TORQUE SENSOR

摘要

Disclosed is a torque measuring sensor which has a simple structure and is capable of precisely measuring torque. The torque measuring sensor according to the present invention comprises a first rotary body having a ring type elastic module having an opening part on one side, a first rotary axis formed in an axial direction of the elastic module, a fixated module formed to be extended from one end of the opening part of the elastic module to the first rotary axis and a separation module extended from the other end of the opening part of the elastic module and formed to be separated from the fixated module; a second rotary body coupled to one side of the first rotary body to perform a rotational operation by torque; a torque transmission part transmitting the torque applied to the second rotary body to the separation module of the first rotary body; and a torque measuring part having a condenser changing a capacity according to a size of the opening part of the first rotary body, a power module applying power to the condenser and a calculation module measuring the capacity of the condenser to which the power is applied and calculating torque applied to the second rotary body using the measured capacity, thereby precisely measuring torque caused by an external force.
