Model utility content
For existing problem, the purpose of this utility model is to provide a kind of automobile engine cooling water pump improving the band belt pulley of the bearing long service life of bearing life.
To achieve these goals, the technical solution of the utility model is: a kind of automobile engine cooling water pump of band belt pulley of bearing long service life, 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, there is the belt drives portion of belt drives groove, described belt drives portion is sleeve-shaped, 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,
The inwall of the axial circular hole of described water pump body is provided with annular overflow trough, and described annular overflow trough is between bearing and water seal, and described water pump body is provided with spilling water through hole, and annular overflow trough is communicated with outward with water pump body by described spilling water through hole.
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.
At water pump body axial circular-hole internal-wall, annular overflow trough is set, annular overflow trough has blocked the road that water removes bearing, water flows to outside water pump body by spilling water through hole again, by the cooperation of annular overflow trough and spilling water through hole, than arranging spilling water through hole more can play the effect avoiding water to enter bearing separately, 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.Arrange annular overflow trough in spilling water through hole, thoroughly blocking-up is leaked and is entered bearing, improves the working life of bearing further.
