Abstract
The utility model belongs to the field of sealing parts and particularly relates to an assembly type oil seal, which comprises an inner oil seal and an outer oil seal. The inner oil seal is formed by combining an inner frame, an inner sealing body and a spring, and the outer oil seal is formed by combining an outer frame and an outer sealing body. The outer oil seal is designed to be in a half-encapsulation structure formed by vulcanization of rubber and the outer frame, a threaded structure is disposed on the outer sealing body, and the direction of the threaded structure is opposite to that of shaft rotation. The outer sealing body of the outer oil seal is designed to be in a structure which combines two modes, one mode is that the diameter of the outer circle of the outer sealing body is equal to the size of the outer frame, and the other mode is that the diameter of the outer circle is larger than the size of the outer frame. A polyurethane dust ring is arranged on the outer sealing body of the outer oil seal. A lubricating grease packing layer is disposed between sealing lips of the inner oil seal. A corrugation structure is arranged at the contact position between the inner sealing body of the inner oil seal and the outer frame. The assembly type oil seal has the advantages of being good in dust prevention effect and sealing performance, simple in processing and low in cost.
Description
Technical field
The utility model belongs to the Sealing field, specifically, relates to a kind of assembling type oil sealing.
Background technique
Present oil sealing adopts inner oil seal and outer oil seal to carry out the structure of simple combination more, and how it need carry out fine finishing or apply sealer; Guarantee the cylindrical sealing of product with this, so there is processed complex in it, the cost problem of higher; And it is not good enough to have dustproof effect, the shortcoming that sealability is relatively poor.
The model utility content
The utility model provides a kind of assembling type oil sealing, and it can solve the existing processed complex of present oil sealing, the cost problem of higher, and it is not good enough to overcome dustproof effect, the shortcoming that sealability is relatively poor.
The technological scheme that the utility model adopted is:
The assembling type oil sealing; Comprise by inner oil seal and outer oil seal; Said inner oil seal is formed by inner frame, interior seal and spring assembly; Said outer oil seal is combined by outer skeleton and external sealed body, and said outer oil seal is made as half rubber-wrapping structure that outer skeleton and the vulcanization of rubber form, and the external sealed body is provided with and the opposite worm structure of axle sense of rotation.
In the technological scheme of the utility model, also have following additional technical feature:
The external sealed body of said outer oil seal is made as the measure-alike and outside diameter of its outside diameter and outer skeleton greater than these two kinds of structures that form is combined of outer skeleton size;
The external sealed body of said outer oil seal is provided with the polyurethane dust ring.
Be provided with the lubricating grease packed layer between the sealing lip of said inner oil seal.
The interior seal of said inner oil seal is provided with ripple struction with outer skeleton touching position.
Compared with prior art, the advantage and the good effect of the utility model are: the assembling type oil sealing of the utility model, and it can solve the existing processed complex of present oil sealing; The cost problem of higher, it is not good enough to overcome dustproof effect, the shortcoming that sealability is relatively poor; Has good dustproof effect; Sealability is good, and processing is simple, advantage with low cost.
Description of drawings
Below in conjunction with accompanying drawing and mode of execution the utility model is described further:
Fig. 1 is original oil seal structure schematic representation;
Fig. 2 is the assembling type oil seal structure schematic representation of the utility model.
Among the figure, 1 is inner frame, and 2 is interior seal, and 3 is spring, and 4 is outer skeleton, and 5 is the external sealed body, and 6 is worm structure, and 7 is the polyurethane dust ring, and 8 is the lubricating grease packed layer.
Embodiment
Embodiment
Be illustrated in figure 1 as original oil sealing; It adopts inner oil seal and outer oil seal to carry out the structure of simple combination, need carry out fine finishing or apply sealer, guarantees the cylindrical sealing of product with this; Therefore there is processed complex in it; The cost problem of higher, and it is not good enough to have dustproof effect, the shortcoming that sealability is relatively poor.Shown in Figure 2 is the assembling type oil sealing of the utility model; Comprise by inner oil seal and outer oil seal; Said inner oil seal is combined to form by inner frame 1, interior seal 2 and spring 3; Said outer oil seal is combined by outer skeleton 4 and external sealed body 5, and said outer oil seal is made as half rubber-wrapping structure that outer skeleton 4 and the vulcanization of rubber form, and external sealed body 5 is provided with and an opposite worm structure 6 of sense of rotation; The external sealed body 5 of said outer oil seal is made as the measure-alike and outside diameter of its outside diameter and outer skeleton 4 greater than these two kinds of structures that form is combined of outer skeleton 4 sizes; The external sealed body 5 of said outer oil seal is provided with polyurethane dust ring 7; Be provided with lubricating grease packed layer 8 between the sealing lip of said inner oil seal; The interior seal 2 and outer skeleton 4 touching positions of said inner oil seal are provided with ripple struction.
Like this when work; The assembling type oil sealing of the utility model; Outer oil seal is made as half rubber-wrapping structure that outer skeleton 4 and the vulcanization of rubber form; And external sealed body 5 is provided with and an axle sense of rotation opposite worm structure 6, makes foreign matter etc. in movement process, be thrown out of, and plays the effect that strengthens dirt exclusion capabilities; Its outer oil seal is made as half rubber-wrapping structure that outer skeleton 4 and the vulcanization of rubber form, thereby the advantages that reliable static sealing ability of rubber elastomer and oil sealing cylindrical metal frame are fixedly positioning is an one, the sealing effect of the excircle part of assurance product; In addition, the external sealed body 5 of outer oil seal is made as the measure-alike and outside diameter of its outside diameter and outer skeleton 4 greater than these two kinds of structures that form is combined of outer skeleton 4 sizes, and it is assembled more easily.
Obviously, the foregoing description of the utility model only be for explain clearly that the utility model does for example, and be not to be qualification to the mode of execution of the utility model.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation or change.Here can't give exhaustive to all mode of executions.Conspicuous variation that every technological scheme that belongs to the utility model is amplified out or change still are in the row of the protection domain of the utility model.
