Abstract

The invention provides a modularized wireless torque sensor device which comprises a friction wheel transmission shaft and an electrical module. The friction wheel transmission shaft comprises a transmission mandrel, a power input device and a power output device, the transmission mandrel is connected with the power input device and the power output device, and the power input and output devices rotate synchronously with the transmission mandrel; the power input device inputs power into the device sensor device via the transmission mandrel, and the power output device outputs power from the sensor device via the transmission mandrel; when the power output device bears a resistance from an outside driven member to generate a torque when outputting the power, the transmission mandrel is deformed, and a foil gauge measures a stress generated by deformation; and the electrical module comprises a control circuit PCB and a foil gauge, and the transmission mandrel and the control circuit PCBare connected with the foil gauge to collect stress data and sends the stress data to a far-end host computer. The torque sensor device is modularized, can be replaced rapidly, used flexibly and is wide in application range.

Description

technical field [0001] The invention relates to the field of electromechanical control, and relates to force feedback control, in particular to a modular wireless torque sensor device. Background technique [0002] The torque variation of mechanical power equipment is an important information of its operating condition. Torque testing is an indispensable content for various mechanical product development, quality inspection, optimal control, working condition monitoring and fault diagnosis. Regarding the equipment stress, especially the torque sensor, it has been widely used in the optimal design and intelligent control of the power drive system of various mechanical equipment. [0003] For the measurement of shaft torque, common methods include metal strain gauge type and non-contact type. [0004] The metal strain gauge type uses the deformation of the shaft to change the resistance value of the strain gauge on the shaft to measure the torque. For a torque sensor using ...
