Abstract
The utility model belongs to the technical field of a sealing element, and particularly relates to a springless waveform lip oil seal. The springless waveform lip oil seal comprises a sealing main lip, a sealing auxiliary lip and a skeleton, wherein the orientation of the sealing main lip is identical to that of the sealing auxiliary lip, both the sealing main lip and the sealing auxiliary lip face towards the bottom of the oil seal, a sealing main edge is set as a wavy-line edge, i.e. the contact place of the sealing main lip and a rotating shaft is in a wavy-line shape. The springless waveform lip oil seal has advantages of good mobility, good sealing effect, long service life and high reliability.
Description
Technical field
The utility model belongs to the Sealing technical field, specifically, relates to a kind of no spring waveform lip oil sealing.
Background technique
Mostly present oil sealing is that the main lip of sealing, sealing pair lip, skeleton and spring combine each other; The mode that it generally adopts forward to install when mounted; When running into special circumstances and need reverse the installation, then it seals main lip anti-lip phenomenon takes place easily, thereby causes oil seal failure; Therefore in addition, existing oil sealing all requires very highly to sealing main lip lip and the running shaft surface Machining precision that is in contact with it and surface quality, causes cost of production very high; In addition, sealing main lip lip and running shaft contacting point is interference fit, then is easy to generate insufficient lubrication or dry grinding phenomenon in air side; Possibly cause the contact position temperature too high, cause the oil sealing material aging life-span to be reduced, thereby cause a serious wear; And its two contact position is the line contact, and the unidirectional return wire pump suction effect of oil sealing is obvious, adopts the bidirectional-reflux line to cancel out each other so that pump is inhaled effect; But effect is limited; For this reason, need a kind of oil sealing that can address the above problem, satisfy the needs of actual conditions.
The model utility content
The utility model provides a kind of no spring waveform lip oil sealing, and it can overcome the existing problem of present oil sealing, has good sealing effect and long working life.
The technological scheme that the utility model adopted is:
No spring waveform lip oil sealing; Comprise sealing main lip, sealing pair lip and skeleton, main lip of said sealing and sealing pair lip towards identical, and all towards the bottom of oil sealing; The main lip lip of said sealing is made as the linear lip of wave, and the contacting point that promptly seals main lip and running shaft is that wave is linear.
In the technological scheme of the utility model, also have following additional technical feature:
The quantity of said sealing pair lip is more than two.
Compared with prior art, the advantage and the good effect of the utility model are: the no spring waveform lip oil sealing of the utility model, it can overcome the existing problem of present oil sealing, has that servo-actuated property is good, good sealing effect, long service life and a high advantage of reliability.
Description of drawings
Below in conjunction with accompanying drawing and mode of execution the utility model is described further:
Fig. 1 is no spring waveform lip oil sealing embodiment 1 structural representation of the utility model;
Fig. 2 is no spring waveform lip oil sealing embodiment 2 structural representations of the utility model.
Among the figure, 1 is the main lip of sealing, and 2 is the sealing pair lip, and 3 is skeleton, and 4 is the linear lip of wave.
Embodiment
As shown in Figure 1; No spring waveform lip oil sealing; Comprise the main lip of sealing 1, sealing pair lip 2 and skeleton 3, main lip 1 of said sealing and sealing pair lip 2 towards identical, and all towards the bottom of oil sealing; The main lip lip of said sealing is made as the linear lip 4 of wave, and the contacting point that promptly seals main lip 1 and running shaft is that wave is linear.
As shown in Figure 2, no spring waveform lip oil sealing, with embodiment 1, different is that the quantity of sealing pair lip 2 is two.
Like this when work; The no spring waveform lip oil sealing of the utility model; It seals main lip 1 and is used to seal solid lubrication fat, and sealing pair lip 2 is used to seal introduced contaminants, through changing the structural type of the main lip lip of sealing; The sealing that is is applicable to reverse installation, and skeleton 3 has played the effect of supporting whole oil sealing; And through increasing the quantity of sealing pair lip 2, can improve the pliability of oil seal lip, make that the servo-actuated property of oil sealing is better, improve the sealing effect of oil sealing; And when oil sealing is installed on the running shaft through interference fit, form the sealing surface with certain width between linear lip 4 of wave and the axle, its width is the amplitude width of the linear lip 4 of wave; Can avoid effectively existing defective to cause leakage of oil on the axle through the linear lip 4 of wave because the main lip lip of sealing is in contact with it; In addition; Sealing lip and running shaft contacting point can form lubricant body, reduce the friction temperature of the main lip lip of sealing, improve the oil sealing life-span; And prevent the wearing and tearing that running shaft causes owing to hardness is lower, the wavelength and the amplitude of the linear lip 4 of wave can form the bidirectional-reflux effect effectively simultaneously.
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)
1. there is not spring waveform lip oil sealing; Comprise sealing main lip (1), sealing pair lip (2) and skeleton (3); It is characterized in that: main lip of said sealing (1) and sealing pair lip (2) towards identical; And all towards the bottom of oil sealing, the main lip lip of said sealing is made as the linear lip of wave (4), and the contacting point that promptly seals main lip (1) and running shaft is that wave is linear.
2. no spring waveform lip oil sealing according to claim 1, it is characterized in that: the quantity of said sealing pair lip (2) is more than two.
