Description

Technical Field

[0001] This utility model relates to a water pump flange, specifically a water pump triangular flange. Background Technology

[0002] Water pump flanges are typically round flanges. Round flanges have a larger area, require more material, and are therefore relatively more expensive. While reducing the thickness of round flanges can lower costs to some extent, it will reduce the flange's strength and affect its performance. Utility Model Content

[0003] To address the shortcomings of the prior art, this utility model provides a triangular flange for a water pump. The flange body and boss of this utility model are both designed as triangular flanges, which, together with the support platform and connecting ribs, reduce the cost of the flange, enhance its strength, and improve its stability.

[0004] To achieve the above technical objectives, this utility model adopts the following technical solution: a water pump triangular flange, comprising a body, the body being triangular in shape, with a bolt hole at each of the three corners of the body, a boss being provided on the first side of the body, the boss being triangular in shape, a shaft hole being provided at the center of the boss, the shaft hole penetrating the body, three bolt hole support platforms and one shaft hole support platform being provided on the second side of the body, the three bolt hole support platforms corresponding to the three bolt holes and having corresponding through holes, the shaft hole support platform corresponding to the shaft hole and having corresponding through holes, long connecting ribs being provided between adjacent bolt hole support platforms, and short connecting ribs being provided between the three long connecting ribs and the shaft hole support platform.

[0005] Furthermore, the three sides of the boss are parallel to the three sides of the body.

[0006] Furthermore, the boss has clearance grooves at its three corners, and the clearance grooves are concentric with the bolt holes.

[0007] Furthermore, the boss is provided with a second chamfer.

[0008] Furthermore, the body is provided with a first chamfer.

[0009] Furthermore, the shaft hole is provided with a sloping step.

[0010] Furthermore, the bolt hole support platform is provided with a third chamfer.

[0011] Furthermore, the shaft hole support platform is provided with a fourth chamfer.

[0012] Furthermore, the bolt hole support platform is flush with the shaft hole support platform.

[0013] Furthermore, the height of the bolt hole support platform and the shaft hole support platform is higher than the height of the long connecting rib and the short connecting rib.

[0014] In summary, this utility model achieves the following technical effects:

[0015] This utility model sets both the flange body and the boss as triangles. By utilizing the principle of triangular stability, it can reduce the material cost of the flange and increase its stability. The two triangles are isosceles triangles, which have better strength.

[0016] This utility model is equipped with three support platforms, which extends the length of the support, resulting in good stability and strength;

[0017] This utility model incorporates connecting ribs to enhance strength. Attached Figure Description

[0025] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0026] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0028] Example:

[0029] Figure 1 This is a top view of a water pump triangular flange. Figure 2 yes Figure 1 A-A direction cross-sectional diagram Figure 3 yes Figure 1 A top-down 3D view. Figure 4 yes Figure 1The image is a three-dimensional view from a low angle, including a body 1, which is triangular in shape. Each of the three corners of the body 1 has a bolt hole 3. A protrusion 2, also triangular in shape, is located on the first side of the body 1. A shaft hole 4 is located at the center of the protrusion 2, penetrating the body 1. Three bolt hole support platforms 5 and one shaft hole support platform 6 are located on the second side of the body 1. The three bolt hole support platforms 5 correspond to the three bolt holes 3 and have corresponding through holes. The shaft hole support platform 6 corresponds to the shaft hole 4 and has corresponding through holes. Long connecting ribs 7 are provided between adjacent bolt hole support platforms 5, and short connecting ribs 8 are provided between the three long connecting ribs 7 and the shaft hole support platform 6.

[0030] This invention designs both the flange body and the boss as triangles. Triangular structures offer good stability and reduce overall weight without compromising strength. In this embodiment, all triangles are isosceles, further enhancing strength. Bolt holes 3, fitted with fixing bolts (not shown), are fixed to the transmission wheel for transmission. The water pump's rotating shaft is installed in the shaft hole 4. Three bolt hole support platforms 5 and one shaft hole support platform 6 extend the support length between the bolts and the flange, increasing stability. This reduces the original flange body thickness, retaining only three support platforms without affecting stability, while also reducing weight and cost. Long connecting ribs 7 and short connecting ribs 8, working in conjunction with the three support platforms, further enhance stability and strength.

[0031] The three sides of the boss 2 are parallel to the three sides of the body 1, resulting in better stability.

[0032] The boss 2 has three corners with relief grooves 21, which are concentric with the bolt holes 3 to prevent the bolts from being affected when they are installed.

[0033] The boss 2 is provided with a second chamfer 22. The body 1 is provided with a first chamfer 11. The bolt hole support 5 is provided with a third chamfer 51. The shaft hole support 6 is provided with a fourth chamfer 61.

[0034] The shaft hole 4 is provided with a sloping step 41 to facilitate interference fit.

[0035] The bolt hole support platform 5 is flush with the shaft hole support platform 6 to ensure stability during assembly.

[0036] The height of the bolt hole support platform 5 and the shaft hole support platform 6 is higher than the height of the long connecting rib 7 and the short connecting rib 8 to prevent the connecting ribs from affecting the assembly.

[0037] The flange material of this utility model is SMF4040.

[0038] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
