Abstract
The invention provides an automobile water pump, which comprises a shell and a shaft connecting bearing passing through the shell inner hole of the shell, wherein a belt wheel and an impeller are assembled at the two ends of the shaft connecting bearing; a water seal is further arranged between the impeller and the shell; a first annular groove is formed in the shell inner hole; a second annular groove is formed in the shaft connecting bearing; open positions of the first annular groove and the second annular groove correspondingly form an annular channel; the annular channel is filled with a stop ring formed by mixing and curing structural bonding epoxy glue and small metal particles. According to the automobile water pump provided by the invention, the stop ring is arranged between the shell inner hole and the shaft connecting bearing, so that the shaft connecting bearing is firmly matched with the shell, the phenomena of play and even separation of the shaft connecting bearing in the shell inner hole are avoided, and the safety and reliability of the automobile water pump are improved. The automobile water pump is simple in structure, and has high manufacturability.
Description
Technical field
The present invention relates to car engine cooling system, more particularly, to a kind of auto pump.
Background technology
Fig. 1 is prior art auto pump cross-sectional view, as shown in figure 1, at present, auto pump is mainly by axle even
Bearing 1, belt pulley 2, housing 4, water seal 5 and impeller 6 form.Wherein, housing 4 is provided with a through hole running through it, referred to as
Shell inner hole, shaft connecting bearing 1 is connected with housing 4 after passing through shell inner hole in an interference fit, and belt pulley 2 and impeller 6
It is respectively assembled at the two ends of shaft connecting bearing 1.Described shaft connecting bearing 1 plays rotation supporting role and bears from impeller 6 and belt
The axial load of wheel 2, the driving torque of belt pulley 2 is transferred to impeller 6, and then impeller 6 drives coolant rotation acting, water seal 5
It is used for sealing coolant as sealing member.
However, auto pump shaft connecting bearing 1, when service load occurs extremely or is subject to some burst external force effects, holds
The axial force being easily caused its generation is excessive and make shaft connecting bearing 1 occur play even to deviate from shell inner hole, thus causing sternly
The potential safety hazard of weight.
Content of the invention
It is an object of the invention to solving the defect of above-mentioned prior art, provide one kind will not make shaft connecting bearing in housing
There is the play even automobile engine cooling water pump of abjection easily in hole.
A kind of auto pump, including the shaft connecting bearing of housing, the shell inner hole passing through described housing, in described shaft connecting bearing
Two ends be respectively fitted with belt pulley and impeller, be also equipped with water seal between impeller and housing, the hole wall of shell inner hole set
It is equipped with first annular groove, shaft connecting bearing is provided with the second cannelure, the opening position of described first annular groove and the second cannelure
Put corresponding formation circular passage, be filled with solid by structural bond epoxy glue and small metal particles mixing in described circular passage
The locating snap ring being formed after change.
Further, housing is drilled with the hole for injecting glue for irrigating described structural bond epoxy glue and small metal particles.
The auto pump that the present invention provides, by setting locating snap ring between shell inner hole and shaft connecting bearing it is achieved that axle
Connecting shaft holds the tight fit with housing, it is to avoid shaft connecting bearing occurs the play even phenomenon of abjection in shell inner hole, improves
The security reliability of auto pump, and structure is simple, good manufacturability.

Specific embodiment
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with the accompanying drawing in the present invention, to this
Technical scheme in invention is clearly and completely described it is clear that described embodiment a part of embodiment that is the present invention,
Rather than whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art are not making creative labor
The every other embodiment being obtained under the premise of dynamic, broadly falls into the scope of protection of the invention.
Fig. 2 is auto pump cross-sectional view of the present invention, as shown in Fig. 2 being provided with inside housing 4 in a housing
Hole, running through in shell inner hole has a shaft connecting bearing 1, and described shaft connecting bearing 1 is connected with housing 4 by way of interference fit
Connect, be respectively fitted with belt pulley 2 and impeller 6 at the two ends of shaft connecting bearing 1, be also equipped with for close between impeller 6 and housing 4
The sealing member of envelope coolant, i.e. water seal 5.In order to be able to effectively prevent auto pump shaft connecting bearing 1 from deviating from from shell inner hole, this
Bright be provided with a locating snap ring 3 on housing 4 with shaft connecting bearing 1, the concrete set-up mode of described locating snap ring 3 is：First, in shell
Process a cannelure on the hole wall in internal hole, this cannelure is referred to as first annular groove, process an annular in shaft connecting bearing 1
Groove, this cannelure is referred to as the second cannelure, and described first annular groove is corresponding with the aperture position of the second cannelure to form one
Circular passage, bores a hole for injecting glue, this hole for injecting glue is led in described circular passage on housing 4 simultaneously, then leads in this annular
Interstitital texture bonding epoxy glue and small metal particles in road, form a higher locating snap ring of intensity to bear axle after its solidification
To shearing force, thus preventing shaft connecting bearing from deviating from.
Finally it should be noted that：Above example only in order to technical scheme to be described, is not intended to limit；Although
With reference to the foregoing embodiments the present invention is described in detail, it will be understood by those within the art that：It still may be used
To modify to the technical scheme described in foregoing embodiments, or equivalent is carried out to wherein some technical characteristics；
And these modification or replace, do not make appropriate technical solution essence depart from various embodiments of the present invention technical scheme spirit and
Scope.
