Specific implementation mode
Referring to Fig. 1 to Fig. 9, illustrating the arrangement of multiple bar shaped fins 4 first, it is assumed that the number of intermediate plate 13 is N, and N is even number,
The number of same slot 9 is also N, and the width of slot 9 is A, and multiple intermediate plates 13 are formed by the virtual of the lateral surface central point of circular cone ring
The radius of circle 16 is R, and the arc length of the central point of each intermediate plate 13 is C, then the ∏ R/N-A of C=2, and assumes the press section in nut A1
The medial surface of 3 circular cone ring is corresponding to M fin 4 of arrangement, the circle of the press section 3 of nut A1 in the range of the arc length C of intermediate plate 13
The virtual radius of circle of the medial surface central point of conical ring is R ', R=R ' in nut A1 and nut B6 processing, in adjacent fin 4
Axis spacing is B, then B=C/M, and the projection circle of the medial surface of the circular cone ring of the press section 3 of nut A1 is divided into 4 semicircles, i.e., flat
First, second, third, fourth quadrant of areal coordinate system, in fourth quadrant, since the number of slot 9 is even number, it is minimum there are two
The central axes of the fin 4 of the top are directed at Y-axis by slot 9 and the alignment of X-axis or Y-axis it is now assumed that being aligned with Y-axis there are one slot 9,
Remaining fin 4 is evenly arranged in by central axes spacing B in fourth quadrant；It, will be in the fin 4 of the top in first quartile
The distance of axis runout Y-axis half B, remaining fin 4 are evenly arranged in by central axes spacing B in first quartile；?
In two quadrant, the central axes of the fin 4 of right end are deviateed to the distance of X-axis a quarter B, remaining fin 4 is pressed between central axes
It is evenly arranged in the second quadrant away from B；In third quadrant, 1/8th B of Y-axis is deviateed into the central axes of the lowermost fin 4
Distance, remaining fin 4 is evenly arranged in by central axes spacing B in third quadrant；The installation process of nut is：First by nut
The press section 3 of A1 is tightened on bolt and makes the lower end workpiece pressing of nut A1 upward, then the clamping section 8 of nut B6 is twisted downward
On bolt and the clamping section 8 of nut B6 is made to hold out against the press section 3 of nut A1, multiple fins 4 of the press section 3 of nut A1 will squeeze
Multiple intermediate plates 13 of nut B6, the internal thread B14 of multiple intermediate plates 13 are pressed to squeeze the external screw thread of bolt, tightly by the external screw thread of bolt
It holds, considerably increases the internal thread B14 of multiple intermediate plates 13 and the externally threaded frictional force of bolt in this way, reach locking mesh
's；If the fin 4 of the top of nut A1 is just directed at the slot 9 of the top of nut B6, at least one fin 4 card
Enter in the slot 9 of nut B6, has realized interlocking；If the fin 4 of the top of nut A1 is not aligned with the top of nut B6
Slot 9, then continue to rotate clockwise the distance of 1/8th B of nut A1 either the distance of a quarter B or half B away from
From at least one same fin 4 is caught in the slot 9 of nut B6, realizes interlocking；After nut A1 and nut B6 is interlocked, vibrating
Under the action of load, nut B6 first loosens, and the fin 4 for being caught in the nut A1 in the slot 9 of nut B6 prevents nut B6 from loosening again, together
When nut B6 the tightly anchor ear of intermediate plate 13 external screw thread of bolt, this interaction mutually restricts and is achieved that locking mesh
's；It needs to illustrate：The width of slot 9 is 2 to 3 millimeters, and the width of 4 lower end of fin is 1.5 to 2.5 millimeters.
