Accompanying drawing explanation
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings:
Fig. 1 is the structural representation of high-powered engine bent axle PTFE combination oil seal of the present utility model.
In figure, 1 is outer oil seal, and 2 is seal, and 3 for supporting lip, and 4 is dust excluder lips, and 5 is PTFE lips, and 6 is inner frame.
Detailed description of the invention
In order to be more fully understood that this utility model, below in conjunction with specific embodiment, this utility model is explained in detail.But,
Obviously this utility model can be carried out different modification and remodeling and broader without departing from this utility model of appended claims
Spirit and scope.Therefore, following example have exemplary and do not have conditional implication.
Embodiment:
A kind of high-powered engine bent axle PTFE polytetrafluoroethylcombination combination oil sealing, as it is shown in figure 1, include outer oil seal 1, outer oil seal
1 is combined with seal 2, and the bottom of seal 2 is provided with support lip 3, and the side of seal 2 is provided with dust excluder lips 4, seal
2 be arranged above with PTFE lips 5, the side of seal 2 be provided with support lip 3, dust excluder lips 4 and PTFE lips 5 contacts
Inner frame 6.
In the above-described embodiments, inner frame 6 is set to instead " L " font.
In the above-described embodiments, the top of inner frame 6 is provided with lateral part.
In the above-described embodiments, the position that the lateral part at inner frame 6 top is connected with inner frame 6 side is provided with medial sulcus
Groove.
In the above-described embodiments, outer oil seal 1 is set to " L " font.
In the above-described embodiments, the bottom of the outer oil seal 1 of " L " font is provided with the bossing of "U" shaped.
