The invention discloses a torque sensor. The torque sensor comprises a center shaft; the shaft sleeve assembly is fixed on the periphery of the middle shaft; the shaft sleeve assembly comprises a shaft sleeve body, a first control panel and a first coil, and the first control panel and the first coil are both installed on the shaft sleeve body. The disc claw assembly is arranged on the periphery of the middle shaft in a sleeving mode and is in transmission connection with the middle shaft, and the disc claw assembly comprises a strain gauge, a second control panel and a second coil; wherein the second control panel is configured to digitally encode a voltage signal output by the strain gauge and then generate a pulse position modulation signal; the duty ratio of each code element in the pulse position modulation signal is not greater than 1/3; the first control panel is configured to receive the pulse position modulation signal, decode the pulse position modulation signal and then output torque information. The torque sensor is low in cost and high in precision. In addition, the disc claw assembly and the shaft sleeve assembly can be matched at will, and manufacturability and maintainability are improved.
