Abstract
The invention discloses a bearing housing at a main transmission end of a super power wind driven generator, which is in a double bearing structure. A deep groove ball bearing and a cylindrical roller bearing are sequentially sleeved on a rotary shaft. The outer rings of the deep groove ball bearing and the cylindrical roller bearing are sleeved with transmission end covers, and a shaft extension end bearing fixing plate is connected between the outer ring of the deep groove ball bearing and the transmission end cover. A bearing inner cover is installed on one side of the cylindrical roller bearing, and a bearing outer cover is installed on one side of the deep groove ball bearing. An oil flinger is installed between the bearing outer cover and the rotary shaft. The oil flinger is sleeved on the rotary shaft, and a gap is reversed between the oil flinger and the outer cover of the rotary shaft. The bearing housing at the main transmission end of the super power wind driven generator provided by the invention has the characteristics that the double bearing structure is adopted, and the structural characteristics and work characteristics of the cylindrical roller bearing and the deep groove ball bearing are adequately utilized, so that the large load of the main transmission end of the super power wind driven generator is shared to the maximum extent; and the gap between the oil flinger and the bearing outer cover is reserved to discharge residual lubricating grease, so that the heating problem caused by accumulation of much grease in the bearing housing is effectively avoided.
Description
Technical field
The invention belongs to the generator designs field, be specifically related to a kind of super high power wind driven generator principal driving end bearing chamber.
Background technology
Fragile, the problems such as bearing temperature is high, motor holding shaft of bearing roller that existing super high power wind-driven generator exists always.
Summary of the invention
The object of the invention is to overcome above-mentioned not enough problem, a kind of super high power wind driven generator principal driving end bearing chamber is provided.
The technical scheme that the present invention adopts for achieving the above object is: super high power wind driven generator principal driving end bearing chamber, adopt dual bearing structure, namely in rotating shaft, be set with successively a deep groove ball bearing and a cylinder roller bearing, the outer ring sleeve of described deep groove ball bearing and cylinder roller bearing is equipped with the driving end end cap, and be connected with shaft extension end bearing fixed head between described deep groove ball bearing outer ring and the driving end end cap, described cylinder roller bearing one side is equipped with internal bearing cover, and described cylinder roller bearing, seal by bearing seal ring between internal bearing cover and the rotating shaft three, described deep groove ball bearing one side is equipped with bearing end cover, between described bearing end cover and the rotating shaft disc is installed, described disc is sleeved in the rotating shaft, and and the rotating shaft enclosing cover between leave the space.
The bearing chamber of described cylinder roller bearing one side adopts H7 level tolerance, and the bearing chamber of described deep groove ball bearing one side adopts large matched in clearance, namely leaves the gap between described deep groove ball bearing and the driving end end cap, makes deep groove ball bearing be vacant state in bearing chamber.
Characteristics of the present invention are: adopt dual bearing structure, take full advantage of design feature and the operating characteristic of cylinder roller bearing and deep groove ball bearing, shared to greatest extent the large load of super high power wind driven generator principal driving end; And by the space between disc and the bearing end cover unnecessary lubricating grease is discharged, thereby effectively avoided the heating problem that is in High Rotation Speed and needs in the situation lower bearing room of frequent supplemental lubrication fat too much grease gathering to cause when bearing.

Embodiment
Shown in Fig. 1-5, the present invention adopts dual bearing structure, namely in rotating shaft, be set with successively a deep groove ball bearing 4 and a cylinder roller bearing 5, the outer ring sleeve of described deep groove ball bearing 4 and cylinder roller bearing 5 is equipped with driving end end cap 6, the bearing chamber of described cylinder roller bearing 5 one sides adopts H7 level tolerance, the outer ring of cylinder roller bearing 5 can well be contacted with the inner ring of driving end end cap 6, be applied to the radial load of bearing arrangement to bear generator itself and unit gearbox, and because the design feature of cylinder roller bearing 5 itself, make it not bear axial force, the bearing chamber of described deep groove ball bearing 4 one sides adopts large matched in clearance, it is the radially monolateral 1mm of leaving gap between the inner ring of the outer ring of described deep groove ball bearing 4 and driving end end cap 6, make deep groove ball bearing 4 in bearing chamber, be vacant state, complete bearing radial force not, and because the design feature of deep groove ball bearing 4 itself, it is shared in whole main transmission end bearing structure bears by motor self electromagnetism power and unit to tilt and the axial force of generation, be connected with shaft extension end bearing fixed head 3 between described deep groove ball bearing 4 outer rings and the driving end end cap 6, with the fixing relative position of deep groove ball bearing 4 outer rings and driving end end cap 6 in a circumferential direction, thereby prevent that the bearing outer ring that the reason owing to large gap causes from rotating the bearing heating problem that causes with rotating shaft, described cylinder roller bearing 5 one sides are equipped with internal bearing cover 8, and described cylinder roller bearing 5, seal by bearing seal ring 7 between internal bearing cover 8 and the rotating shaft three, described deep groove ball bearing 4 one sides are equipped with bearing end cover 2, between described bearing end cover 2 and the rotating shaft disc 1 is installed, described disc 1 is sleeved in the rotating shaft, and and leave a narrow space between the rotating shaft enclosing cover 2, when generator operation, unnecessary lubricating grease is because centrifugal action is thrown in the space that forms between disc 1 and the bearing end cover 2 by disc 1, and be discharged to outside the bearing chamber by the outage that is positioned at bearing end cover 2 bottoms, thereby avoided in the bearing chamber too much grease to assemble the heating problem that causes.
The above; only be the better embodiment of the present invention; but protection scope of the present invention is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to replacement or change according to technical scheme of the present invention and inventive concept thereof, all should be encompassed within protection scope of the present invention.
