Description
Technical field
The present invention relates to a kind of rolling bearing arrangement, preferably has 0.5m or more than the large-size rolling bearing of the diameter of 0.5m, for example particularly in the category of wind blade bearing structure, be used to be rotationally connected, this rolling bearing arrangement has two ring-type elements of being provided with alternately of region-type concentrically and at least each other, be used to be connected respectively above of two equipments unit that can reverse relatively, and has a gap between these connecting element, thereby they can be looped around the center of annular connecting element, with vertical substantially relative the reversing of axis of imaginaries of planar annular, wherein, be provided with at least two row's rolling elements in the gap area between connecting element.
Background technique
Large-size rolling bearing, just the diameter bearing of starting at from about 0.5m is often bearing strong especially power or moment vertical with its reference level, that just can not bear under its indeformable situation under many applicable cases.In this case, for example also can expect for example excavator of construction vehicle, wherein, rotating vehicle cab is connected with vehicle frame by large-size rolling bearing and supports bucket simultaneously, must be received by large-size rolling bearing when traction or lifting load thereby act on top power.Yet large-size rolling bearing bears stronger load when using on wind energy facility.For example, rotor blade is connected with wheel hub by each large-size rolling bearing usually, adjusts so that can tackle it mutually with wind-force.When wind-force intensity is constant substantially in time, so this adjustment do not change-and blade bearing does not reverse, though blade-section bears very large wind-force load.When receiving this load, the distortion of the circle of bearing, but be not that two circles similarly are out of shape, but be out of shape according to different modes.For example, the pure axial load of bearing with bearing angle commonly used of 35 °-70 ° has just caused the radial component of the load on rolling element., because being out of shape, shrinks with the while inner ring by rolling element at this so between two circles, form the outer ring hole enlargement.Under complicated more load condition, wherein except axial load, also occur radially and/or the tilting moment load, the distortion of Yin Faing can present this situation thus, promptly for example the outer ring becomes ellipse and inner ring is same is out of shape ovally, but wherein two ellipses stagger each other with 90 °.This strong deformation itself is brought a series of major defect: on the one hand, they cause friction torque significantly to rise, because rolling element must be out of shape when any rotational motion of rolling bearing and this external lubricant is squeezed on overladen rolling element, thereby lubricating film fracture there, this situation why occurring, is because this large-size rolling bearing bears load when out of service through being everlasting.On the other hand, the severe deformation of the circle on the stuffing box bearing itself causes very strong suction movement under the situation of alternately loading, make oiling agent bear very strong local compression, and consequence is to increase leakage.Under its situation about adding up, this disadvantageous effect causes reducing the working life of this large-size rolling bearing, and so not only owing to relevant therewith spare part cost, but also because shutting down of impaired equipment all causes the cost that can't neglect.
Summary of the invention
These defectives from the prior art introduced, generation causes problem of the present invention, to rolling bearing, the so further formation of large-size rolling bearing particularly, even so that under disadvantageous load condition, just on the one hand in the rate of reversing very low or even when common shutting down, might be under often roughly the same torsion angle, and on the other hand under the situation of very strong axial load, radial load and/or tilting moment load, make the maximization in working life of rolling bearing.
The solution of this problem is achieved thus, be that annular connecting element is completely or partially overlapped diametrically, and one or more raceway of rolling element is arranged on annular connecting element radially in the overlapping areas like this, make the connecting line between the center of point of contact of rolling element and two raceway be equal to, or greater than 75 ° with respect to the bearing angle that planar annular surrounded, for example be equal to, or greater than 80 °, preferably be equal to, or greater than 85 °, particularly be equal to, or greater than 88 ° or be similar to and be called " rolling element row " below the lucky 90 °-this rolling element row with big bear angle; And the bearing angle of (in addition) one row rolling element is 15 ° or littler wherein at least, for example 10 ° or littler, preferred 5 ° or littler, particularly is called " the rolling element row with little support angle " below 2 ° or the littler-this rolling element row.
The present invention is made up of a plurality of steps in view of the above: at first produce a radially overlapping areas between two connecting element, this point is unusual for the large-size rolling bearing with the fastener rings (inner ring and outer ring) that radially is provided with alternately; This overlap region is used for bearing angle is brought up to about 90 ° numerical value then.Need consider whole raceway geometrical shapies at this.Usually the rolling element raceway be slightly larger than the radius of spheroid transverse to the measured arch radius of rotating direction, thereby produce the definite contact area that almost is point-like.By the central point of two raceway cross sections and the relative position of spheroid, can predesignate bearing angle: if these central points roughly in the axial direction, just the rotation axis with rolling element staggers abreast each other, but in the opposite direction, just a common cross sectional planes inside, the central spot of bottom raceway is above the raceway central point of top, these central points launch a connecting line so, if this spheroid passes this relevant cross section plane just, the central point of spheroid roughly is on its middle zone.If this connecting line is just or approximately be parallel to the bearing rotation axis, (connecting line is corresponding with respect to angle and the bearing angle of the reference level of rolling bearing), axial force is transmitted not producing under the situation that makes the radial force component that circle is out of shape by race ring so.This point also is applicable to and the fully corresponding tilting moment of asymmetric axial load.Because the common plane of rolling bearing circle is connected with machine assembly or apparatus assembly closely and add reinforcing at this on it is axial, so they are to the common relative insensitivity of pure axial load.Therefore adopt this measure can obviously reduce the distortion of mutual coilable race ring.Rolling element row with little support angle is mainly used in to transmit radial force or be used for two connecting element and centers mutually.But at this, 15 ° bearing angle is a higher extreme value; Definite says, preferred bearing angle is 0 °, just less than 5 ° or even less than 2 °.The influence of outer radial power and the influence of outside axial force are separated, that is to say, outer radial power does not produce inner axial force on this bearing and outside axial force does not produce inner radial power.
Fact proved that advantageously an annular connecting element has at least one annular region towards another connecting element, wherein, its at least one side equally by another connecting element at least region-type around.This side forms radially overlapping areas jointly in the zone of the same side surrounding of this and another connecting element, and the possibility of bringing is, at least one row's rolling element is set in this zone, and the bearing angle of rolling element can be adjusted to such an extent that be substantially equal to 90 °.
Because can only transmit axial force on the pressure direction by the only simple overlapping areas between the connecting element that can reverse toward each other, so the present invention is designed in the category of further formation of the present invention, annular connecting element has at least one annular region in the face of another connecting element, two sides of this annular connecting element by another connecting element at least region-type ground around.Utilize zone and two dual folding that the side is overlapping of a this connecting element, at least two row's rolling elements can be set, so that both can also can on direction of pull, transmit axial force on the pressure direction.
At least one of a connecting element can constitute the annular flange flange of protruding to the direction of another connecting element diametrically by another connecting element separately in the annular region of side surrounding, thereby needn't be on the whole around relevant circle, but only be looped around it along pencil part with the axial height that reduces in the face of distributing on the shell side of bearing play, although thereby (part) is radially overlapping in the zone of this pencil part, but bearing in the axial direction, just vertical with its reference level total height needn't be selected greater than having the traditional bearing that can compare physical dimension.
The present invention is designed in addition, and one or more quilts of at least one flange constitute the one or more raceways that are used for rolling element around the side.Therefore utilization of the present invention promptly can be provided with radially overlapping each other raceway by the radially overlapping possibility that produces, so that rolling element can be with almost 90 ° bearing angle running.
The present invention can following further formation, promptly is provided with to be used at least one raceway of another row's rolling element at least at least one flange distolateral.These additional rolling elements that are somebody's turn to do the row of adding roll between two raceways of connecting element in view of the above, process also on two shell surfaces opposite each other of raceway in the zone of annular space and stagger to each other about the rolling bearing rotation axis diametrically in view of the above.Therefore rolling bearing row that should be additional can transmit the radial force between the circle, thereby the bearing of equipping this rolling bearing row is applicable to thinkable all load conditions.
In category of the present invention, annular connecting element has the roughly cross section of C shape, comprises at least two annular regions in the face of another connecting element, is extended with the zone of another connecting element therebetween in the space.Because the geometrical shape of this cross section, this connecting element can be on two sides around the annular flange flange of another connecting element and therefore constitute dual overlapping.Because two overlap regions have the minute surface symmetrical structure about the reference level of the approximate mid-section of relevant rolling bearing in this case,, transmit on axially at two by its pressure so realize a kind of following bearing setting.
The present invention is designed to for this reason, on the internal surface that faces with each other of the connecting element with C shape cross section, particularly is provided for each raceway of row's rolling element on the side that its elevated regions faces with each other.The quilt of each self-forming of these raceways and another connecting element is around the symmetric body of each raceway on the flange.They have quilt with first connecting element around the corresponding therewith identical cross-sectional geometry of raceway on the flange as symmetric body.
The present invention allows following further formation in addition, promptly has to be provided with at least one in the zone of at least one depressed part between two elevated regions of connecting element of C shape cross section and to be used for the raceway of another row's rolling element at least.This raceway is as using with the quilt of another connecting element symmetric body around the additional raceway on flange distolateral; Therefore this raceway preferably is on the bottom of the groove-shaped depression portion of annular spread between two elevated regions.As symmetric body it have with another connecting element on the corresponding therewith identical cross-sectional geometry of additional raceway.
The assembling of two chimeric alternately connecting element becomes easily thus, and the annular connecting element individual pen that be separated from each other by at least two, that stack mutually that promptly preferably has C shape cross section is formed.Have thus C shape cross section connecting element two halves or individual pen can temporarily be separated from each other and then another connecting element is carried out from both sides re-assemblying around ground, pack at the same time when needing and for example carry out under the situation by the common rolling element row who keeps of each retainer.
In category of the present invention, the connecting element with C shape cross section is diametrically in inside and/or externally around another connecting element.As following also to introduce, this have both sides-just not only in inner radial but also externally (about the rotation axis of bearing) by around the bearing structure of connecting element be significant especially.
Therefore overlapping width w radially should make rolling element not bear shear load greater than rolling element diametrically about half extension of reversing axis of rolling bearing.Under the situation of spherical rolling element, this design code have with radially overlapping width greater than the equal meaning of the radius of a ball.Radially the preferred value of overlapping width is about 1.5 times of the radius of a ball or is higher than this value.
Total should be provided with at least two row's rolling elements, and it staggers in the axial direction each other.As long as the raceway that is used for these two rolling element rows on two connecting element is provided with symmetrically with respect to the reference level minute surface of the approximate mid-section of rolling element, just by row's rolling element transmission, another row's rolling element then is responsible for the axial pressure on the opposite direction to axial pressure on direction.
The present invention is characterised in that at least two row's rolling elements in addition, and it has respectively do for oneself 75 ° or bigger bearing angle, for example 80 ° or bigger, is preferably 85 ° or bigger, particularly 88 ° or bigger.According to this big bear angle, these rolling elements row can transmit axial force, and does not produce excessive radial force at this.But at this, 75 ° bearing angle is considered as minimum limiting value; Preferred bearing angle is 90 °, just on the one hand at 85 ° or even between 88 °, on the other hand until 90 °.
Rolling element with big bear angle can constitute spheroid, and these spheroids and its raceway constitute the contact area that almost is point-like, thus radially overlapping width can select less than rolling element diametrically about the extension of rolling bearing rotation axis.Because under the rolling element situation of roll forming or (slightly) taper, the contact area constitutes linearly and extends by the whole length of roller in the ideal case, and described this rolling element does not allow the corresponding shortening of overlapping width.
Rolling element with little support angle can roll forming ground, taper ground or tubular or spherically constitute because in this linear contact area with the parallel distribution of the rotation axis of rolling bearing and therefore radially overlapping width is not influenced.
Fact proved that advantageously the rolling element that at least one row has a little support angle is arranged on two rows in the axial direction to have between the rolling element at big bear angle.For the reason of stability, the interior flange of slot-shaped gap that stretches into the annular of another connecting element has certain minimum and extends on the direction parallel with the rolling bearing rotation axis.Therefore the free end face of this flange has certain minimum width.Therefore be suitable for this position is used to additional rolling bearing row is installed, keep so that the general construction height of bearing is able to lowland.
This additional row's the rolling element with little support angle can roughly be on the height of connecting element segmentation place with C shape cross section, thereby these rolling elements can be packed into when assembling without difficulty.
In category of the present invention, connecting element is passed toward each other in the axial direction and/or is constituted like this, so that a connecting element is distolateral, for example outer connecting element is distolateral protruding on the bottom side of rolling bearing, in contrast, another connecting element distolateral, for example radially built-in connecting element distolateral projection on opposed bottom side.Therefore this rolling bearing can directly insert between two apparatus assemblies that can reverse toward each other and/or parallel to each other, the smooth face of machine assembly, and need not to be provided with special structure on these assemblies, because each annular connecting element only is close on one of two apparatus assemblies and/or machine assembly then.
The invention provides the possibility that bearing constitutes like this, promptly on the bottom side of rolling bearing, Tu Qi connecting element distolateral overlaps the distolateral of another connecting element diametrically fully there.Reach by this measure that bearing is distolateral not to have a bearing play, particularly by an annular connecting element fully around another connecting element on the rolling bearing bottom side.
In addition, if annular connecting element inner radial and radially outer, just both sides are all around another connecting element, the mouth of two bearing playes all is laid in the zone of a common bearing face jointly so, thereby forms open-and-shut especially relation.
By further following this design code, no matter be both sides by around the radially built-in shell surface of connecting element on or on its radially external shell surface, be equipped with separately a annular region in the face of another connecting element, by around connecting element each free another connecting element of two sides at least region-type around.The every pair of side respect to one another can receive or transmit axial force and/or tilting moment on the both direction separately, thereby can realize a kind of multiple raising that has, the bearing of for example double load carrying capacity by this measure.
Both sides by around connecting element the side by around annular region inwardly can constitute on the one hand radially and on the other hand radially outward to both sides carry out around the annular flange flange protruded of connecting element.Thus both sides by around connecting element obtain T shape or
Shape or+cross section of shape, wherein, two ends of the crossbeam of this cross section element by both sides carry out around connecting element around.
What have advantage especially is, both sides carry out around and/or both sides by around connecting element (respectively) have cross section about the axis of symmetry symmetry parallel with the rotation axis of bearing.This measure is under the outside situation identical with inner separately half partly geometrical shape separately, and the power of assurance is evenly distributed on the inside of race ring, thereby need not to worry the local excess load of bearing region.Therefore the structure height of bearing is minimized.
The present invention suggestion, both sides carry out around and both sides by around connecting element between the gap in be provided with at least each two pairs and arrange about middle the reference level of the bearing rolling element at big bear angle that has separately opposite each other.Therefore both sides by around two flanges of element be used for power transmission and transmission of torque equally.
Another advantage is that another row has the rolling element at big bear angle at least, itself and both sides by around the junction surface of connecting element distribute opposed to each other.Therefore the transmission that can further improve axial pressure at least.
The present invention is characterised in that in addition at least one row has the rolling element at little support angle, its along both sides by around the radially built-in and/or radially external distolateral distribution of connecting element.Particularly be optimized because have the rolling element row at big bear angle for the transmission of axial force and/or tilting moment, thus recommendable be another rolling element row, it can also transmit radial force at least in limited scope.Can be spheroid or roller according to design at this; Simultaneously its diameter according to load condition can less than, be equal to, or greater than the diameter of rolling element substantially with big bear angle.
For rolling bearing being fixed on the equipment unit that can reverse toward each other, connecting element should have the hole of the poroid configuration of screw thread, is used to hold clamping bolt.Large-size rolling bearing can only utilize a large amount of machine bolts to fix, so that on the one hand transmit axial tension and produce enough normal force on the other hand, is used for constituting the connection that rubs between rolling bearing and equipment unit that is connected or machine part.Fastener hole can constitute through hole, thereby machine bolt perhaps can be tapped blind hole by nut or the locking of other threaded piece, and wherein, clamping bolt directly is fixed in the hole so.When the fastener hole of connecting element constitutes the blind hole that is provided with internal thread, in both sides, just not only on its radially built-in shell surface but also on its external circumference shell surface all by around the installation of connecting element become easy.
Gap between two connecting element can be sealed on two bottom sides of rolling bearing, preferably by the connecting element of a projection and separately between another connecting element at least respectively seal ring in the zone of stepped part seal.Different requirements is satisfied in this sealing: make rolling element and the raceway of contamination particle away from sensitivity on the one hand; Prevent the oiling agent discharge on the other hand.Therefore preferred sealed gap can be filled with oiling agent between two connecting element, particularly with grease-filled.So sealed cavity between two connecting element not only can be partly but also can be most of or even utilize oiling agent to fill fully.If one or two Sealings constitute like this, make its reliably sealing under the situation that pressure inwardly points to, in contrast, when the Overpressure of a safety valve threshold value, seal ring is opened under the situation that pressure outwards points to, so with new grease when being pressed in the sealed cavity for grease fitting that this was provided with, the lubricant grease of use can be discharged by this Sealing, thereby any dismounting that need not bearing just can be carried out supplemental lubrication or the additional grease of annotating.
Last according to principle of the present invention, the shell side away from common gap of at least one connecting element is provided with engaging piece.Therefore the possibility of opening up simultaneously is, torsion angle between two connecting element is predesignated definitely by transmission device, wherein, transmission shaft connects with the connecting element of engagement by this base part with the engaging piece engagement such as at least one small gear, worm screw, and the shell of transmission component preferably is fixed on another connecting element or is fixed on connected machine part or the equipment unit.

Embodiment
The rolling bearing 1 of Fig. 1 comprises the element 2,3 of two annulars, is used to be connected respectively above of two equipments unit that can reverse toward each other and/or machine part.Two connecting element 2,3 have different mean radiuss.Therefore possible is that connecting element 2,3 can roughly be arranged on the common plane like this, makes the connecting element 2 with small radii be in the inside that has than the connecting element 3 of long radius.Below therefore also can abbreviate inner ring 2 and outer ring 3 as.

In the footpath of the shell surface 4 of inner ring 2 to the outside, outer ring 3 is connected beyond the rolling bearing gap 11 with its built-in shell surface 5.The upper-end surface 12 of this shell surface 5 and outer ring 3 and with its lower end surface 13 looping seamed edge 14,15 separately.This annular seamed edge line 14,15 is in preferred roughly the same radius r
2, i, maxDown around the rolling bearing rotation axis.And wherein shell surface 5 radially to interior on the direction of rolling bearing rotation axis projection or form the ligule lug boss 16 of annular.This lug boss 16 is in the inside of groove-shaped depression portion 10, because the latter's cross section is greater than lug boss 16.Radially farthest the built-in separating surface 17 of annular relief 16 is along radius r
2, i, minCylindrical shell distribute.Because lug boss 16 embeds in the depressed part 10, be suitable for:

Rolling bearing 1 has total three row's rolling elements.Therefore have three raceways above each of two annular connecting element 2,3 separately, one is used for each rolling element row separately.These three raceways are arranged on the inside of annular recess 10 on inner ring 2, on the outer ring they all be in the annular lug boss 16 on.
The depressed part 10 of the shell surface 4 of inner ring 2 has the channel shape cross-section of band shape bottom surface 18, the distribution of bottom surface 18 roughly can be by being similar to rolling bearing rotation axis cylindrical shell face concentrically, and having two sides that are connected with bottom surface 18 19,20, it finally leads to the upper curtate or the lower curtate of shell surface 4.These sides 19,20 are formed for the raceway of each row's rolling element 21,22, and the 3rd raceway 23 that is used for the 3rd row's rolling element 24 then is in the bottom 18 of groove-shaped depression portion 10.Respectively as with the symmetric body of two first raceways 19,20 be one of two sides 25,26 of the annular relief 16 of outer ring 3, the corresponding portion of the 3rd raceway 23 then is on the separating surface 17 of lug boss 16.
Therefore between each side 25,26 of the lug boss 16 on each side 19,20 that is in the depressed part 10 in the shell surface 4 of inner ring 2 and the internal valve is each row's rolling element 21,22, and rolling element 21,22 constitutes spheroid and has preferably identical separately radius r
