Description

Technical Field

[0001] The utility model relates to the field of torque sensors, in particular to a non-contact torque sensor. Background Art

[0002] The non-contact torque sensor is also called a sliding variable resistor torque sensor. There are two pairs of magnetic pole rings in the non-contact torque sensor. When the input shaft and the output shaft rotate relative to each other, the air gap between the magnetic pole rings will change, which will cause the electromagnetic induction coefficient to change, generate an induced voltage in the coil, and convert the voltage signal into a torque signal. However, the existing non-contact torque sensors have certain inconveniences when used.

[0003] A non-contact magnetic coupling torque sensor is disclosed in the Chinese utility model patent application number: CN202121901756.5. A first circuit board and a second circuit board are arranged on the stator and the rotor. The first circuit board and the second circuit board are wirelessly powered by the second circuit board to the first circuit board through magnetic coupling. At the same time, the rotor transmits wireless data to the stator. By reading the data on the stator and calculating the data with a corresponding control algorithm, the torque value detected by the current sensor can be read. Compared with the traditional torque sensor, the utility model does not need to use coils and skeletons, and achieves the same effect through magnetic coupling between circuit boards, solving the problem of low accuracy and reliability of traditional non-contact torque sensors. However, the non-contact magnetic coupling torque sensor is not easy to disassemble and assemble during use. When the non-contact magnetic coupling torque sensor fails, it cannot be repaired in time. In addition, the non-contact magnetic coupling torque sensor has general stability and poor anti-seismic effect during use. It is easy to be affected by vibration during use. The monitoring effect, therefore, is proposed. Utility Model Content
