Between band union elbow and pipe joint, locking nut is set.The utility model patent gives a kind of oil extraction knot of large-size machine
Structure, but no bearing scrapes fat function.
204013030 U of Chinese patent CN disclose a kind of half directly-drive permanent magnet wind generating machine bearing lubricating system, end cap
Position between on the inside of the bearing lateral surface and bearing end cover forms oil scraper ring, and oil sealing and disc, disc are installed in rotating shaft
Space and oil scraper ring between forms waste oil passing away.204442073 U of Chinese patent CN disclose a kind of high-voltage motor
Disc structure, arranges disc and oil scraper ring between bearing and bearing end cover, oil scraper ring is pressed on bearing by bearing end cover
On the end face of end face or end cap, that 1.5mm ~ 2.5mm is left between the inner ring and disc of oil scraper ring gets rid of oil-gap.The two are public
Bearing that the patent of cloth is related to row's fat structure, relies on disc or disc is lubricated the discharge of fat, but actually due to
The restriction of structure, oil-throwing performance are limited, and row's fat effect is undesirable, the high problem of bearing temperature usually occurs.
The content of the invention
The present invention be directed to above-mentioned technical problem, there is provided a kind of simple structure, it is convenient for installation and maintenance, with excellent row's fat
The preferable novel bearing of function, radiating effect arranges fat structure.
The present invention is solution above-mentioned technical problem, there is provided technical scheme below：A kind of novel bearing arranges fat structure, including
It is installed on end cap on the bearing in rotating shaft, bearing, the inner cap of bearing both sides and enclosing cover, it is characterised in that positioned near enclosing cover side
Vane type row's alicyclic ring is equipped with, vane type row's alicyclic ring includes the collar affixed with rotating shaft, the grease disk for being arranged at collar periphery, encloses
Around the uniform blade of set ring center, blade side is connected with grease disk card, and outer interior surface offers groove, groove and bearing
Between constitute lubricating grease cavity, grease disk and blade are located in lubricating grease cavity, and in enclosing cover lower sidewalls, the row's of offering fat hole, right
Grease Collection box should be installed in the position in row's fat hole.
Preferably, the collar that rotating shaft arranges alicyclic ring with vane type is screw thread cooperation spinning, the collar is located on the outside of enclosing cover and opens
Several removal holes are provided with, removal hole inward turning connecting bolt is pressed closer in rotating shaft.The collar of vane type row's alicyclic ring and rotating shaft can also
Using taper fit or the installation form of interference fit.
Preferably, maze trough is offered on grease disk, maze trough connects sealing with the inside bulge loop of enclosing cover centre bore.
Preferably, 3 ~ 8mm of distance between blade outermost and enclosing cover groove inner bottom surface, forms one and gets rid of oil-gap.
Preferably, the collar and grease disk and blade are bulk metal cast structure or overall steel part and processing or adopting
Welding structure.
Preferably, vane type row's alicyclic ring arranges different blade quantities and blade pitch angle.
Preferably, Grease Collection box can be used being bolted on bearing end cover, it would however also be possible to employ be bolted to
On end cap.
For above-mentioned technical proposal is explained further, the operation principle of the present invention is described in detail below：Using the electricity of lubricating grease
Machine bearing, periodically needs to carry out grease-added maintenance work.Because lubricating grease is added with a cycle, with motor bearings
Operating, the waste and old lubricating grease in bearing should be excluded in time, but the lubricating grease of addition of being looked for novelty can not be lost in again it is too fast.Adopt for this
A kind of new bearing row's fat structure, i.e., in the side of bearing end cover, be provided with vane type row's alicyclic ring, vane type row's alicyclic ring, axle
Hold enclosing cover and waste oil collecting box constitutes row's fat structure of complete set.Vane type arranges alicyclic ring by the collar, grease disk, blade, fan
Palace groove and removal hole are constituted；The cylindrical circumferential directions of the collar have blade, and when motor rotates, blade rotation produces good
Fat function is got rid of, while also producing certain blast, plays a part of cooling bearing.Stay and bearing end cover between grease disk is cylindrical
3 ~ 8mm's or so goes out fat gap, and grease disk forms guarantor's fat cavity with bearing side so that the lubricating grease of new addition will not mistake
Flow out soon.
Beneficial effect of the present invention：1st, bearing row fat simple structure, is coordinated using screw thread between vane type row's alicyclic ring and rotating shaft,
Easy installation and removal.2nd, as vane type row's alicyclic ring is provided with blade, when blade is rotated with rotating shaft, good gets rid of oily effect, solution
The problem that waste and old grease of having determined easily is piled up and can not got rid of.3rd, when vane type row alicyclic ring rotates, blade drives air flow, moreover it is possible to
The effect of bearing radiating is played enough.In a word, using new row's fat structure, the waste and old lubricating grease of bearing can not only be made easily to arrange
Go out, and the temperature control of dynamo bearing can be made in comparatively ideal level, efficiently solve existing wind turbine shaft
Hold the high long-standing problem of temperature.
