Eine Aufgabe der Erfindung ist es, ein verbessertes Wälzlager zu schaffen, bei dem wenigstens ein Sensor zum Erfassen einer auf das Wälzlager wirkenden mechanischen Kraft geschützt, am eigentlichen Wälzlager einfach und kostengünstig angebracht ist.A The object of the invention is to provide an improved rolling bearing in which at least one sensor for detecting a on the rolling bearing Protected mechanical force, at the actual rolling bearing easy and inexpensive is appropriate.
Die Aufgabe wird durch den Gegenstand des Anspruchs 1 gelöst. Vorteilhafte Ausgestaltungen sind in den Unteransprüchen beschrieben. Der Anspruch 12 beschreibt eine vorteilhafte Verwendung des Wälzlagers des Anspruchs 1.The The object is solved by the subject matter of claim 1. advantageous Embodiments are described in the subclaims. The claim 12 describes an advantageous use of the rolling bearing of claim 1.
Gemäß Anspruch 1 ist bei einem Wälzlager mit einem Außenring, einem Innenring und dazwischen angeordneten Wälzkörpern der Außenring von einer ringartigen Sensoraufnahmevorrichtung umgeben, die wenigstens einen innerhalb einer Axialerstreckung des Außenrings angeordneten Sensor zum Erfassen einer auf das Wälzlager wirkenden mechanischen Kraft vollständig umschließt, wobei die Sensoraufnahmevorrichtung aus einem Kunststoff ausgebildet ist, der in einem flüssigen Zustand mit für den Sensor unschädlichen Eigenschaften, umfassend die Temperatur, verarbeitbar ist, und wobei die Sensoraufnahmevorrichtung eine kleinere Fließgrenze als der Sensor aufweist.According to claim 1 is in a rolling bearing with an outer ring, an inner ring and arranged therebetween rolling elements of the outer ring surrounded by an annular sensor receiving device, the at least an arranged within an axial extension of the outer ring sensor for Detecting one on the rolling bearing completely encloses acting mechanical force, wherein the sensor receiving device is formed from a plastic, in a liquid Condition with for the Sensor harmless Characteristics, including the temperature, is processable, and where the sensor receiving device has a lower yield point than the sensor.
Dadurch, dass die Sensoraufnahmevorrichtung den Sensor vollständig umschließt, wird dieser mit Vorteil vor Überlastungen geschützt. Weiterhin sind zum Aufnehmen der Sensoren keine aufwendig und kostenintensiv herzustellenden und mechanische Schwächungen verursachende Taschen oder Nuten am Außenring erforderlich. Dadurch, dass die Sensoraufnahmevorrichtung eine kleinere Fließgrenze als der Sensor aufweist, wird der Sensor insbesondere vor mechanischen Überlastungen und Beschädigungen geschützt. Die Sensoraufnahmevorrichtung umfasst dabei einen Kunststoff, der in einem flüssigen Zustand mit für den Sensor unschädlichen Eigenschaften, insbesondere hinsichtlich der Temperatur verarbeitbar ist, der im erwarteten Betriebstemperaturbereich des Wälzlagers einen festen Zustand aufweist und der im erwarteten Betriebsbelastungsbereich des Wälzlagers bei geringer Kriechempfindlichkeit elastisch verformbar ist. Als vorgenannter Kunststoff eignen sich dabei beispielsweise kaltaushärtende Expoxidharze.Thereby, that the sensor receiving device completely surrounds the sensor is this with advantage over overloads protected. Furthermore, to pick up the sensors are not complicated and expensive bags to be made and causing mechanical weakening or grooves on the outer ring required. Due to the fact that the sensor receiving device has a smaller size yield As the sensor has, the sensor is in particular against mechanical overloads and damage protected. The sensor receiving device comprises a plastic, the in a liquid Condition with for the sensor harmless properties, is processable in particular in terms of temperature, in the expected operating temperature range of the rolling bearing has a solid state and in the expected operating load range of the rolling bearing is elastically deformable at low creep sensitivity. When The aforementioned plastic are, for example, cold-curing epoxy resins.
In einer weiteren vorteilhaften Ausgestaltung weist die Sensoraufnahmevorrichtung einen kleineren Elastizitätsmodul als der Außenring auf. Dadurch wird bei Sensoren, die derart gestaltet sind, dass sie nicht unmittelbar auf eine an ihnen anliegende mechanische Spannung, sondern eine hierbei verursachte Verformung reagieren, insbesondere gegenüber Lösungen, bei denen die Sen soren unmittelbar mit dem vergleichsweise steifen Außenring verbunden wären, eine mit Vorteil deutlich erhöhte Feinfühligkeit des Sensoransprechens erzielt. Vorgenannte, auf eine Verformung reagierende Sensoren umfassen dabei beispielsweise eine durch die zu erfassende Verformung zu biegende Membran, die mit ihr fest verbundene balkenförmige Messaufnehmer mit verbiegt.In a further advantageous embodiment, the sensor receiving device a smaller modulus of elasticity as the outer ring on. This is in sensors that are designed so that they do not act directly on a mechanical stress applied to them, but a deformation caused thereby react, in particular across from Solutions, where the sen sors directly with the comparatively stiff outer ring would be connected, one with advantage significantly increased sensitivity achieved the sensor response. The above, on a deformation Reactive sensors include, for example, one through the deformation to be detected membrane to be detected, which is firmly connected with it bar-shaped Sensor with bends.
In einer weiteren vorteilhaften Ausgestaltung umfasst der Sensor ein piezoelektrisches Element. Dabei weist ein auf dem piezoelektrischen Effekt basierender Sensor insbesondere gegenüber einem auf einer elektrischen Widerstandsänderung basierenden Dehnungsmessstreifen mit Vorteil eine größere Messempfindlichkeit bei gleichzeitig geringerer Stoßempfindlichkeit in Verbindung mit einer höheren Temperaturunabhängigkeit auf.In a further advantageous embodiment the sensor comprises a piezoelectric element. In this case, a sensor based on the piezoelectric effect, in particular with respect to a strain gauge based on an electrical resistance change, advantageously has a greater measuring sensitivity with simultaneously lower shock sensitivity in conjunction with a higher temperature independence.
In einer weiteren vorteilhaften Ausgestaltung beinhaltet die Sensoraufnahmevorrichtung mehrere Sensoren. Damit kann eine Verteilung der Kräfte in Umfangsrichtung erfasst werden und/oder eine Genauigkeit des Erfassens durch die entsprechende Überbestimmung erhöht werden. Ferner können damit durch ein Vergleichen der Erfassungsergebnisse der Sensoren, beispielsweise von der Einbauumgebung herrührende unerwünschte Einflüsse, beispielsweise hinsichtlich der Temperatur und/oder der sich verändernden Lage der Wälzkörper zum jeweiligen Sensor ausgeglichen werden.In A further advantageous embodiment includes the sensor receiving device several sensors. This can be a distribution of forces in the circumferential direction be detected and / or accuracy of the detection by the appropriate over-determination elevated become. Furthermore, can thus by comparing the detection results of the sensors, for example, from the installation environment resulting undesirable influences, for example in terms of temperature and / or changing Position of the rolling elements for respective sensor can be compensated.
