Abstract
The utility model provides an OCV (oil control valve) oil seal which comprises a frame, a rubber body arranged on the frame, a spring and a sealing lip. The oil seal is characterized in that the horizontal part of the frame is bent outwards in the axial direction of the oil seal, the bottom part of the sealing lip is connected with the vertical part of the frame, and the spring is vulcanized inside the rubber body at the opening of the sealing lip. The OCV oil seal increases the distance between the inner diameter and the outer diameter of the oil seal and reduces the thickness of the junction of the sealing lip and the frame, thereby realizing the large bias between the axis and the housing of the oil seal; the lip opening encloses the OCV tightly all the time after the assembly of the OCV, so that the oil leakage is prevented; and the spring is vulcanized inside the rubber body at the opening of the sealing lip, the spring is prevented from falling out of the lip opening during the motion of the oil seal.
Description
Technical field
The utility model relates to a kind of Sealing, specifically, is a kind of OCV oil sealing.
Background technique
OCV (hydraulic control valve) oil sealing is a kind of Sealing commonly used in the motor.Existing OCV oil sealing adopts common oil sealing rotary seal structure, the internal diameter of oil sealing and the distance of external diameter are less, make between OCV oil sealing and the OCV can not deflection or deflection ranges less, cause problems such as revealing the motivation body dust of setting out, the difficult installation of OCV in the using process easily, influenced the working life of the sealing of OCV oil sealing.How designing the OCV oil sealing that makes new advances, then is the design problem that the utility model faced.
Summary of the invention
The purpose of this utility model is the deficiency that exists at prior art, and a kind of OCV oil sealing is provided, and can make the OCV that assembles with oil sealing that bigger off-centre is arranged, and adapts to the installation operating mode of OCV fully, more effectively seals.
The purpose of this utility model is achieved by the following technical solution: a kind of OCV oil sealing, comprise skeleton, rubber body, spring and sealing lip attached on the skeleton, described skeleton horizontal component is along the bending of oil sealing radially outward, and the sealing lip bottom is connected the vertical part of described skeleton.
To improvement of the technical scheme: described spring sulfuration is in described sealing lip lip rubber body.
To further improvement in the technical proposal: described skeleton is that the cross section is the iron skeleton of J type.
To further improvement in the technical proposal: described sealing lip bottom is connected the vertical part 1/3-2/5 of described skeleton and highly locates.
To further improvement in the technical proposal: described sealing lip bottom thickness is 1-1.4mm.
The utility model compared with prior art has the following advantages and good effect:
1, the utility model OCV oil tight skeleton horizontal component is designed to along the bending of oil sealing radially outward by of the prior art radially curving inwardly along oil sealing, so increased the distance of OCV oil sealing internal diameter and external diameter, simultaneously, and the sealing lip bottom thickness is less, thereby this part elasticity is increased, during the rotation of engine revolution axle, between the axle of oil sealing and the housing bigger extent of the error can be arranged, the sealing lip lip is tightly held OCV all the time tightly after guaranteeing the OCV assembling, has improved the sealing of OCV oil sealing.
2, spring sulfuration in OCV oil sealing sealing lip lip place makes the lip of oil sealing the phenomenon that spring is deviate from can not take place in movement process in rubber body inside, more effectively guarantees sealing effect.
3, OCV oil sealing iron skeleton intensity is higher, can make oil sealing keep shape and tension force effectively.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in detail.
Fig. 1 is the sectional drawing of the utility model OCV oil sealing along axis;
Fig. 2 is the partial enlarged drawing of I part among the utility model Fig. 1.
Embodiment
Referring to Fig. 1, Fig. 2, a kind of embodiment of OCV oil sealing comprises skeleton 2, attached to the rubber body on the skeleton 21, spring 3 and sealing lip 4.
Skeleton 2 horizontal components are along the bending of OCV oil sealing radially outward, forming the cross section is the iron skeleton of J type, sealing lip 4 bottoms are connected the vertical part of skeleton 2, it is comparatively suitable that connection part is highly located at the vertical part 1/3-2/5 of skeleton 2, sealing lip 4 bottoms and skeleton 2 are connected as a single entity by sulfuration, and sealing lip 4 bottom thickness are 1-1.4mm.
Spring 3 vulcanizes in the rubber body of sealing lip 4 lips, or spring 3 directly is sleeved on the rubber body back side of sealing lip 4 lips
The above, it only is preferred embodiment of the present utility model, be not to be the restriction of the utility model being made other form, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equivalent variations.But every technical solutions of the utility model content that do not break away to any simple modification, equivalent variations and remodeling that above embodiment did, still belongs to the protection domain of technical solutions of the utility model according to technical spirit of the present utility model.
Claims (5)
1. an OCV oil sealing comprises skeleton, the rubber body attached on the skeleton, spring and sealing lip, it is characterized in that: described skeleton horizontal component is along the bending of oil sealing radially outward, and its bottom of described sealing lip is connected the vertical part of described skeleton.
2. according to the described OCV oil sealing of claim 1, it is characterized in that: described spring sulfuration is in described sealing lip lip rubber body.
