[0012] The present invention also proposes an operating method of a bearing device with an online interlocking safety protection function, comprising the following steps: S1, first insert the thermal resistance detector into the mounting hole opened on the outside of the bearing box, so that the probe at the upper end of the thermal resistance detector is exposed from the inside of the bearing box, and then the plug at the lower end of the thermal resistance detector is stuck in the mounting hole, and then the other end of the wire is connected to the sensor, and the data is uploaded to the computer through the sensor; then the roller bearing, ball bearing and rotating shaft are installed in the bearing box in sequence, and then the rotating shaft is connected to the driving device, and the probe exposed inside the bearing box is installed through the roller bearing, so that the exposed probe is pushed back into the mounting hole, and the first spring is in a compressed state, and the upper end of the probe abuts against the outer surface of the roller bearing; S2, when the thermal resistance detector is installed, the drive device is connected to the wire and powered on, and then the drive device is started, and the shaft is connected through the output shaft of the drive device, so that the shaft rotates.

Therefore, when the temperature is too high, the thermal insulation sleeve and the metal heat dissipation wire can ensure that the temperature of the wire at the upper end of the thermal resistor detector is maintained at a stable value, which is convenient for uploading data and improving the stability of data during transmission. When the detection is completed, the drive device is powered off.

[0020] Working principle: In this embodiment, the present invention also proposes a method for using a bearing device with an online interlocking safety protection function, comprising the following steps: Step 1: first, insert the thermal resistance detector 7 into the mounting hole 6 opened on the outside of the bearing box 1, so that the probe 16 at the upper end of the thermal resistance detector 7 is exposed from the inside of the bearing box 1. At this time, the plug 8 at the lower end of the thermal resistance detector 7 is stuck in the mounting hole 6, and then the other end of the wire 24 is connected to the sensor, and the data is uploaded to the computer through the sensor; then the roller bearing 2, the ball bearing 3 and the rotating shaft 4 are installed in the bearing box 1 in sequence, and then the rotating shaft 4 is connected to the driving device 5. The probe 16 exposed inside the bearing box 1 is installed through the roller bearing 2, so that the exposed probe 16 is pushed back into the mounting hole 6. At this time, the first spring 12 is in a compressed state, and the upper end of the probe 16 abuts against the outer surface of the roller bearing 2; Step 2, after the thermal resistance detector 7 is installed, the drive device 5 is connected to the wire and powered on, and then the drive device 5 is started, and the shaft 4 is connected through the output shaft of the drive device 5, so that the shaft 4 rotates. At this time, the shaft 4 rotates in the roller bearing 2 and the ball bearing 3, thereby controlling the rotation of the rotor in the roller bearing 2 and the ball bearing 3, thereby generating heat, and then the temperature of the surface of the roller bearing 2 is detected by the thermal resistance detector 7, and then the data is uploaded to the computer through the wire 24 and the sensor; Step three, when the driving device 5 runs for a long time, the roller bearing 2 is always installed in the bearing box 1, and the first spring 12 will have elastic fatigue, so that the upper end of the probe 16 cannot abut against the outer surface of the roller bearing 2.

9. An operating method for a bearing device with an online interlocking safety protection function according to any one of claims 1 to 8, characterized in that: The following steps are involved: S1, first insert the thermal resistance detector (7) into the mounting hole (6) opened on the outside of the bearing box (1), so that the probe (16) at the upper end of the thermal resistance detector (7) is exposed from the inside of the bearing box (1), and then the plug (8) at the lower end of the thermal resistance detector (7) is stuck in the mounting hole (6), and then the other end of the wire (24) is connected to the sensor, and the data is uploaded to the computer through the sensor; then the roller bearing (2), the ball bearing (3) and the rotating shaft (4) are installed in the bearing box (1) in sequence, and then the rotating shaft (4) is connected to the driving device (5), and the probe (16) exposed inside the bearing box (1) is installed through the roller bearing (2), so that the exposed probe (16) is pushed back into the mounting hole (6), and at this time the first spring (12) is in a compressed state, and the upper end of the probe (16) abuts against the outer surface of the roller bearing (2); S2, when the thermal resistance detector (7) is installed, the drive device (5) is connected to the wire and powered on, and then the drive device (5) is started, and the rotating shaft (4) is connected through the output shaft of the drive device (5), so that the rotating shaft (4) rotates. At this time, the rotating shaft (4) rotates in the roller bearing (2) and the ball bearing (3), thereby controlling the rotation of the rotor in the roller bearing (2) and the ball bearing (3), thereby generating heat, and then the surface temperature of the roller bearing (2) is detected by the thermal resistance detector (7), and then the data is uploaded to the computer through the wire (24) and the sensor; S3, when the driving device (5) runs for a long time, the roller bearing (2) is always installed in the bearing box (1), and the first spring (12) will be elastically fatigued, so that the upper end of the probe (16) cannot abut against the outer surface of the roller bearing (2). At this time, the side wings on both sides of the fastener (9) are pinched, and then the rotating block (18) at the lower end is rotated, and the rotating block (18) is fixed to the lower end of the jacking cylinder (17), and then the jacking cylinder (17) is threadedly connected to the fastener (9). When the rotating block (18) rotates, the jacking cylinder (17) rises inside the fastener (9), thereby pushing the moving seat (10) upward, and then pushing the lower connecting ring (11) upward, so that the upper end of the probe (16) abuts against the outer side of the roller bearing (2). At this time, the length of the first spring (12) is shortened and it is in a compressed state; S4, when the temperature of the outer side of the roller bearing (2) is too high, the temperature of the surrounding air will diffuse and then enter the mounting hole (6), thereby increasing the temperature of the surrounding wire (24) at the upper end of the thermal resistor detector (7). The high temperature is isolated on the outside by the thermal insulation sleeve (26), and then the metal heat dissipation wire (27) is abutted against the thermal insulation sleeve (26). Therefore, when the temperature is too high, the thermal insulation sleeve (26) and the metal heat dissipation wire (27) ensure that the temperature of the upper end wire (24) of the thermal resistor detector (7) is maintained within a stable value, which is convenient for uploading data. When the detection is completed, the drive device (5) is powered off.
