  • Publication number: 20220299389
    Abstract: The present disclosure discloses an anti-overload torque sensor based on thin film sputtering, which includes an output cable, a circuit board, a cushion column, a shell, an elastic body, strain beams and thin film strain gauges. The elastic body is an annular plate, which is sequentially divided into an inner edge section, a mounting ring section and an outer edge section from inside to outside, and the mounting ring section is provided with integrally formed rectangular protrusions as the strain beams. The shell is coaxially installed on the mounting ring section of the elastic body. The circuit board is located in an annular cavity of the shell and is installed on the mounting ring section of the elastic body through the cushion column. One end of the output cable is welded on the circuit board, and the other end is connected with an external electrical connector. Strain resistors of the two thin film strain gauges are sputtered on the strain beams of the elastic body by the sputtering coating technology.
