Abstract
The utility model provides a seal blocking cover resistant to high pressure, and relates to the sealing technical field. A high-pressure supporting part is arranged at the bottom of the center of a blocking cover body, the outer edge of the high-pressure supporting part is provided with an impact-resistant part, the outer edge of the upper end of the blocking cover body is a rubber seal part, the high-pressure supporting part and the impact-resistant part are of an integration type metal frame structure, and the rubber seal part is arranged above the impact-resistant part. The seal blocking cover has the advantages of being resistant to high pressure, resistant to impact, simple to install, high in reliability and the like, is low in cost, resolves the problem of leakage of a high-pressure oil line, has good economic benefits, and has strong market competitiveness.
Description
Technical field:
The utility model relates to technical field of sealing technology, is specifically related to a kind of high voltage bearing sealing blanking cover.
Background technique:
Two clutch system speed changers have the plurality of advantages such as short, power free of losses of gearshift time, but along with the research and extension of two clutch system speed changers production domesticization, how effectively to solve the sealing problem of speed changer mesohigh oil circuit, become the research direction of sealing industry.
Existing sealing device structure is complicated, installs loaded down with trivial detailsly, and leakage problem appears in occasional, and the cost of each side is higher, and cost performance is low.
The model utility content:
The purpose of this utility model is to provide a kind of high voltage bearing sealing blanking cover, it have high pressure resistant, shock-resistant, simple, reliability high are installed, and cost is lower, solves the leakage problem of high-pressure oil passage, and have good economic benefit, have the stronger market competitiveness.
In order to solve the existing problem of background technique, the utility model is by the following technical solutions: it comprises blanking cover body 1, the bottom at blanking cover body 1 center is provided with high pressure supporting element 2, the outer rim of high pressure supporting element 2 is provided with shock resistance part 4, the outer rim of blanking cover body 1 upper end is rubber seal 3, high pressure supporting element 2 and shock resistance part 4 are the integral type metal framework structure, and rubber seal 3 is arranged on the top of shock resistance part 4.
Described high pressure supporting element 2 is arc structure.Guarantee that product when being subject to impacting with high pressure, increasing lifting surface area, and pressure is evenly distributed, can keep rigidity, the intensity of product, make the size of product can because compression shock changes, not stop the hidden danger of product leakage.
Described shock resistance part 4 is tapered configuration.Product can be advanced under the effect of external force vertically, until arrive the groove position, after can guaranteeing that product is subject to internal pressure, play can not occur, even come off, avoid the hidden danger of product leakage.
The utlity model has high pressure resistant, shock-resistant, simple, reliability high are installed, and cost is lower, solves the leakage problem of high-pressure oil passage, and has good economic benefit, has the stronger market competitiveness.
Description of drawings:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that the A-A of Fig. 1 is to sectional view;
Fig. 3 is stereogram of the present utility model.
Embodiment:
Referring to figs. 1 through Fig. 3, this concrete enforcement by the following technical solutions: it comprises blanking cover body 1, the bottom at blanking cover body 1 center is provided with high pressure supporting element 2, the outer rim of high pressure supporting element 2 is provided with shock resistance part 4, the outer rim of blanking cover body 1 upper end is rubber seal 3, high pressure supporting element 2 and shock resistance part 4 are the integral type metal framework structure, and rubber seal 3 is arranged on the top of shock resistance part 4.
Described high pressure supporting element 2 is arc structure.Guarantee that product when being subject to impacting with high pressure, increasing lifting surface area, and pressure is evenly distributed, can keep rigidity, the intensity of product, make the size of product can because compression shock changes, not stop the hidden danger of product leakage.
Described shock resistance part 4 is tapered configuration.Product can be advanced under the effect of external force vertically, until arrive the groove position, after can guaranteeing that product is subject to internal pressure, play can not occur, even come off, avoid the hidden danger of product leakage.
the hole wall interference fit of rubber seal 3 and gearbox in this concrete enforcement, guarantee the sealing of product, the arc structure of high pressure supporting element 2, can guarantee that product is when being subject to impacting with high pressure, increase lifting surface area, and pressure is evenly distributed, the rigidity that can keep product, intensity, the size of product can not changed because of compression shock, avoid the hidden danger of product leakage, shock resistance part 4 has certain angle of inclination, when product is installed, shock resistance part 4 is compressed in diametric(al), product can be advanced under the effect of external force vertically, until arrive the groove position, after product is in place, shock resistance part 4 can be because self elasticity of metal frame, return back to the primary dip angle, the external diameter of groove and shock resistance part 4 forms the rigidity interference, after can guaranteeing that product is subject to internal pressure, play can not occur, come off.
This is concrete implement to have high pressure resistant, shock-resistant, simple, reliability high are installed, and cost is lower, solves the leakage problem of high-pressure oil passage, and has good economic benefit, has the stronger market competitiveness.
