Description

DEVICE FOR MEASURING THE FORCES GENERATED BY A ROTOR IMBALANCE}

Such a device for measuring the load caused by the imbalance of the rotor, comprising a hollow measuring shaft rotating in two bearing units which are arranged axially apart and supported by a load sensor. It is known to install opposite the bearing housing. The mounting of this measuring shaft is supported by the fixing frame.

From EP 0 343 265 A1, in the case of a balance tester, a backing girder extending in the direction of the center axis of the measuring axis and pivoting with respect to the fixed frame, and arranged at a distance from each other in the axial direction It is known to arrange the sensors between this support girder and the fixed frame. From DE 33 30 880 A1 it is known to support a support which receives a rotational installation of the measuring shaft on a fixed frame via a force transmitter arranged at a distance in the direction of the central axis. .

In the apparatus used for testing the balance of automobile wheels known from EP 0 133 229 A1, the measuring axis is contained in a mounting with a load transmission and supported on a fixed frame. In addition, for the dynamic balance test, two mounting surfaces on which the load transmission part is arranged are provided in the mounting part of the measuring shaft.

EP 0 058 860 B1 is an elastically flexible flat part in which a measuring axis is arranged vertically on a balance tester bed as a balance tester for a rotary body. It is known to be rotatable on. For this purpose, the rotary mounting portion of the measuring shaft is provided at the upper edge of the flat part. The position movement of this flat part is sensed through the arm of the sensor extending at right angles to the flat part, and the load transfer parts of the sensor extend perpendicular to each other. In this regard, one of the sensors records the static content, while the other sensor causes the load resulting from the dynamic imbalance and twisting of the elastically flexible vertical plane near the centerline, for example. Detect the load

Furthermore, from DE-AS 16 98 164, the rotor mountings are on leaf springs located diagonally to each other, the extension of which extends with one of the balancing planes of the rotor being balanced. Vibration (supercritical) measurement systems are known that form virtual intersections. The two leaf springs located diagonally to each other are supported relative to the base plate via an intermediate plate on upright leaf springs arranged parallel to each other. The vibration of the leaf spring due to the rotor imbalance is sensed by the vibration converter and converted into a measurement signal accordingly.

From DE-AS 10 27 427 and DE-AS 10 44 531 it is known to form joints by thinning points in the case of spring bars or leaf springs which form a vibrating installation in a balance tester. It is.

In known devices the load sensor provided at the measuring point in the mounting surface supplies a sensor signal which is proportional to the centrifugal force due to the rotor imbalance and which represents the reaction force measured by the sensor. In a typical standard measuring system used for wheel balance testers, floating mounting on the measuring axis and the rotor fixed thereto is typical. For dynamic balancing against imbalances, there is a translation onto two balancing planes on the rotor based on the force lever law of statics. In this way, the load measured by the sensors at the two mounting surfaces is independent of the respective distances from the two sensors to the rotor. Because this distance is different, the balance test calculated for each balancing surface when the sensitivity of one of the two measuring transducers changes due to other effects such as temperature, aging, impact, transient loads, shaking during transport, humidity, etc. There is a superproportional error in the balancing masses.

The invention relates to a device according to the introductory clause of claim 1 as known from DE 33 32 978 A1.

Technical problem of the present invention

The technical problem of the present invention is to make a device of the type described above, in which the change of sensitivity of the measuring transducer due to the dynamic fluctuation of the load described above is performed in terms of balancing, for example, by attaching a balancing weight. To provide a device that only slightly affects mass balancing.

This technical problem is solved by the present invention having the characteristics of the claims.

For this purpose, in the installation surface on which one load sensor is arranged, an intermediate frame having a large rigidity on which the measuring axis is supported is supported on the fixed frame via an additional load sensor. As such, two load sensors are placed in two installation systems for measuring an unbalanced load, each load sensor being assigned to one of the two installation systems. The two mounting systems lie between a rigid frame and a measuring axis, such as a balance tester in which an imbalance measurement is made on an automobile wheel. In this respect, the load sensor may be disposed on other mounting surfaces or a common mounting surface lying in the region of the intermediate frame having high rigidity.

In addition to the configuration of the two installation systems described above, at least one further support of the measuring shaft having the characteristics of a virtual installation point in an additional installation surface is provided. Two such installation surfaces may be provided with such a virtual installation point. The virtual installation point may be located on both sides of the rotor to be measured. However, it is also possible to provide only one additional installation surface with virtual installation points. This mounting surface is also preferably located between the two balancing surfaces of the rotor or between the rotor and the surface on which the load sensors are located.

The two load sensors are preferably arranged on a common mounting surface extending perpendicular to the central axis of the measuring axis. The loads introduced into the load sensor as reaction forces are parallel to each other, in particular coaxially located on a common mounting surface. The load sensors may lie in the region of the central axial extension of the intermediate space at the other mounting surfaces.

The preferred configuration is that the measuring axis is supported on the intermediate frame at the first mounting surface on which the load sensor is arranged and on the second mounting surface on which the virtual support point is located, and on one mounting surface the intermediate frame is connected via the second load sensor It is supported by the fixed frame and is further connected to the fixed frame by a parallel guide. The mounting surface on which the virtual support points are arranged is in particular located between the rotor, such as a car wheel, and the mounting surface with two load sensors, preferably between the two balancing surfaces of the rotor, in particular a car wheel.

The intermediate frame can be supported through a pair of support levers and joints at each end of the levers. In addition, the measuring axis can be supported at the pair of support levers and the lever ends on the intermediate frame. The central axis of each joint extends perpendicular to the plane on which the central axis of the load and measuring axis is introduced into the load sensor. The pair of support levers that support the intermediate zone to the stationary frame can simultaneously provide parallel guides of the intermediate zone. For this purpose, the support levers extend parallel to each other. However, it is also possible for the support levers to be arranged at a certain angle to each other, ie the apex of that angle, preferably lying on or near the central axis of the measuring axis. In doing so, the joints of the support lever are supported at a trapezoidal corner which is the contour of the support lever. This arrangement creates a virtual installation point lying outside the rotor. The hypothetical installation point may be formed by a support lever inside the rotor, in particular between the balancing surfaces and arranged at an angle with respect to each other, wherein the joint of the lever is an equilateral trapezoid which is its support lever structure. Is supported at the corner of the The support lever may be provided with a sheet metal part, cast part, rolled flat part and the like so that, for example, a substantially linear and axially directed load is introduced into the sensor along the joint. It is preferable to form the flat part with the same rigidity. The support lever structure formed from the flat portion may consist of one body, wherein the flat portion is only rigidly constructed with rigidity and interposed substantially linearly extending therebetween. The joints may be formed by a weak point, such as a constriction between individual flexible flats. In this way, a flexible joint central axis is formed between the flexible flats. Then, according to the configuration according to being parallel or at an angle as described above, a desired virtual installation point is generated at each installation axis extending linearly.

The hypothetical installation point is considered in the frame calculator of the balance tester and is also a measurement point representing the virtual measurement point.

A schematic diagram of a rotor 1 is attached to the measuring shaft 2 in a known manner by means of fastening means (not shown in more detail) for measuring the imbalance. It is. The measuring shaft 2 is provided to rotate on the fixed frame 6. This frame may be a machine frame of a wheel balancing machine. The installation is by means of an installation part 3 which also has a load sensor 4, 5, which will be described in detail below. The mounting portion 3 may have an annular rotary bearing 26 on which the measuring shaft 2 is installed to rotate. The rotary bearing 26 receiving this measuring shaft 2 is fixedly mounted on the sensor 4 on the intermediate frame 7 on the first mounting surface 8b. Furthermore, virtual support points 24 are created on another mounting surface 9 by support levers 13 and 14 which form one support lever pair and extend at an angle to each other. This support point 24 functions like a swivel pin extending perpendicular to the direction in which the reaction force resulting from the unbalance measurement is introduced into the sensor 4. The support levers 13 and 14 are connected to the intermediate frame 7 flexibly (at joints 19 and 22) at their ends and flexibly (at joints 20 and 21) to the measuring shaft 2. Is connected to the rotary bearing 26 of The joint central axis of the joints 19 to 22 extends parallel to the kingpin formed at the virtual installation point 24. The virtual installation point 24 may be placed between the installation surface 8 where the rotor 1 and the load sensors 4 and 5 are located (see FIGS. 1 and 2). However, the hypothetical installation point 24 may also be placed in the region of the rotor, in particular between the balancing surfaces 27 and 28, which are unbalance tested, for example by attaching a balancing weight (FIGS. 5 and FIG. 5). 6).

The intermediate frame 7 is fixed on the stationary frame 6 via the load sensor 5. This load sensor 5 is arranged on the mounting surface 8 which is placed perpendicular to the measuring axis 2. However, you may arrange | position the said load sensor 5 on the other mounting surface which moved to the center axis direction of the said measurement axis | shaft 2. Moreover, the intermediate frame 7 is supported via a pair of support levers 11, 12 on the stationary frame 6. The support levers 11 and 12 are flexibly connected to the fixed frame 6 (joints 15 and 16) at their ends, and flexibly connected to the intermediate frame 7 (Figs. 2, 4 and In addition to the joints 19 and 22 of FIG. 6, the joints 17 and 18 of FIGS. 1, 3, 5, 10 and 7 to 9 are connected. The intermediate frame 7 is composed of a mounting block having a large rigidity or a mounting frame having a large rigidity.

In the configurations of FIGS. 5-9 as well as FIGS. 1 and 2, the support levers 11, 12 are substantially parallel to each other and parallel to the central axis 23 of the measuring axis 2. In this way, the support levers 11 and 12 introduce the reaction force generated during the imbalance measurement process into the load sensor 5 (which is substantially oriented perpendicular to the central axis 23 of the measurement axis 2). To form a parallel steering guide.

3, 4 and 10, the two support levers 11 and 12 are arranged at an acute angle, the apex of which is the central axis 23 of the measuring axis 2. Or its central axis 23. This vertex lies on the outside of the rotor 1 and forms an additional virtual installation point 25 at the installation surface 10 extending perpendicular to the measurement axis 2.

In the configuration of FIG. 10, the imaginary installation point 25 and the installation surface 10 are in dotted lines extending from the installation portion 3, which extend in the opposite direction to the direction in which the measurement axis 2 extends in the longitudinal direction. It lies on the extension of the marked measuring axis 2. The installation point 25 and its associated installation surface 10 lie on the opposite side of the rotor 1 with respect to the installation portion 3.

In addition, the virtual installation point 25 has the characteristic of the kingpin located perpendicular to the center axis 23 of the measuring axis 2, and to the direction in which the load is introduced to the load sensor 4,5. Have In the embodiment, the introduction of such a load takes place at the installation surface 8. The joint axes of the joints 15 to 22 are parallel to each other, perpendicular to the central axis 23 of the measuring axis 2, in order to form the kingpin's characteristics at each virtual installation point 24, 25. It extends perpendicularly to the direction of introduction of the reaction force from the face 8 to the load sensors 4 and 5.

In the embodiment of FIGS. 3 and 4, installation surfaces 9, 10 are created with virtual installation points 24, 25 on both sides of the rotor 1, ie inside and outside the rotor. The virtual installation points 24 and 25 have the property of a virtual measuring point. The load L assigned to the inner installation point 24 and the load R assigned to the external installation point 25 are applied to the load sensor 4. The load sensor generates a sensor signal L '(R') accordingly. The hypothetical measurement points are also generated at the virtual installation points 24 and 25, which means that when the centrifugal force due to the rotor imbalance is combined with the left installation surface 9, the measurement signal L 'is proportional to the value of this centrifugal force. This is due to the fact that is emitted by the load sensor 5 rather than by the load sensor 4. When the outer mounting surface 10 on the right side engages with the centrifugal force R due to the unbalance of the rotor, the measurement signal R 'which the load sensor 4 is proportional to, while the load sensor 5 does not emit any signal. Emits. Due to this, the floating installation in which the balancing surfaces 27 and 28 are placed on the rotor 1 between the virtual measuring points or the measuring surfaces in the mounting surfaces 9 and 10 as in FIGS. 3 and 4. (floating mounting) is caused. If a load is exerted between the mounting surfaces 9 and 10 due to the imbalance of the rotor, the effective mounting loads on these surfaces (virtual measuring surfaces) are divided according to the mounting distance from the working point, so that the sensor signal is loaded into the load sensor 4 It is come out by (5).

In the configuration of FIG. 10, one imaginary installation point 24 in which the centrifugal force L due to the imbalance of the rotor can be effective is between two balancing surfaces 27, 28, preferably approximately two balances. It lies on the installation surface 9 between the adjustment surfaces 27 and 28. Another virtual installation point 25 lies opposite the extension of the measuring axis 2 with respect to the installation part 3. Here, the centrifugal force R due to the imbalance of the rotor is dynamic. As described above, the sensors 4 and 5 emit a measurement signal R '(L') proportional to the centrifugal force R (L).

In the configuration of FIGS. 5-9 as well as in FIGS. 1 and 2, since the support levers 11, 12 create substantially parallel guides of the intermediate frame 7, the virtual installation point on the outside is It lies at an infinity or relatively large distance, for example approximately 3-20 m or more. If the centrifugal force (L in Figs. 1 and 2 and S in Figs. 5 and 6) due to the imbalance of the rotor is a virtual installation point (virtual measurement point) in the configuration of this installation surface 9 (virtual measurement surface) This load is detected only by the load sensor 5, resulting in a proportional signal L '/ S'. On the other hand, the load sensor 4 does not emit a signal. Regardless of the distance of the centrifugal force applied, the load sensor 5 will only emit a signal proportional to the centrifugal force due to the parallel guide of the intermediate frame 7. On the other hand, the load sensor 4 will emit a measurement signal M 'which is not only proportional to the centrifugal force value, ie an imbalance value, but also proportional to the distance of the load operating point of the installation surface 9 or the virtual installation point 24.

1, 3, 5 and 10 as well as in the configuration of FIGS. 7 to 9, the intermediate frame 7 is fixed frame 6 by a pair of support levers formed by support levers 11 and 12. Supported by a pair of support levers formed by the support levers 13 and 14, and the tubular rotation mounting portion 26 of the measurement shaft 2 is supported by the support shaft 13. When viewed from the axial direction, they lie one after another. In the configuration of FIGS. 3 and 4, the support lever pairs have the same inclination direction. In the embodiment, the inclination directions of 11 and 12 are opposite to the inclination directions of the support lever pairs 13 and 14. 2, 4 and 6, with each support lever pair 11, 12 and 13, 14 installed one after the other in the up and down direction, the intermediate frame 7 is supported on the fixed frame 6 and measured The rotary mounting portion 26 of the dragon shaft 2 is supported on the intermediate frame 7. In addition, as in FIGS. 2, 4 and 6, the joints 17, 19 and 18, 22 may be integrally formed in 19 and 22, which are common joints on the intermediate frame 7.

The support levers 11 to 14 may be formed by a flat part that is designed with great rigidity. The flats may be formed in one body, at which joints are formed in the form of a linear weak point, for example a constriction. As can be seen from Figs. 7 to 9, a retaining plat 33, which is a part of the retaining device 29, can also be formed from the portion forming the flats for the support levers 11-14. Can be. The holding plate 33 is fixedly connected to the tubular rotary installation part 26 by welding, for example. Furthermore, an angle bracket 34 may be provided as part of the retaining device 29, which is fixedly connected to the retaining plate 33 and the rotating installation 26 by welding, for example. In the figure, an upper angle bracket 34 is shown. In addition, a lower angle bracket may be provided. The upper and lower angle brackets may consist of one elbow, with the rotary installation 26 guided through one opening of the elbow and fixedly connected in a welding-like manner. In this way, a rigid connection between the retaining device 29 and the rotating installation part 26 is made between the two joints 20, 21. The joints 20, 21 are between the two support levers 13, 14 and the retaining plate 33.

From the portion where the flat portion for the support levers 11 to 14 is formed, an attaching plate 37, 38, 40, 41 may be formed. The attachment plates 37 and 38 are fixedly connected to the fixing frame 6 by, for example, bolting or the like. The attachment plates 37 and 38 form an attachment point for the support lever arm which is formed by the support levers 11 and 12 supporting the intermediate frame 7 on the fixed frame 6. do. Between the flat plates forming the attachment plates 37, 38 and the support levers 11, 12, joints 15, 16 are formed by linear soft points / stenosis. The weak point has a recess, in particular a semicircular cross section.

Furthermore, two attachment plates 40 and 41 fixedly connected, for example, by bolting, welding, or the like, are formed in one body on the side of the intermediate frame 7. Between the two attachment plates 40, 41 and the support levers 11, 12, joints 17, 18 are formed by the weak point / stenosis. Between the flat portions forming the support levers 13 and 14, joints 19 and 22 are formed by the weak point / stenosis.

In this way, the whole mounting part 3 which supported the measuring shaft 2 on the fixed frame 6, and set the virtual installation point and installation point is actually formed in one body.

The parallel guiding of the intermediate frame 7 on the stationary frame is parallel with the concave constriction 15, 17, 16, 18 being roughly guided by the two support levers 11, 12. It is substantially derived from the fact that it lies on both sides of the support levers 11 and 12 on one side 35 and 36. Each of the constrictions 15, 17 and 16, 18 are located on opposite sides of the support levers 11 and 12 forming the flats. However, although the support levers 11 and 12 are inclined at extremely acute angles to each other, as described above, a parallel steering guide is obtained by the guide function on the parallel surfaces 35 and 36. In this manner, the measuring apparatus according to FIGS. 1 and 5 can be obtained. To obtain the measuring device according to FIG. 3, the support levers 11 and 12 can be inclined to one another at a wider angle to one another.

In order to carry out the embodiment shown in FIG. 10, the support levers 11, 12 of FIGS. 7 to 9 are intended to face each other at their rear ends. The rear constriction / joints 15 and 16 are closer to the central axis of the measurement axis 2 than the front constriction / joints 17 and 18.

As in FIG. 8, two load sensors 4, 5 are arranged at the baseline, the load sensor 4 being located between the rotary installation part 26 and the inner part of the intermediate frame 7. The sensor 5 is located between the outer part of the intermediate frame 7 (attachment plate 41) (see FIG. 9) and the fixed frame 6.

In order to drive the measuring shaft 2, an electric motor 30 is provided which drives the measuring shaft via the belt drive 31. The motor 30 is mounted to the rotary installation 26 via an extension arm. By this installation, the measurement result is not affected by the disturbance caused by the motor drive.

Viewed in the central axis direction, a compact mounting portion 3 is created for mounting the measuring shaft 2 on the fixed frame 6. This occurs, in particular in connection with the reduction of the dynamic fluctuations of the load in the floating mounting of the measuring shaft 2, for example, as the temperature, aging, impact, transient loads, vibrations and humidity during transport vary. It reduces the sensitivity change of the load recorder, reduces the need to replace the load sensor to recalibrate the measuring device after transport and setting of the instrument, reduces service costs, improves measurement accuracy and digitizes the analog measurement signal. In addition to reducing the need for analysis of the AD converter, the virtual distance of the measuring surface can be made larger despite the compact configuration. In stationary mounting of the measuring shaft, the dynamic fluctuations of the load are reduced, similar to the measuring device with two mounting points on both sides of the rotor.
