Abstract
The utility model discloses a kind of associated mode water pump, including the pump housing being provided with impeller cavity and the motor being fixed together with the pump housing, it is provided with pump shaft in described impeller cavity, motor shaft couples with pump shaft and is provided with impeller on described pump shaft, described motor shaft is coaxial docking with pump shaft and is welded and fixed and is integrated, described motor shaft is provided with socket in butt end, and described pump shaft is provided with in butt end and the insertion section of socket hot pressing interference fit.The technical solution adopted in the utility model, motor shaft itself can use common material, and pump shaft uses special substance, it is possible to decrease production cost, and major part metal material all can so combine and make, and processing is simple.
Description
Technical field
This utility model relates to water pump.
Background technology
Associated mode water pump is that motor is coaxial with pump, pump shaft directly with motor shaft integrally, but, need special substance at pump shaft
Time, axle entirety is required for making special substance, and it has the disadvantage that to make special substance relatively costly, and the special material of part
Matter is not suitable for making motor shaft.
Utility model content
Technical problem to be solved in the utility model is just to provide a kind of associated mode water pump, and it is special to need to use at pump shaft
During material, cost can be reduced.
For solving above-mentioned technical problem, this utility model adopts the following technical scheme that a kind of associated mode water pump, including being provided with
The pump housing of impeller cavity and the motor being fixed together with the pump housing, be provided with pump shaft in described impeller cavity, motor shaft couple with pump shaft and
Being provided with impeller on described pump shaft, described motor shaft is coaxial docking with pump shaft and is welded and fixed and is integrated, and described motor shaft is right
Connecing end and be provided with socket, described pump shaft is provided with in butt end and the insertion section of socket hot pressing interference fit.
As preferably, described pump shaft is provided with the flange connected with insertion section, is formed between described flange and socket end face
Accommodate the V-ring groove of wlding.
As preferably, described socket is circular hole, and described insertion section is cylindrical.
As preferably, described motor shaft uses 45 steel to make, and described pump shaft uses steel alloy to make.
The technical solution adopted in the utility model, after pump shaft uses pressure sintering interference fit to be connected with motor shaft, welding adds
Work, motor shaft itself can use common material, and pump shaft uses special substance, it is possible to decrease production cost, and major part metal material
Matter all can so combine and make, and processing is simple.
Accompanying drawing explanation
With detailed description of the invention, this utility model is further described below in conjunction with the accompanying drawings:
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of axle.
Detailed description of the invention
As depicted in figs. 1 and 2, a kind of associated mode water pump, including being provided with the pump housing 1 of impeller cavity and being fixed on one with the pump housing 1
The motor 2 risen, motor bottom is provided with motor support base 22, is provided with pump shaft 11 in described impeller cavity, and motor shaft 21 couples with pump shaft 11
And impeller 12 is installed on pump shaft.
Wherein, described motor shaft 21 is coaxial docking with pump shaft 11 and is welded and fixed and is integrated.Therefore, motor shaft 21 itself can
To use common material, pump shaft 11 uses special substance, and to reduce production cost, specifically, described motor shaft 21 uses 45
Steel is made, and described pump shaft 11 uses steel alloy to make.
Further, described motor shaft is provided with socket 211 in butt end, and described pump shaft is provided with in butt end and socket hot pressing
The insertion section 111 of interference fit, specific to the present embodiment, socket is circular hole, and insertion section is cylindrical, is certainly not excluded for using square
The cooperation of shape, hexagon or other polymorphic structures.
Described pump shaft 11 is being provided with the flange 112 connected with insertion section 111, described flange and socket end away from side, insertion section
The V-ring groove accommodating wlding is formed between face.Forming first by hot pressing interference fit to reconnect, after welding, wlding is filled
In V-ring groove, make motor shaft 21 and pump shaft 11 form second and reconnect, ensure motor shaft 21 eventually through duplex connecting structure
With being reliably connected of pump shaft 11.
