Abstract
Official abstract text for this publication.
The invention relates to a load measuring device including a deformable component configured to be deformed under a load to be measured and a sensor assembly attached to a first portion of the deformable component and to a method for determining load using such a sensor assembly. It is proposed that the sensor assembly includes at least one acceleration sensor configured to detect a change in an orientation of the first portion with regard to the direction of gravity and that the deformable component is formed as a seal configured to be in sliding contact with a component configured to rotate in relation to the seal.
First claim
Opening claim text (preview).
1 . A load measuring device including a deformable component configured to be deformed under a load to be measured and a sensor assembly attached to a first portion of the deformable component, wherein the sensor assembly includes at least one acceleration sensor configured to detect a change in an orientation of the first portion with regard to the direction of gravity, and wherein the deformable component is formed as a seal configured to be in sliding contact with a component configured to rotate in relation to the seal. 2 . The load measuring device according to claim 1 , wherein the seal has a profile with an inclined portion connecting a fixing portion of the seal supported by a metallic flange with a contact portion of the seal. 3 . The load measuring device according to claim 1 , wherein the component configured to rotate in relation to the seal is an inner ring of a bearing. 4 . The load measuring device according to claim 1 , wherein the component configured to rotate in relation to the seal is a rotating shaft. 5 . The load measuring device according to claim 1 , wherein the acceleration sensor is formed as a semiconductor based 3-axis acceleration sensor. 6 . The load measuring device according to claim 1 , wherein the sensor assembly includes at least two acceleration sensors attached to different portions of the component. 7 . The load measuring device according 6 , wherein the deformable component is a torque bar, wherein the two acceleration sensors are attached to opposite ends of the torque bar. 8 . The load measuring device according to claim 1 , further comprising a data processing device configured to calculate a load acting on the deformable component based on the signals obtained from the sensor assembly. 9 . A method for determining a load acting on a deformable component, the method comprising the steps of: using signals of an acceleration sensor to determine the load, attaching the acceleration sensor is attached to a first portion of the component in order to detect a change in an orientation of the first portion with regard to the direction of gravity, wherein the deformable component is formed as a seal configured to be in sliding contact with a component configured to rotate in relation to the seal.
