Definitions
- the invention relates to an arrangement, in particular a bearing arrangement, two rotating components, comprising a first rotating member and a second rotating member, wherein the two components are arranged axially adjacent to each other.
- the invention is based on the object of providing an arrangement, in particular a bearing arrangement, of the generic type such that it is possible to install monitoring in a simple and convenient manner in terms of whether the two axially adjacent rotating components, in particular the bearing rings, remain in their intended relative position.
- the solution to this problem by means of the invention is characterized in that at least one support element is arranged on the first component, to which a bending beam extending in the axial direction is fastened, a deflection element being fastened to the second component, into which element the Supporting element facing away from the bending beam engages so that the end is deflected in a radial displacement of the second component and / or displacement of the second component in the circumferential direction relative to the first component in the radial direction and / or in the circumferential direction, and wherein measuring means are provided to the Deflection of the bending beam from a zero position to measure.
- the arrangement is preferably a bearing, in which case the two components are preferably two inner rings on which the support element or the deflection element are fastened. These inner rings are designed as rotating rings, d. H. the one or more associated outer rings are arranged stationarily in a housing.
- the deflection element may be formed as a ring having an introduced into an end face annular groove which is formed for entry of the end of the bending beam.
- the deflection element can also be designed as a block element which is fastened to the bearing ring at the same circumferential position as the support element (important in the case of the detection of displacements in the circumferential direction).
- the measuring means are preferably designed as strain gauges, which are attached to the bending beam.
- the measuring means may advantageously be in communication with a data transmission element, wherein the data transmission element is designed to transmit data wirelessly to a receiver. In this way can be dispensed slip rings for data transmission.
- an acceleration sensor On the support element or on the deflection element can be arranged in a further development of the invention, an acceleration sensor.
- This acceleration sensor is preferably designed to detect accelerations in two mutually perpendicular directions, wherein the directions lie in a vertically arranged plane. As will be seen, in this way the rotational position of the measuring point, i. H. of the support element to be determined.
- the acceleration sensor is preferably also connected to the data transmission element in order to be able to transmit measured acceleration data to the receiver.
- the data transmission element may further be associated with a power source.
- the energy source may be a battery or include a generator that gains electrical energy from the rotation of the bearing assembly.
- the proposed embodiment of a (bearing) arrangement allows the measurement of the relative movement in the radial direction and also in the circumferential direction, which results between two adjacent components (bearing rings). there it is preferably two adjacent bearing rings that rotate during operation.
- a further embodiment of the invention provides a further sensor element (for example designed as an inductive or optical measuring element) with which the axial distance between the two components (bearing rings) can be measured.
- a further sensor element for example designed as an inductive or optical measuring element
- All measurement data can be wirelessly transmitted to a receiver, providing the ability to measure relative radial displacements between the two components, relative displacements in the circumferential direction and / or relative axial displacements, and transmit them wirelessly to a receiver. Accordingly, it can take place in particular with large bearing arrangements a related monitoring, so that at any time the proper operating condition of the device can be verified.
- the acceleration sensor determines by means of the acceleration sensor, the angular position of the two bearing rings in a fixed reference frame, d. H.
- the rotational position of the measuring point is easily identifiable. Dispensable for the angular position determination are in particular cost-intensive optical sensors or other angle encoders, with which so far the rotational position of a rotating part can be determined.
- the wireless transmission of data to an external receiving device ensures a simple structure, since it is possible to dispense with known slip rings and similar components.
- a particularly preferred embodiment of the invention combines the measurement of the radial, circumferential or axial Shifting of the two components, detecting the rotational position of the components by means of the acceleration sensor and the wireless transmission of these measurement data to a receiver.
- a bearing 1 can be seen, which is designed here as a double-row tapered roller bearing. It has an outer ring 17 with two raceways for rolling elements 18. The rolling elements 18 run radially inward on corresponding raceways of the two bearing inner rings 2 and 3.
- the outer ring 17 is arranged stationary in the present case. It is a bore 19 indicated in the outer ring 17, via which the outer ring 17 can be screwed to a housing, not shown.
- the two inner rings 2, 3, are arranged in the axial direction a next to each other and directly adjacent to each other. They also have holes 20 through which they can be screwed together. However, this does not always ensure that, during operation of the bearing arrangement, relative radial movements take place between the bearing inner rings 2, 3 (that is to say relative movements in the radial direction R) when the inner rings 2, 3 rotate.
- the bearing arrangement provides a support element 4 which is fastened to the bearing inner ring 2 at a circumferential location (several of these support elements 4 can also be distributed around the circumference).
- a thin bending beam 5 is fixed, which in axia- le direction a extends.
- a deflection element 6 is attached. This can circulate annularly around the entire circumference of the inner ring 3 or even - formed as a block-shaped body - be attached to a peripheral point of the bearing ring 3.
- the deflecting element 6 has in the exemplary embodiment on an end face 9 an annular groove 10 which is formed to the entry of the end 7 of the bending beam 5, which is directed away from the support element 4.
- a spherical enlargement of the existing metal bending beam 5 at one end 7 is selected so that the clear distance of the annular groove 10 in the radial direction R is just filled by the spherical enlargement.
- strain gauges 8 are in communication with a data transmission element 11, i. H. the data transmission element 11 registers the signals coming from the strain gauges 8.
- the data transmission element 11 is in communication with and powered by a power source 14 (battery).
- the data transmission element 11 is designed for the wireless transmission of data, for which purpose it has an antenna 15. This sends signals to a receiver 12, which likewise has an antenna 16.
- an acceleration sensor 13 is further arranged on the support member 4.
- the acceleration sensor 13 is designed to detect accelerations at least in two mutually perpendicular directions, the directions lying in a vertically arranged plane.
- This vertically arranged plane comprises in the exemplary embodiment the radial direction R.
- the acceleration sensor 13 can thus detect the direction of gravitational acceleration. This vertical downward acceleration makes it possible in a simple manner to determine the rotational position or rotational position in which the acceleration sensor is located. Ie. It can be determined by means of the acceleration sensor 13, the rotational angle position at which the support element 4 is located.
- a separate (not shown) sensor can be provided. Another way of determining the same is that the acceleration signal that the acceleration sensor receives is evaluated over time. The gravitational acceleration always directed downward represents a modulation of the continuously radially directed measured centripetal acceleration, so that the rotational speed of the bearing rings 2, 3 can be determined by the evaluation of the signal.
