Problems solved by technology

Therefore, in order to measure the output torque of the drilling rig in real time, the commonly used torque sensor cannot measure the output torque of the output device of the drilling rig because the base needs to be fixed. It is necessary to develop a torque sensor that can meet the requirements of rotation and linear motion.

Abstract

The invention provides a torque sensor approximately in a coupling flange shape. The torque sensor comprises a main body component and a circuit portion, wherein the main body component is internally used for measuring torque strain through a strain foil adhered in the middle of an elastomer, and then the circuit portion is used for conversion and wireless transmission of signals. The torque sensor has the advantages that the torque sensor is simple in structure and low in processing difficulty and cost; the torque sensor has functions of a coupler, can act synchronously with a measured part without adding a mounting base, is suitable for static and dynamic measurement and achieves real-time torque measurement on rotating machinery during actual production effectively.

Description

Technical field [0001] The invention relates to a torque sensor, which is suitable for on-line dynamic monitoring of torque of rotating power machinery. Background technique [0002] Torque is measured in rotating power machinery such as drilling machinery. It is an important working condition identification parameter for information acquisition. However, when drilling equipment is in operation, there is a lot of engineering information and it is difficult to collect. If the drilling equipment can be detected accurately, real-time and safely The average or instantaneous torque value will have important reference value for the development process of drilling equipment, testing and inspection, quality assurance, safety upgrade and optimization design. [0003] At present, as far as torque sensors are concerned, strain-type torque sensors are the most widely used at home and abroad, but such torque sensors usually need to be used with couplings and require high coaxiality during insta...
