Description
Technical field
The utility model relates to a kind of automobile engine cooling water pump.
Background technique
Current automobile power (motor) water pump, as shown in Figure 1, comprise water pump body (1), water seal (2) and bearing (3) are arranged in water pump body (1) each section of axial circular hole respectively, water pump spindle (4) through bearing (3) and water seal (2) center hole, and installs belt pulley and impeller (6) respectively at two axle heads of water pump spindle (4).
As shown in Figure 1, be arranged on the axle head of water pump spindle 4 near the end of water pump body 1, belt pulley is arranged on water pump spindle by mounting flange 7 existing belt pulley, and the center line a of such belt drives groove and the center line b of bearing is not on the same line.That is, the active force that belt acts on belt drives groove center not in bearing in the heart, make the bending load that bearing is also subject to along force direction in water pump spindle rotary course, thus accelerate bearing wear.
In addition, although be provided with water seal 2, in vehicle traveling process, usually there will be the phenomenon that water seal is leaked, bearing end is High Rotation Speed when touching water, and the short time just there will be abnormal sound, destruction.
Model utility content
For existing problem, the purpose of this utility model is to provide a kind of automobile engine cooling water pump improving bearing life.
To achieve these goals, the technical solution of the utility model is: a kind of automobile engine cooling water pump, comprise water pump body, water seal and bearing are arranged in described water pump body each section of axial circular hole respectively, water pump spindle passes the center hole of bearing and water seal, and at two axle heads of water pump spindle, belt pulley and impeller are installed respectively, it is characterized in that: described belt pulley comprises the department of assembly with axis hole, the belt drives portion with belt drives groove, described belt drives portion is sleeve-shaped, and the end in described belt drives portion is connected with the end of department of assembly by support and connection portion; Described belt pulley is arranged on the axle head of water pump spindle by department of assembly, and described belt drives portion is enclosed within outside water pump body, has distance between described belt drives portion and water pump body, and the center line of described belt drives groove and the center line of bearing are on the same line;
Described water pump body is provided with spilling water through hole near water seal, and described spilling water through hole is between water seal and bearing, and the inwall of the axial circular hole of the water pump body between described spilling water through hole and bearing is pressed with water holding ring.
Adopting such scheme, by improving the structure of belt pulley, making the center line of the center line of belt drives groove and bearing on the same line.That is, belt acts on the center of the active force of belt drives groove on the bearing centre of water pump, makes water pump bearing can not be subject to bending load when water pump spindle rotates, and improves the working life of bearing.
Arrange spilling water through hole, the water spilt from water seal is flow to water pump body by this spilling water through hole, but spilling water through hole cannot stop water to enter bearing completely, therefore, between spilling water through hole and bearing, press-fit water holding ring again, the water flowed through blocks by water holding ring, avoids water to enter bearing.Returned again by the water stopped, flow out from spilling water through hole.Water can be avoided to enter bearing, improve the working life of bearing.
In such scheme: described belt pulley is fitted on water pump spindle.
In such scheme: described belt drives groove is provided with the gear teeth.
In such scheme: described spilling water through hole is two.Be conducive to outflow of leaking.
In such scheme: the groove width of described annular overflow trough is greater than the aperture of spilling water through hole.The groove width of annular overflow trough is large, is conducive to water like this and enters.
The beneficial effects of the utility model are: the utility model is by the adjustment to the structure of belt pulley, make the center line of the center line of belt drives groove and water pump bearing on the same line, like this, act on active force on belt drives groove in water pump bearing in the heart, make water pump bearing can not be subject to bending load when rotation, improve the working life of bearing.By arranging spilling water through hole and water holding ring, under the mating reaction of water holding ring and spilling water through hole, thoroughly avoiding water to enter in bearing, improving the working life of bearing.
Accompanying drawing illustrates:
Fig. 1 is the structural representation before improving.
Fig. 2 is structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further described:
Wait the position of the noun of locality only in representative graph up and down in the utility model, do not represent the absolute position of product.
Embodiment 1
As shown in Figure 2: automobile engine cooling water pump of the present utility model is made up of parts such as water pump body 1, water seal 2, bearing 3, water pump spindle 4, belt pulley 5, impeller 6, water holding ring 7, spilling water through holes 8.
Water pump body 1 is prior art, does not repeat at this.Water seal 2 and bearing 3 are arranged in water pump body 1 each section of axial circular hole respectively, water pump spindle 4 passes the center hole of bearing 3 and water seal 2, and at two axle heads of water pump spindle 4, belt pulley 5 and impeller 6 are installed respectively, belt pulley 5 comprises the department of assembly 51 with axis hole, the belt drives portion 52 with belt drives groove 55, belt drives portion 52 is in sleeve-shaped, belt drives groove 55 is positioned on the outer circumferential face in belt drives portion 52, and belt drives groove 55 is provided with the gear teeth 53.The end in belt drives portion 52 is connected with the end of department of assembly 51 by support and connection portion 54, belt drives portion 52, support and connection portion 54 and department of assembly 51 form tubbiness, and the medial axis in the medial axis (being also the medial axis of axis hole) of department of assembly 51 and belt drives portion 52 and support and connection portion 54 on the same line.The department of assembly 51 of belt pulley 5 is fitted on water pump spindle 4.Belt drives portion 52 is enclosed within outside water pump body 1, has distance between belt drives portion 52 and water pump body 1, and the center line a of belt drives the groove 55 and center line b of bearing 3 on the same line.Thus make belt drives groove 55 stressed in bearing 3 in the heart, avoid the bending load that bearing 3 is subject to.
Water pump body 1 is provided with spilling water through hole 8 near water seal 2, spilling water through hole 8 communicates with the axial circular hole of water pump body 1, spilling water through hole 8 is between water seal 2 and bearing 3, preferred radial spilling water through hole 8 is two, the aperture of two spilling water through holes 8, substantially circumferentially same, can certainly be multiple spilling water through hole 8.The inwall of the axial circular hole of the water pump body 1 between spilling water through hole 8 and bearing 3 is pressed with water holding ring 7.Water holding ring 7 thoroughly blocks the road that current remove bearing 3, and meanwhile, under the effect of water holding ring 7, the water flowing through spilling water through hole 8 is back to spilling water through hole 8 again, thus flows out outside water pump body 1.
