Description
Technical field
The present invention relates to high-voltage motor technical fields, are filled more specifically to a kind of high-pressure shaft tile style motor oil-leakage-prevention
It sets.
Background technology
Currently, high pressure bearing shell motor application overhauls convenient and service life in the industrial every field in the whole nation, with it
The advantages that long, obtains the approval of user, but when the operating of bearing shell motor, rotor is the great rotatable parts of rotary inertia, bearing shell
The gas that disc is flowed again after having got rid of the lubricating oil in oil groove is broken up, the thinner small oil droplet mist of oil of formation, while with
The operation of unit, oil temperature and Wa Wen also can be increased accordingly, made to generate positive pressure inside bearing housing, promoted mist of oil with air
Flowing effusion, drains to the outside of unit oil catch.
When existing high pressure bearing shell motor operating, oil ring gets rid of oil and fuel tank internal pressure, and it is poor to form inside and outside oil pressure.When lubricating oil is logical
When crossing sealing ring (labyrinth ring) oil shelves, as soon as being often formed by shrinkage cavity by an oily shelves tooth, primary throttling, oily leakage will produce
Pressure just reduces once, and outer oil shelves room oil pressure is less than previous oily shelves room.And so on, if the oily shelves number of teeth is more, throttle number
More, oil leak amount is also smaller, as soon as and each oily shelves tooth there is inside oil return hole, the oil in each oil shelves to be returned to by oilhole
In bearing housing (watt seat fuel tank), but when leakage rate is more than regurgitant volume, oily shelves just begin to oil leak, influence motor service life.Such as
It is in industry always in the direction of research that, which effectively avoids Leakage,.
Through retrieval, the technological improvement about motor Leakage has existing patent disclosure, such as Chinese Patent Application No.：
2013208739667, the applying date：On December 29th, 2013, invention and created name are：A kind of high-pressure shaft tile style motor oil-leakage-prevention axis
Watt device, this application discloses a kind of high-pressure shaft tile style motor anti-oil-leakage axle bush device, including bearing shell ontology, bearing shell pedestal,
Bearing shell seal assembly and oil chamber, bearing shell ontology are fixed in bearing shell pedestal, the cavity between bearing shell ontology and bearing shell pedestal
For oil chamber, bearing shell seal assembly is fixedly connected on bearing shell pedestal and is equipped with the first oil sealing, and bearing shell device further includes leakproof
Oil seal component, oil-leakage-prevention seal assembly are fixedly connected with bearing shell seal assembly, and the second oil sealing is arranged on oil-leakage-prevention seal assembly.
This application includes the oil-leakage-prevention seal assembly of the second oil sealing in rotor close to the installation of bearing shell seal assembly position, is increased
Critical piece permanent installation and fixed, service life and bearing shell service life can be done with motor primitive axis watt seal assembly
It coexists.But this application only avoids oil leakage phenomenon, practical effect from still having the space that optimization is promoted by adding seal assembly.
