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, relate in particular to a kind of auto pump.
Background technique
Fig. 1 is prior art auto pump cross-sectional view, and as shown in Figure 1, at present, auto pump is mainly comprised of shaft connecting bearing 1, belt pulley 2, housing 4, water seal 5 and impeller 6.Wherein, housing 4 is provided with a through hole that runs through it, is referred to as housing endoporus, and shaft connecting bearing 1 is connected with housing 4 through the mode with interference fit after housing endoporus, and belt pulley 2 and impeller 6 are assemblied in respectively the two ends of shaft connecting bearing 1.Described shaft connecting bearing 1 plays rotary support effect and bears the thrust load from impeller 6 and belt pulley 2, and the driving torque of belt pulley 2 is transferred to impeller 6, and then impeller 6 drives cooling liquid rotation acting, and water seal 5 is used for sealing cooling liquid as Sealing.
Yet auto pump shaft connecting bearing 1 occurs abnormal or while being subject to some burst External Force Acting at work loads, the axial force that easily causes its generation is excessive and make shaft connecting bearing 1 that play occur in housing endoporus even to deviate from, thereby causes serious potential safety hazard.
Summary of the invention
The object of the invention is to solve the defect of above-mentioned prior art, provide a kind of shaft connecting bearing that can not make that the automobile engine cooling water pump that play is even deviate from occurs easily from housing endoporus.
A kind of auto pump; comprise housing, through the shaft connecting bearing of the housing endoporus of described housing; at the two ends of described shaft connecting bearing, be respectively fitted with belt pulley and impeller; water seal is also installed between impeller and housing; on the hole wall of housing endoporus, be provided with the first circular groove; on shaft connecting bearing, be provided with the second circular groove; the corresponding formation of the aperture position annular pass of described the first circular groove and the second circular groove is filled with by the bonding epoxy glue of structure and the mixing cured rear stop ring forming of small metal particles in described annular pass.
Further, on housing, be drilled with for pouring into the hole for injecting glue of the bonding epoxy glue of described structure and small metal particles.
Auto pump provided by the invention, by stop ring being set between housing endoporus and shaft connecting bearing, realized closely cooperating of shaft connecting bearing and housing, avoided shaft connecting bearing that the phenomenon that play is even deviate from occurs in housing endoporus, improved the safety reliability of auto pump, and simple in structure, good manufacturability.

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, the technological scheme in the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiments.Embodiment based in the present invention, those of ordinary skills, not making the every other embodiment who obtains under creative work prerequisite, belong to the scope of protection of the invention.
Fig. 2 is auto pump cross-sectional view of the present invention, as shown in Figure 2, housing 4 inside are provided with a housing endoporus, in housing endoporus, be penetrated with a shaft connecting bearing 1, described shaft connecting bearing 1 is connected with housing 4 by the mode of interference fit, at the two ends of shaft connecting bearing 1, be respectively fitted with belt pulley 2 and impeller 6, between impeller 6 and housing 4, be also provided with for sealing the Sealing of cooling liquid, i.e. water seal 5.In order effectively to prevent auto pump shaft connecting bearing 1, from housing endoporus, deviate from, the present invention is provided with a stop ring 3 on housing 4 and shaft connecting bearing 1, the concrete set-up mode of described stop ring 3 is: first, on the hole wall of housing endoporus, process a circular groove, this circular groove is called the first circular groove, at a circular groove of shaft connecting bearing 1 processing, this circular groove is called the second circular groove, annular pass of the corresponding formation of aperture position of described the first circular groove and the second circular groove, on housing 4, bore a hole for injecting glue simultaneously, this hole for injecting glue is led in described annular pass, then the bonding epoxy glue of interstitital texture and small metal particles in this annular pass, after it solidifies, form a higher stop ring of intensity and bear axial shearing force, thereby prevent that shaft connecting bearing from deviating from.
Finally it should be noted that: above embodiment only, in order to technological scheme of the present invention to be described, is not intended to limit; Although the present invention is had been described in detail with reference to previous embodiment, those of ordinary skill in the art is to be understood that: its technological scheme that still can record aforementioned each embodiment is modified, or part technical characteristics is wherein equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution depart from the spirit and scope of various embodiments of the present invention technological scheme.
