the process of running, influences service life, and cause noise pollution to environment；
If pump shaft axis hole and motor shaft use interference fits or interference fit, connection reliably, during operation is not likely to produce impact shock, but
Assembly difficulty is larger, and repair demolition difficulty is very big.
Second in the prior art, and pump shaft and motor shaft are realized into two halves join by screw to folder using two half a couplers
The clamping of axle device.Need to adjust each screw in this scheme tightens order and torque to ensure the coaxial of pump shaft and motor shaft
Degree.It is relatively time-consuming during assembling, and the processing technology of shaft coupling is complicated, cost is high.And product structure is complicated.
Utility model content
The purpose of this utility model is the defects of being directed to prior art, there is provided a kind of pump shaft, it is possible to achieve with motor shaft
Reliable connection, and can makes installation and removal very convenient.
To achieve the above object, the utility model provides a kind of pump shaft, and the pump shaft includes：
Pump shaft body, the pump shaft body has inner chamber, for housing external electrical arbor；
Endoporus, it is axially vertical with the pump shaft body in the outer wall of the inner chamber of the pump shaft body；
Elastic groove, on the outer wall of the inner chamber of the pump shaft body, the endoporus is divided into the first endoporus and second
Endoporus, the elastic groove are axially in parallel with the pump shaft body；
The external electrical arbor is placed in the interior intracavitary of the pump shaft body, the external electrical arbor top and the pump shaft
Support the inwall end of chamber body；Worn using screw and set into first endoporus and the second endoporus spiral shell, the elastic groove contracting
Enter, the pump shaft body is by the motor axis clamping.
Further, the elastic groove is more than one, and the endoporus is more than one.
Further, first endoporus is unthreaded hole, and second endoporus is screwed hole.
Therefore, pump shaft of the present utility model, realize and be reliably connected with motor shaft realization, and can makes installation and removal non-
It is often convenient.Product reliability is improved, shortens the Product Assembly time, so as to reduce time cost and financial cost.
Brief description of the drawings
Fig. 1 is the schematic diagram of the utility model pump shaft；
Fig. 2 is the sectional view of Figure 1B B lines；
Fig. 3 is the side view of the utility model pump shaft；
Fig. 4 is the stereogram of the utility model pump shaft.
Embodiment
Below by drawings and examples, the technical solution of the utility model is described in further detail.
Fig. 1 is the schematic diagram of the utility model pump shaft, and Fig. 2 is the sectional view of Figure 1B B lines, and Fig. 3 is the utility model pump shaft
Side view, Fig. 4 be the utility model pump shaft stereogram.
Referring to illustrated above, pump shaft of the present utility model includes：Pump shaft body 1, endoporus 2 and elastic groove 3.
Specifically, pump shaft body 1 has inner chamber 10, for housing external electrical arbor.
Endoporus 2 is located in the outer wall of the inner chamber 10 of pump shaft body, axially vertical with pump shaft body 1.
Elastic groove 3 is located on the outer wall of the inner chamber 10 of pump shaft body 1, and endoporus 2 is divided into the first endoporus 21 and second
Hole 22, elastic groove 3 are axially in parallel with pump shaft body 1；
Optionally, elastic groove 3 is more than one, and endoporus 2 is more than one；Elastic groove 3 and endoporus 2 be all in embodiment itself
It is two.Optional first endoporus 21 is unthreaded hole, and the second endoporus 22 is screwed hole.
When external electrical arbor is placed in the inner chamber 10 of pump shaft body 1, at the top of external electrical arbor with the inner chamber of pump shaft body 1
Support 10 inwall end；Worn using screw and set into the first endoporus 21 and the spiral shell of the second endoporus 22, elastic groove 3 is retracted, pump shaft sheet
Body 1 is by motor axis clamping.
During specific works, one end of pump shaft body 1 processes endoporus 2, for being coupled prime mover, such as the electricity of external motor
The spindle nose of arbor.Elastic groove 3 is processed at the both ends of endoporus 2, so when pump shaft is assembled into motor shaft, can be very easy to,
Significantly brief installation time and assembly difficulty.When being assembled to correct position, external motor spindle nose end contact to pump shaft endoporus
End face, complete axially position.The composition of endoporus is unthreaded hole and screwed hole.
When pump shaft body is on the motor shaft, after completing axially position, using screw using unthreaded hole and screwed hole by pump
Shaft body is clamped on motor shaft.It can so ensure that pump shaft is reliably tied with motor shaft.There is keyway in pump shaft endoporus,
Pump shaft transmits moment of torsion with motor shaft by key connection.
Therefore, pump shaft of the present utility model, realize and be reliably connected with motor shaft realization, and can makes installation and removal non-
It is often convenient.Product reliability is improved, shortens the Product Assembly time, so as to reduce time cost and financial cost.
It should be noted last that above example is only unrestricted to illustrate the technical solution of the utility model, to the greatest extent
The utility model is described in detail with reference to preferred embodiment for pipe, it will be understood by those within the art that, can be with
The technical solution of the utility model is modified or equivalent substitution, without departing from technical solutions of the utility model spirit and
Scope.
