Abstract
The utility model discloses a waveform lip mouth oil seal comprising a ring groove framework, wherein the ring groove framework is provided with flanges facing the inner side and the outer side and internally provided with a rubber seal sleeve; the inner flange and the lower end outer edge of the rubber seal sleeve are connected into a whole by vulcanization; and the oil seal is characterized in that the upper end inner edge of the rubber seal sleeve is provided with a waveform lip mouth. The seal main lip mouth adopts waveform lip mouth to replace the traditional linear lip mouth, thus improving the oil pumping capacity of the lip mouth in high-speed work environmental conditions, reducing the lip mouth contact area, reducing the friction and abrasion, improving the sealing effect in high-speed two-way movement, improving the low temperature performance and service life of the oil seal, and maintaining the full lip mouth lubricating oil film.
Description
Technical field
The utility model relates to running shaft and uses the oil sealing field, is specifically related to a kind of waveform lip oil sealing.
Background technique
At present, domestic what generally adopt is the structure of bidirectional-reflux line, but under the high speed operation environmental conditions, exists the lip temperature too high in order to adapt to the two way sealed requirement of oil sealing, defectives such as pump oil effect deficiency.
The model utility content
The technical problems to be solved in the utility model provides a kind of waveform lip oil sealing, seals main lip and adopts the waveform lip to replace traditional linear lip, improves the pump oil ability of lip under the high speed operation environmental conditions.
For addressing the above problem, the technical solution of the utility model is:
A kind of waveform lip oil sealing, include the ring groove shape skeleton, described ring groove shape skeleton has the flange towards medial and lateral, be provided with rubber sealing boot in the ring groove shape skeleton, the lower end outer edge of the flange of described inboard and rubber sealing boot connects as one by sulfuration, it is characterized in that: the edge is provided with the waveform lip in the upper end of described rubber sealing boot.
The beneficial effects of the utility model:
The main lip of sealing of the present utility model adopts the waveform lip to replace traditional linear lip, improved the pump oil ability of lip under the high speed operation environmental conditions, reduced the lip area of contact, reduced frictional force, wearing and tearing have been reduced, improve the sealing effect that descends bidirectional-movement at a high speed, improved the cryogenic property and the life-span of oil sealing, also kept lip sufficient lubrication oil film simultaneously.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Referring to Fig. 1, a kind of waveform lip oil sealing, include ring groove shape skeleton 1, ring groove shape skeleton 1 has the flange 2,3 towards medial and lateral, be provided with rubber sealing boot 4 in the ring groove shape skeleton 1, inboard flange 2 connects as one by sulfuration with the lower end outer edge of rubber sealing boot 4, and the edge is provided with waveform lip 5 in the upper end of rubber sealing boot 4.
