Description

Combined double-lip oil seal

Technical Field

The utility model relates to an oil blanket technical field especially relates to a modular lips oil blanket.

Background

The oil seal is a mechanical element for sealing oil, and separates a part needing lubrication in a transmission part from a force-applying part, so that the lubricating oil is prevented from leaking.

As shown in fig. 1, it is a schematic structural diagram of an oil seal with a conventional structure, in which an inner circular dynamic sealing lip and a shaft generate a holding force under the action of a spring, and in addition, a pumping effect of the oil seal itself can play a role of a sealing medium. However, since the inner circle of the oil seal with the conventional structure has only one dynamic seal lip, it can only seal one medium, and the sealing effect is poor, and thus, a solution is urgently needed.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to the above-mentioned problem, a modular lips oil blanket is provided to solve traditional structure oil blanket and only can seal a medium, sealed relatively poor problem of effect.

The utility model aims at realizing through the following technical scheme:

the utility model provides a modular double lip oil blanket, includes the oil blanket body, the oil blanket body includes symmetrical arrangement's first skeleton, second skeleton, the cladding has first rubber body on the first skeleton, the inboard one end of first rubber body is provided with first seal lip, just it has first spring groove to open on the first rubber body, first spring inslot is installed and is used for making the first spring that first seal lip inwards tightened up, the cladding has the second rubber body on the second skeleton, the inboard one end of second rubber body is provided with second seal lip, just it has second spring groove to open on the second rubber body, second spring inslot is installed and is used for making the second spring that second seal lip inwards tightened up, first rubber body with second rubber body joint is connected.

As an optimized scheme of the utility model, it has the draw-in groove to open on the first rubber body, be provided with on the second rubber body with the pothook of draw-in groove looks adaptation.

As an optimized scheme of the utility model, the bore of the notch of draw-in groove is steadilyd decrease from inside to outside in proper order.

As an optimized proposal of the utility model, a vent groove is arranged at the joint of the first rubber body and the second rubber body.

As an optimized scheme of the utility model, first rubber body all be provided with wavy static seal arch on the second rubber body.

The beneficial effects of the utility model are that, a modular lips oil blanket adopts the lips structure, and it can seal two kinds of different media simultaneously to have sealed effectual characteristics, and first rubber body, second rubber body joint are connected, convenient assembling, simple.

Detailed Description

The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings. It is to be understood that the embodiments described herein are merely illustrative of the present invention and are not limiting thereof.

Referring to fig. 2, fig. 2 is a schematic structural view of a combined double-lip oil seal.

In this embodiment, a combined double-lip oil seal includes an oil seal body, the oil seal body includes a first framework 1 and a second framework 2 which are symmetrically arranged, the first framework 1 is coated with a first rubber body 3, one end of the inner side of the first rubber body 3 is provided with a first sealing lip 4, and a first spring groove is arranged on the first rubber body 3, a first spring 5 for inwards tightening the first sealing lip 4 is arranged in the first spring groove, a second rubber body 6 is coated on the second framework 2, a second sealing lip 7 is arranged at one end of the inner side of the second rubber body 6, and a second spring groove is formed in the second rubber body 6, a second spring 8 used for enabling the second sealing lip 7 to be tightened inwards is installed in the second spring groove, and the first rubber body 3 is connected with the second rubber body 6 in a clamping mode.

Specifically, in this embodiment, a clamping groove 9 is formed on the first rubber body 3, and a clamping hook 10 adapted to the clamping groove 9 is arranged on the second rubber body 6.

In order to ensure the connection reliability of the first rubber body 3 and the second rubber body 6, in this embodiment, the aperture of the notch of the clamping groove 9 decreases gradually from inside to outside.

In order to avoid vacuum formation in the space between the first sealing lip 4 and the second sealing lip 7, in this embodiment, a vent groove 11 is formed at the joint between the first rubber body 3 and the second rubber body 6.

In order to improve the sealing effect, in this embodiment, the first rubber body 3 and the second rubber body 6 are both provided with a wavy static sealing protrusion.

Above-mentioned modular lips oil blanket adopts the lips structure, and it can seal two kinds of different media simultaneously to have sealed effectual characteristics, and first rubber body 3, the 6 joint of the second rubber body are connected, convenient assembling, simple.

The above embodiments have been merely illustrative of the basic principles and features of the present invention, and the present invention is not limited by the above embodiments, and does not depart from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims.
