Description
The present invention relates to the apparatus and method of the assembly for Non-Destructive Testing with the rolling bearing of multiple rolling body.
Rolling bearing has inner ring and outer shroud, and it is by rolling body, and such as spheroid, right cylinder or cone are separated from each other.Rolling body is placed in retainer usually
in, to remain on the constant distance between rolling body.When rolling bearing moves, rolling body rotates in inner ring, namely in rolling bearing, running face is rotated, and rotates on outer shroud, namely rotates on the outer running face of rolling bearing.Inner ring and outer shroud and described running face are made up of hardened steel usually, to ensure the little and long service life of the pivoting friction of rolling bearing.
In order to detect the assembly of rolling bearing, particularly this type of running face, such as known, and before installation rolling bearing, check its fault, such as, difference in hardness, these differences may produce in the fabrication process.If rolling bearing has assembled and installed, then no longer with known testing tool, it may be detected, this is because described assembly is not easy to enter in the mounted state.Therefore must obtain and first dismantle rolling bearing, such as to reach running face, this needs a large amount of time and cost is higher.
Such as known from DE4128807A1, by one or more sensor, such as electromagnetic high-frequency coil, be arranged between rolling body and be arranged in the web (Steg) of rolling bearing retainer, object is to identify and the damage of monitoring on the running face of the bearing collar or on adjacent area.
DE102008018611A1 describes a kind of measurement mechanism, have the scan-probe (Abtastspitze) be arranged on bending unit, on its retainer being such as fixed on rolling bearing and the running face that is conducted through is to know wearing and tearing and the fatigue phenomenon in running face.
Therefore, task of the present invention is, provides a kind of device detecting the assembly of rolling bearing, by the device reduces the testing cost of assembly.In addition, task of the present invention is also to propose a kind of method detecting the assembly of rolling bearing.
First task according to the present invention is achieved by the device with feature described in Patent right requirement 1.According to described feature, this device is used to the assembly that Non-Destructive Testing has the rolling bearing of multiple rolling body, when rolling bearing in the mounted state time can enter assembly from the side in the region between two adjacent rolling elements, this device have can introduce rolling bearing, can near the pick-up unit of described assembly, this pick-up unit has at least one sensor for detection components.
In other words: be used to Non-Destructive Testing have the assembly of the rolling bearing of multiple rolling body device (this device when rolling bearing in the mounted state time such as can enter described assembly by the seam of side in the region between two adjacent rolling elements) have by described seam introduce rolling bearing, can near the pick-up unit of described assembly, this pick-up unit has at least one sensor for detection components.If rolling body is placed in retainer, then such as the side of retainer, above and/or below there is described seam.
Therefore, utilize that such device is possible is, the assembly of rolling bearing such as comprises the running face of rolling bearing, rolling body or medial surface, even in the mounted state, namely under assembling and installment state, described assembly is detected, this is because pick-up unit is designed such that can be introduced in the free space between two adjacent rolling elements by side inlet.If rolling bearing has retainer, and rolling body is placed in one, then this type of side inlet be such as retainer side, above or the seam of below, this seam such as only a few mm wide.At this moment, retainer can be configured to integral cage or also can be configured to half retainer, is namely only configured to the spaced ring with rolling body.Therefore, the size that pick-up unit has is less than side inlet or lateral opening, seam between bear box such as above or below retainer around retainer and rolling bearing or the seam between retainer and the bearing shell of rolling bearing, to guarantee smooth introducing.
In this case, Non-Destructive Testing assembly, particularly operate face, both can before rolling bearing being installed into machine or equipment (such as wind power plant), again can when sliding bearing installs, namely in the mounted state, carry out as initial testing or with specific circulation interval time first, and without the need to dismantling rolling bearing.So, can obviously shorten on the one hand because detecting the shut-down and repair time that cause, because without the need to carrying out all the time more time-consuming dismounting, and on the other hand cycle detection also can guarantee better quality and thus reduce the probability that mounted rolling bearing breaks down, this is because assembly can be found early, the fault in the face that particularly operates, defect or change.So just can draw conclusion about rolling bearing serviceable life and take appropriate measures, to avoid such as sequential loss.
In addition, also can by pick-up unit near assembly.In other words: if pick-up unit is positioned at the corresponding terminal location detecting position in rolling bearing, then its approximate flat against or flatly against assembly to be detected, such as operate face, thus make at least one sensor or its surface of emission parallel with receiving plane and with the constant distance of assembly.
In the preferred form of implementation of one, pick-up unit have multiple, arrange successively in a longitudinal direction, for the sensor of detection components.Therefore, pick-up unit has multiple sensor, and it is embarked on journey adjacent to each other or in turn arranges transverse to the rotation direction of rolling body.For this reason, the longitudinal direction of pick-up unit can be understood as following direction, the direction namely extended perpendicular to the rotation direction of rolling body when pick-up unit is positioned at and detects position or terminal location.Especially, by this type of pick-up unit can detect the running face of rolling body or rolling surface or detection side to boundary surface.Larger scope can be detected thus, particularly can detect whole running face in radial directions.Can by the mistake in the hardness in particularly radial running face or difference identification out and position by the measuring-signal recorded by multiple sensor.
In a kind of preferred implementing form of device, this device has extremity piece (Endglied) for pick-up unit being fixed on the roller bearing component of following rolling bearing and rotating.But it is also contemplated that between detection period, manually carry pick-up unit when rolling bearing rotates.If rolling bearing has retainer, then pick-up unit can be fixed on retainer by extremity piece.This can be such as the adapter be shaped according to retainer shape, and this adapter is connected to the rear end of pick-up unit and is fixed on retainer by pick-up unit by it.So, when pick-up unit be positioned at terminal location or detect position time, be namely introduced into rolling bearing and near assembly time, pick-up unit such as can be fixed on retainer via extremity piece.The advantage done like this is, pick-up unit can move with retainer when rolling bearing moves or rotate and thus be guided through such as whole running face.In addition, pick-up unit is also maintained at its terminal location or detects position, and prevents its landing or be stuck in rolling bearing when detecting thus.Not only can use layout position transducer independent on detection means but the position transducer that has been integrated in the driver element of rolling bearing can be used in case measure pick-up unit position or in rolling bearing the path of process.
In the first preferred implementing form, pick-up unit has and is multiplely interconnected via web member and can distinguishes the Connection Element of installation capable of pivoting relative to each other in reference position.In other words: pick-up unit is made up of multiple Connection Element, and it is interconnected, make it can respectively around the pivot perpendicular to pick-up unit longitudinal direction.Wherein, Connection Element such as can rotate from linear direction in one direction, pick-up unit can be introduced rolling bearing around this direction, condition is side inlet (such as stitch) or between the direction of insertion extended along this seam and running face shape is at angle.For this reason, this type of pick-up unit or this type of detector (Pr ü flineal), be particularly suitable for running face of detecting, described running face is positioned at the same plane at described seam place, introduces detector by this seam.In other words: running face can be entered incessantly or continuously via seam.Be exactly such as this situation concerning the outer running face of taper roll bearing.In this case, the length of each Connection Element and quantity can with the running geometric configuration in face and the geometric configuration of side inlet or seam or the geometric configuration of seamed edge to be crossed matches.
Here, web member has the plug-in device connected for setting up connector especially, makes Connection Element in the terminal location adjusting to a line each other of the plug-in device of connector each other.That is, Connection Element is also arranged each other linearly at terminal location direct neighbor, and Connection Element can not move pivotally.Terminal location is here understood as that with upper/lower positions, namely supports the position of the pick-up unit being used for detection components (such as operate face), namely detects position.For this reason, plug-in device is such as configured to, make when applying the power contrary with the direction of insertion of pick-up unit (it is such as produce with stitching on relative retainer carrying plane because pick-up unit free end is supported on), Connection Element can be made to press together or slide into, thus enhance pick-up unit and be placed in terminal location thus.As previously mentioned, easier in insertion being made to stitch by Connection Element.If after the insertion, namely at terminal location or detect position, Connection Element adjusting to a line by plug-in device connector each other, is then guaranteed, pick-up unit and thus sensor put down against or flatly against assembly to be detected.If pulled out from rolling bearing by pick-up unit, then connector connection can be unclamped, and each Connection Element of result is installed again pivotally, and can pass over by running face and stitch the angle surrounded.That is, web member or plug-in device are removably configured on take-up device.
There is the simple possibility of a kind of structure in the connection of this type of connector, condition is that the connection of this connector is connected with joint tongue for tongue-and-groove.In this case, the end face being arranged to the Connection Element between two other Connection Element is furnished with at least one tongue-and-groove, and is furnished with at least one joint tongue on the end face that Connection Element identical with this is relative.At terminal location, tongue-and-groove and the joint tongue of each adjacent Connection Element such as engage each other completely, thus make Connection Element adjusting to a line and direct neighbor.Terminal connection elements is only having a tongue-and-groove or joint tongue towards the end of adjacent connection elements.Except plug-in device, web member also can have other web members, such as, have the elongated hole of pin, and it allows each adjacent Connection Element move pivotally and make it link together simultaneously.
In the form of implementation that another kind is favourable, the Connection Element being arranged in the free end of pick-up unit has block part, and it such as, for being supported on pick-up unit with side inlet or stitching relative carrying plane, on the carrying plane of retainer.In other words: the Connection Element being arranged in front end in an insertion direction has with lower device, pick-up unit can be supported on rolling bearing inside by this device, such as, be supported on inner retainer.If pick-up unit is inserted, until the Connection Element being arranged in free end contacts with carrying plane, and support thereon, then Connection Element can be made to press together, until strengthen pick-up unit and make it near assembly.Wherein, be connected by realizing connector with the counteractive power of direction of insertion, described counteractive power is delivered to Connection Element via block part.It makes Connection Element adjusting to a line and connects, and thus make pick-up unit near or press assembly.
Advantageously, block part is spring element, and it is made up of two legs (Schenkel), and one of them leg is fixed on the flat side of Connection Element and another leg is outstanding from the flat side of Connection Element.Wherein, spring element is such as fixed on the flat side of Connection Element, thus makes the plane being expanded out by described leg and described flat lateral vertical.That is, by one of them leg, spring element is fixed on the flat side of the Connection Element relative with sensor, another leg from flat side outstanding and support on the bearing surface.The advantage of spring element is, because the elastic characteristic of himself does not have obstacle when inserting pick-up unit, prerequisite such as uses narrow seam as side inlet only.
In a kind of substituting form of implementation, pick-up unit has at least one detector (Pr ü flineal), and it is adjustably arranged on guide rail.In other words: be arranged on guide rail at reference position detector on the longitudinal direction of guide rail, in centre position or terminal location, detector and guide rail are arranged with interval.In this case, detector is such as connected with guide rail, and making can perpendicular to the flat side of guide rail scanner to regulate detector.Especially, can detect not in the conplane running face of following seam by this type of pick-up unit, can pick-up unit be introduced by described seam.This is exactly such as this situation concerning running face in taper roll bearing.In order to make pick-up unit must overcome step or stage near running face, that is only just running face can be entered by a step or stage via seam.
In principle it is possible that regulate detector by the motion perpendicular to guide rail.But advantageously, collapsibly detector is connected with guide rail by least one web.Wherein particularly advantageously, detector is coupled with guide rail by least one web, thus to make on the longitudinal direction of guide rail and always to regulate this detector in parallel therewith.In other words: detector is connected with guide rail by least one web, described web can be vertical around the direction of insertion or longitudinal direction with detector pivot deflect, wherein web described at least one in a folded configuration, namely in reference position, it is desirable to be arranged in guide rail completely.That is, detector is coupled with guide rail movement by web, it can be launched from guide rail and again turn up.Wherein, the pivoting action of web particularly carries out as follows, namely to make on the longitudinal direction of guide rail and always moves in parallel therewith or regulate detector.Therefore, to be coupled detector, guide rail and web according to the mode of leverage.
When detector being introduced rolling bearing by side inlet or seam, namely in reference position, web is turned up, thus make detector approximate be arranged on guide rail completely or detector not outstanding from guide rail.In centre position and terminal or detect position, launch web at least in part, thus make detector outstanding or have certain distance with guide rail from guide rail.So, even if running face and seam be not at same plane or can not enter running face point-blank via stitch, also can by detector near the face of running.
In a kind of favourable form of implementation, between detector and guide rail, arrange spring element, for detector is adjusted at least one centre position from reference position.So, prestress is applied with to detector turning up under state.This is such as such as, by being arranged in volute spring between detector and guide rail or also by existing spring element between web and detector, latch plate realizes, and an one leg is fixed on web and its second leg is fixed on detector.When pick-up unit is introduced rolling bearing, when detector has arrived step in rolling bearing or stage completely, spring element can make detector move to centre position automatically.Therefore, detector leaves from guideway path and presses to running face by spring element.If detector touches the inside step relative with outside step, then can continue adjusted, make it move to terminal location completely and near running face.If correspondingly design spring element, or spring element is mated with rolling bearing and running face to be detected, then also can directly make detector move to terminal or detect position by spring element.When pick-up unit is pulled out from rolling bearing, by in the internal direction of rolling bearing, the direction of interior retainer such as, apply power, because detector touches, outside step causes this power, detector can be folded and be arranged on guide rail again, thus make it to be removed from rolling bearing.
In the preferred form of implementation of another kind, web member has spring element, makes Connection Element in relaxed state adjusting to a line each other.Wherein, each adjacent Connection Element such as by being parallel to the flat side arrangement of Connection Element, and connects the spring element be fixed on described flat side.Spring element also allows single Connection Element that (even if being restricted) pivotable each other occurs, thus makes, by side inlet or seam, pick-up unit is introduced rolling bearing.
In addition advantageously, the Connection Element being at least arranged in the free end of pick-up unit has for making pick-up unit near assembly, the magnet in the face that particularly operates.
In order to make the introducing of pick-up unit become easy further, described device has middleware, and it to be arranged between pick-up unit and extremity piece and to be connected with extremity piece with pick-up unit respectively by least one spring element.Middleware to be assigned to orientation approximately perpendicular to the front side portion of pick-up unit and extremity piece in a relaxed state.
In order to Non-Destructive Testing running face, provide in principle the sensor of number of different types for.But advantageously, at least one sensor described is eddy current sensor or sonac or ultrasonic transducer.In addition it is also possible that dissimilar sensor combinations is got up, such as, two sonacs and two eddy current sensors are integrated in same pick-up unit.
The assembly that will detect by device or intraware are in particular the rolling surface of the side of inner ring and/or the side of outer shroud and/or rolling body and/or interior running face and/or outer running face.
Second task solves according to the feature of Patent right requirement 18, this is the method for the rolling bearing assembly by having multiple rolling body for Non-Destructive Testing, wherein can enter described assembly from the side in the region between two adjacent rolling elements when rolling bearing is under installment state, and by device according to any one of claim 1 to 17, wherein introduce rolling bearing from the side and by it near assembly by having at least one pick-up unit being used for the sensor of detection components.
Detecting the assembly of rolling bearing, such as operate face time advantageously, use the first and second pick-up units, wherein the first pick-up unit is operated in the assembly that detects rolling bearing in rolling bearing and second detection device is operated in rolling bearing external detection reference component, namely such as with reference to running face.Then the measured value of these two pick-up units can be compared.Described " reference or control probe " is used likely to draw such as about the conclusion of the first pick-up unit coupling mass in rolling bearing.
The present invention can be set forth further with reference to embodiment shown in the drawings.It illustrates respectively in the diagram:
