  • Sealing With Elastic Sealing Lips (AREA)

Abstract

The utility model provides a rotatory oil blanket of area oil seal lip, the technical problem that solve is: the inner ring of the existing oil seal is provided with a main oil sealing surface and a dust sealing lip which are respectively used for sealing oil and dust. Therefore, the main oil seal surface is under oil pressure. After a long time, the main seal oil is deformed, the sealing effect is reduced, and even the sealing function is lost. The utility model has the following main points: and an oil sealing lip is arranged on the other side of the main oil sealing surface. The utility model has the advantages that: because the oil sealing lip is added, the pressure of the main oil sealing surface is reduced, the service life of the main oil sealing surface is prolonged, and a sealing measure is added, so that the sealing effect is improved.

Description

The rotary oil seal of band oil-sealing mouth
Technical field
The utility model relates on a kind of end face that is installed in the mechanical rotation axle, prevent a kind of seal arrangement of oil leak.
Background technique
The said oil sealing of the utility model is widely used in the motor of automobile, and it is installed on the end face of mechanical rotation axle, prevents that lubricant oil with pressure is to external leakage.A primary seal pasta 2 and envelope dirt lip 1 are arranged on its interior ring of present oil sealing, be respectively applied for oil sealing and seal dirt (referring to Fig. 1).Therefore the primary seal pasta is to be in work under the oil pressure.Time one is long, and oil pressure can make the distortion of primary seal oil, reduces sealing effect, even loses sealing function.
Summary of the invention
The purpose of this utility model is to provide the rotary oil seal of the band oil-sealing mouth of a kind of long service life, good sealing effect.
A primary seal pasta and envelope dirt lip are arranged on the ring in the purpose of this utility model is achieved in that, it is characterized in that: the opposite side at the primary seal pasta also has an oil-sealing mouth.First function of oil-sealing mouth is to bear oil pressure, and second function is to implement the sealing of first road.
The utility model is compared with the prior art scheme, owing to increased oil-sealing mouth, has alleviated the pressure of primary seal pasta pressurized, has prolonged the working life of primary seal pasta, and has increased seal approach one, has improved sealing effect.
Description of drawings
Further specify the utility model below in conjunction with accompanying drawing.
Fig. 1 is the plan view of existing oil sealing.
Fig. 2 is the sectional view of Fig. 1 along the A-A line.
Fig. 3 is a plan view of the present utility model.
Fig. 4 is the portion view of Fig. 3 along the B-B line.
Embodiment
Referring to Fig. 3,4, a primary seal pasta 2 and envelope dirt lip 1 are arranged on the ring within it, it is characterized in that: the opposite side at the primary seal pasta also has an oil-sealing mouth 3.First function of oil-sealing mouth is to bear oil pressure, and second function is to implement the sealing of first road.
