The principle of the real-time pressure regulating device 22 is that when the diameter of the revolving body mechanical part 12 is reduced, the weight rod 33 is driven by gravity to move down the lower piston 30, so that the length of the spring set 31 is changed, the displacement can be reflected by the spring pressure sensor 32, because the lower piston 30 moves down, the pressure of the space surrounded by the upper piston 28 and the lower piston 30 is reduced, the tiny air pressure change phenomenon can be amplified by the thin tube 36, the air pressure change phenomenon is reflected by the air pressure sensor 40, and the rotation angle of the motor 26 is controlled by the two signals, and the pressure can be regulated only in a certain range due to unavoidable errors in the device, such as friction between the lower piston 30 and the cylinder 24, but the pressure can not be used as a measuring tool.
As shown in fig. 1, 9, 10, 11 and 12, the detecting device 41 includes a cantilever 42, a pressure-change measuring device 43, a hanging rod 44, a holder 45 and diamond balls 46, the cantilever 42 is disposed on the upper wall 2, the pressure-change measuring device 43 is disposed on the cantilever 42, one end of the hanging rod 44 is disposed on the pressure-change measuring device 43, the holder 45 is disposed at the other end of the hanging rod 44, and the diamond balls 46 are disposed in the holder 45.

Because of the reduction of the diameter of the rotary mechanical part 12, the position of the vertical rod 44 descends to pull the compound spring 49 to deform, while the nature of the compound spring 49 is a spiral coil with adjustable length, namely an inductor, the inductance corresponds to a resistor in an alternating current circuit, the impedance value of the inductor is related to the energizing frequency and the self inductance coefficient of the inductor, wherein the self inductance coefficient is related to the medium magnetic conductivity, the length, the number of turns and the coil area of the inductor, and the elongation condition of the inductor can be reversely pushed through the change of inductance under the condition that the alternating current power supply frequency and other self inductance coefficient related parameters are unchanged, namely the abrasion loss of the rotary mechanical part 12 is fed back.
When the rotary type electric motor is particularly used, a user firstly places the rotary mechanical part 12 in the friction rotor 9, then, under the output of an external motor, the driving gear set 16 rotates, and the friction rotor 9 rotates through the transmission of the gear ring 11, wherein the front end rotating circular ring 6 and the rear end rotating circular ring 7 can still be ensured to be subjected to supporting force in the rotation of the friction rotor 9.

After a certain period of time, the diameter of the rotary mechanical part 12 changes, the compound spring 49 stretches, so that the impedance of the compound spring is reduced, the abrasion condition of the rotary mechanical part 12 can be accurately measured, the whole working flow of the invention is just the process, and the process is repeated when the compound spring is used next time.
