Description
Technical field
The utility model is related to a kind of magnetic coupling for being equipped with oil sealing.
Background technology
The outer bearing on magnetic coupling does not have oil sealing in the prior art, with working long hours, is lubricated at outer bearing
Oil can be through in gland slot leakage to recirculated cooling water, the leakage of one side lubricating oil can cause the mill of magnetic coupling rotating shaft
Damage, reduce the service life of magnetic coupling, on the other hand can also cause the pollution of recirculated cooling water, be unfavorable for recirculated cooling water
Recycling.
Utility model content
The utility model aims to overcome that above-mentioned the deficiencies in the prior art, and there is provided a kind of magnetic couple for being equipped with oil sealing
Device, can effectively prevent oil leak, improve magnetic coupling service life, will not Pollution Cycle cooling water, it is more environmentally-friendly.
The technical solution of the utility model is：A kind of magnetic coupling for being equipped with oil sealing, the magnetic coupling is provided with
Outer bearing, the outer bearing is provided with gland, and the inner ring of the gland is provided with an oil sealing, the oil sealing by supporter, skeleton,
Primary seal lip, spring, the first secondary sealing lip and the second secondary sealing lip composition, the skeleton is coated in the supporter, described
First secondary sealing lip, primary seal lip and the second secondary sealing lip are connected in turn on the supporter from top to bottom, and described first is secondary
The bottom of the top of sealing lip and the outer bearing keeps certain gap, and the bottom of the first secondary sealing lip is to supporter side
To gradually tapering up, the spring, which is arranged on the outside of the primary seal lip, the gland, is additionally provided with multiple through holes, and described second
Secondary sealing lip is arranged at below the gland and is connected by connecting pole through the through hole with the supporter in bowl-shape, institute
The outside for stating supporter is provided with irregular ripple glaze, and the inwall of the gland inner ring is corresponding with the ripple glaze provided with one
Groove, the supporter is connected in the inner ring.
Further, the gland is thickening gland.
Further, the supporter, the primary seal lip, the first secondary sealing lip, the second secondary sealing lip and
The connecting pole is formed in one structure.
Specifically, the skeleton is entwined by elastic wire.
The beneficial effects of the utility model are：Gland of the present utility model is provided with oil sealing, and oil sealing is provided with three rings in not
With the inclined sealing lip of angle, oil leak can be effectively prevented, magnetic coupling service life is effectively improved, will not pollute and follow
Ring cooling water, it is more environmentally-friendly.
