Abstract
A kind of reverse mechanism of mechanical watch automatic winding.By reverse wheel upper slice, reverse wheel bottom sheet, commutating tooth axle, commutation ratchet, commutation 2, ratchet and commutation axle sleeve composition.Reverse wheel bottom sheet and commutation ratchet and commutating tooth axle interference fit integral, commutation ratchet 2 is only contained between reverse wheel upper slice and reverse wheel bottom sheet, the nail clearance fit of commutation ratchet loads in the hole of reverse wheel upper slice, reverse wheel upper slice and reversing shaft overlap clearance fit, commutation axle sleeve and commutating tooth axle interference fit.When reverse wheel upper slice rotates counterclockwise, the thrust surface (A) that the commutation ratchet gear teeth withstand on commutation ratchet causes reverse wheel bottom sheet to rotate counterclockwise, and commutation ratchet swings up and down, two ends can with the gear teeth work of commutation ratchet; When reverse wheel upper slice rotates clockwise, the inclined-plane of the commutation ratchet gear teeth and commutation detent contact, can only make commutation ratchet two ends with commutation ratchet contact process in swing alternatively up and down, and reverse wheel bottom sheet can not be made to rotate, realize reverse wheel upper slice Double-directional rotary, reverse wheel bottom sheet can only the object of one-directional rotation.
Description
Art
The utility model relates to a kind of reverse mechanism of mechanical watch automatic winding, is especially convenient to processing and assembling, the commutation ratchet of reliable operation and commutation ratchet.
Background technology
At present, the reverse mechanism of known mechanical watch automatic winding has roller type and oscillating rod type.In roller type reverse mechanism, roller is normally processed by ruby, and simply, but cost is high, works not too reliable; In the reverse mechanism of oscillating rod type, part difficulty of processing is large, is difficult to produce in enormous quantities.
Summary of the invention
In order to improve the reliability of mechanical watch automatic winding institution staff, be convenient to produce in enormous quantities.The utility model provides a kind of reverse mechanism of mechanical watch automatic winding, by reverse wheel upper slice, and reverse wheel bottom sheet, commutating tooth axle, commutation ratchet, commutation 2, ratchet and commutation axle sleeve composition.Reverse wheel bottom sheet and commutation ratchet and commutating tooth axle interference fit integral, commutation ratchet 2 is only contained between reverse wheel upper slice and reverse wheel bottom sheet, the nail clearance fit of commutation ratchet is contained in the hole of reverse wheel upper slice, reverse wheel upper slice and reversing shaft overlap clearance fit, commutation axle sleeve and commutating tooth axle interference fit, commutating is realized by commutation ratchet and the ratchet that commutates.
The technical scheme in the invention for solving the technical problem is: design commutation ratchet, commutation ratchet, reverse wheel upper slice, commutation axle sleeve and commutating tooth axle.Reverse wheel bottom sheet and commutation ratchet and commutating tooth axle interference fit integral, commutation ratchet 2 is only contained between reverse wheel upper slice and reverse wheel bottom sheet, commutation ratchet bind in the hole of reverse wheel upper slice, reverse wheel upper slice and reversing shaft overlaps clearance fit, and commutate axle sleeve and commutating tooth axle interference fit.When reverse wheel upper slice rotates counterclockwise, the thrust surface (A) that the commutation ratchet gear teeth withstand on commutation ratchet causes reverse wheel bottom sheet to rotate counterclockwise, and commutation ratchet swings up and down, two ends can with the gear teeth work of commutation ratchet; When reverse wheel upper slice rotates clockwise, the inclined-plane of the commutation ratchet gear teeth and commutation detent contact, can only make commutation ratchet two ends with commutation ratchet contact process in swing alternatively up and down, and reverse wheel bottom sheet can not be made to rotate, realize reverse wheel upper slice Double-directional rotary, reverse wheel bottom sheet can only the object of one-directional rotation.
The beneficial effects of the utility model are, overcome roller type reverse mechanism cost high, work is not too reliable and oscillating rod type reverse mechanism part difficulty of processing is large, is difficult to the defect produced in enormous quantities, adopts commutation ratchet, commutation pawl structures, reliable operation, simple and practical, good manufacturability, commutation ratchet and commutation ratchet adopt mould one-shot forming, cost is low, reliable operation.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is working face figure of the present utility model.
Fig. 2 is Fig. 1 cut-open view.
In figure: 1. reverse wheel upper slice, 2. reverse wheel bottom sheet, 3. commutating tooth axle, 4. commutate ratchet, and 5. commutate ratchet, and 6. commutate axle sleeve.
Embodiment
In FIG, reverse wheel bottom sheet (2) and commutation ratchet (4) with commutating tooth axle (3) interference fit integral, 2 commutations ratchet (5) are contained between reverse wheel upper slice (1) and reverse wheel bottom sheet (2), the nail clearance fit of commutation ratchet (5) is contained in the hole of reverse wheel upper slice (1), reverse wheel upper slice (1) and commutation axle sleeve (6) clearance fit, commutation axle sleeve (6) and commutating tooth axle (3) interference fit.When reverse wheel upper slice (1) rotates counterclockwise, commutation ratchet (4) the gear teeth withstand on commutation ratchet (5) thrust surface (A) on cause reverse wheel bottom sheet (2) to rotate counterclockwise, commutation ratchet (5) swing up and down, two ends can with commutation ratchet (4) gear teeth work; When reverse wheel upper slice rotates clockwise, the inclined-plane of commutation ratchet (4) gear teeth contacts with commutation ratchet (5), can only make commutation ratchet (5) two ends with commutation ratchet (4) contact process in swing alternatively up and down, and reverse wheel bottom sheet (2) can not be made to rotate, realize reverse wheel upper slice Double-directional rotary, reverse wheel bottom sheet can only the object of one-directional rotation.
Claims (1)
