Abstract
The utility model relates to a hollow annular rubber sealing element, which consists of a sealed rubber pipe body and a cavity, wherein the cavity is positioned in the sealed rubber pipe body, and the whole body is in an annular shape. A manufacture method comprises the following steps that: firstly, the hollow rubber pipe is manufactured by an extruding machine, then, a corresponding connecting element is pressed by fragile materials, adhesive tapes at two end surfaces of the hollow rubber pipe are preliminarily connected into an annular shape by the connecting element, the adhesive tapes are connected through hot vulcanization by a vulcanizing machine, and finally, the fragile connecting element positioned in the hollow rubber pipe is crushed, wherein the cavity is a gas bag, pressure gas in the cavity can equably press the periphery of the sealed rubber pipe body after the cavity is assembled and pressed, and, the sealed rubber body can perfectly and correspondingly generate corresponding deformation even through certain errors exist between sealing bonding surfaces, so the sealing performance is improved, the friction force is reduced, and the defects of permanent deformation generated because of pressure deviation can be avoided. The utility model is favorable for improving the transmission efficiency of a mechanical transmission mechanism and reducing the power consumption, and the utility model breaks through the technical prejudice of industry.
Description
[technical field]
The utility model relates to rubber seal, relates in particular to the ring-shaped rubber Sealing.
[background technique]
O-ring seals is the typical part of annular rubber sealing element, it uses extremely extensive in sealing occasions such as axis hole cooperation, end face seals, it is the most frequently used a kind of Sealing, can work long-term effectively in order to guarantee seal ring, except the material of compressibility, amount of tension and the seal ring of choose reasonable seal ring, rational axis hole quality of fit must be arranged also.When determining the compressibility of seal ring, should guarantee that seal ring can be subjected to enough sealing surface contact pressures, the little frictional force of trying one's best and avoid producing permanent deformation because of biasing.In the practical set process, if magnitude of interference is too big, seal ring is easy to be sheared damage, otherwise seal ring loses envelope again easily.Under the conditional request of high pressure, high vacuum, high elasticity sealing, higher to the accuracy of manufacturing requirement of O-ring seals.According to force analysis and the sealing mechanism of O-ring seals under in working order, if O-ring seals is designed to hollow-core construction, not only the stressed meeting of seal ring is more reasonable, sealability can be better, and can further relax the requirement on machining accuracy of Sealing, quality of fit to axis hole requires also not too high, making has the certain deformation space behind the seal ring pressurized, under the prerequisite that guarantees sealability, can guarantee that Sealing has enough contact pressures, can reduce frictional force again, avoid seal ring because of being out of shape the excessive critical defects such as permanent deformation that produce.Adopting the hollow O-ring seals to help improving the transmission efficiency of mechanical transmission mechanism, reduce power consumption, is the desirable seal product that improves the secondary sealability of China's mechanical transmission.Hollow structure is suitable equally for the annular seal of other sectional shape.The claimant does not find the hollow and annular rubber seal as yet by patent and prior art literature search, does not more find related methods of production.
[model utility content]
The purpose of this utility model provides a kind of hollow and annular rubber seal.
A kind of hollow and annular rubber seal, its integral body is annular enclosed structure, and it is characterized in that: its cross section is made up of enclosed shape rubber body and cavity, and cavity is positioned at enclosed shape rubber body.
Further, the sectional shape of cavity is similar to the shape of enclosed shape rubber body.
Further, the sectional shape of cavity is circular.
A kind of manufacture method of hollow and annular rubber seal comprises the steps:
1. earlier make hollow rubber pipe as the sectional shape of glue Sealing with extruder according to hollow and annular;
2. according to cavity shape and size requirement, with easy material crushed compacting link, for example moulding sand or earth or chalk ash suppress link and oven dry;
3. according to the length of run clip hollow rubber pipe of hollow and annular rubber seal, connect end faces at two of hollow rubber pipe and add and be coated with adhesion glue, link is inserted in the endoporus of hollow rubber pipe, the hollow rubber pipe is tentatively connected into ring-type;
4. with the hot vulcanization mould hot vulcanization gummed being carried out in the joint of hollow and annular rubber seal with vulcanizer is connected;
5. the link in the hollow and annular rubber seal is crushed.
Because annular rubber sealing element is designed to hollow structure, and provide concrete making method, earlier make the hollow rubber pipe with extruder, make link with friable material again, connect with of the two ends transition of frangible link then the hollow rubber pipe, be with the glue hot vulcanization to connect with vulcanizer, will be arranged in the frangible link crushing of hollow rubber pipe at last.This hollow and annular rubber seal can reduce the machining accuracy of Sealing and the quality of fit requirement of axis hole significantly under the prerequisite that guarantees sealability.Cavity in the hollow and annular rubber seal is exactly in fact an air bag, in hollow ring shape rubber seal is packed seal groove into and after the compressive fitment, the inevitable pressurized in enclosed shape rubber outer ring, because the pressure of the pressed gas in the cavity is consistent, it can force the compressing power equalization all around of enclosed shape rubber outer ring, even there is certain error between the sealed faying face, enclosed shape rubber outer ring also can be complied with well and be produced corresponding distortion, can guarantee Sealing to have enough and contact pressure uniformly, it can reduce the frictional force of sealing surface for rotary type sealing surface or fore and aft motion type sealing surface; Then can avoid because of pressing oblique presentation to give birth to the permanent deformation defective for the sealing surface of fixing seal type.This hollow and annular rubber seal uses under high compression amount state, enclosed shape rubber outer ring had both had sufficient deformation space, has the high elasticity that rubber itself has again, help further improving the transmission efficiency of mechanical transmission mechanism, reducing power consumption, is the desirable seal product that improves the secondary sealability of mechanical transmission.Its using scope is extensive, can be applicable to aviation, on automobile, medical apparatus and all kinds of machinery, be specially adapted to accurate sealing such as axis hole cooperation, the cooperation of fixing seal end face occasion for rotary type or telescopic type, if the hollow and annular rubber seal is applied on the dynamic seal (packing) parts such as sealed door, not only sealing is unique, and open and close all have the buffering sound absorption, switch is light, and the noise of generation is extremely low.
The utility model has been broken the Sealing industry and has been generally acknowledged the technology prejudice that the hollow and annular rubber seal can not be produced.
