Abstract
The utility model provides a light weight oil seal. The light weight oil seal comprises rubber, a support ring and a spring, wherein meshes are distributed in the support ring, and the support ring is integrated with the rubber part through sulfuration. According to the improved oil seal provided by the utility model, due to the adoption of the support ring with the mesh structure, the weight of the oil seal can be reduced without lowering the strength, and the light weight is realized; meanwhile, the contact area of the rubber and the support ring is increased due to the existence of the meshes, and the rubber is clung to the support ring through the meshes, and can not peel off from the support ring easily, so that the stability of the oil seal in long-term use is improved.
Description
Technical field
The utility model relates to the Sealing technical field, relates in particular to a kind of lightweight oil sealing.
Background technique
Auto parts and components are towards light-weighted future development.Research shows, the quality minimizing 10% of a car, and its fuel economy can improve 3%～4%, and the discharge of automobile simultaneously also can reduce.Oil sealing automobile power, transmission, travel and the system such as turn in as seal element, application is arranged, its gross weight does not coexist hundreds of between several myriagrams according to vehicle, so the lightweight of oil sealing also can cause the automobile gross weight to reduce.
As shown in Figure 1, oil sealing consists of support ring 1, rubber 2 and spring 3 usually.Support ring 1 material is generally cold rolled sheet.In order to reduce the weight of oil sealing, common way is to adopt the thinner cold rolled sheet of thickness to make support ring, or adopts the less metal of density to make support ring, as aluminum alloy etc.But when adopting the thinner cold rolled sheet of thickness to make support ring, due to the support ring thickness reduction, its rigidity descends, and causes oil sealing and fitting seat hole coordinate force to reduce, oil sealing easily is subjected to displacement, and causes inefficacy; And the metal of employing less dense, as aluminum alloy, is made support ring easily because it has larger thermal expansion coefficient, equally easily cause oil sealing and fitting seat hole coordinate force to go wrong.Simultaneously, owing to adopting thinner cold rolled sheet or the lower metal of density, cause the oil sealing strength decreased, it is easily deformed.
The purpose of this utility model just is to solve the problems of the technologies described above, and on the basis that does not reduce the oil sealing performance, reduces the weight of oil sealing, realizes the lightweight of oil sealing.
The model utility content
Technical problem to be solved in the utility model is, a kind of novel lightweight oil sealing is provided, and on the basis that does not reduce the oil sealing performance, reduces the weight of oil sealing, realizes the lightweight of oil sealing.
The utility model provides a kind of lightweight oil sealing, and it comprises rubber, support ring and spring, on described support ring, is placed with mesh, and support ring and rubber part are combined into one by vulcanization.
Each in described mesh can be triangle, rectangular, square, circle.
When described mesh is circle, the diameter of each aperture of described mesh is 1～3mm.
The material of described support ring is cold rolled sheet.
The mesh that rule on described support ring is arranged makes cold rolled sheet prepare by impact briquetting, and by the support ring after impact briquetting, the support ring after impact briquetting is L shaped structure.
The beneficial effects of the utility model:
Oil sealing after the utility model improves has mesh-structured support ring owing to having adopted, and has reduced the weight of oil sealing under the prerequisite that does not reduce its intensity, has realized lightweight.Simultaneously, due to the existence of mesh, increase the area of contact of rubber and support ring, and made rubber seek connections with support ring by mesh, made that rubber and support ring are more difficult to be peeled off, improved the stability of the long-term use of oil sealing.
The accompanying drawing explanation
Fig. 1 is for improving the Front oil seal structural drawing;
Fig. 2 is the lightweight oil seal structure figure after improving.
Embodiment
The utility model provides a kind of lightweight oil sealing, it consists of rubber, support ring and spring, be placed with mesh on described support ring, described support ring makes oil sealing have certain rigidity, guarantee that oil sealing is installed in a hole reliably, rubber is for realizing the sealing function of oil sealing, and spring can provide to the sealing lip of oil sealing lasting and stable radial force.
Described support ring is for guaranteeing that oil sealing has certain intensity, can guarantee oil sealing install after position fix, support ring and rubber part are combined into one by vulcanization, rubber part seals axle, hole for realizing.
Each mesh in described mesh can be various conventional shapes, as triangle, rectangular, square, circle etc., is preferably circle.
When described mesh is circle, the diameter of each aperture of described mesh is 1～3mm, in this dimensional range, both can guarantee that support ring intensity is close with the support ring intensity of being made by common cold rolled sheet, can reach again the purpose that reduces weight.
The material of described support ring is cold rolled sheet.
The mesh that rule on described support ring is arranged makes cold rolled sheet prepare by impact briquetting, and by the support ring after impact briquetting, the support ring after impact briquetting is L shaped structure.
Below with reference to accompanying drawing, the utility model is described in further details.
Lightweight oil sealing provided by the invention as shown in Figure 2, it consists of rubber 2, support ring 1 and spring 3, on described support ring 1, is placed with mesh, and each mesh is circular, and diameter is 2mm.
All above-mentioned these intellectual properties of primary enforcement, do not set restriction this new product of other forms of enforcement and/or new method.Those skilled in the art will utilize this important information, and foregoing is revised, to realize similar implementation status.But all modifications or transformation belong to the right of reservation based on the utility model new product.
The above, it is only preferred embodiment of the present utility model, be not the utility model to be done to the restriction of other form, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equivalent variations.But every technical solutions of the utility model content that do not break away from, any simple modification, equivalent variations and the remodeling above embodiment done according to technical spirit of the present utility model, still belong to the protection domain of technical solutions of the utility model.
