[0002] The fan main bearing is one of the core components of the fan, and its main functions are to support the fan blades, transmit power, bear loads and rotate. Specifically, the fan main bearing bears and transmits the huge axial and radial loads generated by the conversion of wind energy. Its strength, rigidity, and operating balance must be guaranteed to cope with the considerable load and inertia force. The fan main shaft bearing plays a vital role in the operation of the fan. When the main bearing is displaced beyond the preset safety range, the fan is prone to failure and damage. It is necessary to detect the displacement of the fan main bearing. The existing detection method usually uses an alarm and detection device with a displacement sensor for detection. The displacement sensor is easily affected by the shaking factor of the fan itself, resulting in low accuracy in the detection of the displacement of the fan main bearing. At the same time, when the alarm and detection device is installed on the fan by bolts, the vibration during the operation of the fan is likely to cause the bolts to loosen, affecting the overall stability, and there are certain disadvantages in the use process.

[0043] During use, when the second roller 103c-2 contacts the fan main shaft 202, when the fan main shaft 202 is offset, the self-reciprocating extrusion assembly 103 protrudes away from the center of the circle, thereby causing the first roller 103c-1 to squeeze the soft annular pad 102e and cause the soft annular pad 102e to deform, and the press-on quick-close 201a arranged on the soft annular pad 102e contacts the alarm light 201b fixedly arranged in the through hole 102a-1, and the alarm light 201b lights up, so that the operator can know the status of the fan main shaft 202 in time.
