[0022] Example 1.

[0023] Preferably, the sensor for measuring the pendulum of the bearing is used to calibrate the bearing (not shown in the figure). The sensor for measuring the pendulum of the bearing includes a central component 100 and a first calibration component 200. The first calibration component 200 is located on one side of the central component 100, wherein:

[0024] The center assembly 100 includes a center piece 110 and two first-direction positioning rods 120. One end of the first-direction positioning rod 120 is symmetrically inserted into and fixedly connected to the center piece 110. The other end of the first-direction positioning rod 120 extends from the center piece 110 to facilitate rotational connection with the first U-shaped piece 210.

[0025] The first verification assembly 200 includes a first U-shaped member 210, a first fixing ring 220, a first fixing rod 230 and a first bearing positioning member 240. One end of the first fixing rod 230 is inscribed in the first fixing ring 220 and (the end of the end) is further inscribed in the first U-shaped member 210; so that the first fixing rod 230 can rotate relative to the first U-shaped member 210; the first U-shaped member 210 is rotatably connected to the first direction positioning rod 120; so that the first verification assembly 200 can rotate as a whole relative to the first direction positioning rod 120 ; The first bearing positioning member 240 is detachably mounted on the first fixed rod 230, so that the bearing to be tested is mounted on the first bearing positioning member 240, and the corresponding first bearing positioning member 240 can be replaced according to bearings of different sizes; ultimately, the bearing to be tested has two degrees of freedom, which can rotate synchronously with the first fixed rod 230, and can also rotate back and forth with the first testing component 200 relative to the first direction positioning rod 120, better simulating the actual operating state of the bearing and more comprehensively covering the factors that may affect the bearing swing.

[0026] Among them, the central component 100 also includes two second direction positioning rods 130, which are arranged orthogonally to the first direction positioning rod 120. One end of the second direction positioning rod 130 is symmetrically inserted into the central piece 110 and fixedly connected to the central piece 110; so that the other end of the second direction positioning rod 130 extends from the central piece 110, which is convenient for rotational connection with the second U-shaped piece 310.

[0027] Among them, the sensor for measuring the bearing swing also includes a second verification component 300, which is located on the other side of the central component 100. The second verification component 300 includes a second U-shaped part 310, a second fixing ring 320, a second fixing rod 330 and a second bearing positioning part 340. One end of the second fixing rod 330 is inscribed in the second fixing ring 320 and (the end of the end) is further inscribed in the second U-shaped part 310; so that the second fixing rod 330 can rotate relative to the second U-shaped part 310; the second U-shaped part 310 is rotatably connected to the second direction positioning rod 130; so that the second verification Assembly 300 is capable of rotating as a whole relative to second directional positioning rod 130; second bearing positioning member 340 is removably mounted on second fixed rod 330, allowing the bearing to be tested to be mounted on second bearing positioning member 340, and the corresponding second bearing positioning member 340 can be replaced according to bearings of different sizes. Ultimately, the bearing to be tested has two degrees of freedom, allowing it to rotate synchronously with second fixed rod 330 and to rotate back and forth with second testing assembly 300 relative to second directional positioning rod 130, better simulating the actual operating state of the bearing and more comprehensively covering factors that may affect the bearing's swing. First testing assembly 200 and second testing assembly 300 do not interfere with each other and can operate simultaneously or independently.

[0028] Among them, the first verification component 200 also includes four first positioning pins 250, which pass through the first fixing ring 220 until they abut against the end of the first fixing rod 220; so as to better limit the first fixing rod 220, improve the rotation accuracy of the first fixing rod 220, and provide the necessary conditions for verifying the bearings positioned on the first fixing rod 220.

[0029] Among them, the second verification component 300 also includes four second positioning pins 350, which pass through the second fixing ring 320 until they abut against the end of the second fixing rod 320; so as to better limit the second fixing rod 320, improve the rotation accuracy of the second fixing rod 320, and provide the necessary conditions for verifying the bearings positioned on the second fixing rod 320.

[0030] Among them, the first fixing rod 230 has a first fixing rod tooth groove 231, which is located at the end of the first fixing rod 230 away from the first U-shaped member 210, so that the first fixing rod 230 is connected to an external rotating device, and then the external rotating device drives the first fixing rod 230 to rotate.

[0031] Among them, the second fixing rod 330 has a second fixing rod tooth groove 331, which is located at the end of the second fixing rod 330 away from the second U-shaped member 310, so that the second fixing rod 330 is connected to an external rotating device, and then the external rotating device drives the second fixing rod 330 to rotate.
