Torque measuring shaft and measuring method

Abstract

The invention discloses a torque measuring shaft and a torque measuring method, which belong to the field of torque measuring tools, and solve the problems that the existing torque measuring device cannot feed back measured data in real time and errors exist in the measured data. The torque measuring shaft comprises a driving shaft and a shell body, wherein the driving shaft comprises a torque measuring section, the shell body coats the torque measuring section, a gap is formed between the shell body and the outer wall of the torque measuring section, and an electronic assembly is arranged inside the shell body; the electronic assembly comprises a battery, a strain gage, a power supply module, an analog-to-digital conversion module, a display screen module and a microprocessor module; the strain gage is arranged on the outer wall of the torque measuring section; the battery is in bidirectional connection with the power supply module; the power supply module is connected with the strain gage; the strain gage is connected with the analog-to-digital conversion module; the analog-to-digital conversion module is connected with the power supply module and the microprocessor module; and the microprocessor module is in bidirectional connection with the power supply module and in unidirectional connection with the display screen module. The torque measuring shaft can feed back measured data in real time, is accurate in measurement and has long service life.

Description

technical field [0001] The invention belongs to the field of torque measuring tools, and more specifically relates to a torque measuring shaft and a measuring method. Background technique [0002] In engineering, it is usually necessary to perform dynamic torque measurement on the rotating shaft. There are usually three types of torque measurement in the prior art, one is to use a dynamic torque sensor for measurement, the other is to use a strain gauge on the rotating shaft for measurement, and the other is to use a dynamic torque sensor for measurement. It is measured with a static torque sensor. The dynamic torque sensor is used for torque measurement. Due to the large size of the dynamic torque sensor and the need for special signal transmitters, acquisition and conditioning boxes, digital display instruments, etc., it is usually necessary to build a test bench to complete the torque measurement of the rotating shaft. Therefore, this torque measurement The method takes ...
