Description
Technical field
The utility model relates to a kind of engine water pump with belt pulley.
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.
Model utility content
For existing problem, the purpose of this utility model is to provide a kind of engine water pump improving the band belt pulley of bearing life.
To achieve these goals, the technical solution of the utility model is: a kind of engine water pump with belt pulley, 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 the axle head of water pump spindle, belt pulley is installed, 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.
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.
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.
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.
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: the engine water pump of band belt pulley 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, impellers 6.
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.
More than describe preferred embodiment of the present utility model in detail.Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to design of the present utility model without the need to creative work.Therefore, all technician in the art according to design of the present utility model on the basis of existing technology by the available technological scheme of logical analysis, reasoning, or a limited experiment, all should by the determined protection domain of claims.
