Description
Technical field
The present invention relates to sealing structure of motor bearing chamber, specially motor big flow thin oil lubricant sealed bearing housing structure.
Background technology
The bearing of half directly-drive permanent magnet wind generating machine and gear-box use same set of oil lubricating system, therefore bearing chamber
Sealing structure turns into one of motor important feature.The sealed bearing housing structure of wind-driven generator includes fixing with electric motor end cap at present
Bearing chamber, bearing Interior Layout is inherently located at the bearing of rotating shaft shaft end, and bearing chamber outer face is fixed with outer bearing cover, on the inside of bearing
Rotating shaft on cover intrinsic internal sealed ring, the inside cap fixed with bearing chamber inner face, inside cap and bearing are cased with internal sealed ring
Between be provided with the oil scraper ring that is placed on internal sealed ring and is fixed on inside cap, the interior cylinder contacted with internal sealed ring of inside cap
Multiple labyrinth seal grooves axially arranged are provided with face, so as to form labyrinth seal structure between inside cap and internal sealed ring.
The mode of labyrinth seal is relied only at present, easily causes the seepage of lubricating oil, and lubricating oil enters motor internal, eventually influences electricity
The insulating properties of machine, reduce the service life of motor.
The content of the invention
The present invention is solved to only rely on the labyrinth seal structure between inside cap and internal sealed ring at present, and big flow thin oil is moistened
A kind of the problem of sliding sealing effectiveness difference, there is provided motor big flow thin oil lubricant sealed bearing housing structure.
The present invention adopts the following technical scheme that realization：Motor big flow thin oil lubricant sealed bearing housing structure, including
Bearing chamber, bearing, outer bearing cover, internal sealed ring, inside cap, oil scraper ring, labyrinth seal is provided between inside cap and internal sealed ring
Structure；Described labyrinth seal structure is step labyrinth structure, the i.e. inner prop of the outer cylinder of internal sealed ring and inside cap
Direction rises and is mutually twisted in ladder from outside to inside in face, extends sealed circuit with this, lubricating oil is dumped into fan
In the seal groove of palace.
Further, the relief hole communicated with any labyrinth seal groove is provided with inside cap, is connected with and lets out on relief hole
Pressure pipe, relief tube are led on the outside of motor, and with this pressure holding in bearing chamber can balance with extraneous, strong prevention lubricating oil
Seepage.
Further, in internal sealed ring and the outer end increase contact seal ring of inside cap contact surface, effectively stop big
Parts of lubricating oil enters in the labyrinth seal groove of inside cap, reduces the pressure of inside cap spill port oil return；Outer bearing cover
Between bearing, between oil scraper ring and bearing, O-ring seal is housed between inside cap and bearing chamber, lubricating oil is prevented
Seepage seals.
Further, the end face outside bottom of the inside cap and position between bearing and inside cap is provided with difference
The oil leak hole communicated with each labyrinth seal groove（Each draining orifice ring circle distribution）；The inner ring bottom of bearing chamber is in the inner part while be provided with
One arc oil-recovery tank, the end face outside of bearing chamber are provided with the outage communicated with arc oil-recovery tank.Inside cap labyrinth seal
Lubricating oil in groove is back to bearing bore through oil leak hole（Space i.e. between inside cap and bearing）, then through oil-recovery tank, oil extraction
Gear-box outside hole backflow stepper motor, so as to form the path of oil return, ensure not accumulate lubricating oil in inside cap.
The present invention is improved by a series of structure, substantially increased close on the basis of existing sealed bearing housing structure
Effect is sealed, so as to by reasonable, novel, unique suitable for big flow thin oil lubricant, its Structure Improvement Design.The present invention is especially suitable
For half directly-drive permanent magnet wind generating machine, it can also be used in other motors.
