Abstract
The utility model discloses polytetrafluoroethylene oil sealing with a side wall boss and relates to polytetrafluoroethylene oil sealing. The polytetrafluoroethylene oil sealing comprises a main sealing lip, an auxiliary sealing lip, a support part, a rubber body and the side wall boss, wherein the main sealing lip is composed of polytetrafluoroethylene sheets and bonded on the rubber body and the support part, the auxiliary sealing lip is arranged below the main sealing lip, the support part is coated in the rubber body, and the side wall boss is arranged on the inner wall of the support part. The polytetrafluoroethylene oil sealing with the side wall boss solves the problem that in the prior art, the rubber body of the inner wall of the support part causes appearance of a product to be ugly, and the rubber body is not even in bonding. The polytetrafluoroethylene oil sealing strengthens adhesive force of the polytetrafluoroethylene sheets, the rubber body and the support part, avoids falling of the polytetrafluoroethylene sheets, simultaneously plays a role of positioning of the support part in the process of sulfide forming of the product, and not only prevents the support part from exposing and rusting, but also can ensure that the product is beautiful.
Description
Technical field:
The utility model relates to a kind of teflon seal, is specifically related to a kind of teflon seal with the sidewall boss.
Background technique:
Teflon seal and the difference of General Purpose Rubber rotary oil seal replace rubber lip with teflon plate exactly, because polytetrafluoroethylmaterial material has the characteristics such as good heat resistance, solvent resistance, wear resistance, non-viscosity, self lubricity, surface friction drag is little, wear extent is little so teflon seal has, long service life, media-resistant, high temperature resistant, high pressure resistant and seal the performances such as reliable, and therefore at home and abroad engine shop uses more and more extensive.As shown in Figure 1, its basic structure comprises primary seal lip 1, secondary sealing lip 2, supporting element 3 and rubber body 4, and primary seal lip 1 is bonded on rubber body 4 and supporting element 3 by teflon plate and consists of; Primary seal lip 1 below arranges secondary sealing lip 2, and secondary sealing lip material is nonwovens or rubber body; Supporting element 3 is coated on rubber body 4 the insides.Mainly there is following defective in the teflon seal of existing structure: teflon plate and rubber body and supporting element are not sticking in forming process, cause teflon plate to break away from, products waste; Supporting element axially and is not radially located accurately in forming process, easily causes product sidewall rubber body coating inconsistent, and product is oval, and difficulty is installed when causing product to use; The supporting element inwall that teflon seal is exposed is exposed to the outside, is easy to get rusty, and causes product failure; Supporting element inwall exposed surface allows to adhere to firmly rubber body during formed product in addition, because the rubber body that adheres to is inhomogeneous, causes product appearance ugly.
The model utility content:
The purpose of this utility model is to provide a kind of teflon seal with the sidewall boss, it solves, and in prior art, the supporting element inwall adheres to the non-uniform rubber body and causes product appearance ugly, strengthen the Adhesion force of teflon plate and rubber body, supporting element, prevent that teflon plate from coming off; Simultaneously when the product sulfidization molding, can play the effect of supporting element location, can prevent that supporting element is exposed gets rusty, and can guarantee that again product is attractive in appearance.
In order to solve the existing problem of background technique, the utility model is by the following technical solutions: it comprises primary seal lip 1, secondary sealing lip 2, supporting element 3, rubber body 4, sidewall boss 5; Primary seal lip 1 is made of teflon plate, is bonded on rubber body 4 and supporting element 3, and primary seal lip 1 below arranges secondary sealing lip 2, and supporting element 3 is coated on rubber body 4 the insides, and sidewall boss 5 is arranged on the inwall place of supporting element 3.
The material of described secondary sealing lip 2 is nonwovens or rubber body, mainly plays envelope dirt;
Described supporting element 3 is coated on rubber body 4 the insides, can avoid the distortion after product is installed, and improves the performance of product;
Described sidewall boss 5 is the rubber body boss of a circle circumference uniform distribution, be arranged on supporting element inwall place, in the teflon seal forming process, both direction positioning supporting part 3 axially and radially, guarantee the position of supporting element, the rubber body that guarantees the coating of supporting element outer rim is even, and sidewall boss and the rubber body of circumference uniform distribution coat supporting element together, prevent that the supporting element inwall from exposing.
The utlity model has following beneficial effect:
1, the sidewall boss the Adhesion force that can increase teflon plate and rubber body, supporting element is set, prevent what teflon plate from coming off;
During 2, with the teflon seal sulfidization molding of sidewall boss, the sidewall boss can make product outer rim rubber body coating consistent from both direction positioning supporting part axially and radially, guarantees the product ovality;
3, all be coated on the rubber body the inside with the supporting element of the teflon seal of sidewall boss, avoid the supporting element inwall to be exposed in air, preventing that supporting element from getting rusty comes into force;
4. all be coated on the rubber body the inside with the supporting element of the teflon seal of sidewall boss, solve that in prior art, the supporting element inwall adheres to the non-uniform rubber body and causes product appearance ugly.
