[0056] Example: such as figure 1 As shown, the adjustment method of the present invention comprises the following steps:
[0057] Step 1: Install an online dynamic balancing system, such as Figure 8-Figure 11 shown;
[0058] Step 1.1: Place the dynamic balancing device in the inner hole of the main shaft 19, fix the expansion ring 1 firmly and fix the dynamic balancing device in the inner cavity of the main shaft 19, and ensure that the dynamic balancing device is concentric with the rotation center of the main shaft 19;
[0059] Step 1.2: Fix the two acceleration sensors I18 and II22 on the main shaft sleeve 20 respectively, the plane formed by the center line of the two acceleration sensors and the axis of the main shaft 19 is perpendicular to the horizontal plane, and measure the distance between the acceleration sensor and the main shaft sleeve 20 - a fixed point The distance is l 2 , l 6 ;
[0060] Step 1.3: install the phase sensor 25 horizontally, set it at the ce...
