Background technology
In rolling bearing and large-size rolling bearing, problem intrinsic is in principle, after longer working time, occur the danger exhausted or material is excessively tired, its form is damage or the damage of raceway or rolling body.Usually, each rolling bearing or each large-size rolling bearing and rotary connecting device and/or moment bearing are considered with the specific life-span and design.
But, nowadays clearly may determine tired definite time point hardly from the beginning, this is because computing time, point was different often from point actual fault-time in practice.Actual some fault-time depends primarily on material condition, working condition and service condition.
Usually always by continuing with oil, grease or other lubricants to lubricate this bearing well or this rotary connecting device is attempted friction to be kept little as far as possible.The serviceable life of bearing, rotary connecting device etc. can be improved in principle by the suitable and lubrication of continuous action.
Aforementioned damage or damage such as starts, this is because raceway is often implemented with the hardness less than the rolling body concured with it along with forming Materials Fracture and/or depression in raceway.These depressions may become large along with the increase of working time, and cause occurring fracture in raceway.When continuing to use rolling bearing, these fractures also cause larger material breaks sometimes, and it may cause the unexpected jam of bearing subsequently, and this may cause which using the whole machine of bearing or rotary connecting device or the fault of unit or vehicle.In addition, break due to aforementioned, also may damage and perhaps be present in distance piece in bearing arrangement or retainer section.
Therefore, there is different technical effort, in order to by suitable diagnosis and/or wear detection equipment in advance (that is, before aforementioned fault appears in whole machine or unit or vehicle) identify the wearing and tearing of such as rolling bearing or large-size rolling bearing.
By prior art so far, the prior art such as illustrated in EP 0,922 870, known following this large-size rolling bearing, it has the wear measurement equipment for large-size rolling bearing constructed in the following manner, namely, large-size rolling bearing is made up of two race rings, and between these race rings, be furnished with the rolling body forming rolling body structure space.Wear measurement equipment is equipped with display, predetermined deflection between its display race ring, and be equipped with probe, it to be arranged in the opening of race ring and can to come in contact with the face of the end of this probe and another race ring, and wherein, the race ring opposite with probe is configured with groove, the end of probe extend in this groove, and wherein, the face of groove has spacing respectively relative to probe, and it is corresponding to the predetermined wear extent along affiliated direction.
According to traditional prior art, also often use this with electricity supply or with the probe of wire bonds or sensor, they are usual works contactlessly, that is, such as transmitted wave, such as, mechanical wave as sound wave or may also be electromagnetic wave.
Fig. 1 shows this large-size rolling bearing according to traditional prior art.
In practice, as long as use contactless (such as transmitted wave) sensor, the following aspect of this technical embodiment in the prior art has just been proved following shortcoming:
Only can monitor or measure the wearing and tearing of ball-bearing groove by the sensor of wear measurement equipment or probe.The effect of wear measurement equipment can not exceed this raceway.So can not measure or sense the damage occurred in the outside of this raceway.
If the sensor of wear measurement equipment or probe are not evenly load with the diameter of inner ring, so this sensor or probe due to be in raceway system break or the swarf and sustaining damage of metal material even damages.
Because often very closely install with screw terminal or nut according to the sensor of the wear measurement equipment of traditional prior art or probe, the surperficial pressing force applying too high or surface force may damage even damage sensor or probe.
Sometimes also need very large structure space according to the sensor of the wear measurement equipment of aforesaid prior art or probe, in practice, particularly can not always provide this structure space when small-scale precision applications.
But cause maximum shortcoming by the shape of groove and position, its as described below:
In principle, first in fact this groove not only collects lubricant most probably, particularly lubricant grease, but also collects the metallic particles in aforesaid break portion or fracture portion.The ripple of these particles possibility appreciable impacts or disturb sensor signal or transmitting.The quality of the signal of sensing or measurement or detection is sometimes obviously influenced due to this impact or interference.Often sensor mass is deteriorated to such an extent as to must queries whole sensing result.
Secondly, the position of this groove and sensor or probe must orientation as follows exactly, that is, bearing gauge wear or tilt and can be detected by sensor or probe or wear measurement equipment.This usually only in sensor tip or probe tip accurately " alignings " groove time just can realize, so this is in bearing only radially loading and just can realizing when not standing inclination in axial direction.But in practice, when particularly stating moment bearing before use, bearing almost always in axial direction occurs tilting.As a result, this groove in axial direction moves or has at least in axial direction reversed certain angular deviation due to moment.When axis inclination or the deflection of bearing, or usually when bearing axial dipole field, the border area of sensor tip or probe tip meeting " aligning " groove or seamed edge region.Because the border area of groove is always gone out by stepped-style boundary, thus, change the value phase step type sensed by sensor tip or probe tip.
Therefore the probe electronics device/electric device connected or sensor electronics/electric device identify the change of the phase step type of attrition value mistakenly.If want to eliminate this wrong identification completely, so similar to the instruction of EP 0,922 870 or identical wear measurement equipment only should be used for only radially loading and the large-size rolling bearing in axial direction do not loaded.
When only there is strong axial dipole field in a race ring, once make the side of groove and sensor tip or tip of popping one's head in collide due to axial dipole field, the application of similar to the instruction of EP 0,922 870 or identical wear measurement equipment just may damage or damage sensor tip or tip of popping one's head in constantly.
But only in the rare cases, the machine of high capacity or unit and vehicle, engineering machinery, crane, mobile type hoist, wind power generating set, tidal power plant etc. are just only loaded as land used by radial load.
Generally speaking, by aforesaid this groove shapes, particularly by the geometric configuration of its stepped-style, such as, in the groove shapes that the technology training centre of EP 0,922 870 describes, reliably can sense at the most such as due to the radial deflection caused that weares and teares, and reliably can not sense axial dipole field.
Summary of the invention
Caused by described prior art and draw problem of the present invention, namely, improving as follows is in operation is applied in the bearing of (strong) power and/or moment or (large-scale) rolling bearing or rotary connecting device in axis and radial direction, that is, operationally accurate and accurately and reliably sensing measure or detection axis to and/or radial deflection and/or moment bearing or (large-scale) rolling bearing or rotary connecting device vertically and/or the state of wear of radial direction.
The solution of this problem by by vertically and/or the radial direction pitch sensors of carrying out measuring or detect be installed to one or more race ring assigned position on and realize, wherein, this pitch sensors respectively can spacing between sensing body (race ring) and measurement mechanism (pitch sensors) or relative motion.This relative motion can or be caused by the wearing and tearing of parts of bearings, or (if desired in a superimposed manner) is by the effect of load to bearing or rotary connecting device, and the power namely introduced due to outside and/or moment cause.
The solution of this problem especially also realizes in the following manner, namely, use at least one contactless sensing in the sense of the present invention, preferably undertaken measuring or detecting by induction type method, alternatively undertaken measuring or detecting by ultrasonic type method or eddy current type method, the pitch sensors measured or detect is carried out if desired by condenser type method, for at least temporarily, but preferably measure or detect at least two race rings axial spacing relative to each other (Δ s) or axial dipole field and/or radial deflection (Δ v) or radial spacing constantly.

Embodiment
By the following explanation of the preferred embodiment of the present invention and obtain based on feature, details, advantage and effect described in each of the present invention in conjunction with following accompanying drawing.
Fig. 2 illustrates non-stepped profile or geometric configuration 11, the v shape in particularly opposite with pitch sensors 4 race ring 6 or the profile of ramped shaped.In this first favourable embodiment of the present invention, the pitch sensors 4 in race ring carries out the end that senses or detect and the profile in axial direction continuing to change in opposite race ring or geometric configuration 11 " opposite.
Fig. 2 is also exemplary describes following design:
This non-staged geometric configuration is ramped shaped 11 with being different from prior art (see Fig. 1) in fig. 2 " implement.This has special advantage, that is, when a race ring in axial direction offsets relative to another race ring, the end A in the side, bearing clearance of sensor 4 and the direct separation delta s of opposite race ring 6 are set as the amount continuing to change, or rather, until the S that culminates.
Such as from the upper axial end in gap 10, profile 11; 11 " this lasting change shows as breach or otch (or being just aforesaid " slope ").
Measuring method due to the spacing tactility apparatus 4 of each contactless work can detect the lasting change of this aforesaid spacing between end A and non-stepped profile or geometric configuration 11 that maybe can sense and maybe can detect in the side, bearing clearance of sensor 4.If such as use the measuring method based on sound wave of pitch sensors 4, the traveling time that so aforesaid spacing changes by the change of sound wave identifies, because speed of sound is such as than higher in the air in bearing clearance 10 in metal material.Even if be filled with oil and/or lubricant in bearing clearance 10, the traveling time of the change of relative (such as race ring) metal material of ripple also can be obtained.
Fig. 3 a illustrates said ramp shape 11 " another flexible program of profile or geometric configuration.In fig. 3 a, this non-stepped geometric configuration 11 is incorporated in moment bearing or (large-scale) rolling bearing 1 by independent body (so-called episome 12) or is incorporated in rotary connecting device 1.This episome 12 can be roughly around circle.See following explanation.
According to Fig. 3 a and/or Fig. 3 b when the summit S of maximum protrusion to be placed on this non-staged geometric configuration or profile 11 and to extend in bearing clearance 10, the aforementioned advantages that non-staged geometric configuration 11 is brought also obtains enhancing if desired.
In Fig. 3 a and Fig. 3 b, this summit S is embodied as tip.That is, in the S of summit, obtain the uncontinuity in the parsing of non-stepped profile 11.
On the contrary in figs. 4 a and 4b, this summit S shows as the peak on curved profile 11, wherein, gives the continuity in parsing at this in the S of summit.
Aforesaid flexible program or embodiment (see Fig. 3 a and Fig. 3 b) are compared with Fig. 4 b with Fig. 4 a, bring very large advantage, that is, summit S is regarded as " switching point " when sensing axial offset delta v.Such as, if in rest position, namely, when moment bearing or (large-scale) rolling bearing 1 do not load or rotary connecting device 1 does not load, the end A of the side, bearing clearance of pitch sensors 4 directly calibrates or orientation towards this summit S, run duration so after this moment bearing or (large-scale) rolling bearing 1 or rotary connecting device 1 can realize simply, detection or the shifted by delta s caused by load and/or wearing and tearing in axial direction detecting or sense from this summit S.
That is, summit S serves as a kind of zero position the measured value of the pitch sensors 4 of contactless work or measurement result or a kind of reference position.
This obviously cannot realize according to the conventional art so far in the meaning of Fig. 1, even if this is because when large-size rolling bearing G axial dipole field, sensor 4 also always points to groove 5, and wherein, this groove occupies the recessed degree of depth high equally all the time along its base.According to the proprietary information that cannot provide in the large-size rolling bearing of Fig. 1 about offset path Δ s in axial direction.
But on the contrary, the summit S of non-stepped profile or geometric configuration 11 indicates the position of the maximum protrusion of the race ring 6 in the face of holding this profile 11 of non-stepped profile or geometric configuration 11 (or alternatively in the meaning of the present invention 1, the position of maximum breach as shown in Figure 2), and because herein is provided appreciable routing information Δ s in axial direction, traditional prior art (see Fig. 1) lacks this routing information.
In very favorable design, for example at Fig. 2 and Fig. 3 a and shown such in fig 3b, non-stepped profile or geometric configuration 11 (alternatively its summit S) and pitch sensors 4, the particularly spaced apart width of bearing clearance 10 with the end A of the side, bearing clearance of pitch sensors 4.
Can also realize in the sense of the present invention, trace back to the non-stepped profile 11 not having summit S, such as shown such in figs. 5 a and 5b.So this is especially placed on race ring 6 at the region B that will sense; Recommend, such as, time near rolling body 8 or between two row rolling bodys 8 time near the convex shoulder of 7 or seamed edge.
The direct spacing of non-staged geometric configuration or profile 11 and pitch sensors 4, especially with the direct spacing of the end A of the side, bearing clearance of pitch sensors, can be under any circumstance such as at least 0.20mm, if desired even can between 0.20 and 9.5mm on a large scale in, ideally even between 1.0mm and 4.0mm.
Also found out that, according to the present invention and according to advantageous manner, pitch sensors 4 is always incorporated in the race ring 6 opposite with contactless profile or geometric configuration 11.
Fig. 3 a and Fig. 3 b and Fig. 5 a and Fig. 5 b has region B, there is non-stepped profile or geometric configuration 11 in this region.This region B preferably designs as follows roomily, that is, the end A in the side, bearing clearance of pitch sensors 4 and the spacing that can keep at least 0.2mm or 3.5mm between the non-stepped profile in opposite race ring 6 or geometric configuration 11.
According to advantageous manner, each pitch sensors 4 is incorporated into for holding in the mechanism 9 of sensor respectively along its longitudinal axis or L extending longitudinally, is preferably incorporated into in the gauge hole 9 of cutting way introducing.
In practice, via engage pressing or tighten (alternatively, even via bonding and/or by safety plug) carry out the introducing in this wise of at least one pitch sensors 4.
This mechanism 9 for holding sensor, such as gauge hole or sensor are left a blank portion, can manufacture with cutting metal processing mode or in the mode of non-cutting intermetallic composite coating, such as, by Foundry Production technology or cold mould production technology or punching production technology or shear production technology and manufacture.
Be proved to be as particularly advantageously, each moment bearing or (large-scale) rolling bearing 1 or rotary connecting device 1 exist multiple pitch sensors 4, such as shown in Fig. 6 a and/or Fig. 6 b.
Therefore, three pitch sensors 4 can be introduced in race ring 7, and aim at along the direction (in any case always along the direction of bearing clearance 10) of another race ring 6 with the end A of its side, bearing clearance, wherein, such as three pitch sensors 4 can along clockwise direction spaced apart separately from each other 120 °, or such as four pitch sensors 4 can along clockwise direction spaced apart separately from each other 90 °.According to the relative Fig. 6 b of rear a kind of embodiment of Fig. 6 a, there is following advantages, namely, each arc section has introduced sensor 4, compared with only having three sensors 4 with each moment bearing or (large-scale) rolling bearing 1 or rotary connecting device 1 thus, measuring technique obtains more how appreciable data.
According to the instruction of the present invention 1, bearing clearance 10 (alternatively region B) between pitch sensors 4 (particularly the end A of the side, bearing clearance of pitch sensors 4) and non-stepped profile or geometric configuration 11 is filled with grease or oil or lubricant, especially to promote the even hyperacoustic conduction of sound wave, because of by physically it is known that, sound wave even ultrasound wave in fluid media (medium), even if having in viscous fluid medium than velocity of propagation higher in air dielectric.
With regard to this respect, the bearing clearance 10 of filling with oil or lubricant is in the sense of the present invention better than the bearing clearance 10 of " ventilation ", the bearing clearance 10 of that is " filling with air ".But, it not the method that use is undertaken by sound wave measuring or detecting, but such as use the contactless measurement method for distance of pure induction mode effect, thus bearing clearance 10 is filled with fluid (particularly oil and/or lubricant) still not have extend oil/lubricant (that is, only " filling with air ") to be inessential.
When in the common mechanism 9 that multiple pitch sensors 4 is inserted or is pressed into or be screwed into for holding sensor, the present invention works especially well.At this advantageously, radial deflection Δ v or radial spacing Δ v is measured or sense or detected to such as the first pitch sensors 4, and the second pitch sensors 4 is measured or is sensed or detection axis to separation delta s or axial offset delta s.
Therefore, the application person of the present invention 1 obtains two race rings 6 equally; 7 are not only in axial direction and are effective offset data radially and/or spacing data, especially in wear direction and/or load direction.
In principle, moment bearing or (large-scale) rolling bearing 1 or rotary connecting device 1 according to the present invention can design as follows, that is, what the axis of non-stepped profile or geometric configuration 11 extended not more than about 20.0mm and/or non-stepped profile or geometric configuration 11 radially extends not more than about 10.0mm.In conjunction with actual and therefore particularly advantageously, such as this non-stepped profile or geometric configuration 11 ramped shaped 11 " (such as with the angle between 5 ° and 95 °; the angle preferably between 30 ° and 65 °; the angle of especially about 45 °) implement; preferably; wherein, preferably at formation summit, the end points place S on slope.
Aforementioned episome 12 is made up of metal material ideally, such as, be made up of ferromagnetic material, such as, to rise and pitch sensors 4, the effect of especially opposite with the bearing clearance side end A of pitch sensors 4 measuring basis body.
In further embodiment of the present invention, episome 12 may be embodied as coil or the conductor circuit of ring-type, and it preferably relatively holds this episomal race ring by electrically insulating material (such as pottery or elastomeric material or plastic material or cardboard or paper material) and is separated on electromotive force.
The instruction of the present invention 1 is also arranged, non-stepped profile or geometric configuration 11, even alternatively episome 12, and cyclic rings is installed around ground or is introduced at least one position of this profile of accommodation or geometric configuration/episomal race ring.
At this, even can carry out installing or introducing in the mode of ring section, from but not stepped profile or geometric configuration 11 or alternatively episome 12 install or introduce, preferably can not releasably installing or introduce, alternatively bondingly the race ring 6 that even can be pressed into and it is held maybe can be welded; In at least one ring section of 7.
The summit 12 mentioned before getting back to, which defines the maximum protrusion 11 of non-stepped profile or geometric configuration 11
*.This protrusion can also be implemented (breach) in former mode.But due to severe notch effect, the performance of preferred formpiston mode.Even if in order to there be this protrusion 11
*when still guarantee the assembling capacity of the present invention 1 in practice, this protrusion should be up to about 4/5ths of the width of bearing clearance 10, such as, be up to 7.5mm.
