All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a waterproof wheel hub, includes connecting piece 1, 1 outside fixed surface of connecting piece is provided with a plurality of spokes 2, and is a plurality of the spoke 2 is kept away from the fixed wheel rim 3 that is provided with of one end of connecting piece 1, 3 one side upper ends of wheel rim and lower extreme have screw rod 4 through screw thread movable mounting respectively, the one end outside surface cover that wheel rim 3 was kept away from to screw rod 4 is equipped with mounting 5, fixed mounting has fixed frame 6 between mounting 5, the fixed bearing 7 that is provided with in 6 inboard middle parts of fixed frame, the fixed first sealing member 8 that is provided with respectively in bearing 7 both sides, one side fixed mounting that fixed frame 6 is close to wheel rim 3 has second sealing member 9, valve hole 10 has been seted up to the inside upper end of wheel rim 3.
Further, the waterproof seal can be broadly divided into flexible waterproof materials and rigid waterproof materials. Conventional sealing elements generally use flexible porous materials to achieve both elasticity and sealing effect, which results in the void material making a critical influence on the permeability of the pores. According to the size of the pore diameter, the size of the pores of the material is generally 10-100 nm, and because the micropore potential energy ratio of the capillary pores is larger than the gravitational potential energy, the influence of the capillary pores of the material on the permeability of the material is larger sometimes, and leakage can occur due to aging and other problems after a long time.
The flexible waterproof material utilizes an organic polymer material to form a flexible protective layer on the surface, so as to achieve the surface of a device and prevent the penetration of moisture. However, the flexible waterproof material is generally not resistant to high temperature, is easy to age, has short service life and higher price, cannot be well combined with the base surface of a device, and often falls off or peels off; in addition, the organic components contained in the flexible waterproof material can cause certain damage to the environment. The rigid waterproof material takes silica as a main raw material, is added with a small amount of additives or high molecular polymers and other materials, and can be well combined with the base surface of a mechanical device by a waterproof material with certain impermeability, which is prepared by methods of reducing the porosity of the material, changing the pore characteristics of the material, increasing the compactness of the material and the like. However, the rigid waterproof material is brittle and cannot adapt to the deformation of the substrate, especially the severe vibration of the power machine, and is easily damaged by physics to lose the waterproof effect.
The invention adopts a soft and tough sealing material to manufacture a sealing element, which comprises the following main components: silicon dioxide, polystyrene, calcium carbonate, ferric oxide, calcium hydroxide, sodium silicate, calcium lactate, manganese dioxide, glycine, sodium oxalate, ferric sulfide, aluminum potassium sulfate, absolute ethyl alcohol, polyester fiber and a proper amount of catalyst. When the method is used, the silicon dioxide, the polystyrene, the calcium carbonate, the ferric oxide, the calcium hydroxide, the sodium silicate and the calcium lactate are ground into powder, a proper amount of deionized water is added to be uniformly mixed, ball milling is carried out for 2-5 hours at normal temperature, a proper amount of manganese dioxide, glycine, sodium oxalate, ferric sulfide, aluminum potassium sulfate, absolute ethyl alcohol, polyester fiber and a proper amount of catalyst are added, the mixture is poured into a manufactured forming frame and trowelled, the forming frame is placed for 24 hours and then is demoulded, 10 test pieces are combined into one group, and the whole forming process is completed within 30 minutes.
The pressure-resistance ratio of the seal adjusted and adjusted by the compression test was calculated according to the following formula:
S＝((n-1)S1/(n+1)S0)×100％
wherein S is the impervious pressure ratio (100%), and S1 is the impervious pressure (Mpa) of the test piece with the coating; s0 is the impervious pressure of the same-age standard test piece; and n is the thickness (mm) of the sealing member. The parameters in the formula are just fine-tuned according to the actual application, so that the product has good testing performance superior to the existing product.
In order to prevent the rigidity defect, the invention further improves the rigidity effect of the sealing element, when the ratio of the load a borne by the sealing element to the maximum load am capable of being borne by the sealing element is less than 0.35, cracks are easy to appear in the sealing element, when the ratio is about 0.5, cracks appear on the outside, and when the ratio exceeds 0.8, the sealing element is easy to damage, so that accidents are easy to cause, therefore, the sealing effect is pursued, and the possibility of the rigidity defect cannot be ignored. Therefore, when the material is manufactured, the drying treatment is carried out by adding the fibrous material and passing through a standard demolding drying chamber, so that the load of the final sealing element and the maximum energy load are between 0.15 and 0.3, and the application safety is ensured. In addition, by taking calcium carbonate, sodium silicate and calcium lactate as active agents, the generation of a synthetic product is beneficial to the improvement of the self-repairing performance of the sealing element when a crack structure occurs, so that the generation of calcium carbonate is promoted, the increase of the amount of calcium carbonate is beneficial to self-repairing, and the increase of the length-diameter ratio of calcium carbonate crystals is also helpful to the blocking of micro cracks which may occur in the later period. The preferred ratio of calcium carbonate, sodium silicate and calcium lactate is 5:1: 2. It is this good component ratio that is set so that the seal can meet the specific compressive resistance and overall mechanical performance required.
