Abstract
The utility model belongs to the field of sealing elements, and particularly relates to a shaft-mounted combined PTFE structured oil seal, which includes an outer framework and an inner framework as well as a main lip and a secondary lip combined with the outer and the inner frameworks, wherein the main and the secondary lips are combined with a shaft frame, and adopt PTFE sheet structures. The shaft-mounted combined PTFE structured oil seal solves the problems that the existing combined PTFE structured oil seal requires longer processing time and has lower production efficiency, overcomes the defects that the existing combined PTFE structured oil seal has poor radiation performance and is difficult to process and assemble, has the advantages that the working procedure is saved, the production efficiency is high, the production cost is low, the radiation performance is excellent and the eccentricity resistance is excellent, has low requirements for the processing precision of assembling parts, and is easy and convenient to process and assemble.
Description
Technical field
The utility model belongs to the Sealing field, specifically, relates to a kind of from tape spool combined type PTFE structure oil sealing.
Background technique
Mostly the oil sealing of present combined type PTFE structure is to process through vulcanization process, because it needs vulcanization process and post-cure operation, so required process time is longer, manufacturing efficiency is lower; And the oil sealing of this kind combined type PTFE structure is because its rubber body is more, so there is the relatively poor problem of thermal diffusivity; Again because its requirement on machining accuracy to the assembling position is higher, so increased the difficulty of processing and assembling.
The model utility content
It is a kind of from tape spool combined type PTFE structure oil sealing that the utility model provides, and its oil sealing that can solve present combined type PTFE structure is longer its required process time, and the problem that manufacturing efficiency is lower overcomes the big shortcoming of poor radiation and processing and assembling difficulty.
The technological scheme that the utility model adopted is:
From tape spool combined type PTFE structure oil sealing, comprise outer skeleton and inner frame and with the main lip sheet and the secondary lip sheet of its combination, said main lip sheet and secondary lip sheet are also combined with the axle skeleton, said main lip sheet and secondary lip sheet are the PTFE chip architecture.
In the technological scheme of the utility model, also have following additional technical feature:
Also be provided with packing ring between said outer skeleton and the secondary lip sheet.
Said packing ring is the rubber structure packing ring.
Compared with prior art, the advantage and the good effect of the utility model are: the utility model from tape spool combined type PTFE structure oil sealing, its oil sealing that can solve present combined type PTFE structure is longer its required process time; The problem that manufacturing efficiency is lower; Overcome the big shortcoming of poor radiation and processing and assembling difficulty, have the saving operation, manufacturing efficiency is high; Cost of production is low; Thermal diffusivity well reaches the good advantage of anti-eccentric performance, and its requirement on machining accuracy to the assembling position is low, processes and assemble easy and convenient.
Description of drawings
Below in conjunction with accompanying drawing and mode of execution the utility model is described further:
Fig. 1 is that the utility model is from tape spool combined type PTFE structure oil seal structure schematic representation.
Among the figure, 1 is outer skeleton, and 2 is inner frame, and 3 is main lip sheet, and 4 is secondary lip sheet, and 5 is the axle skeleton, and 6 is packing ring.
Embodiment
Embodiment
As shown in Figure 1, from tape spool combined type PTFE structure oil sealing, comprise outer skeleton 1 and inner frame 2 and with the main lip sheet 3 and secondary lip sheet 4 of its combination, said main lip sheet 3 is also combined with axle skeleton 5 with secondary lip sheet 4, said main lip sheet 3 is the PTFE chip architecture with secondary lip sheet 4; Also be provided with packing ring 6 between said outer skeleton 1 and the secondary lip sheet 4; Said packing ring 6 is the rubber structure packing ring.
Like this, the utility model from tape spool combined type PTFE structure oil sealing, it need not vulcanization process, is directly added the main lip sheet 3 and the secondary lip sheet 4 of PTFE structure by inner frame 2, outer skeleton 1 and axle skeleton 5, and the packing ring 6 of rubber structure combines and gets final product.
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.
