Abstract
The utility model relates to a main bearing for wind power generation, belonging to the filed of a wind driven generator. The main bearing is characterized by comprising an upper outer ring of the main bearing, a lower outer ring of the main bearing, a thrust cylindrical roller and a retainer; the inner sides of an inner ring of the main bearing and the lower outer ring of the main bearing are respectively provided with two rows of thrust cylindrical rolls; the outer side of the inner ring of the main bearing is provided with a single row of radial and cylindrical rollers; and the cylindrical rollers are arranged on the retainer. The utility model reduces a main shaft, can greatly reduce the impact of the original rigid shaft to a gear box and a power generator, prolongs the service life of the gear box and the power generator, better realizes the transmission of force, is easy to maintain and disassembly, can bear large-load axial force and larger radial load, can better adapt the working condition of the wind driven generator without the main shaft, and meets the force requirements thereof.
Description
One, technical field
The utility model relates to a kind of main bearing for wind power generation, belongs to the wind-driven generator field.
Two, background technique
At present, known the wind-driven generator structure of gear-box is arranged is that main bearing places in the main bearing seat, and main bearing seat is fixedlyed connected with the cabin base plate, and main shaft one end is connected with wheel hub, and the other end is connected with gear-box by main bearing seat, and gear-box links to each other with generator.Be rigidly connected on this structure, main shaft is very big to the impact of gear-box and generator, easily causes gear-box to damage ahead of time, and repair demolition is got up extremely inconvenient.
Three, summary of the invention
The purpose of this utility model has in a kind of impact that reduces gear-box and generator is provided, and gear-box is difficult for damaging ahead of time, the main bearing for wind power generation of maintenance, convenient disassembly.
Technical solution: the present invention includes: outer ring, thrust cylindrical roller, retainer under outer ring, the main bearing on the main bearing, the main bearing inner ring, the inboard, outer ring is provided with two row thrust cylindrical rollers under the main bearing, the outside of main bearing inner ring is provided with the single-row centripetal cylindrical roller, and cylindrical roller places on the retainer.
Be equipped with oil hole on the sidewall of outer ring under outer ring and the main bearing on the main bearing.
On the main bearing under the top of outer ring and the main bearing bottom of outer ring be provided with oil sealing.
On the main bearing under outer ring and the main bearing outer ring tighten together by socket head screw.
On the main bearing under outer ring and the main bearing outer ring be provided with through hole.
The main bearing inner ring is provided with through hole.
Advantage of the present utility model:
1, the outer ring of main bearing links to each other with the cabin, inner ring and wheel hub are fixed, wheel hub passes main bearing and is connected with the coupling that is flexible coupling, the coupling gear-box that is flexible coupling connects, the benefit of this structure: the one, cut main shaft, the 2nd, can reduce of the impact of former stiff shaft greatly to gear-box and generator, prolonged the working life of gear-box and generator, and the transmission of realizable force well, for ease of maintenaince dismounting.
2, from the performance of main bearing, it is thrust main bearing and the entad combination of main bearing, and inboard, outer ring two is classified the thrust cylindrical roller as, can bear big load axial force.The inner ring outside is the single-row centripetal cylindrical roller, also can bear bigger radial load.Both combinations can adapt to the operating mode of this kind dereliction axis wind power generator well, satisfy its force request.
Four, description of drawings
Fig. 1 is the utility model structural representation.
Five, embodiment
11 inboards, outer ring are provided with under the utility model main bearing, following two row thrust cylindrical roller 5 and thrust cylindrical rollers 9, the outside of main bearing inner ring 12 is provided with single-row centripetal cylindrical roller 2, cylindrical roller 2 places on the retainer 8, retainer 10 is placed on the interior step of outer ring 11 under the main bearing, thrust cylindrical roller 9 is placed in the roller position of retainer 10, main bearing inner ring 12 is placed in the interior ring of main bearing outer ring 11, be placed with retainer 8 in the outside of main bearing inner ring 12, single-row centripetal cylindrical roller 2 is placed on the retainer 8, be positioned on the step of main bearing outer ring 11 of retainer 8 belows and place retainer 6, thrust cylindrical roller 5 is placed in the roller position of retainer 6, on the main bearing under outer ring 1 and the main bearing outer ring 11 tighten together by socket head screw 7.
Be equipped with oil hole 3 on the main bearing under outer ring 1 and the main bearing on the sidewall of outer ring 11.
On the main bearing under the top of outer ring 1 and the main bearing bottom of outer ring 11 be provided with oil sealing 4.
On the main bearing under outer ring 1 and the main bearing outer ring 11 be provided with through hole 13.
Main bearing inner ring 12 is provided with through hole 14.
When using the utility model, only need the main bearing outer ring is connected with the cabin by through hole 13, main bearing inner ring 12 passes through through hole 14 and is connected with wheel hub and gets final product.
