D=0.5L+0.02D+0.2W+0.1,
Wherein, d indicates the aperture for matching repeated hole, and D1 indicates that the outer diameter of ring body, D2 indicate that the internal diameter of ring body, L indicate ring body
Axial length, W indicate the ring width of ring body.
The design of balancing loop including the following steps:
(1) determine that the outer diameter D 1 of ring body, the outer diameter D 1 of ring body are equal to 1.1~1.3 times of knife handle outer diameters;
(2) determine the internal diameter D2 of ring body, the internal diameter D2 and knife handle crest clearance of ring body cooperate, the grade of tolerance be H8 or
H10;
(3) the width W, 2W=D1-D2 of ring body are determined;
(4) axial length L of ring body is determined, the axial length of ring body is equal to the axial length of 0.10-0.13 knife handle;
(5) the aperture d, d=0.5L+0.02D+0.2W+0.1 for matching repeated hole are determined.
It include as follows using balancing loop adjustment knife handle/cutterhead center of gravity method so that the quantity with repeated hole is 30 as an example
Step:
(1) balancing loop is sleeved on knife handle, and with knife handle clearance fit;
(2) jackscrew of 4 0.3g is installed on in repeated hole, one is installed every an angle of 90 degrees, due to clearance fit, jackscrew
It withstands knife handle and also acts as the effect that balance ring is fixed on to knife handle;
(3) knife handle component/cutter head assembly center of gravity is tested using barycenter test instrument, enables the weighting position measured for the first time
It is set to the first weighting position, the weighting amount measured for the first time is the first weighting amount;
(4) the first weighting amount at position is laid particular stress on according to first measured, if first lays particular stress on 4 that position is installed in step 2
Some position in a jackscrew, then corresponding jackscrew here of dismantling, tests knife handle component/cutterhead using barycenter test instrument
The center of gravity of component, enabling second of weighting amount measured is the second weighting amount;It is combined according to the size of the second weighting amount is corresponding
The jackscrew of five kinds of weight specifications of installation or disassembly;
(5) the weighting amount at position is laid particular stress on according to first measured, if first lays particular stress on 4 that position is not installed in step 2
Any one of jackscrew position, then the top for laying particular stress on the opposite installation dimension at position first according to the first weighting amount
Silk;
(6) step 4, step 5 are repeated until knife handle component/cutter head assembly center of gravity and knife handle are axially coincident.
