The device comprises a gauge stand 1, a first section dial indicator 5, a second section dial indicator 6 and an excircle dial indicator 7. The meter frame 1 can be arranged on a motor side coupler 11, and the concentricity of motor installation is adjusted through the readings of the first section dial indicator 5, the second section dial indicator 6 and the excircle dial indicator 7.

Specifically, the meter stand 1 is annular and has an inner diameter equal to the outer diameter of the motor-side coupling 11. The meter frame 1 is coaxially sleeved on the outer side of the motor side coupler 11.

Preferably, referring to fig. 2, the watch frame 1 comprises a first holding body 8 and a second holding body 9 having a circular arc shape. The first clamping body 8 and the second clamping body 9 are butted to form the watch frame 1. Connecting seats are fixedly arranged at the two ends of the first clamping body 8 and the two ends of the second clamping body 9, and connecting screw holes are formed in the connecting seats. When the first clamping member 8 is connected to the second clamping member 9, the connecting screw hole of the connecting seat of the first clamping member 8 is aligned to the connecting screw hole of the connecting seat of the second clamping member 9. At this time, the fastening bolt 10 is inserted into the connecting screw hole and fastened by the fastening nut, so that the first clamping body 8 and the second clamping body 9 can be fixedly connected.

Referring to fig. 1, one end of the third mounting arm 4 is welded to the outer side wall of the meter frame 1. The third mounting arm 4 is parallel to the axial direction of the meter base 1 and extends to the side where the fan-side coupling 12 is located. The lower end of the second mounting arm 3 is fixedly mounted at the end of the third mounting arm 4, so that the second mounting arm 3 is located on the side of the frame 1 facing the wind turbine side coupling 12. The first mounting arm 2 is fixedly connected with the meter frame 1 through a connecting arm parallel to the axis direction of the meter frame 1. One end of the connecting arm is welded to the outside of the case band 1. The upper end of the first mounting arm 2 is fixedly mounted at the end of the connecting arm, so that the first mounting arm 2 is also located on the side of the watch frame 1 facing the wind turbine side coupling 12.

Wherein the axis of the motor-side coupling 11 extends in the horizontal direction. The first mounting arm 2 and the second mounting arm 3 are located in the same vertical plane, and then the plane where the first mounting arm 2 and the second mounting arm 3 are located is perpendicular to the axis of the motor-side coupler 11.
