Definitions
- the invention relates to rolling bearings with sensors that are used in a wide variety of applications to measure the force acting on rolling bearings and the temperature.
- Rolling bearings with sensors have the task of measuring the operating conditions that exist at the rolling bearing in order to then be able to control or regulate the entire process of the machine arrangement with these measurement data.
- Rolling bearings with sensors are used for force measurement, direction of rotation measurement, rotation speed measurement and temperature measurement.
- Such roller bearings with sensors are also known, inter alia, from US Pat. No. 5,952,587.
- the use z. B. strain gauge sensors and the evaluation of these measurement results are described in detail in the document.
- the problem with this document is that for rolling bearings with different numbers of rolling elements, different numbers of cables have to be routed from the rolling bearing to the external evaluation unit. The problem is therefore that the evaluation unit must be designed differently depending on the rolling elements currently used in the rolling bearing. Object of the invention
- the essential essence of the invention is that a standardized interface between the rolling bearing and the evaluation unit is introduced.
- This standardized interface makes it possible to always provide the same information at the interface regardless of the number of rolling elements in the rolling bearing.
- This is achieved in that the rolling bearing z. B. is divided into three (claim 2) 120 degree areas. All sensors that are in a 120 degree range are evaluated by means of an ASIC arranged on the roller bearing, so that a force vector results for this range.
- a region ASIC here carries out a vector addition of the individual vectors, which are determined by the sensors, in order to form an overall vector.
- the force vectors of the three area ASICs are thus permanently present at the interface between the rolling bearing and the evaluation unit.
- Each of the three ASICs thus passes information that contains the amount of force and the direction of the force in the respective area.
- These three area vectors are then added vectorially in the evaluation unit, and a vector which corresponds to the total load on the rolling bearing is thus determined.
- the rolling bearing is divided into 4 areas of 90 degrees.
- the difference compared to claim 2 is that 4 range ASICs are used to determine the force vector (amount and direction). Otherwise, the further procedure corresponds to claim 2.
- the invention is illustrated in a figure.
- the side view shows schematically a rolling bearing consisting of the outer ring 1, the inner ring 2 and the rolling elements 3.
- 9 rolling elements are shown in the example.
- the sensors 4, 5 are arranged schematically on the outer ring 1.
- the sensors are arranged in a groove on the outer ring.
- the sensors 4, 5 are arranged such that the sensor distance corresponds to half the distance between two rolling elements.
- the sensor 5 is currently arranged directly in the rolling contact, while the sensor 4 is arranged exactly between two rolling bodies.
- the sensors 4 and 5 represent a strain gauge half-bridge 6, two further sensors being arranged outside the load zone of the roller bearings, which serve for temperature compensation of these two sensors 4 and 5.
- the area ASIC Also located in the groove of the rolling bearing is the area ASIC, which adds up the results (in the drawing of three rolling elements) for an area of 120 degrees.
- the current angular position in the 120 degree range (of the respective strain gauge half bridge) is given to the range - ASIC via the factors d, c2 and c3 for range 1 and c4, c5 and c6 for range 2 and c7, c ⁇ and c9 for the Range 3 passed on, d to c9 are scalars which correspond to the angular position of the individual sensors in a range.
- the area ASICs now form the area vectors 7, 8, 9 from the measured values. These area vectors (amount and direction) 7, 8, 9 are transmitted to the evaluation unit via a defined interface.
