Abstract
The utility model belongs to the technical field of sealing, and particularly relates to a pressure-resistant oil seal, which comprises a skeleton, a spring and a rubber sealing body which are mutually combined, wherein the rubber sealing body is provided with a main sealing lip and an auxiliary sealing lip, and the auxiliary sealing lip is provided with a groove shaped like the Chinese character 'JI'. According to the utility model, the problem that the existing pressure-resistant oil seal has poorer following property can be solved; the defect that an eccentric wear or oil leakage phenomenon is easily caused can be overcome; the main sealing lip adopts a thick and solid structure for sealing under higher pressure resistant working conditions; and the structure of the groove shaped like the Chinese character 'JI' of the auxiliary sealing lip provides a deformation space for the auxiliary sealing lip, so that the capability of the auxiliary sealing lip to follow a shaft can be ensured under the condition of guaranteeing eccentricity or swinging. The pressure-resistant oil seal disclosed by the utility model has the advantages that the following property is good, and the eccentric wear or oil leakage phenomenon is not easily caused.
Description
Technical field
The utility model belongs to technical field of sealing technology, specifically, relates to a kind of withstand voltage oil sealing.
Background technique
Present withstand voltage oil sealing is for bearing required pressure; The seal lip of its product is designed to the structure of sturdy abundant type more; Though this oil sealing can bear stronger pressure, for the existing pressure of sealing operating mode, when seal shaft has off-centre or circular runout big again; Will produce the inclined to one side or oil leakage phenomenon of mill, so there is the problem of the servo-actuated poor-performing of withstand voltage oil sealing in it.
The model utility content
The utility model provides a kind of withstand voltage oil sealing, and the problem that it can solve the present existing servo-actuated poor-performing of withstand voltage oil sealing overcomes to be easy to generate and grinds partially or the shortcoming of oil leakage phenomenon.
The technological scheme that the utility model adopted is:
A kind of withstand voltage oil sealing comprises skeleton, spring and the rubbery sealed body of mutual combination, and said rubbery sealed body is provided with primary seal lip and secondary seal lip, and said secondary seal lip place is provided with several font grooves.
In the technological scheme of the utility model, also have following additional technical feature:
The quantity of said primary seal lip and secondary sealing lip is two or more.
Compared with prior art, the advantage and the good effect of the utility model are: a kind of withstand voltage oil sealing of the utility model, and it can solve the problem of the present existing servo-actuated poor-performing of withstand voltage oil sealing; Overcome to be easy to generate and grind partially or the shortcoming of oil leakage phenomenon; Its primary seal lip place adopts thick thick solid structure, in order to the sealing of anti-elevated pressures operating mode, and the structure of several font grooves at its secondary seal lip place; For secondary seal lip provides deformation space; Under the situation that guarantees the eccentric of axle or swing, secondary seal lip is with the follow-up capability of axle, and it has the advantage that servo-actuated is functional and be difficult for eccentric wear or leakage of oil.
Description of drawings
Below in conjunction with accompanying drawing and mode of execution the utility model is described further:
Fig. 1 is original withstand voltage oil seal structure schematic representation;
Fig. 2 is a kind of withstand voltage oil seal structure schematic representation of the utility model.
Among the figure, 1 is skeleton, and 2 is rubbery sealed body, and 3 is spring, and 4 is the primary seal lip, and 5 is secondary seal lip, and 6 is several font grooves.
Embodiment
Embodiment
As shown in Figure 1; Be the withstand voltage oil sealing of original structure, its seal lip is designed to the structure of sturdy abundant type more, though this oil sealing can bear stronger pressure; But for the existing pressure of sealing operating mode; When seal shaft has off-centre or circular runout big again, will produce the inclined to one side or oil leakage phenomenon of mill, so there is the problem of the servo-actuated poor-performing of withstand voltage oil sealing in it.Shown in Figure 2 is a kind of withstand voltage oil sealing of the utility model, comprises skeleton 1, spring 3 and the rubbery sealed body 2 of mutual combination, and said rubbery sealed body 2 is provided with primary seal lip 4 and secondary seal lip 5, and said secondary seal lip 5 places are provided with several font grooves 6.
Like this in when work, a kind of withstand voltage oil sealing of the utility model, its primary seal lip 4 places adopt thick thick solid structure; Sealing in order to anti-elevated pressures operating mode; The structure of several font grooves 6 at its secondary seal lip 5 places is for secondary seal lip 5 provides deformation space, under the situation that guarantees the eccentric of axle or swing; Secondary seal lip 5 is with the follow-up capability of axle, and it has the advantage that servo-actuated is functional and be difficult for eccentric wear or leakage of oil.
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.
Claims (2)
