Abstract
This utility model relates to the armature spindle fixing device of a kind of circulating pump, including housing, it is provided with armature spindle installing rack in housing, in armature spindle installing rack, armature spindle is installed, one end of armature spindle is arranged in armature spindle installing rack, and the other end of armature spindle is arranged on the pump housing；The pump housing is provided with armature spindle mounting post, is provided with armature spindle installing hole in armature spindle mounting post, and armature spindle installing hole is non-circular hole, and at least one end of armature spindle is provided with the milling flat matched with non-circular hole.This utility model makes the two ends of armature spindle be on-circular cross-section structure, effectively prevents armature spindle from producing rotation or axial float in the structure shown here due to the rotation of rotor；It is also provided with the armature spindle installing hole of the non-circular hole matched with armature spindle end in the pump housing and armature spindle connection place, effectively limits armature spindle and rotate or axial float.
Description
Technical field
This utility model relates to the armature spindle fixing device of a kind of circulating pump, one of parts belonging to circulating pump.
Background technology
The armature spindle of water circulating pump in the structure shown here, serves and supports rotor, ensures the work that rotor can the most reliably rotate
With, but, the most often there is the phenomenon such as axial float or rotation in armature spindle of the prior art, is unfavorable for
The stable operation that circulating pump is overall.It is therefore proposed that this utility model.
Utility model content
For the above-mentioned technical problem of prior art, the armature spindle that the purpose of this utility model is to provide a kind of circulating pump is solid
Determine device, its axial float being prevented from armature spindle or rotation, substantially increase the stability of circulating pump mass motion.
For reaching above-mentioned purpose, this utility model is achieved through the following technical solutions:
The armature spindle fixing device of a kind of circulating pump, including housing, is provided with armature spindle installing rack, armature spindle in housing
Being provided with armature spindle in installing rack, one end of armature spindle is arranged in armature spindle installing rack, and the other end of armature spindle is arranged on pump
On body；The pump housing is provided with armature spindle mounting post, is provided with armature spindle installing hole in armature spindle mounting post, and armature spindle installing hole is not rounded
Shape hole, at least one end of armature spindle is provided with the milling flat matched with non-circular hole.
The two ends of described armature spindle are equipped with the milling flat matched with non-circular hole.
On described armature spindle, rotor is installed.
The armature spindle fixing device of this utility model circulating pump has the advantages that
1, the two ends of armature spindle arrange milling flat so that the two ends of armature spindle are on-circular cross-section structure, effectively prevent rotor
Axle produces rotation or axial float in the structure shown here due to the rotation of rotor；
2, the armature spindle peace of the non-circular hole matched with armature spindle end it is also provided with in the pump housing and armature spindle connection place
Dress hole, effectively limits armature spindle and rotates or axial float.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of the pump housing in this utility model；
Fig. 3 is the structural representation of the armature spindle in this utility model；
Wherein, 1 it is housing, 2 is armature spindle installing rack, 3 is armature spindle, 4 is the pump housing, 5 is armature spindle mounting post, 6 is
Armature spindle installing hole, 7 be rotor, 8 for milling flat.
Detailed description of the invention
Below in conjunction with specific embodiment, this utility model is further described, but protection domain of the present utility model is also
It is not limited to this.
As Figure 1-3, the armature spindle fixing device of this utility model circulating pump, including housing 1, set in housing 1
There is armature spindle installing rack 2, armature spindle 3 is installed in armature spindle installing rack 2, armature spindle 3 is provided with rotor 7.The one of armature spindle 3
End is arranged in armature spindle installing rack 2, and the other end of armature spindle 3 is arranged on the pump housing 4；The pump housing 4 is provided with armature spindle mounting post
5, it is provided with armature spindle installing hole 6 in armature spindle mounting post 5, armature spindle installing hole 6 is non-circular hole, at least one of armature spindle 3
End is provided with the milling flat 8 matched with non-circular hole.
For increasing the compatibility of armature spindle 3, the two ends of the armature spindle 3 in this utility model are equipped with and non-circular hole phase
The milling flat 8 joined.
This utility model makes the two ends of armature spindle 3 be on-circular cross-section structure, effectively prevent armature spindle 3 in the structure shown here by
Rotation or axial float is produced in the rotation of rotor 7；It is also provided with and armature spindle 3 end in the pump housing 4 and armature spindle 3 connection place
The armature spindle installing hole 6 of the non-circular hole matched, effectively limits armature spindle 3 and rotates or axial float.
Above-described embodiment is only used for illustrating inventive concept of the present utility model, rather than to this utility model rights protection
Restriction, all changes utilizing this design that this utility model carries out unsubstantiality, protection model of the present utility model all should be fallen into
Enclose.
