During automatic winding, automatic top drives driving wheel to rotate, and driving wheel band pawl rotates together, convex inside commutation ratchet Rise and contradicted with the inner bulge of ratchet, so that ratchet is swung out, described ratchet tail end contradicts with stop surface, to drive commutation Pawl wheel;
During hand winding, hand winding mechanism engages with the outer toothed portion that commutation ratchet is provided with and drives its rotation, ratchet tail End slips over from even surface surface.
The upper bar structure of said structure, because the side wall of the mounting groove in commutation ratchet is provided with bar helical teeth on multiple, and The side of upper bar helical teeth is even surface, and opposite side is stop surface, and the even surface top to stop surface top distance with only Block face bottom to the distance on stop surface top ratio be 0~1.3 so that ratchet by driving wheel drive rotate when, commutating Under the cooperation of ratchet internal protrusion, the tail end of ratchet contacts with stop surface, realizes that driving wheel takes commutation pawl wheel to, so as to real Existing automatic winding;And when hand winding mechanism drives commutation pawl wheel, when carrying out bar, the tail end of ratchet is from even surface surface Slip over, will not be rotated together with pawl, so as to the phenomenon of winged top would not also occur.
Further, in order to simplify structure, convenient installation, the mounting groove is rounded, and side wall uniform intervals are provided with multiple Upper bar helical teeth, and the even surface of two neighboring upper bar helical teeth is adjacent with stop surface.
Further, in order to simplify structure, convenient processing and assembling, the driving wheel is provided with the dress being engaged with pawl axis Distribution;Also for facilitating and contacted with ratchet inner bulge, the ratchet can be swung by center of rotation of pawl axis.
Further, contacted in order that obtaining with ratchet inner bulge well, the commutation ratchet internal protrusion and upper bar are oblique Number of teeth amount is identical, and is smoothly connected by the arc surface of indent between adjacent commutation ratchet internal protrusion.
Further, it is one-piece for the ease of processing, the commutation ratchet internal protrusion.
Further, for the ease of processing, the even surface and stop surface are integrally formed;The upper bar helical teeth, change It is integrally formed to ratchet internal protrusion and commutation ratchet.
The invention will be further described with specific embodiment below in conjunction with the accompanying drawings.

Embodiment
In order to more fully understand the technology contents of the present invention, technical scheme is entered with reference to specific embodiment One step introduction and explanation, but it is not limited to this.
As depicted in figs. 1 and 2, the wheeled automatic winding structure of a kind of commutation for mechanical watch movement, including driven tooth Axle 10, fixed cover are located at the commutation ratchet 20 of driven tooth axle 10, the ratchet 30 being embedded in the mounting groove 21 of commutation ratchet 20, use In the driving wheel 40 of be hinged fixed pawl 30, and for rotating the fixed main shaft 50 of connection driven tooth axle 10 and driving wheel 40; The commutation ratchet internal protrusion 22 for acting on ratchet inner bulge 31 is provided with the center of mounting groove 21, side wall is provided with upper bar helical teeth 23;Ratchet 30 is between commutation ratchet internal protrusion 22 and upper bar helical teeth 23;The side of upper bar helical teeth 23 is even surface 231, Opposite side is stop surface 232;Distance and stop surface 232 bottom to stop surface of the top of even surface 231 to the top of stop surface 232 The ratio of the distance on 232 tops is 0~1.3;The front end of ratchet 30 is provided with the pawl axis 32 being connected with driving wheel 40, ratchet 30 Tail end is automatic winding force side;Driving wheel 40 is provided with the pilot hole 41 being engaged with pawl axis 32;Ratchet 30 can be with pawl axis 32 be that center of rotation is swung.
During automatic winding, automatic top drives driving wheel 40 to rotate, and driving wheel 40 rotates together with pawl 30, and commutate ratchet Internal protrusion 22 contradicts with ratchet inner bulge 31, so that ratchet 30 is swung out, the tail end of ratchet 30 contradicts with stop surface 232, To drive commutation ratchet 20 to rotate;
During hand winding, hand winding mechanism engages with the outer toothed portion that commutation ratchet 20 is provided with and drives its rotation, ratchet 30 tail ends slip over from smooth 231 surfaces.
Specifically, mounting groove 21 is rounded, side wall uniform intervals are provided with 7 upper bar helical teeth 23, and two neighboring upper bar is oblique The even surface 231 of tooth 23 is adjacent with stop surface 232;Certainly the quantity of upper bar helical teeth 23 is at least provided with one.
Further, in other embodiments, the ratchet internal protrusion 22 that commutates is identical and adjacent with the upper quantity of bar helical teeth 23 Commutation ratchet internal protrusion 22 between be smoothly connected by the arc surface of indent.
Further, in other embodiments, the ratchet internal protrusion 22 that commutates is one-piece.
Further, in other embodiments, even surface 231 and stop surface 232 are integrally formed;Upper bar helical teeth 23, commutation Ratchet internal protrusion 22 and commutation ratchet 20 are integrally formed.
In summary:The upper bar structure of said structure, because the side wall of the mounting groove 21 in commutation ratchet 20 is provided with multiple Upper bar helical teeth 23, and the side of upper bar helical teeth 23 is even surface 231, and opposite side is stop surface 232 so that ratchet 30 is being led When driving wheel 40 drives rotation, under the cooperation of commutation ratchet internal protrusion 22, the tail end of ratchet 30 contacts with stop surface 232, real Existing driving wheel 40 takes commutation ratchet 20 to and rotated, so as to realize automatic winding;And when hand winding mechanism drives commutation ratchet 20 Rotating, when carrying out bar, the tail end of ratchet 30 slips over from the surface of even surface 231, will not be rotated together with pawl 30, so as to The phenomenon of winged top would not occur.
The upper bar structure of said structure, when carrying out bar to wrist-watch, commutation ratchet 20 all rotates counterclockwise, according to machine When the concrete structure of tool wrist-watch, the position of even surface 231 and stop surface 232 can also be inverted, then carry out upper bar to wrist-watch, change It is exactly to rotate clockwise to ratchet 20.
The above-mentioned technology contents that the present invention is only further illustrated with embodiment, in order to which reader is easier to understand, but not Represent embodiments of the present invention and be only limitted to this, any technology done according to the present invention extends or recreation, by the present invention's Protection.Protection scope of the present invention is defined by claims.
