Abstract
The utility model discloses a rotating structure used for an automobile water pump. The rotating structure used for the automobile water pump comprises a cavity (1) and a shaft connection bearing (2), and the cavity (1) is in interference fit with the shaft connection bearing (2). A plurality of ring-shaped grooves (3) are arranged on the shaft connection bearing (2), and the upper portion of the cavity (1) is provided with a rivet rolling edge (4). The rivet rolling edge (4) is pressed on the shaft connection bearing (2), and the rivet rolling edge (4) is in a ring shape. The width of the rivet rolling edge (4) is one-tenth to one-fifth of the diameter of the rivet rolling edge (4). The structure is utilized in the rotating structure used for the automobile water pump, radial and axial clearances can be prevented from taking place in the shaft connection bearing of the automobile water pump, and therefore the normal working of the water pump is guaranteed.
Description
Technical field
The utility model relates to the auto pump field, specifically is used for the rotational structure of auto pump.
Background technique
Motor car engine extensively adopts Centrifugal water pump, and its basic structure is made of parts such as water pump cover, land or belt pulley, water pump spindle and bearing or shaft connecting bearing, water pump vane and water seal arrangements.Motor drives water pump bearing and wheel rotation by belt pulley, and the cooling liquid in the water pump is driven together rotation by impeller, is thrown toward the edge of water pump cover under the effect of centrifugal force, produces simultaneously certain pressure, then flows out from water outlet or water pipe.The reciprocation cycle of cooling liquid is realized because cooling liquid is thrown out of and pressure decreased, and the cooling liquid in the water tank is inhaled in the impeller through water pipe in the center of impeller under the differential pressure action at unit fixed on water pump suction and impeller center.
The rotational structure of auto pump mainly comprises shaft connecting bearing; shaft connecting bearing is fixed in the pump chamber by interference fit; in the working procedure of water pump, usually can occur because additional axial force or the unbalance shaft connecting bearing that causes occur axially or radial-play, and then cause water pump to lose efficacy.
The model utility content
The utility model provides the rotational structure that is used for auto pump, and having solved in the past, the problem that causes water pump to lose efficacy occurs axially or radial-play the shaft connecting bearing of water pump easily.
The utility model is that the technical solution problem is achieved through the following technical solutions: the rotational structure that is used for auto pump, comprise cavity and shaft connecting bearing, cavity and shaft connecting bearing interference fit, described shaft connecting bearing is provided with the groove of some ring-types, the top of described cavity is provided with the roll riveting limit, and described roll riveting limit is pressed on the shaft connecting bearing.
The groove of shaft connecting bearing can be fixed on shaft connecting bearing in the cavity better, prevents cavity generation axial float, simultaneously, shaft connecting bearing is pushed down on the roll riveting limit, play the effect of chucking, prevented that shaft connecting bearing breaks away from cavity, further avoided shaft connecting bearing to occur axially or radial-play.
Being shaped as of described roll riveting limit is circular, the width on roll riveting limit be the roll riveting limit diameter length 1/10 ~ 1/5.
Being shaped as of described roll riveting limit is circular-arc, and the top of cavity is provided with 4 roll riveting limits, and the length on roll riveting limit is 1/12 ~ 1/8 of place, roll riveting limit circumference.
Described groove equidistantly is distributed on the shaft connecting bearing, and the plane at groove place is vertical with the central shaft of shaft connecting bearing.
The degree of depth of described groove be groove place circumference diameter length 1/20 ~ 1/10.
The utility model compared with prior art has the following advantages and beneficial effect:
(1) shaft connecting bearing of the present utility model and cavity by at shaft connecting bearing groove being set, so that shaft connecting bearing is fixed in the cavity better, prevent that shaft connecting bearing from axial play occuring in rotation process on the basis of realizing interference fit.
(2) the utility model is stuck in shaft connecting bearing in the cavity firmly by the roll riveting limit is set at cavity, has avoided shaft connecting bearing to make the disengaging cavity in motion, prevents that shaft connecting bearing from occurring axially or the problem of radial-play, guarantees the normal operation of water pump.
Description of drawings
Fig. 1 is plan view of the present utility model.
The name that reference character is corresponding is called: 1, cavity, 2, shaft connecting bearing, 3, groove, 4, the roll riveting limit.
Embodiment
The utility model is described in further detail below in conjunction with embodiment, but mode of execution of the present utility model is not limited to this.
Embodiment 1:
As shown in Figure 1, present embodiment comprises cavity 1 and shaft connecting bearing 2, cavity 1 and shaft connecting bearing 2 interference fit, and shaft connecting bearing 2 is provided with the groove 3 of some ring-types, and the top of cavity 1 is provided with roll riveting limit 4, and roll riveting limit 4 is pressed on the shaft connecting bearing 2.
Being shaped as of the roll riveting limit 4 of present embodiment is circular, roll riveting limit 4 is stuck in the cavity 1, simultaneously shaft connecting bearing 2 shaft connecting bearing 2 whole parcel one circles firmly, with the width design on roll riveting limit 4 be roll riveting limit 4 diameter length 1/10 ~ 1/5, make roll riveting limit 4 block better shaft connecting bearing 2.
The groove 3 of present embodiment equidistantly is distributed on the shaft connecting bearing 2, and the plane at groove 3 places is vertical with the central shaft of shaft connecting bearing 2.
The degree of depth of the groove 3 of present embodiment be groove 3 place circumference diameter length 1/20 ~ 1/10.
Embodiment 2:
Present embodiment is substantially the same manner as Example 1, different places are, being shaped as of roll riveting limit 4 is circular-arc, the top of cavity 1 is provided with 4 roll riveting limits 4, and the length on roll riveting limit 4 is 1/12 ~ 1/8 of roll riveting limit 4 place circumference, roll riveting limit 4 is stuck in shaft connecting bearing 2 in the cavity 1 firmly, prevents that shaft connecting bearing 2 from play occuring.
Working principle of the present utility model is: shaft connecting bearing 2 is fixed in the cavity 1 by interference fit, then install roll riveting limit 4 additional at cavity 1, shaft connecting bearing 2 is stuck in the cavity 1 firmly, like this, auto pump is in work, shaft connecting bearing 2 just can not occur axially or play radially, and the assurance water pump is worked normally.
As mentioned above, then can realize well the utility model.
