Abstract
The utility model relates to a sealing part, in particular to a combined oil seal, which comprises an outer oil seal, an inner oil seal and a support ring. The outer oil seal is mutually combined with the inner oil seal. The combined oil seal is characterized in that the outer oil seal is an integral structure consisting of an outer framework, an outer rubber sealing piece and a PTFE (polytetrafluoroethylene) lip, the outer framework, the outer rubber sealing piece and the PTFE lip are directly mounted on the inner oil seal in a vulcanization forming manner, corrugated structures are arranged on the outer oil seal and the inner oil seal, and a lubricating grease layer structure is disposed between the inner oil seal and the outer oil seal. The combined oil seal has the advantages of low cost, simplicity in working procedure, excellent sealing performance and stable sealing effect by means of modifying an original combined oil seal, and can meet requirements of actual conditions.
Description
Technical field
The utility model relates to a kind of Sealing, especially a kind of combination oil seal.
Background technique
Present combination oil seal, mostly be by inner oil seal, outer oil seal and support ring and form, wherein outer oil seal is made up of outer skeleton, outer rubber seal and spring, and the lip of its external sealed rubber body is after sulfuration, prune through finishing process again and form, this lip and inner frame interference fit, but when initial sealing, must inject oil lubrication, otherwise can cause dry friction, influence sealing effect, so it is loaded down with trivial details that it has operation, sealability is relatively poor, the more unsettled defective of sealing effect.For this reason, need a kind of operation simple, favorable sealing property, the combination oil seal that sealing effect is stable satisfies the needs of actual conditions with this.
The model utility content
Combination oil seal of the present utility model, it is by to the improvement of original combination oil seal, and it is low to make it have a cost, and operation is simple, favorable sealing property, the advantage that sealing effect is stable can satisfy the needs of actual conditions.
The technological scheme that the utility model adopted is:
Combination oil seal comprises the outer oil seal and the inner oil seal of mutual combination, and support ring, it is characterized in that: outer oil seal is directly to vulcanize typing by outer skeleton, outer rubber seal and PTFE lip to be installed in integral structure on the inner oil seal.
Described combination oil seal, outer oil seal and inner oil seal are provided with wave structure.
Described combination oil seal is filled with the grease layer structure between inner oil seal and the outer oil seal.
Like this in when work, combination oil seal of the present utility model, outer oil seal are directly to vulcanize typing by outer skeleton, outer rubber seal and PTFE lip to be installed in integral structure on the inner oil seal, and the PTFE lip has good self-lubricating property, need not the lubricant oil of annotating; Need not to mount spring, need not finishing, reduced manufacturing procedure.
Combination oil seal of the present utility model, it is by to the improvement of original combination oil seal, and it is low to make it have a cost, and operation is simple, favorable sealing property, the advantage that sealing effect is stable 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 combination oil seal structural representation;
Fig. 2 is a combination oil seal structural representation of the present utility model.
Among the figure, 1 is outer oil seal, and 2 is inner oil seal, and 3 is outer skeleton, and 4 is spring, and 5 is the outer rubber seal, and 6 is the PTFE lip, and 7 is wave structure, and 8 is the grease layer structure, and 9 is support ring, and 10 is inner frame.
Embodiment
Embodiment
As shown in Figure 1, be original combination oil seal, it is made up of inner oil seal 2, outer oil seal 1 and support ring 9, wherein outer oil seal 1 is made up of outer skeleton 3, outer rubber seal 5 and spring 4, the lip of its external sealed rubber body 5 is after sulfuration, prune through finishing process again and form, this lip and inner frame 10 interference fit, but must inject lubricant oil formation grease layer structure 8 when initial sealing is lubricated, otherwise can cause dry friction, influence sealing effect, so that it has operation is loaded down with trivial details, sealability is relatively poor, the more unsettled defective of sealing effect.As shown in Figure 2, be combination oil seal of the present utility model, the outer oil seal 1 and the inner oil seal 2 that comprise mutual combination, and support ring 9 is characterized in that: outer oil seal 1 be by outer skeleton 3, outer rubber seal 5 and PTFE lip 6 directly the sulfuration typing be installed in integral structure on the inner oil seal 2; Outer oil seal 1 and inner oil seal 2 are provided with wave structure 7; Be filled with grease layer 8 structures between inner oil seal 2 and the outer oil seal 1.
Like this when work, combination oil seal of the present utility model, outer oil seal 1 be by outer skeleton 3, outer rubber seal 5 and PTFE lip 6 directly the sulfuration typing be installed in integral structure on the inner oil seal 2, PTFE lip 6 has good self-lubricating property, need not the lubricant oil of annotating; Need not to mount spring 4, need not finishing, reduced manufacturing procedure.
Combination oil seal of the present utility model, it is by to the improvement of original combination oil seal, and it is low to make it have a cost, and operation is simple, favorable sealing property, the advantage that sealing effect is stable 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.
