When using the transition disc to connect the main shaft motor and the fan, it is necessary to ensure that the coaxiality is good during installation, so it is necessary to constantly measure and adjust during installation, making the installation process more complicated.

The adjusting plate increases the contact area between the calibration mechanism and the transmission shaft of the main shaft motor, improves the clamping stability of the transmission shaft, and further improves the installation accuracy of the transition disc.

[0011] Preferably, the adjusting plate is in an arc shape.

[0012] By adopting the above technical scheme, the arc shape further increases the contact area between the main shaft motor and the adjusting plate, thereby further improving the clamping stability of the transmission shaft and further improving the installation accuracy of the transition disc.

[0017] Preferably, the calibration mechanism is detachably connected with the transition disc, a clamping groove is formed in the transition disc, and the adjusting block is clamped with the clamping groove.

[0018] By adopting the above technical scheme, when the transition disc is connected with the main shaft motor, the calibration mechanism can be detached, thereby facilitating the connection of the transition disc with the fan.

[0019] Preferably, a limiting plate is arranged between adjacent adjusting blocks, and the two ends of the limiting plate are respectively connected with the two adjusting blocks.

[0020] By adopting the technical scheme, the limiting plates are connected to the plurality of adjusting blocks, thereby improving the convenience of mounting or dismounting the calibration mechanism, and improving the mounting efficiency of the transition disc.

[0021] Preferably, the opening of the clamping groove is provided with a first guide slope, and the adjusting block is provided with a second guide slope, and the first guide slope is parallel to the second guide slope.
