Low profile load transducer

摘要

A load transducer includes a central body portion; a plurality of beams extending outwardly from the central body portion, each of the plurality of beams including an end portion that is supported in a cantilevered manner from the central body portion; and a plurality of load cells, each of the load cells being disposed on one of the beams, the plurality of load cells configured to measure a plurality of force and/or moment components. In addition to being very accurate and reliable, the load transducer has a low profile and small size. This invention is easily manufactured using strain gage technology.

主权项

1. A load transducer comprising, in combination:
a central body portion having a plurality of sides; a plurality of beams extending outwardly from the sides of the central body portion, each of the plurality of beams being supported in a cantilevered manner from the central body portion, one or more of the plurality of beams comprising a first top surface that is disposed at a first elevation relative to a bottom surface of the central body portion and a second top surface that is disposed at a second elevation relative to the bottom surface of the central body portion, the second elevation being greater than the first elevation, and wherein a recessed area created by the difference in elevation between the second elevation and the first elevation is used to accommodate one or more load cell electrical components; and a plurality of load cells, each of the load cells being disposed on one of the beams, the plurality of load cells configured to measure one or more force components or one or more moment components, or both one or more force components and one or more moment components.
