When the predetermined allowable value is exceeded, it can be judged that the clutch brake 20 is overheated, and it can be judged that there is no tightness between the pressure plate 21 and the friction plate of the clutch brake 20. Adsorption.

During the rotation of the flywheel 10, if the flywheel 10 is incorrectly tilted, eccentric, or interfered by foreign objects, it will cause the flywheel 10 to vibrate, and the first distance sensor 12 measures the vibration generated by the flywheel 10 and transmits it to The central processing unit 70 uses the central processing unit 70 to determine whether the vibration value measured by the first distance sensor 12 exceeds the predetermined vibration value. When the central processing unit 70 determines from the first distance sensor 12 When the measured vibration value exceeds the predetermined vibration value, it is determined that the flywheel 10 is incorrectly tilted, eccentric, or interfered with rotation by foreign objects.

When the main shaft 50 rotated by the flywheel 10 and the clutch brake 20 is in operation, if the main shaft 50 has eccentricity, twists, abnormal protrusions, etc., it will cause the main shaft 50 to vibrate abnormally during the rotation process, and the bearing 60 supports the main shaft 50, and when the main shaft 50 generates vibration, it is transmitted to the bearing 60. Therefore, the first vibration sensor 61 on the bearing 60 can detect the vibration generated by the main shaft 50 and transmit the vibration to the central processing unit 70. The central processing unit 70 determines whether the vibration value is higher than the predetermined vibration value, so as to determine whether the main shaft 50 is eccentric, bent, or abnormally protruding.

Finally, the decoder 51 detects the rotational speed of the spindle 50 and transmits the measured rotational speed to the central processing unit 70. The central processing unit 70 determines whether the rotational speed measured by the decoder 51 exceeds the predetermined rotational speed. To determine whether the rotation speed of the main shaft 50 is too slow.
