Abstract
The invention discloses an oil seal for being used at a middle and high voltage. The oil seal includes an outside frame, a rubber sealing body, an inner frame and a spring. The rubber sealing body is wrapped by the said outside frame, the inner frame is wrapped by the rubber sealing body and the spring is positioned on the right side of the rubber sealing body. The advantages of the oil seal are that the stability of the oil seal can be improved when a lip of the oil seal is under pressure and the temperature is high by bending the outside frame to support the lip; and by adopting encapsulation design at peripheries of inner and outside frames and interference fit pressing with the outside frame, the sealing effect and the performance of the oil seal are improved and manufacturing processes of the oil seal are simplified.
Description
Technical field
The present invention relates to the oil seal technique field, relate in particular to a kind of mesohigh that is used for Intermediate High Pressure occasion (like small-sized oil pump etc.) and use the rotation combination oil sealing.
Background technique
Like product is as shown in Figure 1 in the market, comprises outer skeleton 1, inner frame 2, PTFE support ring 3, spring 4, rubbery sealed body 5, and it utilizes PTFE support ring 3 to make the lip support ring; Take the rolling assembling mode to connect outer skeleton 1 and inner frame 2 respectively, inner frame 2, the inboard is provided with rubbery sealed body 5; Rubbery sealed body 5 right parts are provided with spring 4; Because PTFE support ring 3 hardness and intensity when temperature rises all can reduce, support effect subtracts, thereby causes the withstand voltage not enough inefficacy that produces; In addition, occur seepage easily between rolling outer skeleton 1 of combination and the inner frame 2, and middle PTFE support ring 3 elasticity are not enough, can not play good seal action, and cause seepage to lose efficacy.
Summary of the invention
The purpose of this invention is to provide a kind of mesohigh and use the rotation combination oil sealing; Overcome the shortcoming of existing product, utilized outer skeleton bending to support lip, improved the stability under the lip pressurized and the condition of high temperature; The inner frame periphery adopts the encapsulate design simultaneously; Press-fit with outer skeleton interference fit, not only improved sealing effect but also simplified technology, improved the usability of product greatly.
In order to reach above-mentioned purpose of design, the technological scheme that the present invention adopts is following:
A kind of mesohigh is used the rotation combination oil sealing, comprises outer skeleton, rubbery sealed body, inner frame and spring, parcel rubbery sealed body in the said outer skeleton, and parcel inner frame in the rubbery sealed body, said rubbery sealed body right part is provided with spring.
Said inner frame and rubbery sealed body sulfidization molding, rubbery sealed body coats inner frame fully, and said rubbery sealed body is an interference fit with outer skeleton.
Said outer skeleton and rubbery sealed body fitting surface are provided with protruding structure, protruding structure support rubber seal and interior inner frame thereof.
The range of working pressure of said rubbery sealed body is: 0～1MPa.
Mesohigh of the present invention with the beneficial effect of rotation combination oil sealing is: use outer skeleton nipple support lip, good stability is withstand voltage stronger; Rubbery sealed body is arranged, good airproof performance between inner frame and outer skeleton; Simple in structure, easy to operate, improved manufacturing efficiency.

Among the figure: 1, outer skeleton; 2, inner frame; 3, PTFE support ring; 4, spring; 5, rubbery sealed body.
Fig. 2 is the schematic representation of the described mesohigh of the embodiment of the invention with the rotation combination oil sealing.
Among the figure: 1, outer skeleton; 2, inner frame; 4, spring; 5, rubbery sealed body.
Embodiment
Below in conjunction with accompanying drawing optimum implementation of the present invention is done further detailed description.
As shown in Figure 2; The described mesohigh of the embodiment of the invention is used the rotation combination oil sealing, comprises outer skeleton 1, rubbery sealed body 5, inner frame 2 and spring 4, parcel rubbery sealed body 5 in the said outer skeleton 1; Parcel inner frame 2 in the rubbery sealed body 5, said rubbery sealed body 5 right parts are provided with spring 4.
Said inner frame 2 and rubbery sealed body 5 sulfidization moldings, rubbery sealed body 5 coats inner frame 2 fully, makes inner frame 2 bonding firm with rubbery sealed body 5; Said rubbery sealed body 5 is an interference fit with outer skeleton 1, press-fits the combination back and guarantees its sealing.
Said outer skeleton 1 is provided with protruding structure with rubbery sealed body 5 fitting surfaces, protruding structure support rubber seal 5 and interior inner frame 2 thereof, and the voltage endurance capability of raising product prevents that high pressure from damaging.
Mesohigh of the present invention is used the rotation combination oil sealing, under the pressure below the 1MPa, has better seal stability, and low pressure occasion rubbery sealed body 5 self servo-actuated property is good, is supported by metal inner frame 2 during high pressure, effectively releases the pressure, and avoids damaging.
This embodiment is the preferred embodiments of the present invention, can not limit the present invention, and concrete each item rights protection scope is defined by the claims.
Claims (4)
