Description

Form is the rotating support mechanism and wind power plant of large-size rolling bearing
Technical field
The utility model is related to the rotating support mechanisms that a kind of form is large-size rolling bearing.The utility model further relates to one Kind wind power plant.
Background technology
Rotating support mechanism has been usually formed machine part or environment division and pedestal in rotation, rack or other solid Transition between fixed motionless machine part or environment division.Rotating support mechanism have for this purpose there are two annular connection Element is connect, one in the two ring-type elements is connected on the part of rotation, another is then connected in fixed bearing On.
What prevalence was very wide herein is so-called rolling bearing, in rolling bearing, rolling element, such as spherical, barrel-shaped, roller The rolling element of shape or taper roller shape rolls in the gap between two annular coupling elements between raceway facing with each other It is dynamic.These rolling elements are dedicated to, with relative motion of the minimum resistance between two coupling elements, it is on the contrary then with maximum The various other relative motion of resistance.
The abrasion of this rolling element can be minimized in the following manner, that is, gap area be equipped with lubricant or with profit Lubrication prescription is filled, particularly lubricating grease or lubricating oil.In order to which this lubricant is maintained in gap area and prevents dirt simultaneously Particle invades, and gap is all sealed on two mouths.
The ring by flexible and/or elastic material is used as the sealer between two coupling elements mostly Part.The shaping sector of this ring has stubbed anchorage zone, and anchorage zone is anchored at one of them of two coupling elements On, also there is the region being tapered, which is passed through narrow sealing lip, and sealing lip is in the area of another corresponding coupling element It sticks on or is collided on thrust surface in domain.
Just thrust surface and on the thrust surface along this contact area between the sealing lip of operation in exist profit The risk of the leakage loss aggravation of lubrication prescription, this is because this region is merely due to the elasticity of flexible and/or elastic sealing material Or the characteristic of reset be closed.If sealing material fatigue or the abrasion aggravation born on a position, then leakage loss is imitated It should continuously increase.
Therefore it has turned to by arranging that tensioning improves sealer with metal wire radially around ground along seal clearance The pressing force of part.The net diameter inside tensioning metal wire being closed in annular can be by becoming along the tensile force around direction It is small, therefore can realize the pressing force being oriented radially inwards.It can be by the area with sealing lip of air locking with this measure Domain is radially inward against to the thrust surface on the coupling element including radial direction.
Mostly using large-size rolling bearing in large-scale technical equipment, they with common rolling bearing difference lies in, It is not by relevant coupling element with the contact of relevant, rotation or fixed machine part or environment division etc. All sides of arching complete, but by the flat end side surface of same coupling element, with reference to screw, bolt or the like Completions are waited, screw, bolt or the like stretch into or extend through the drilling action of the annular spread in relevant coupling element, with Just will connection end side surface firmly and friction lock press to coupling structure.
But to be considered herein, with the increasing diameter of rolling bearing, the arching in gap reduce along its circumferencial direction or The radius of curvature of coupling element is cumulative in the region in gap.But the trend in gap is straight, then is oriented radially inwards The effect that pressing force is sealed with regard to smaller and therefore this tensioning metal wire support in large-size rolling bearing relatively It is small.It also to be supplemented, the tensioning metal wire of corresponding length deforms and therefore cannot be by arbitrarily as tension is cumulative Strong tensioning.
Another viewpoint is that in numerous applications, the part of rotation is supported in fixed part outside. If it is anchored on the coupling element of radial direction outer together with inwardly directed sealing lip in this sealing device, then sealing dress The orientation put in space does not change, because it is anchored on fixed part.
Due to abrasion, the gap of supporting device may become larger at any time, wherein, in external influence factor, such as gravity Under the influence of, occur between fixed and rotation coupling element (although only very slight at the beginning) it is lasting along diameter To relative movement, wherein, the part respectively supported occupies its position as deep as possible.Therefore gap width is in gap circumference It may change on specific position.Such as a heavy axis through rotating support with horizontal longitudinal extension part exists It is moved downward as far as possible under its weight.Gap width then on the most deep position in gap reduce and in gap most Become larger on position above.
If present hermetic unit be anchored at outside, mostly on fixed coupling element, then the sealing Divide and do not surround, but remain constant, and its section on the most deep position in gap for good and all bears radial direction Upsetting pressure and the abrasion therefore born increase, and its section in the region of the top in gap then must for good and all seal change Big gap width.Two kinds of effects have resulted in sealing effect and have become grain.
In addition, this problem especially occurs in the base bearing of wind power plant, base bearing bearing and the wheel hub of wind wheel Connection or the armature spindle being coupled.Because armature spindle is disposed in the rack of machine case, armature spindle couples with built-in Element connects, and external coupling element is then anchored in machine chamber and therefore the vertical orientated of it never changes.
Therefore it is desirable in the case of the base bearing of wind power plant and in some other cases It is that on the coupling element of the rotation including can air locking be anchored at, therefore air locking constantly rotates and it close Envelope lip is not subject to the load of pure static state, and is subject to the load of dynamic change, which results in the sealer in annular The be more uniformly distributed and Anywhere all smaller abrasion in part in the whole circumference of part.But in this case, tensioning is used Metal wire could not ideally improve sealing effect.
Utility model content
The problem of promotion the utility model has been obtained by the defects of illustrated prior art, that is, expand as follows The form that exhibition designs this generic is the rotating support mechanism of large-size rolling bearing, that is, is improved by tension element in sealing lip Pressing force between thrust surface, and be anchored on including radial direction or radial direction outer coupling element with air locking And its sealing lip be collided on the coupling element including radial direction outer or radial direction it is unrelated.
The solution of this problem is reached by the form of the utility model for the rotating support mechanism of large-size rolling bearing It arrives, coupling element of the rotating support mechanism at least two annulars, for coupling each fixed or rotation machine Device part or environment division, wherein, it is obstructed with the contact of relevant, fixed or rotation machine part or environment division The all sides for crossing the arching of relevant coupling element are completed, but the flat end side surface combination screw for passing through same coupling element Or bolt is completed, the screw or bolt stretch into or extend through the drilling of the annular spread in relevant coupling element, so as to will Connection end side surface regularly and friction lock press to coupling structure, wherein, the coupling element can relative to each other surround one The common bearing pivot axis of item, the bearing pivot center is perpendicularly through the base of the coupling element of each annular Face, the rotating support mechanism is also with the bearing clearance between two coupling elements, and the bearing clearance is at least one Annular mouth on circlewise sealed with air locking, wherein, air locking have it is at least one on the mouth of bearing clearance along Extension seals shaping sector made of soft material, and the sealing shaping sector is at least one along the sealing shaping sector The dent of flute profile that longitudinal direction extends, by two slot flanks and a slot bottom limited boundary opposite each other, the dent Depth extension be roughly parallel to bearing pivot center orientation, two slot flanks form sealing shaping sector moulding cross section Two arms inside, they are connected with each other in the region of slot bottom, and wherein one arm is anchored at for will seal shaping sector On the coupling element of annular, and another arm then has the sealing lip for being used for reclining with another coupling element on the outside, Wherein, spring element is inserted into the dent of flute profile, spring element is at least locally sticked on slot flank opposite each other and endeavoured It is therefore first in two connections in the two arms for pressing off these slot flanks each other by its intrinsic spring force and seal shaping sector It is opened each other in the gap of part, thus sealing lip has been obtained to the higher pressing force on its thrust surface.
Therefore the utility model eliminates the drawing with drawbacks described above along the longitudinal direction extension of tensioning metal wire Clamp force, and with opening effect instead of this tightening force, opening acts on unrelated with the radial direction of opposite bearing main shaft.More really It says with cutting, the sealing lip of the anchoring section of annular extension and similary annular extension is opened each other always, is in diameter with sealing lip To be in anchoring section in still in turn be radially in anchoring section outside it is unrelated.Anchoring section is begun by this opening force Final pressure is pressed towards another corresponding coupling element to one of them and sealing lip of two coupling elements.In addition, this opening Effect is related to gap width at most but unrelated with the circumference in gap, thus the pressing between sealing lip and thrust surface is made With will not reduce with the increasing size of bearing.The sealing principle of original creation is therefore particularly suitable for changing in large-size rolling bearing Kind sealing effect.
Special advantage can be realized in the following way, that is, on each coupling element, in the flat of coupling element End side surface in, multiple tapped blind holes are provided with around bearing pivot center annular spread respectively for screwing in each one A screw and/or it is provided with the boring of perforation between two end side surfaces opposite each other of relevant coupling element In being inserted through bolt or screw.Using this interconnection technique can also reliably transmit very big axial force and radial load and Heeling moment, without there are the danger locally overloaded of coupling structure.
The improvement project of the utility model allows for multiple rolling element rows being placed within bearing clearance, passes through the improvement Scheme so that the surface for facing bearing clearance of coupling element is equipped with annular extended flange, and in another coupling element The recess portion of annular extension is provided in the surface of bearing clearance flute profile is faced, it is recessed that annular extended flange may be engaged to this In portion.
Two should be divided into along bearing pivot center by being equipped with that coupling element of the recess portion of annular extension The ring that is stacked of direction.Annular extended flange of the two rings when assembling rotating support mechanism on another coupling element Ground is placed, and is just for example connected to completed coupling element by screw later.
Two flanks of flange are with free end side surface also as two flanks of the recess portion of flute profile respectively can as bottom It is listed on raceway along the raceway of the rolling element of rolling path rolling for use as each one.Different rolling element rows can be by as a result, Axial pressure, axial pulling force and radial load are arranged for, and is optimized for corresponding force component.
Rotating support mechanism according to the present utility model is suitable in a particular manner, and tool is enclosed in as base bearing In the wind power plant for having the wind wheel to rotate about a generally horizontal axis, in order to support the rotor for the wheel hub that carry wind wheel Axis, wherein, the armature spindle of a coupling element and wind power plant connects in anti-relative rotation, and another coupling element and wind The rack of the machine case of power generating equipment connects in anti-relative rotation.
The utility model allows completely or partially to fill out bearing clearance with the lubricant that form is lubricating grease or lubricating oil It fills, lubricant prevents from leaking for a long time by sealing element according to the present utility model.
Special advantage by obtaining as follows, that is, the sealing shaping sector being made of soft material overlaps two completely as follows Bearing clearance between a coupling element, that is, the arm for anchoring for sealing shaping sector is bearing directly against one of annular On coupling element, and the sealing lip sealed on the outside of another arm of shaping sector is bearing directly against the coupling element of another annular On.Due to its soft material property so that sealing shaping sector according to the present utility model can be clung on two coupling elements, And therefore the two sealings opposite simultaneously.The gap of relatively another sealing element or other transition parts are not retained, there It may leak.It designs only by following situation the different cross sections of two arms of sealing shaping sector according to the present utility model Cause, that is, sealing shaping sector be non-rotationally secured on an annular coupling element, however according to two coupling elements it Between relative rotation speed collided on another coupling element.Anchor arm shows as big abutment face with respect to its coupling element, that is, Say the fixation for causing friction lock, and relatively another coupling element of sealing lip only constructs very small, almost linear contact Face, the contact surface hardly cause to rub, and therefore can realize smoothly inswept.
The utility model is it is recommended that the arm for anchoring is bearing directly against with it on the outside of the arm for carrying sealing lip Relevant coupling element is faced in bearing clearance, arching surface region.As being had been carried out above, soft is close This contact of envelope shaping sector is the just also best form of the sealing in the region of anchor arm.
The utility model provides the advantage that, that is, for example when under an applicable cases, the coupling element of axis or inside does not have There is rotation, but when housing or the rotation of the coupling element of outside, it can be bearing directly against internal connection member for the arm of anchoring On part, to meet special seal request.Due to the holddown spring being further described below, sealing lip can also be radially Ground is extruded outward.
In addition in the scope of the utility model, sealing shaping sector be packed into as follows, that is, for anchoring arm with holding The dent for carrying the flute profile between the arm of sealing lip faces bearing clearance.Therefore, it is arranged for opening two arms there , such as the spring element of metal can from externalities well, such as from corrosivity inside bearing clearance Or other modes chemical erosion weather influence dispose.
Sealing shaping sector is then packed into as follows, that is, is made for the arm of anchoring and the arm of carrying sealing lip along sealing The immigration direction extension in type portion.The measure is what there is no problem in the case of by modern tool, is beneficial to higher use Service life, this is because external contamination is not all born in the part of all sensitivities of air locking according to the present utility model;On the contrary Ground there is a possibility that add a kind of curing agent to lubricant, be maintained air locking or the performance of its spring element.
Provided in addition according to the utility model, seal shaping sector for anchoring arm do not have be made of other material The element that carries of work, but thoroughly filled up by the soft material of sealing shaping sector.Exactly in large-size rolling bearing, connection Element bears special mechanical load, and also has the tendency that deforming relative to each other in the case of external loading, as a result, gap Of short duration change may occur for width, may also can especially become larger, at least locally occur.With by by it is other, Perhaps the air locking that the element that the work that also harder material is formed carries is restricted in its deformability is compared, completely by The sealing shaping sector that soft material is formed can correspond to this deformation much betterly.
In addition, sealing shaping sector for anchoring arm should also not with by other material form it is outside, hold The element of load is in contact, but is only contacted with relevant coupling element.Thus, it is possible to spillage risk is reduced in this region To minimum level.
In order to fasten sealing shaping sector, the slot extended in annular can be placed by sealing the arm for anchoring of shaping sector In or in the ditch of bearing clearance.Here, this fastening also has the attached of the also best sealing in the region of anchor arm The additional effect added.
If the arm for anchoring of sealing shaping sector is placed into the ditch of bearing clearance, then the arm can be wherein It is covered by shielding part, and fixed in the ditch for thus narrowing into flute profile by the shielding part.Therefore will not make according to this practicality Novel sealing shaping sector occurs undesirable movement or even unclamps.
Shielding part as used herein can be made of unique, annular part or by multiple, portion in a ring respectively The part of section shape is assembled into.Afterwards kind embodiment be easy to the maintenance under loading state herein so that close to sealing into To be possible, without dismantling rotating support mechanism.
The utility model can improve as follows, that is, seal the bearing clearance and/or bearing clearance in the region of shaping sector Be used for sealing shaping sector for anchoring arm contact surface region in accommodate sealing shaping sector ditch have cylinder Side shape or hollow cylinder-like moulding.In other words, relevant contact surface extends along cylinder week side.This is easy to according to this The loading and dismounting of the sealing shaping sector of utility model.
Exactly in large-size rolling bearing, seal between the arm for being used for anchoring of shaping sector and relevant coupling element Contact surface can have the numerical value of the radius of curvature of 500mm or bigger either have 600mm or bigger radius of curvature or Radius of curvature even with 800mm or bigger or the radius of curvature with 1000mm or bigger.Here, due to special Designing scheme, the pressing force of spring element according to the present utility model is in the region of sealing lip on the one hand due on anchor arm Bearing also not dependent on radius of curvature is always to maintain approximately constant there, that is to say, that even if working as rotating support mechanism also During radius with bigger, the pressing force of this sealing shaping sector does not decline still.
It is relevant in the region for the contact surface between the arm of anchoring and relevant coupling element of sealing shaping sector Coupling element can have the arching portion of convex.This is especially such situation in the coupling element including radial direction, radially The circumferential lateral surface of the convex of coupling element inside faces bearing clearance, and is therefore formed for according to the present utility model close Seal the interior bearing of shaping sector.
It is proved advantageously, slot bottom concavity arching preferably on entire well width of the dent of flute profile.It therefore can be Interior seamed edge is avoided in the region of slot bottom completely and is therefore on the one hand avoided the notch of fatigue of materials is pushed to act on, the opposing party Face can then make spring element better adapt to lasting concave arching portion compared with sharp interior seamed edge.
The width of the dent of flute profile can preferably continuously be improved from slot bottom to notch.This measure can be conducive to spring Element is to the insertion of the dent of flute profile.
By the arm for carrying sealing lip and the arm for being used to anchor of air locking towards notch especially along circular cone side The separation in face can reach this widening towards its notched areas of slot.Therefore maximum that sealing lip is in relevant arm is sudden and violent On the position of dew.
The arm of carrying sealing lip and/or the arm for anchoring of air locking of air locking preferably have in slot bottom and slot The section in the center between mouthful, the section in the center have substantially constant thickness.Therefore arm obtains defined flexural property.
In frame in the utility model, the arm of the carrying sealing lip of air locking is than being used for the arm of anchoring more It is thin.Therefore the arm of carrying sealing lip is significantly more more flexible than anchoring section, therefore produces the pressing force of raising.
Advantageously, the arm of the carrying sealing lip of air locking is smaller than the arm for anchoring.It is accommodating in this way It is ensured in the cavity of air locking, air locking enjoys enough freedom of motion in required bending motion if necessary.
The utility model is recommended, and air locking has in the region of slot bottom away from the flat outside of notch.Due to this The flat outside of kind, air locking can firmly be clamped in ditch by covering device.
There is a possibility that such, that is, there is substantially rectangular or square cross section for the arm of anchoring, have when necessary Angle through chamfering and/or through cavetto, therefore this anchoring section can be with especially along the direction for being parallel to bearing pivot center Bear maximum pressure.
Circle is followed in the central section that the inside for facing slot of arm with sealing lip can be between slot bottom and notch The all sides of cone.In this design, remain for carry sealing lip arm maximum movement leeway.
And the utility model can as follows by extension design, that is, have sealing lip arm away from the outside of slot in addition to institute Stating also has the second sealing lip and/or the contact pin being outwardly oriented outside sealing lip, be substantially molded over correlation in the height of slot bottom Arm on and leave therefrom across bearing clearance towards opposed coupling element direction extension.Therefore it can realize additional Sealing effect.
Other advantages are it follows that is, the second sealing lip and/or contact pin the deviating from towards air locking being outwardly oriented The flat outside of notch obliquely extends.Such as from the overvoltage of bearing clearance in orientation it is possible thereby to by relevant contact pin It firmly presses against on another coupling element.
In addition, the outstanding part of the utility model also resides in, the second sealing lip and/or contact pin outwardly on the one hand With air locking between the flat outside of notch, there are one the dent of acute angle, which preferably carries 60 ° or smaller Subtended angle, particular with 45 ° or smaller subtended angle.Form a lubricant pocket portion in a natural manner there.
Based on the principle by the utility model, spring element is along its longitudinal direction, that is to say, that along the circumference of bearing clearance Direction is not subject to or is subjected only to minimum tightening force.Therefore the principle is fundamentally different from tensioning metal so far Line, these tensionings bear pulling force with circumferencial direction of the metal wire all along bearing clearance.
The advantageous characteristic of the utility model is based on this, that is, spring element transversely bears to compress with its longitudinal direction Power.This principle will generally much, this is because inner ring is faced with sealing lip completely for it or outer ring is unrelated.
In the frame of preferred structure, there are two circumferential area opposite each other, these circumferential areas patches for spring element tool It leans against on each slot flank and each slot flank is pressed based on its intrinsic pretightning force.These circumferential areas are also responsible for making slot side The wing opens each other.
And the utility model can be designed by extension as follows, that is, pressure imports spring with being approximately perpendicular to two slot flanks In element.Therefore shearing force has been avoided as much as it.
Imported into being approximately perpendicular to two slot flanks pressure in spring element preferably substantially with the pivot center of bearing Radially it is directed toward.Therefore sealing lip is forced into always on its thrust surface.
Thus to obtain other advantages, that is, the cross section of two slot flanks opposite each other, the rotation axis wire clamp with bearing Into the smaller angle of basal plane of a ratio and bearing, wherein, pressure is directed in spring element on slot flank.Slot flank Thrust surface therefore is approximately parallel in cross-section, sealing lip is pressed against on thrust surface.
This is based on by the effect of the utility model, that is, the counter-force for sealing lip to be pressed on its thrust surface is not logical What the tightening force for crossing spring element along its longitudinal direction generated, but by the region of the arm for anchoring of air locking The pressure of importing generates.This principle is especially also applied for the large size for having minimum curvature in the region Zhong Zhou sides of bearing clearance Rolling bearing.
A kind of structure provides other advantages, and in this configuration, spring element is by form of wires or linear element It is bent, preferably by the element of metal, is particularly bent by the material of spring such as spring steel or the like.
And the utility model has obtained advantageous extension design as follows, that is, spring element by form of wires or Linear element three-dimensional bending forms.The bending of this three-dimensional has also allowed for spring element to apply in different circumferential areas The pressure being directed toward in opposite direction.
By form of wires or the spring element that forms of linear element bending should have there are one or preferred multiple sections, These sections are in a plane or a plane extends about, the plane with the spacing of very little extend past bearing axis and/ Or opposite bearing axis tilts one angle of very little.This geometry is responsible for making have (anti-) power for staying in intra-segment transmission to exist Extension in the plane of approximate radial.
Another structure regulation shows there are one the spring element tools formed by form of wires or the bending of linear element Or preferably multiple sections, these sections extend via slot bottom directly into another slot flank from a slot flank.Therefore it obtains Connection as short as possible between the side facing with each other of the dent of flute profile, and therefore spring element can use smaller thick stick Stick force generates very big opening force.
In addition, being provided according to the utility model, one (multiple) of spring element extend from a slot flank via slot bottom Section to another slot flank is flatly sticked on each slot flank and is preferably also sticked on slot bottom.It is connect by maximum It touches, the pressing force for fighting the part of the air locking of the elasticity of flexure is minimized and it is anticipated that the material that will not occur in advance is tired Labor.
And to allow for a kind of extension design as follows for the utility model, that is, be bent by form of wires or linear element and Into the one or more of spring element follow up to the section of another slot flank has respectively from a slot flank via slot bottom There are C-shaped or the trend of U-shaped.This geometry approximation corresponds to (interior) cross section of the dent of flute profile.
The utility model is also taught that is bent the two of spring element formed each other by form of wires or linear element Along the circumferencial direction in gap is adjacent, to extend to the section of another slot flank via slot bottom from a slot flank respectively mutual Connection.Thus the adjacent section of spring element is on the one hand kept with the spacing limited, and in addition therefore spring element is combined The component that can easily install single into one.In an ideal scenario, single spring element is along the whole of air locking A (circumference) trend, which is surround, once to be extended.
A kind of arrangement provides other advantages, in this arrangement, is bent by form of wires or linear element Spring element from a slot flank via slot bottom extend to another slot flank center section each end It is connect with each one in two adjacent sections of spring element.Because of the spring element formed by elongated metal wire bending Section tool there are two end and also tool is there are two adjacent spring section, will be in two ends so extremely effective be Each connect with each one in two adjacent sections.
In order between the two of the spring element adjacent sections formed by form of wires or the bending of linear element Connection, the utility model suggested the transition piece or transitional region of arc arching.The connection of this arc can be by elongated Or linear metal wire is made in itself, thus spring element can in its (length of corresponding air locking) whole length By one it is single it is partially complete be made, be made especially by bending.
