Abstract
The utility model provides a novel no spring -loaded oil seal of high -speed operation of adaptation belongs to the oil blanket field. It has solved the problem of sealing when current oil blanket can not satisfy high temperature, high pressure, the high -speed operation. This novel no spring -loaded oil seal of high -speed operation of adaptation is become by skeleton and rubber body group, be equipped with point form lip on the rubber body, and the lip is for becoming through the rotation of cutting rubber bodily form. This oil blanket is specially made for engine design, is applied to engine fore bearing department, and the lip passes through the rotation of cutting rubber bodily form, guarantees the sharp -pointed degree of lip, makes oil blanket installation back guarantee to become the line contact area with the axiform, according to the follow -up nature and the power of holding tightly of rubber body waist rubber, satisfies and realize sealed effect under the circumstances of high speed, high temperature to can satisfy cavity internal pressure.
Description
Technical field
The utility model belongs to oil seal technique field, relates to a kind of novel adaptation and runs up without spring-loaded oil seal.
Background technique
Oil sealing is used to the mechanical component of oil sealing, and the parts needing in transmission part to lubricate are isolated with parts of exerting oneself by it, are unlikely to allow oil seepage.
But original sealing means is ordinary construction oil sealing form, can not meet inside cavity pressure, later stage high temperature, high pressure, sealing when running up can not be met.
Summary of the invention
The purpose of this utility model is for the above-mentioned problems in the prior art, provide a kind of can meet run up, the novel adaptation of high temperature and high pressure usage requirement runs up without spring-loaded oil seal.
The purpose of this utility model realizes by following technical proposal: a kind of novel adaptation runs up without spring-loaded oil seal, it is characterized in that: described oil sealing is made up of skeleton and rubber body, described rubber body is provided with pointed lip, and described lip is for be formed by circumgyration incision rubber body, and form linear contact lay band by lip and axle after oil sealing is installed.
This oil sealing aims at engine design manufacture, be applied to motor fore bearing place, lip is formed by circumgyration incision rubber body, ensure the sharpness of lip, ensure after oil sealing is installed to form linear contact lay band with axle, according to trackability and the enclasping force of rubber body waist rubber, meet and realize sealing effect when high speed, high temperature, and inside cavity pressure can be met.
Run up without in spring-loaded oil seal in the novel adaptation of above-mentioned one, described skeleton is formed by punching press, and assembles with described rubber body and form integrative-structure.
Skeleton adopts special-shaped punching press form, ensures, to press-fit product in process indeformable, to realize sealing.
Run up without in spring-loaded oil seal in the novel adaptation of above-mentioned one, described rubber body comprises sealing lip, lip is located on sealing lip, and between sealing lip and rubber body, form U-shaped dashpot, described skeleton is provided with L shape flange, and described flange surrounds outside dashpot and flared end portions is against bottom sealing lip.
Play good sealing by the support of sealing lip and flange, avoid mounting spring.
Run up without in spring-loaded oil seal in the novel adaptation of above-mentioned one, two sides that described rubber body connects with lip are the plane structure that circumgyration incision rubber body is formed.
Compared with prior art, the utility model tool has the following advantages:
1, this oil seal lip adopts circumgyration incision rubber body to be formed, and without spring, sizing material resistance to medium is good.
2, this oil sealing can realize the sealing of internal transmission oil, and high temperature resistant, meets inside cavity pressure, maximumly reaches 0.6Mpa.
3, this oil sealing forms integral structure, and skeleton adopts special-shaped punching press form, ensures, to press-fit product in process indeformable, to realize sealing.
4, the manufacture process of this oil sealing is simple, and efficiency is high.
5, the long service life of this oil sealing.

2, rubber body; 21, sealing lip; 22, lip; 23, dashpot.
Embodiment
Be below specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As shown in Figure 1, a kind of novel adaptation of the utility model runs up without spring-loaded oil seal, and oil sealing is made up of skeleton 1 and rubber body 2, and rubber body 2 is provided with pointed lip 22, and lip 22 is for be formed by circumgyration incision rubber body 2, and form linear contact lay band by lip 22 and axle after oil sealing is installed.
Further, skeleton 1 is formed by punching press, and assembles with rubber body 2 and form integrative-structure.Rubber body 2 comprises sealing lip 21, and lip 22 is located on sealing lip 21, and forms U-shaped dashpot 23 between sealing lip 21 and rubber body 2, and skeleton 1 is provided with L shape flange 11, and flange 11 surrounds outside dashpot 23 and flange 11 end and is against bottom sealing lip 21.Two sides that rubber body 2 connects with lip 22 are the plane structure that circumgyration incision rubber body 2 is formed.
Because this oil sealing is without spring, therefore sizing material resistance to medium is good, and due to lip 22 pointed, and sealed by the servo-actuated performance of rubber body 2 waist rubber and enclasping force, make to reach good sealing, and high temperature resistant, meet inside cavity pressure, maximumly reach 0.6Mpa.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present utility model or surmount the scope that appended claims defines.
Although more employ the terms such as skeleton 1, flange 11, rubber body 2, sealing lip 21, lip 22, dashpot 23 herein, do not get rid of the possibility using other term.These terms are used to be only used to describe and explain essence of the present utility model more easily; The restriction that they are construed to any one additional is all contrary with the utility model spirit.
