Abstract

A winch is provided for taking or winding ropes, cables, and the like. The winch has a drum, a lower crown, a rope groove and an upper crown having a socket which has a fluted cavity. The fluted cavity is configured to cooperate with a pin of a winch handle, which when turned rotates the drum. In an embodiment, the fluted cavity has a groove having a canted coil spring positioned therein. The pin on the winch handle has a groove placed to correspond with the depth of the groove when placed into the socket. The combination allows the winch handle to latch to the winch and to resist unintended separation between the two.

Claims (23)

1. A rotary application assembly for torque transmission comprising a rotatable flange and a socket having an opening extending through the rotatable flange: said socket comprising a plurality of fluted surfaces and a groove intersecting each of the fluted surfaces and having a canted coil spring positioned therein; wherein said groove comprises a bottom surface and two side surfaces and said rotatable flange being rotatable by a shaft having corresponding fluted surfaces.

2. The rotary application assembly of claim 1 , further comprising a second groove intersecting each of the fluted surfaces in said socket.

3. The rotary application assembly of claim 2 , further comprising a second canted coil spring positioned in said second groove.

4. The rotary application of claim 2 , further comprising a shaft coupled to said socket and having fluted surfaces.

5. The rotary application of claim 1 , wherein said socket has a wall surface and wherein said bottom surface is angled to the wall surface of the socket.

6. The rotary application of claim 1 , wherein said rotatable flange is an upper crown of a capstan winch and said socket is formed with said rotatable flange.

7. The rotary application of claim 1 , wherein the socket has a configuration of at least one of a star shape geometry, a hexagon shape geometry, a polygon shape geometry, a diamond shape geometry, a triangle shape geometry, a rhombus shape geometry, a quadrilateral shape geometry, and a square shape geometry.

8. A winch comprising a drum having an upper crown and a socket, said socket comprising a plurality of fluted cavities and a groove intersecting each of the fluted cavities and having a canted coil spring positioned therein, said groove comprising a bottom surface and two side surfaces.

9. The winch of claim 8 , further comprising a winch handle.

10. The winch of claim 8 , wherein the drum comprises a groove for retaining a rope.

11. The winch of claim 8 , further comprising a second groove in said socket.

12. The winch of claim 8 , wherein the socket has a configuration of at least one of a star shape geometry, a hexagon shape geometry, a polygon shape geometry, a diamond shape geometry, a triangle shape geometry, a rhombus shape geometry, a quadrilateral shape geometry, and a square shape geometry.

13. The winch of claim 8 , wherein said socket has a wall surface and wherein said bottom surface is angled to the wall surface of the socket.

14. A method for transmitting a torque from a first component to a second component comprising:

inserting a shaft through a flange and into a socket, wherein said socket comprising fluted surfaces and a groove intersecting each of the fluted surfaces and said shaft comprising fluted surfaces and a groove;

rotating said shaft and said flange; and

wherein a canted coil spring is positioned between the groove of the shaft and the groove of the socket.

15. The method of claim 14 , wherein the groove comprises a bottom wall surface and two side wall surfaces.

16. The method of claim 14 , further comprising a second groove in said socket.

17. The method of claim 14 , wherein the flange is an upper crown of a capstan winch.

18. The method of claim 14 , wherein the socket has a configuration of at least one of a star shape geometry, a hexagon shape geometry, a polygon shape geometry, a diamond shape geometry, a triangle shape geometry, a rhombus shape geometry, a quadrilateral shape geometry, and a square shape geometry.

19. The method of claim 14 , wherein the spring is located in the groove of the shaft.

20. The method of claim 14 , wherein the spring is located in the groove of the socket.
