Title:
LOAD CELL AND BEARING
Document Type and Number:
WIPO Patent Application WO/2019/026655
Kind Code:
A1
Abstract:
Provided are: a load cell capable of accurately measuring a load in a thrust direction; and a bearing using the load cell. This load cell (1) is provided with: a deformable body (2); strain gauge sets (3a-3d) for detecting strain occurring in the deformable body (2). The deformable body (2) has: two annular flat plates (20a, 20b) arranged in the direction of an axis O; and a connection member (21) connecting the annular flat plates (20a, 20b). The connection member (21) comprises a plurality of arms (22) arranged on a circle centered on the axis O, the plurality of arms (22) being positioned at equal intervals and being line-symmetric with respect to the axis O, and the connection member (21) is tilted relative to the axis O. The strain gauge sets (3a-3d) each comprise four strain gauges (30a-30d) constituting a Wheatstone bridge circuit, and are attached to locations line-symmetric with respect to the axis O of the connection member (21).
