Abstract
The utility model relates to a sealing element, in particular to a sinusoidal waveform lip oil seal, which comprises a framework, a seal lip and a spring arranged on the seal lip. The sinusoidal waveform lip oil seal is characterized in that the seal lip is in a waveform of a sinusoidal waveform which is axial and symmetrical and has a smooth moulded lip; the diameter of the contact of the lip is a complete circle; the dynamic thermal conduction band of the sinusoidal waveform seal lip is between 0.4 mm and 0.6 mm; and the lower end of the sinusoidal waveform seal lip is provided with one or more dustproof lips. The sinusoidal waveform lip oil seal has the characteristics of good pump suction effect, capability of maintaining fluid dynamic effects, appropriate and reasonable return oil rate, low frictional resistance, good heat dissipation, good sealing effect and prolonged service life of the oil seal, thereby maintaining the stable working of the oil seal and meeting the requirements of the actual situation.
Description
Technical field
The utility model relates to a kind of Sealing, especially a kind of sinusoidal waveform lip oil sealing.
Background technique
The hydrodynamic oil sealing has multiple structural type at present, its air side in the lip part is made shape miscellaneous, as unidirectional many backflow line formulas, two-way broken line backflow line formula and two-way wall scroll wave backflow line formula etc., various forms respectively has characteristics, but under the condition of many dirt, work, the capital sucks dust, perhaps make dust accumulate on the backflow line muscle of projection or the groove between muscle etc. in, oil sealing lost or weaken pump-absorb action.Need for this reason a kind of pump-absorb action effective, can keep suitably rational hydrodynamic oil sealing of hydrodynamic effect, oil return ratio, thereby keep the oil sealing working stability, prolong oil sealing working life, satisfy the needs of actual conditions with this.
The model utility content
A kind of sinusoidal waveform lip oil sealing of the present utility model, it has solved, and work can suck dust under the condition of hydrodynamic oil sealing ubiquitous many dirt commonly used at present, or dust is accumulated on the backflow line muscle of projection or in the groove between muscle etc., thereby lose or weaken the problem of pump-absorb action, it is effective that it has pump-absorb action, can keep hydrodynamic effect, oil return ratio is suitably reasonable, thereby the characteristics that keep the oil sealing working stability, it is low also to have surface friction drag, perfect heat-dissipating, good sealing effect and prolong the oil sealing advantage in working life can satisfy the needs of actual conditions.
The technological scheme that the utility model adopted is:
A kind of sinusoidal waveform lip oil sealing comprises skeleton, sealing lip and the spring that is arranged on the sealing lip, and it is characterized in that: seal lip is made as the wave-like of axial symmetrical sine waveform, and it has level and smooth mold pressing lip, and lip contacting point diameter is a full circle.
Described a kind of sinusoidal waveform lip oil sealing, the dynamic transmission of heat band of its sinusoidal waveform seal lip is 0.4mm-0.6mm.
Described a kind of sinusoidal waveform lip oil sealing, its lower end, sinusoidal waveform seal lip position is provided with one or more dustproof lips.
Like this in when work, a kind of sinusoidal waveform lip oil sealing of the present utility model, its seal lip is just at axial undulate, and its lip contacting point diameter remains a full circle, and regardless of the sense of rotation of axle, it can both play pump-absorb action; When axle rotated, whole contact zones or dynamic transmission of heat band were all wetting night by oil; Wherein air side angle fluid particle quilt is on one side got back to the oil pocket side angle again on one side along the circumference erasing; And the fluid particle of oil pocket side is pressed to the scraping on the sword of the steep angle of oily side lip in a circumferential direction, and then is swept and go in the oil back chamber; Like this, dynamically the transmission of heat region is increased, the about 0.13-0.25mm of Static Contact bandwidth of general oil sealing, though and the contact bandwidth of sinusoidal waveform lip structure has only increased about 2%, but dynamically the transmission of heat band has increased by 200%, the raising of heat dissipation potential makes the temperature under the lip descend, thereby oil viscosity improves; Because thicker oil film is arranged, surface friction drag is lowered again, makes that temperature rise reduces under the lip, thereby has prolonged the working life of oil sealing.

Description of drawings
The utility model is described in further detail below in conjunction with drawings and embodiments:
Fig. 1 is embodiment's 1 structural representation;
Fig. 2 is embodiment's 2 structural representations.
Among the figure, 1 is skeleton, and 2 is seal lip, and 3 is spring, and 4 is sinusoidal waveform, and 5 is dynamic transmission of heat band, and 6 are dustproof lip.
Embodiment
Embodiment 1
As shown in Figure 1, a kind of sinusoidal waveform lip oil sealing comprises skeleton 1, seal lip 2 and the spring 3 that is arranged on the seal lip 2, its seal lip 2 is made as the wave-like of axial symmetrical sine waveform 4, and it has level and smooth mold pressing lip, and lip contacting point diameter is a full circle; The dynamic transmission of heat band 5 of its sinusoidal waveform seal lip is 0.4mm-0.6mm.
Like this in when work, a kind of sinusoidal waveform lip oil sealing of the present utility model, its seal lip 2 is just at axial undulate, and its lip contacting point diameter remains a full circle, and regardless of the sense of rotation of axle, it can both play pump-absorb action; When axle rotated, whole contact zones or dynamic transmission of heat band 5 were all wetting night by oil; Wherein air side angle fluid particle quilt is on one side got back to the oil pocket side angle again on one side along the circumference erasing; And the fluid particle of oil pocket side is pressed to the scraping on the sword of the steep angle of oily side lip in a circumferential direction, and then is swept and go in the oil back chamber; Like this, dynamically transmission of heat band 5 zones are increased, the about 0.13-0.25mm of Static Contact bandwidth of general oil sealing, though and the contact bandwidth of sinusoidal waveform lip structure has only increased about 2%, but dynamically transmission of heat band 5 has increased by 200%, the raising of heat dissipation potential makes the temperature under the lip descend, thereby oil viscosity improves; Because thicker oil film is arranged, surface friction drag is lowered again, makes that temperature rise reduces under the lip, thereby has prolonged the working life of oil sealing.
Embodiment 2
As shown in Figure 2, a kind of sinusoidal waveform lip oil sealing, with embodiment 1, different is that its lower end, sinusoidal waveform 4 seal lips, 2 position is provided with two dustproof lips 6.
A kind of sinusoidal waveform lip oil sealing of the present utility model, it has solved, and work can suck dust under the condition of hydrodynamic oil sealing ubiquitous many dirt commonly used at present, or dust is accumulated on the backflow line muscle of projection or in the groove between muscle etc., thereby lose or weaken the problem of pump-absorb action, it is effective that it has pump-absorb action, can keep hydrodynamic effect, oil return ratio is suitably reasonable, thereby the characteristics that keep the oil sealing working stability, it is low also to have surface friction drag, perfect heat-dissipating, good sealing effect and prolong the oil sealing advantage in working life can satisfy the needs of actual conditions.
