Hole, simultaneously because gap is smaller, in use, the impact between stop pin 4 and hole is smaller, will not make to people and ring flange
At damage.By Strength co-mputation, the pin of φ 15 fully meets the demand of anti-counter-force at this.
T-slot device is designed in torsional stop 3, the milling of anti-rotation pin head part is flat, can be free to slide in T-slot, then must
It must determine a reasonable sliding stroke, any cooperation direction of ring flange 10 and odd-side main shaft 11 can be compatible with；It can from Fig. 2
To find out, when any one bolt through-hole center draws a straight line with two bolt-centers on ring flange 10, apart from via hole
Close bolt and via hole center are away from being L1, apart from remote bolt and via hole center away from for L2, then on any direction, via hole and bolt
Center away from L all in the section that L1 and L2 are constituted, i.e. L1≤L≤L2, it is contemplated that the modification part of ring flange, L1 and L2 is appropriate
Amplification, this defines the sliding strokes of stop pin.
