[0048] See also Figure 1 , including the following steps:

[0049] Step 1: Place the flange bearing body 3 to be tested close to the position of the shaft hole 2 on the fixing plate 1, and check whether the flange holes 4 on both sides can be assembled and positioned using two sets of adjusting assembly components 8 according to the size of the flange bearing body 3.

If not, use the pushing component 9 to adjust the distance between the two sets of adjusting assembly components 8, and then assemble the flange bearing body 3 using the two sets of adjusting assembly components 8;

[0050] Step 2: When one end of the upper end sleeve 6 of the scale display rod 5 is close to the inner shaft wall of the flange bearing body 3, the scale display rod 5 is relatively located at the center line position of the inner shaft of the flange bearing body 3, and after operating each set of supporting components 7 in turn, the scale display rod 5 is positioned against the inner shaft wall of the flange bearing body 3 by using the end sleeve 6 and the supporting components 7;

[0051] Step 3: Select a weight 11 and a hanging rope 10 of appropriate quality and hang them behind the outer wall of the scale display rod 5 (the whole is as shown in the figure). Figure 7 The scale-shaped detection of the deflection moment of the flange bearing body 3 is realized by cooperating with the scale lines on the outer wall of the scale display rod 5;

[0052] Among them, the principle of the detection process of the deflection torque of the flange bearing body 3 can refer to the content of the comparative document publication number: CN113916533A, which can be summarized as follows: define the maximum deflection torque as Fmax, the minimum deflection torque as Fmin, when the weight 11 is located at the Fmin scale of the minimum deflection torque, the flange bearing body 3 does not deflect, and when the weight 11 is located at the Fmax scale of the maximum deflection torque, the flange bearing body 3 deflects, then the surface of this flange bearing is qualified, otherwise the surface is unqualified;

[0053] For example, if the deflection torque range of a flange bearing body 3 is 30mN*m to 70mN*m, by adjusting the weight 11 to 30mN*m without deflection and 70mN*m, the deflection torque of the flange bearing body 3 can be determined to be qualified; and when making a single determination, if the deflection torque of a flange bearing body 3 is ≤50mN*m, then when the weight 11 is at 50mN*m, deflection occurs, indicating that the deflection torque value is qualified, otherwise it is unqualified;

[0054] During the deflection moment detection process of the flange bearing body 3 , when the positions of the suspension rope 10 and the weight 11 respectively meet the minimum deflection moment and the maximum deflection moment, the corresponding scale value position on the scale display rod 5 is immediately marked.

[0055] The implementation principle of the embodiment of the present application is as follows: when in use, first separate each nut member 86 from the insertion rod 84, then move the flange bearing body 3 close to the shaft hole 2 on the fixing plate 1, so that two of the upper and lower flange holes 4 are respectively plugged with the two insertion rods 84, and then reset each nut member 86 to achieve the assembly and positioning of the flange bearing body 3 on one side wall of the fixing plate 1;

[0056] While placing one end of the upper sleeve 6 of the scale display rod 5 close to the inner shaft of the flange bearing body 3, align the scale display rod 5 so that it is relatively located at the central axis position of the flange bearing body 3, and then use the paddles on each set of sleeves 72 to rotate on themselves, and then indirectly push each set of abutment blocks 73 to move linearly, so that each set of abutment blocks 73 is tightly abutted against the inner shaft wall of the flange bearing body 3 using the anti-slip pad 74;

[0057] Then, according to the detected deflection moment parameter range of the flange bearing body 3, a weight 11 of suitable mass is selected, and is suspended on the outer wall of the scale display rod 5 by the action of the suspension rope 10 (due to the plastic material of the scale display rod 5, the weight of the scale display rod 5 and the suspension rope 10 can be ignored), and the deflection moment of the flange bearing body 3 is detected in conjunction with the precise scale value on the scale display rod 5.

[0058] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
