[0020] Working principle: When in use, the staff first installs the measured shaft 5 on the force measuring spindle 4, and then starts the driving motor 3 to drive the measured shaft 5 on the force measuring spindle 4 to rotate, and measures the friction torque of the measured shaft 5 through the friction between the measured shaft 5 and the force sensor 6.
