Embodiment 1
[0039] refer to Figure 1-4 , the present invention provides a technical solution:
[0040] Please refer to Figure 1-2 , a balance adjustment device for a single-stage disc of a turbofan engine rotor, comprising:
[0041] Balance base 1;
[0042] The eccentric adjustment assembly 2 installed on the balance base 1 and the support assembly 3 installed on the balance base 1;
[0043] A single-stage disc 4, the single-stage disc 4 is supported above the eccentric adjustment assembly 2, adjusts the distance between the eccentric adjustment assembly 2 and the center of the balance base 1, and moves the eccentric adjustment assembly 2 to the center of the balance base 1 through the support assembly 3 The single-stage disk 4 is connected with the balance base 1 to form a concentric structure up and down.
[0044]The balance adjustment device for the turbofan engine rotor single-stage disk of the present invention has few components, but it has good operability. When balancing, th...
Embodiment 2
[0061] A method for adjusting the balance of a single-stage disk of a turbofan engine rotor, using the balance device for a single-stage disk of a turbofan engine rotor for adjustment, including the following steps:
[0062] S1. Install the eccentric adjustment assembly 2: select a set of installation position units matching the diameter of the single-stage disk 4, and install four eccentric adjustment seats in the installation holes 6 of the installation position unit;
[0063] S2. Installing the supporting components 3: installing the four supporting components 3 in the mounting holes 6, and installing them on the same set of installation position units with the four eccentric adjustment seats, and alternately setting them with the eccentric adjusting components 2;
[0064] S3. Place the single-stage disk 4: support the single-stage disk 4 on the support head 203 of the eccentric adjustment assembly 2, measure the radial runout of the single-stage disk 4 to obtain the single-...
