Abstract
A load cell in accordance with the present invention comprises an insert defining a hub having a central opening dimensioned to receive a shaft. The insert is removably fixed to the shaft, and a cylindrical sleeve is configured and dimensioned to surround the insert. The sleeve is machined with interior notches. The insert is suspended and rotatably fixed within the sleeve by flanges which are integral with and project from the insert's hub into the sleeve's interior notches. The flanges are configured to respond with deformation to forces applied to the shaft, and strain gauges bonded to the flanges exhibit changes in resistance according to the degree of flange deformation.
