Abstract

A helical winding unit is provided with a frame member in which a plurality of nozzle attachment units are provided to be aligned in a circumferential direction about an axis of a liner; nozzle units that each have a guide body movable in a radial direction of the liner and rotatable about a rotating axis extending in the radial direction, and that are attachable to and detachable from the nozzle attachment units; a moving endless toothed annular body that transmits, commonly to one or more nozzle units attached to one or more nozzle attachment units, power for moving the guide body in the radial direction; and a rotating endless toothed annular body that transmits, commonly to one or more nozzle units attached to one or more nozzle attachment units, power for rotating the guide body about the rotating axis.

First claim

The invention claimed is:

1. A filament winding device comprising a helical winding unit configured to helical-wind at least one fiber bundle onto a liner,
the helical winding unit including:
a frame member in which nozzle mounts are aligned in a circumferential direction centered at an axis of the liner;
at least one nozzle unit including a guide body that is attachable to and detachable from at least one of the nozzle mounts, the guide body being movable in a radial direction of the liner, rotatable about a rotational axis extending in the radial direction, and capable of guiding a plurality of fiber bundles to the liner;
an endless toothed annular body for moving, formed in an annular shape along the circumferential direction and configured to transmit power to all of the at least one nozzle unit attached to the at least one of the nozzle mounts, the power provided to move the guide body in the radial direction; and
an endless toothed annular body for rotating, formed in an annular shape along the circumferential direction and configured to transmit power to all of the at least one nozzle unit attached to the at least one of the nozzle mounts, the power provided to rotate the guide body about the rotational axis.

2. The filament winding device according to claim 1 , wherein the nozzle mounts include at least first nozzle mounts regularly provided at first angle intervals in the circumferential direction and at least second nozzle mounts regularly provided at second angle intervals in the circumferential direction, the second angle being larger than the first angle and not a multiple of the first angle.

3. The filament winding device according to claim 2 , wherein the first nozzle mounts are provided at 40 degree intervals in the circumferential direction, and the second nozzle mounts are provided at larger degree intervals than the 40 degree intervals in the circumferential direction.

4. The filament winding device according to claim 1 , wherein the endless toothed annular body for moving and the endless toothed annular body for rotating are ring gears.

5. The filament winding device according to claim 1 , wherein the endless toothed annular body for moving and the endless toothed annular body for rotating are endless belts, and the endless belts are wound onto pulleys each of which is able to transmit power from the endless belts to the at least one nozzle unit.

6. The filament winding device according to claim 1 , wherein a through hole is formed in the frame member to penetrate the frame member in an axial direction of the liner,
a part of the at least one nozzle unit attached to one side, in the axial direction, of the frame member passes through the through hole and reaches the other side of the frame member so that the at least one nozzle unit is able to receive power from one of the endless toothed annular body for moving and the endless toothed annular body for rotating which is provided on the other side of the frame member, and
the through hole is a slot formed across two or more of the nozzle mounts along the circumferential direction.

7. The filament winding device according to claim 6 , wherein a guide portion configured to guide the at least one nozzle unit along the circumferential direction is provided in the frame member.

8. The filament winding device according to claim 2 , wherein the endless toothed annular body for moving and the endless toothed annular body for rotating are ring gears.

9. The filament winding device according to claim 3 , wherein the endless toothed annular body for moving and the endless toothed annular body for rotating are ring gears.

10. The filament winding device according to claim 2 , wherein the endless toothed annular body for moving and the endless toothed annular body for rotating are endless belts, and the endless belts are wound onto pulleys each of which is able to transmit power from the endless belts to the at least one nozzle unit.

11. The filament winding device according to claim 3 , wherein the endless toothed annular body for moving and the endless toothed annular body for rotating are endless belts, and the endless belts are wound onto pulleys each of which is able to transmit power from the endless belts to the at least one nozzle unit.

12. The filament winding device according to claim 2 , wherein a through hole is formed in the frame member to penetrate the frame member in an axial direction of the liner,
a part of the at least one nozzle unit attached to one side, in the axial direction, of the frame member passes through the through hole and reaches the other side of the frame member so that the at least one nozzle unit is able to receive power from one of the endless toothed annular body for moving and the endless toothed annular body for rotating which is provided on the other side of the frame member, and
the through hole is a slot formed across two or more of the nozzle mounts along the circumferential direction.

13. The filament winding device according to claim 3 , wherein a through hole is formed in the frame member to penetrate the frame member in an axial direction of the liner,
a part of the at least one nozzle unit attached to one side, in the axial direction, of the frame member passes through the through hole and reaches the other side of the frame member so that the at least one nozzle unit is able to receive power from one of the endless toothed annular body for moving and the endless toothed annular body for rotating which is provided on the other side of the frame member, and
the through hole is a slot formed across two or more of the nozzle mounts along the circumferential direction.

14. The filament winding device according to claim 4 , wherein a through hole is formed in the frame member to penetrate the frame member in an axial direction of the liner,
a part of the at least one nozzle unit attached to one side, in the axial direction, of the frame member passes through the through hole and reaches the other side of the frame member so that the at least one nozzle unit is able to receive power from one of the endless toothed annular body for moving and the endless toothed annular body for rotating which is provided on the other side of the frame member, and
the through hole is a slot formed across two or more of the nozzle mounts along the circumferential direction.

15. The filament winding device according to claim 5 , wherein a through hole is formed in the frame member to penetrate the frame member in an axial direction of the liner,
a part of the at least one nozzle unit attached to one side, in the axial direction, of the frame member passes through the through hole and reaches the other side of the frame member so that the at least one nozzle unit is able to receive power from one of the endless toothed annular body for moving and the endless toothed annular body for rotating which is provided on the other side of the frame member, and
