Description
Technical field
The present invention relates to a kind of roller bearing, especially relate to a kind of three-row cylindrical roller bearing for directly driven wind generators.
Background technique
At present, main bearing for directly driven wind generators generally adopts the three-row cylindrical roller bearing in inner ring strap bolt hole, the main bearing inner ring is connected on the end face of straight wind dispelling movement axle by bolt, because of arranging a circle bolt hole on the main bearing inner ring, like this, will inevitably increase the thickness of inner ring, and because inner ring all adopts special Bearing Steel to make, so manufacture cost is than higher; In the direct wind-driven generator running, inevitably can produce friction between main bearing retainer and the main bearing Internal and external cycle, because of the main bearing retainer generally is made of metal, so in friction process, can produce some metallic dusts, these metallic dusts tend to sneak in the bearing lubrication medium, and the bearing lubrication medium is very responsive to metal, thus the performance of bearing lubrication medium is reduced, thus influence the working life of bearing.
Summary of the invention
The objective of the invention is to overcome the defective that prior art exists, provide a kind of inner ring not have connecting bolt hole, lightweight three-row cylindrical roller bearing for directly driven wind generators.
The three-row cylindrical roller bearing for directly driven wind generators that provides a kind of retainer and bearing enclose can not wear and tear is provided further aim of the present invention.
The objective of the invention is to be achieved through the following technical solutions: it comprises inner ring, the outer ring, cylindrical roller and retainer, the outer ring is by outer ring I, outer ring II and outer ring III form, the outer ring is provided with at least two through holes, outer ring I, outer ring II and outer ring III are in the same place by the bolton that places through hole, inner ring comprises the inner ring I that directly is enclosed within on the axle, inner ring II, retainer comprises axial cage I, axial cage II, retainer radially, cylindrical roller comprises axial cylindrical roller I, axial cylindrical roller II, cylindrical roller radially, between outer ring III and the inner ring II seal ring I is installed, the pressure plates I of fit sealing circle I is fixed on the III of outer ring, between outer ring I and the inner ring I seal ring II is installed, the pressure plates II of fit sealing circle II is fixed on the I of outer ring, axial cylindrical roller I is installed among the axial cage I, axial cylindrical roller II is installed among the axial cage II, and radially cylindrical roller is installed in radially in the retainer.
Further aim of the present invention is achieved through the following technical solutions: described axial cage I contacts with outer ring I, inner ring I and outer ring II, surface at these contact position axial cage I is a non-planar surface, axial cage II contacts with outer ring III, inner ring II and outer ring II, on the surface of these contact position axial cage II also is non-planar surface, radially retainer contacts with interior I, inner ring II and outer ring II, and radially the surface of retainer also is a non-planar surface in these contact position.
The invention has the beneficial effects as follows:
1, bearing is directly installed on the axle, and bearing inner race needn't be established bolt hole, and bearing inner race need not to link together by bolt and axle, like this, helps alleviating bearing weight, reduces manufacture cost;
2, the bearing axial cage, radially the surface that contacts with bearing enclose of retainer is non-planar surface, helps solving existing three-row cylindrical roller bearing retainer wear problems, guarantees the operation that bearing is safe and reliable.
Description of drawings
Fig. 1 is an embodiment of the invention structural representation;
Fig. 2 is embodiment illustrated in fig. 1 and erection drawing axle;
Embodiment
The invention will be further described below in conjunction with drawings and Examples.
With reference to accompanying drawing, present embodiment comprises inner ring 5, outer ring 3, cylindrical roller 4 and retainer 6, outer ring 3 is by outer ring I3-1, outer ring II3-2 and outer ring III3-3 form, outer ring 3 is provided with two through holes 7, outer ring I3-1, outer ring II3-2 and outer ring III3-3 tighten together by the bolt 10 that places through hole 7, inner ring 5 comprises the inner ring I5-1 that directly is enclosed within on the axle 11, inner ring II5-2, retainer 6 comprises axial cage I6-1, axial cage II6-2, retainer 6-3 radially, cylindrical roller 4 comprises axial cylindrical roller I4-1, axial cylindrical roller II4-2, cylindrical roller 4-3 radially, between outer ring III3-3 and the inner ring II5-2 seal ring I9 is installed, the pressure plates I 8 of fit sealing circle I9 is fixed on the III3-3 of outer ring, between outer ring I3-1 and the inner ring I5-1 seal ring II1 is installed, the pressure plates II 2 of fit sealing circle II1 is fixed on the I3-1 of outer ring, axial cylindrical roller I4-1 is installed among the axial cage I6-1, axial cylindrical roller II4-2 is installed among the axial cage II6-2, and radially cylindrical roller 4-3 is installed in radially among the retainer 6-3.
Axial cage I6-1 contacts with outer ring I3-1, inner ring I5-1 and outer ring II3-2, surface at these contact position axial cage I6-1 is a non-planar surface, thereby help guaranteeing at contact position formation oil film, axial cage I6-1 and race ring are separated, prevent retainer axial cage I6-1 wearing and tearing effectively; Axial cage II6-2 contacts with outer ring III3-3, inner ring II5-2 and outer ring II3-2, surface at these contact position axial cage II6-2 is a non-planar surface, thereby help guaranteeing at contact position formation oil film, axial cage II6-2 and race ring are separated, prevent axial cage II6-2 wearing and tearing effectively; Radially retainer 6-3 contacts with interior I5-1, inner ring II5-2 and outer ring II3-2, radially the surface of retainer 6-3 is a non-planar surface in these contact position, thereby help guaranteeing at contact position formation oil film, make radially that retainer 6-3 and race ring separate, prevent radially retainer 6-3 wearing and tearing effectively.
More than be one embodiment of the present invention, a preferred demonstration example.The scope that patent application of the present invention is asked for protection has more than and is limited to described mode of execution.All and technological scheme present embodiment equivalence all belongs to protection scope of the present invention.
