Abstract
The utility model relates to a sealing element, particularly to a combined oil seal. The combined oil seal comprises an inner oil seal and an outer oil seal which are mutually combined; and the inner oil seal consists of an inner framework and an inner seal element, and the outer oil seal consists of an outer framework and an outer seal element. The combined oil seal is characterized in that an axial displacement surface is arranged at the contact of the inner framework and the secondary lip of the outer oil seal; and one main lip of the inner oil seal and two secondary lips of the inner oil seal are arranged in the inner seal element. The combined oil seal has excellent dust prevention effect, can prevent dust, sand and mud from entering, avoids the abrasion of the inner lip, prolongs the service life of the oil seal, and meet the requirements of actual condition.
Description
Technical field
The utility model relates to a kind of Sealing, especially a kind of combination oil seal.
Background technique
It is more to be used for automobile sealed combination oil seal structure kind at present, but often all only pay attention to of the sealing of main lip position, and ignored the significance at the dustproof position of air side, therefore the lubricant oil side, the design of dustproof position lip is by formalization, thus the weak link of causing.Like this, at work, sealed axle can axially produce skew, the secondary lip of outer oil seal position can break away from original position, promptly causes axial displacement to produce the gap, makes dust, silt to take advantage of a weak point, in the course of time, these impurity are deposited in interior lip oral area position, thereby cause inner lip wearing and tearing, cause seal failure.For this reason, need a kind of dustproof effect good, prolong the oil sealing oil sealing in working life, satisfy the needs of actual conditions with this.
The model utility content
Combination oil seal of the present utility model, its dustproof effect is good, and dust, silt can not enter, and can not cause inner lip wearing and tearing, have prolonged the working life of oil sealing, can satisfy the needs of actual conditions.
The technological scheme that the utility model adopted is:
Combination oil seal comprises the inner oil seal and the outer oil seal of mutual combination, and inner oil seal is made up of inner frame and interior seal, and outer oil seal is made up of outer skeleton and external sealed body, it is characterized in that: be provided with axial displacement face with the secondary lip touching position of outer oil seal on the inner frame.
Described combination oil seal, interior seal are provided with one inner oil seal master lip and the secondary lip of twice inner oil seal.
Like this when work, combination oil seal of the present utility model, be provided with axial displacement face with the secondary lip touching position of outer oil seal on its inner frame, like this, sealed axle is when axially producing bigger skew, and the secondary lip of outer oil seal position just can not break away from shift surface, dust, silt can not enter yet, thereby avoid causing inner lip wearing and tearing, improved dustproof effect thus, prolonged the oil sealing physical life.
Combination oil seal of the present utility model, its dustproof effect is good, and dust, silt can not enter, and can not cause inner lip wearing and tearing, have prolonged the working life of oil sealing, can satisfy the needs of actual conditions.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and embodiments:
Fig. 1 is original oil seal structure schematic representation;
Fig. 2 is that original oil sealing axial displacement produces the gap schematic representation;
Fig. 3 is the utility model combination oil seal structural representation.
Among the figure, 1 is inner frame, and 2 is interior seal, and 3 is outer skeleton, and 4 is the external sealed body, and 5 is the secondary lip of outer oil seal, and 6 are axial displacement face, and 7 is inner oil seal master lip, and 8 and 9 is the secondary lip of inner oil seal, and 10 is the lubricant oil side, and 11 is air side.
Embodiment
Embodiment
As Fig. 1, Fig. 2 and shown in Figure 3, wherein illustrated in figures 1 and 2 is original oil sealing, it only payes attention to the sealing of main lip position to lubricant oil side 10, and ignored the significance at air side 11 dustproof positions, and sealed axle can axially produce skew, and the secondary lip of outer oil seal 5 positions can break away from original position, promptly cause axial displacement to produce the gap, make dust, silt to take advantage of a weak point, in the course of time, these impurity are deposited in interior lip oral area position, thereby cause inner lip wearing and tearing, cause seal failure.Figure 3 shows that combination oil seal of the present utility model, the inner oil seal and the outer oil seal that comprise mutual combination, inner oil seal is made up of inner frame 1 and interior seal 2, outer oil seal is made up of outer skeleton 3 and external sealed body 4, it is characterized in that: be provided with axial displacement face 6 with secondary lip 5 touching positions of outer oil seal on the inner frame 1; Interior seal 2 is provided with one inner oil seal master lip 7 and the secondary lip 8 and 9 of twice inner oil seal.
Like this when work, combination oil seal of the present utility model, be provided with axial displacement face 6 with secondary lip 5 touching positions of outer oil seal on its inner frame 1, like this, sealed axle is when axially producing bigger skew, and the secondary lip of outer oil seal 5 positions just can not break away from shift surface, dust, silt can not enter yet, thereby avoid causing inner lip wearing and tearing, improved dustproof effect thus, prolonged the oil sealing physical life.
Combination oil seal of the present utility model, its dustproof effect is good, and dust, silt can not enter, and can not cause inner lip wearing and tearing, have prolonged the working life of oil sealing, can satisfy the needs of actual conditions.
Obviously, the foregoing description of the present utility model only is for the utility model example clearly is described, and is not to be qualification to mode of execution of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here can't give exhaustive to all mode of executions.Everyly belong to the row that conspicuous variation that the technical solution of the utility model extends out or change still are in protection domain of the present utility model.
