Title:
LOAD CELL AND BEARING
Document Type and Number:
Japanese Patent JP2019027958
Kind Code:
A
Abstract:
To provide a load cell capable of accurately measuring a load in a thrust direction and a bearing using this load cell.SOLUTION: A load cell 1 includes a strain gauge 2 and strain gauge sets 3a to 3d to detect distortions generated in the strain body 2. A deforming body 2 has two annular plates 20 a, 20b arranged in the direction of the axial center O and a connecting member 21 connecting between the annular plates 20a, 20b. The connecting member 21 is constituted by a plurality of arms 22 arranged at equal intervals with respect to the axial center O and linearly symmetrically with respect to the circumference of the axis O, and is inclined with respect to the axial center O. The strain gauge sets 3a to 3d consist of four strain gauges 3a to 3d forming the Wheatstone bridge circuit, and are attached to the axial center O of the connecting member 21 at a position linearly symmetrical with respect to the axial center O.SELECTED DRAWING: Figure 2
